the number of subscribers, S, to a magazine increases by 21 percent each year. if the current number of subscribers is 3000

Answers

Answer 1

The number of subscribers after 3 years would be approximately 4624.109.

The given problem can be solved using the exponential growth formula.

That is, when the growth factor remains constant and the quantity multiplies by the growth factor in a given time, the formula for exponential growth can be used to find the answer.

The exponential growth formula is given by:  P(t) = P₀(1 + r)^t

where  P₀  is the initial amount, r is the annual interest rate as a decimal and `t` is the number of years.

So, for the given problem:  The current number of subscribers `P₀` is 3000.

The percentage increase in the number of subscribers is 21%.

Therefore,  r = 21/100 = 0.21.

So, the formula for the given problem is

S(t) = 3000(1 + 0.21)^t.

Now, to find the number of subscribers after 3 years, substitute t = 3.

So, the number of subscribers after 3 years would be:

S(3) = 3000(1 + 0.21)^3 = 3000(1.21)^3 = 4624.109.

Hence, the number of subscribers after 3 years would be approximately 4624.109.

PLEASE HELP FAST!! WILL GIVE BRAINLIEST! The rectangle ABCD has diagonals that intersect at point O and ABD = 30. Find BC if AC = 16 in

Answers

The length of BC in the rectangle ABCD is 16 units.

To find the length of BC in the rectangle ABCD, we can use the properties of rectangles and the intersecting diagonals.

Let's consider the given information:

AC = 16 (given)

ABD = 30° (given)

In a rectangle, the diagonals are equal in length. Therefore, AO = CO and BO = DO.

Since ABD is a right triangle, we can use trigonometric ratios to find the length of AO. In triangle ABD, the angle ABD is 90°, and we know ABD = 30°. Therefore, the remaining angle BDA is 180° - 90° - 30° = 60°.

Using the trigonometric ratio for a right triangle:

sin(BDA) = AO / AB

sin(60°) = AO / AB

√3 / 2 = AO / AB

Since AB is the length of the diagonal of the rectangle, we can represent it as d:

√3 / 2 = AO / d

Now, we can find AO:

AO = (√3 / 2) * d

Since AO = CO and BO = DO, we can conclude that BO and CO also have lengths of (√3 / 2) * d.

Now, let's consider triangle AOC. We know that AC = 16, and AO = CO = (√3 / 2) * d. We can use the Pythagorean theorem to find OC:

OC^2 = AC^2 - AO^2

OC^2 = 16^2 - [(√3 / 2) * d]^2

OC^2 = 256 - (3/4) * d^2

OC = √(256 - (3/4) * d^2)

Similarly, in triangle BOC, we have BO = (√3 / 2) * d and OC = √(256 - (3/4) * d^2). We can again use the Pythagorean theorem to find BC:

BC^2 = BO^2 + OC^2

BC^2 = [ (√3 / 2) * d ]^2 + [ √(256 - (3/4) * d^2) ]^2

BC^2 = (3/4) * d^2 + 256 - (3/4) * d^2

BC^2 = 256

Taking the square root of both sides:

BC = √256 = 16

Therefore, BC = 16.

So, the length of BC in the rectangle ABCD is 16 units.

Ms. Ling purchases a new car for $32,000 and finances it with a 6-year simple interest loan at an annual rate of 4. 25%. What are Ms. Ling’s monthly car payments

Answers

Ms. Ling's monthly car payments are $558.89.

The formula for calculating simple interest is:

Interest = Principal × Rate × Time

Given:

Principal (P) = $32,000

Rate (R) = 4.25% per year = 0.0425 (as a decimal)

Time (T) = 6 years

Using the formula, we can calculate the interest:

Interest = $32,000 × 0.0425 × 6

Interest = $8,160

The total amount to be repaid is the sum of the principal and the interest:

Total amount = Principal + Interest

Total amount = $32,000 + $8,160

Total amount = $40,160

To find the monthly car payments, we divide the total amount by the number of months in the loan term.

There are 6 years in the loan term, we multiply by 12 to convert it to months:

Number of months = 6 years × 12 months/year

Number of months = 72 months

Monthly car payments = Total amount / Number of months

Monthly car payments = $40,160 / 72

Monthly car payments = $558.89

Therefore, Ms. Ling's monthly car payments are approximately $558.89.

Answers

The distance between points (11,3) and (4,3) on a coordinate plane is 7 units.Let's understand the concept of distance between two points on a coordinate plane and how to find the distance between them.

A coordinate plane is a 2-dimensional number plane, with each point in the plane being represented by a pair of numbers (x, y) called its coordinates. When two points in a coordinate plane are given, the distance between them can be found using the distance formula. The formula is given below:Distance formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$Here, $(x_1, y_1)$ and $(x_2, y_2)$ are the coordinates of the given points.

