The formula for the n-th term of a geometric sequence is a = arn−1where a is the first term, r is the common ratio, and n is the number of terms.
In the given sequence, a1 = 18, and a n = 2 a n−1 , which is a geometric sequence with common ratio r = 2.
The explicit formula of the sequence is a(n) = a1 x r^(n - 1) where a1 = 18 and r = 2.Using the explicit formula,a(19) = 18 x 2^(19-1) = 18 x 2^18 = 150994944a(20) = 18 x 2^(20-1) = 18 x 2^19 = 301989888
Given a geometric sequence a n =2a n-1 with an initial value of a 1 = 18. Let's find the explicit formula of the sequence.The formula for the n-th term of a geometric sequence is given as:
a = arn−1 Where a is the first term, r is the common ratio, and n is the number of terms. Here, a1 = 18, and a n = 2 a n−1.
Hence the common ratio r is 2.To find the explicit formula for this sequence, we substitute a1 and r in the above formula. Hence the explicit formula for this sequence is given as:
a(n) = a1 x r^(n - 1)where a1 = 18 and r = 2.Let's find the 19th and 20th term in the sequence using this explicit formula.
Substituting n = 19 in the explicit formula, we get,a(19) = 18 x 2^(19 - 1)= 18 x 2^18= 150994944
Substituting n = 20 in the explicit formula, we get,a(20) = 18 x 2^(20 - 1)= 18 x 2^19= 301989888Hence the 19th term in the sequence is 150994944 and the 20th term in the sequence is 301989888
The explicit formula of the sequence is a(n) = a1 x r^(n - 1) where a1 = 18 and r = 2.Using this formula, we have found that the 19th term in the sequence is 150994944 and the 20th term in the sequence is 301989888.

what is the answer?
The ratio of the time taken by Brian and Colin to mark exam papers is 43 minutes to 1 hour. Hence, the simplified ratio of the time taken by Brian and Colin to mark exam papers is 43:60.
To express the times taken by Brian and Colin as a ratio, we need to convert their times to a common unit. Since both Brian and Colin's times are given in minutes and hours respectively, we need to convert Colin's time to minutes.
We know that 1 hour is equal to 60 minutes. Therefore, Colin's time of 1 hour can be expressed as 60 minutes.
Now, the ratio of Brian's time to Colin's time is 43 minutes to 60 minutes. However, we can simplify this ratio by dividing both numbers by their greatest common divisor, which is 1.
Dividing 43 and 60 by 1 gives us the simplified ratio of 43:60. This ratio cannot be further simplified since there is no common factor greater than 1 between 43 and 60.
Hence, the simplified ratio of the time taken by Brian and Colin to mark exam papers is 43:60.

WILL GIVE BRAINLIST PLEASE HELP!
The volume of the square pyramid is 1568 cubic inches. Given that the pyramid has a perimeter of 56 inches, we can determine the length of each side of the square base.
To find the volume of a square pyramid, we need to know the length of the base and the height of the pyramid.
Since a square has all sides equal in length, we divide the perimeter by 4 (the number of sides) to find the length of each side:
Length of each side = 56 inches / 4 = 14 inches
Now, we need to find the height of the pyramid. The slant height given is the distance from the apex of the pyramid to the midpoint of one of the sides. To find the height, we need to use the Pythagorean theorem.
The slant height represents the hypotenuse of a right triangle, with one leg being half the length of the base side and the other leg being the height. Let's call the half of the base length "a" and the height "h."
Using the Pythagorean theorem, we have:
a^2 + h^2 = slant height^2
Since the base side is half the length of the perimeter, we have:
a = 14 inches / 2 = 7 inches
Plugging in the values, we get:
7^2 + h^2 = 25^2
49 + h^2 = 625
h^2 = 625 - 49
h^2 = 576
h = √576
h = 24 inches
Now that we have the length of the base (14 inches) and the height (24 inches), we can calculate the volume of the pyramid using the formula:
Volume = (1/3) * base area * height
The base area of a square is given by side length squared:
Base area = (14 inches)^2 = 196 square inches
Plugging in the values, we have:
Volume = (1/3) * 196 square inches * 24 inches
Volume = (1/3) * 4704 cubic inches
Volume = 1568 cubic inches