So, to find the distance between points (11,3) and (4,3) on a coordinate plane, we will substitute these values in the above formula:Distance formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$Where, $(x_1, y_1) = (11,3)$ and $(x_2, y_2) = (4,3)$Therefore, we have:Distance formula: $d=\sqrt{(4-11)^2+(3-3)^2}$= $\sqrt{(-7)^2+(0)^2}$= $\sqrt{49}$= 7 unitsThus, the distance between points (11,3) and (4,3) on a coordinate plane is 7 units.

how is duplicating an angle different to a line segment

Answers

Duplicating an angle involves constructing an angle that has the same measure as the original angle. It can be done using a compass and a straightedge, following specific constructions. On the other hand, a line segment duplication refers to creating an identical copy of a given line segment, typically by using a ruler or other measuring tools.

Duplicating an angle is based on the concept of angle congruence, where two angles are considered congruent if they have the same measure. To duplicate an angle, one can use a compass to transfer the angle's measure onto another location or construct a new angle with the same measure using geometric constructions.

In contrast, duplicating a line segment refers to creating an exact copy of a given line segment. This can be achieved by using a ruler or other measuring tools to measure the length of the segment and then transferring that length to a different location. The resulting line segment will have the same length as the original.

In summary, duplicating an angle involves reproducing an angle with the same measure, while duplicating a line segment entails creating an identical copy of a given line segment in terms of its length. The methods and tools used for these operations differ, as duplicating an angle relies on geometric constructions, while duplicating a line segment involves measurement and replication techniques.

Answers

The shape of the cross section of the cone that contains the vertex of the cone and diameter of the base is a right triangle.

In a cone, the cross section that contains the vertex and diameter of the base can be visualized as a triangle. Since the height of the cone is greater than the diameter of the base, the vertex of the cone lies above the center of the base. This creates a right triangle when the cross section is observed.

To understand why the cross section is a right triangle, consider a vertical plane passing through the cone's vertex and the center of the base. This plane divides the cone into two parts: a right circular cone and a frustum. The intersection of the plane with the right circular cone creates a triangle. Since the vertex is directly above the center of the base, the triangle's base is a diameter of the base, forming a right angle between the base and the height. Therefore, the shape of the cross section containing the vertex and diameter is a right triangle.

A train leaves sheffield at 1. 48pm and arrives in Londan at 4. 18pm The distance is 170 miles. What was the trains average speed

Answers

the train's average speed was approximately 68 miles per hour.

To calculate the average speed of the train, we need to divide the distance traveled by the time taken.

Given:

Distance: 170 miles

Time taken: 4:18 PM - 1:48 PM = 2 hours and 30 minutes

To calculate the average speed, we first need to convert the time taken to hours. Since there are 60 minutes in an hour, we have:

Time taken = 2 hours + 30 minutes / 60 = 2.5 hours

Now we can calculate the average speed:

Average speed = Distance / Time taken

Answers

After 5 years, the population is expected to double if the growth pattern continues.

To determine after how many years the population will double, we need to consider the growth rate and the initial population.

If the population is increasing every year, it indicates exponential growth. In this case, we can use the formula for exponential growth:

P(t) = P(0) * (1 + r)^t

Where:

P(t) is the population at time t,

P(0) is the initial population,

r is the growth rate per year, and

t is the number of years.

In this scenario, we know that the initial population (P(0)) is 1200. We want to find the value of t when the population (P(t)) doubles, which means it will be 2 * P(0).

2 * P(0) = P(0) * (1 + r)^t

Dividing both sides by P(0):

2 = (1 + r)^t

Now, let's check the given options to determine which one satisfies the equation:

01: (1 + r)^1 = 2 (Not satisfied)

02: (1 + r)^2 = 2 (Not satisfied)

Explain why public opinion polls use sample sizes of more than 1000 people instead of using a smaller sample size.

Answers

Public opinion polls use sample sizes of more than 1000 people because it helps to ensure that the results are statistically significant. This means that the results are likely to be accurate and representative of the population as a whole.

The margin of error for a poll is the amount by which the results of the poll could be off from the actual results. The margin of error is calculated using the sample size, the confidence level, and the standard deviation of the population.

The confidence level is the probability that the results of the poll are within the margin of error. The standard deviation of the population is a measure of how spread out the opinions of the population are.

The larger the sample size, the smaller the margin of error will be. This is because the larger the sample size, the more likely it is that the sample will be representative of the population as a whole.

For example, if a poll has a sample size of 1000 people and a confidence level of 95%, the margin of error will be +/- 3%. This means that there is a 95% chance that the results of the poll are within 3% of the actual results.