Write a function rule to represent the situation.
the total cost C for g grams of ham if each gram costs $5.77
Write a function rule using C and g as variables.
(Type an equation.)
The function rule representing the situation is C = 5.77g, where C is the total cost and g is the weight of ham in grams.
The function rule C = 5.77g represents the relationship between the total cost (C) and the weight of ham (g) in grams. In this situation, each gram of ham costs $5.77, so the total cost is obtained by multiplying the cost per gram ($5.77) by the weight of ham (g).
The equation C = 5.77g follows a linear relationship, where the cost (C) is directly proportional to the weight of ham (g). This means that as the weight of ham increases, the total cost also increases proportionally. For example, if we have 100 grams of ham, the total cost would be calculated as 5.77 * 100 = $577.
By using this function rule, we can easily determine the total cost of any given weight of ham. It provides a straightforward way to calculate the cost without needing to perform complex calculations or look up individual prices for different quantities. This equation can be useful in various situations, such as meal planning, budgeting, or determining the cost for commercial purposes.

Suppose you invest $850 in a certificate of deposit that is promised to make you 1% interest if you keep the money in the account for 16 months. How much money should be in the account after the 16 months has elapsed?
After 16 months, the amount of money in the account should be approximately $861.33.
To calculate the total amount in the account after 16 months with a 1% interest rate, we need to apply the formula for compound interest: A = P(1 + r)^t, where A is the final amount, P is the principal amount, r is the interest rate, and t is the time period.
In this case, you invest $850 as the principal amount with an interest rate of 1% (or 0.01 as a decimal). The money will be kept in the account for 16 months, so t = 16/12 = 4/3 years (since there are 12 months in a year).
Substituting the given values into the compound interest formula, we have:
A = $850(1 + 0.01)^(4/3)
Simplifying the exponent:
A = $850(1.01)^(4/3)
Evaluating the exponent:
A = $850(1.01005)
Multiplying:
A ≈ $861.33
after 16 months, the amount of money in the account should be approximately $861.33.

The height of a toy rocket launched from a 64- foot observation tower as a function of elapsed time since the launch is modeled by the equation shown below h(t) =-16t
The height (h) of a toy rocket launched from a 64-foot observation tower as a function of elapsed time (t) is given by the equation h(t) = -16t.
The equation h(t) = -16t represents a mathematical model that relates the height of the toy rocket (h) to the elapsed time since the launch (t). In this model, the rocket's height decreases at a constant rate of 16 feet per second. The negative sign indicates that the rocket is descending rather than ascending.
Since the initial height of the toy rocket is 64 feet (from the observation tower), we can determine the height of the rocket at any given time by substituting the value of t into the equation. For example, if we want to find the rocket's height after 3 seconds, we substitute t = 3 into the equation: h(3) = -16 * 3 = -48 feet. This means that after 3 seconds, the toy rocket is 48 feet below the observation tower. Similarly, we can calculate the height at any other time by substituting the corresponding value of t into the equation.

What property allows one to set aside the order of operations how
The property that allows one to set aside the order of operations is called the Commutative Property. The order of operations is also known as the PEMDAS rule.
The order of operations, also known as the PEMDAS rule (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), is a fundamental principle in mathematics that dictates the sequence in which operations should be performed in an arithmetic expression. However, there are instances where the order of operations can be set aside or rearranged without affecting the final result. This is possible due to the Commutative Property, which applies to addition and multiplication.
The Commutative Property states that the order in which numbers are added or multiplied does not change the result. For addition, it means that the sum of two numbers remains the same regardless of the order in which they are added.
By applying the Commutative Property, one can rearrange the order of addition or multiplication operations, allowing for more flexibility in evaluating expressions. This property is particularly useful when simplifying or solving mathematical equations, as it enables us to change the order of terms without altering the final outcome. However, it's important to note that the Commutative Property does not apply to subtraction or division operations, and the order of operations should be followed strictly in such cases.