If a poll has a sample size of 500 people and a confidence level of 95%, the margin of error will be +/- 4.4%. This means that there is a 95% chance that the results of the poll are within 4.4% of the actual results.

As you can see, the larger the sample size, the smaller the margin of error will be. This is why public opinion polls use sample sizes of more than 1000 people. It helps to ensure that the results are statistically significant and that they are likely to be accurate and representative of the population as a whole.

To represent how much more Company X charges than Company Y for n minutes, we can subtract the total cost of Company Y from the total cost of Company X. The expression that represents this is (35 + 5n) - (20 + 4n) cents. Simplifying this expression yields 15 + n cents.

To find how much more Company X charges than Company Y for n minutes, we need to calculate the difference in their total costs. For Company X, it costs 35 cents to connect and an additional 5 cents for each minute, resulting in a total cost of (35 + 5n) cents for n minutes. For Company Y, it costs 20 cents to connect and an additional 4 cents for each minute, giving a total cost of (20 + 4n) cents for n minutes.

To find the difference, we subtract the total cost of Company Y from the total cost of Company X: (35 + 5n) - (20 + 4n) cents. Simplifying this expression, we combine like terms and get 15 + n cents.

In three years time a pet mouse will be as old as his owner was four years ago. Their present ages total 13 years. Find the age of each now.
please include step by step explanation and thank you ! ​

Answers

The present age of the pet mouse is 3 years, and the present age of the owner is 10 years.

Age of pet mouse and owner in three years will be the same as the owner's age four years ago. Find their present ages.

Let's assign variables to represent the present ages of the pet mouse and the owner. We'll use "M" for the mouse's age and "O" for the owner's age.

According to the problem, in three years' time, the pet mouse will be as old as the owner was four years ago. This can be expressed as:

M + 3 = O - 4

Their present ages total 13 years, so we can write another equation:

M + O = 13

Now we have a system of two equations with two variables. We can solve it using substitution or elimination.

Let's solve it by substitution:

From the first equation, we can isolate M:

M = O - 7

Substituting this value of M into the second equation:

(O - 7) + O = 13

2O - 7 = 13

Adding 7 to both sides:

2O = 20

Dividing both sides by 2:

O = 10

Now that we know the owner's age is 10, we can substitute this value back into one of the original equations to find the mouse's age:

M + 10 = 13

M = 3

Therefore, the present age of the pet mouse is 3 years, and the present age of the owner is 10 years.

Let's assume the smaller number is x. According to the problem, the second number is 1 more than the first, so the larger number can be represented as x + 1.

The problem states that the square of one number (x²) is 23 less than the square of the second number. Mathematically, this can be represented as:

(x + 1)² = x² - 23

Expanding the left side of the equation:

x² + 2x + 1 = x² - 23

Next, we can simplify the equation by canceling out the common terms:

2x + 1 = -23

Solving for x, we subtract 1 from both sides:

2x = -24

Dividing by 2:

x = -12

Therefore, the smaller number is -12, and the larger number is -12 + 1, which is -11.

A proportional relationship exist between x and y. When x = 16 the value of y is 28. Write an equation for v in terms of x.

Answers

The equation describing the proportional relationship between x and y is y = (7/4)x.

In a proportional relationship, the ratio between the two variables remains constant. To find the equation for y in terms of x, we can determine the ratio between the corresponding values of x and y. Given that when x = 16, y = 28, we divide y by x to find the ratio:

y/x = 28/16 = 7/4.

This ratio represents the constant proportionality between x and y. Therefore, the equation for y in terms of x is y = (7/4)x. This equation indicates that y is directly proportional to x, and for every unit increase in x, y increases by 7/4 units. Likewise, for every unit decrease in x, y decreases by 7/4 units. This equation can be used to determine the value of y for any given value of x in the proportional relationship.

Two linear functions are shown below. Which function has the greater range of change?

Answers

IIf the two linear functions are given, we can find their slopes and determine which one has the greater slope (m-value). That function will have the greater range of change. Without the functions, it is not possible to determine which function has the greater range of change.

The two linear functions are not shown below, please provide them or a detailed description of them to determine the function that has the greater range of change.

Let's recall the definition of linear functions. A linear function is a function whose graph is a straight line. Linear functions are known to have a constant rate of change. When written in the slope-intercept form, the equation of a linear function appears as

y = mx + b,

where m represents the slope of the line and b represents the y-intercept. This equation can also be written as

f(x) = mx + b.

Linear functions have a set of specific features that make them easy to analyze and graph, such as domain and range. The domain is the set of all possible x-values, while the range is the set of all possible y-values for a function. Because linear functions are straight lines, they have an infinite domain and range unless there is some other restriction present in the problem statement.The function that has the greater range of change is the one with the greater slope (m-value). This is because the slope determines how fast or slow the line is rising or falling, and thus how much the y-value changes for each unit increase in the x-value. The greater the slope, the greater the change in y for a given change in x.

Therefore, if the two linear functions are given, we can find their slopes and determine which one has the greater slope (m-value). That function will have the greater range of change. Without the functions, it is not possible to determine which function has the greater range of change.

Write the phrase as an algebraic expression one third of Danielle's height​

Answers

The algebraic expression for "one third of Danielle's height" is (1/3)h, where h represents Danielle's height.

In algebraic expressions, variables are used to represent unknown quantities. In this case, we are given the phrase "one third of Danielle's height," which means we need to find an expression that represents a third of Danielle's height. Let's use the variable h to represent Danielle's height.

To express "one third of Danielle's height" algebraically, we can multiply the fraction 1/3 by the variable h. This results in the expression (1/3)h, where (1/3) represents one third and h represents Danielle's height. The expression (1/3)h indicates that we are taking a fraction of h, specifically one third of h.

By using this algebraic expression, we can easily calculate one third of Danielle's height by substituting the value of h into the expression. For example, if Danielle's height is 150 centimeters, we can substitute h = 150 into the expression (1/3)h and evaluate it as (1/3) * 150 = 50 centimeters. Therefore, the expression (1/3)h provides a concise and flexible way to represent one third of Danielle's height in algebraic terms.

Aki is building a ramp at a doorway to her house. The end of the ramp is


6 inches above the ground. The length of the ramp is 6 feet. What is the measure


of the angle formed by the ground and the ramp?

Answers

By evaluating this expression, we find that the measure of the angle formed by the ground and the ramp is approximately 4.76 degrees.

The measure of the angle formed by the ground and the ramp can be determined using trigonometry. In this case, Aki is building a ramp with an end that is 6 inches above the ground and a length of 6 feet. To find the angle, we can use the tangent function, which relates the opposite side (6 inches) to the adjacent side (6 feet).

Using the tangent function, we can calculate the angle as: angle = arctan(opposite/adjacent) = arctan(6 inches / 6 feet)

Before calculating the value, it's important to convert the units to ensure consistency. Converting 6 feet to inches, we have 6 feet * 12 inches/foot = 72 inches.

Plugging the values into the arctan function, we get:

angle = arctan(6 inches / 72 inches)

Erin packed a backpack for a camping trip. The instructions on Erin’s backpack say the backpack must weigh less than 25 pounds when packed. Erin will be packing a 5-pound cooking kit and other supplies. Which inequality best describes w, the weight in pounds of Erin’s backpack after she packs it?

Answers

The inequality that best describes w, the weight in pounds of Erin’s backpack after she packs it is w + 5 < 25. Explanation:

Let's assume the weight of Erin’s backpack as w and the weight of the cooking kit as 5 pounds.

The backpack must weigh less than 25 pounds when packed.

So, the inequality can be written as:w + 5 < 25 (as the cooking kit weighs 5 pounds)Subtracting 5 from both sides,w < 20So, the weight of Erin's backpack should be less than 20 pounds,

otherwise it will exceed the limit of 25 pounds.

Therefore, the inequality that best describes w, the weight in pounds of Erin’s backpack after she packs it is w + 5 < 25.

Therefore, the weight of Erin's backpack should be less than 20 pounds to ensure it does not exceed the limit of 25 pounds.

WHAT IS THE QUOTIENT WHEN YOU DIVIDE THE LCM OF 8, 12 AND 3 BY THEIR HCF

Answers

The quotient obtained when dividing the least common multiple (LCM) of 8, 12, and 3 by their highest common factor (HCF) is 6.

To find the LCM of 8, 12, and 3, we first determine their prime factorizations:

- 8 can be expressed as [tex]2^3[/tex].

- 12 can be expressed as [tex]2^2 * 3^1[/tex].

- 3 is already a prime number.

To calculate the LCM, we consider the highest power of each prime factor that appears in any of the numbers. In this case, we have:

- [tex]2^3 * 3^1[/tex], as the highest powers of 2 and 3.

Multiplying these prime factors together, we get [tex]2^3 * 3^1 = 8 * 3 = 24[/tex].

Next, we find the HCF of the three numbers. The HCF is the highest power of each prime factor that is common to all the numbers. In this case, we have:

- The highest power of 2 is [tex]2^2[/tex].

- The highest power of 3 is [tex]3^0[/tex] (as it is not a factor of 8).

Multiplying these prime factors together, we get [tex]2^2 * 3^0 = 4 * 1 = 4[/tex].

Finally, we divide the LCM by the HCF to find the quotient: 24 / 4 = 6.

Therefore, the quotient obtained when dividing the LCM of 8, 12, and 3 by their HCF is 6.