Solve. 2. 5m 24 = 62 m = 1. 52 m = 15. 2 m = 34. 4 I don't know.
The equation is satisfied, confirming that m = 15.2 is the correct solution.
To solve the equation 2.5m + 24 = 62, we need to isolate the variable m.
First, let's subtract 24 from both sides of the equation:
2.5m + 24 - 24 = 62 - 24
This simplifies to:
2.5m = 38
To isolate m, we divide both sides of the equation by 2.5:
(2.5m) / 2.5 = 38 / 2.5
This gives us:
m = 15.2
Therefore, the solution to the equation 2.5m + 24 = 62 is m = 15.2.
In the given options:
m = 1.52 is not the solution since it doesn't satisfy the equation.
m = 15.2 is the correct solution, as we obtained above.
m = 34.4 is not the solution since it also doesn't satisfy the equation.
So, the correct answer is m = 15.2.
It's important to check our solution by substituting the value of m back into the original equation:
2.5(15.2) + 24 = 62
38 + 24 = 62
62 = 62
The equation is satisfied, confirming that m = 15.2 is the correct solution.

A guy wire is attached to an antenna tower that is perpendicular to the ground. The wire is attached 100 feet up the tower and makes an angle of 55 degrees with the ground. What is the length of the wire?
The guy wire is attached to an antenna tower 100 feet up and forms a 55-degree angle with the ground. We need to determine the length of the wire.
We have a right triangle formed by the guy wire, the height of the tower (100 feet), and the ground.
Let's denote the length of the guy wire as "w."
Using trigonometric ratios, we can use the sine function to relate the angle and the sides of the right triangle:
sin(angle) = opposite/hypotenuse
In this case, the opposite side is the height of the tower (100 feet), and the hypotenuse is the length of the guy wire (w).
sin(55 degrees) = 100/w
To solve for w, we can rearrange the equation:
w = 100/sin(55 degrees)
Using a calculator, we can calculate the value of sin(55 degrees) ≈ 0.8192.
Substituting this value into the equation, we have:
w ≈ 100/0.8192 ≈ 122.16
Therefore, the length of the guy wire is approximately 122.16 feet.

One triangle has a base of 6 inches and the other is 10 inches. The total area of the two triangles is _____ square inches. Numerical Answers Expected! Answer for Blank 1:.
To find the total area of the two triangles, we need to calculate the area of each triangle and then add them together.
The formula for the area of a triangle is given by:
Area = (base * height) / 2
For the first triangle:
Base = 6 inches
Height = 8 inches
Area of the first triangle = (6 * 8) / 2 = 48 / 2 = 24 square inches
For the second triangle:
Base = 10 inches
Height = 8 inches
Area of the second triangle = (10 * 8) / 2 = 80 / 2 = 40 square inches
Now, we can find the total area of the two triangles by adding their individual areas together:
Total area = Area of the first triangle + Area of the second triangle
Total area = 24 square inches + 40 square inches = 64 square inches
Therefore, the total area of the two triangles is 64 square inches.

The mean distance that Principal Phillipi's students live from the school, rounded to the nearest tenth is 4.2 miles. So correct option is B.
The term "mean" has multiple interpretations, but in the context of statistics, it commonly refers to the arithmetic mean. The arithmetic mean is a measure of central tendency that represents the average value of a set of numbers.
To calculate the arithmetic mean, you sum up all the values in a data set and divide the sum by the total number of values. The formula for calculating the mean is:
Mean = (sum of all values) / (total number of values)
The arithmetic mean is widely used in statistics and data analysis as a measure to describe the central tendency of a data set. It provides a representative value that summarizes the overall behavior of the data. However, it is important to note that the mean can be influenced by extreme values, and it may not accurately represent the entire data set in certain cases.
How to find the mean distance of students who live from the school?
The mean is defined as the sum of all the terms divided by the number of terms.
The formula to find the mean is:
Mean = Sum of values/Total number of values
In this case, the given values are 3, 4, 5, 3, 4, 5, 6, 5, 4, 3, 2, 3, 4, 5, 6, 4, 8, 4, 3, 2

a circle of diameter 60cm is cut out of a square of a side 80cm,
calculate the shaded area
The shaded area can be calculated by subtracting the area of the circle from the area of the square. So the shaded area is approximately is 3574 cm².
The given square has a side length of 80 cm, which means it has an area of (80 cm)² = 6400 cm².
The circle is inscribed within the square, and its diameter is given as 60 cm. The radius of the circle is half the diameter, so the radius is 60 cm / 2 = 30 cm. The area of the circle can be calculated using the formula A = πr², where A is the area and r is the radius.
Substituting the values, the area of the circle is A = π(30 cm)² = 900π cm².
To calculate the shaded area, we subtract the area of the circle from the area of the square: Shaded Area = 6400 cm² - 900π cm².
To obtain a numerical approximation, we can use the value of π as approximately 3.14: Shaded Area ≈ 6400 cm² - 900(3.14) cm².
Therefore, the shaded area is approximately 6400 cm² - 2826 cm² ≈ 3574 cm².

Tim uses 9 liters of water (w) to water 24 flower pots (f). If this relationship is proportional, what equation represents this relationship? *
The relationship between the amount of water (w) and the number of flower pots (f) is proportional.
In a proportional relationship, the ratio between the two quantities remains constant. In this case, the amount of water used (w) is directly proportional to the number of flower pots (f) that need to be watered. To find the equation that represents this relationship, we can set up a proportion using the given information.
Let's assume that x represents the constant ratio between the amount of water used and the number of flower pots. The equation can be written as:
w/f = x
Substituting the given values, we have:
9/24 = x
Simplifying the equation, we find:
x = 9/24
To find the final equation, we can multiply both sides of the equation by 24:
24x = 9
Therefore, the equation that represents the proportional relationship between the amount of water (w) and the number of flower pots (f) is 24x = 9. This equation shows that for every 24 flower pots, 9 liters of water are required.

The Time Period from 500 A. D. - 1000 A. D. When the economy was falling apart is called.
A. The Early Ages
B. The Roman Ages
C. The Black Ages
D. The Dark Ages
The time period from 500 A.D. to 1000 A.D. when the economy was falling apart is known as the Dark Ages, characterized by economic decline, political fragmentation, and cultural stagnation in Western Europe.
The correct term for the time period from 500 A.D. to 1000 A.D. when the economy was falling apart is "D. The Dark Ages." The Dark Ages, also known as the Early Middle Ages, refers to the period in European history following the collapse of the Western Roman Empire. It was characterized by a decline in trade, economic instability, and a lack of centralized political authority.
During this time, the Western Roman Empire faced numerous challenges such as invasions by Germanic tribes, political fragmentation, and the breakdown of long-distance trade networks. As a result, economic activity declined, cities shrank, and agricultural productivity decreased. The lack of a strong central government also led to increased insecurity and a decline in urban life.
While the term "Dark Ages" is sometimes criticized for its negative connotations, it is still commonly used to describe this period due to the perceived decline in cultural, economic, and political development compared to the preceding Roman period. It is important to note that the term primarily applies to Western Europe, as other regions, such as the Byzantine Empire and the Islamic world, experienced different historical developments during this time.

Find a number written in binary system that when read as a number in decimal system is five times
smaller than the same number read as a decimal (notice that any binary number can be also
interpret as a decimal, for example 111 can represent a binary number but also can be seen as one
hundred and eleven - a decimal).
Treat this question like a puzzle, just try different numbers and this way guess the answer.
Considering, the binary number to be represented is a two-digit number, the binary number to be represented is 0101.
Let us assume that the binary number to be represented is a two-digit number.
Therefore, it can be represented as xy where x and y are either 0 or 1.
We know that any binary number can also be interpreted as a decimal number.
For example, 111 can represent a binary number but also can be seen as one hundred and eleven - a decimal.
The number written in the binary system is thus 2x + y.
The number written in the decimal system is = x × 10 + y, which is 5 times greater than the binary number when the binary number is written in the decimal system.
5(2x + y) = x × 10 + y
10x - 9y = 0
y = 0, 10, 20, 30, ... are some solutions, but y cannot be greater than 10, as it is a two-digit number in the binary system.
As a result, the only feasible solution is y = 0.5(2x)
= 10x
x = 5
Therefore, the binary number to be represented is 0101.
