The statement that must be true when calculating the effective rate of a loan with n = 1 is: III. The interest is compounded annually. Therefore, the answer is d. III only.

When n equals 1, it means that the interest is compounded once per year. In this case, the effective rate of the loan is equal to the nominal rate since there are no additional compounding periods within the year.

This is because when n equals 1, there is no need to consider the length of the loan (statement II) since it is already implied that the loan is for one year.

However, statement I, which states that the nominal rate equals the effective rate, may not necessarily be true for loans with other values of n. Hence, only statement III is required to be true when n equals 1 to calculate the effective rate of a loan.

Let us take the given clues one by one to understand the number.•

The number has seven hundreds.If the number has seven hundreds, it means that it is greater than or equal to 700.• The tens digit has a value of 30.Since the tens digit has a value of 30, the number should be greater than 300 and less than 400.• The ones digit is less than any other digit in the number.If the ones digit is less than any other digit in the number, it means that the ones digit could be either 0, 1, 2, or 3. But since the tens digit has a value of 30, the ones digit cannot be 0.

Therefore, the ones digit is either 1, 2, or 3.So, the possible numbers are:

731, 732, 733.

Since the number has seven hundreds, the only possible number that can be obtained by adding seven hundred to the three-digit numbers above is:

731 + 700 = 1432.

The x-intercepts for the function f(x) = x^2 + 2x - 15 are x = -5 and x = 3.

To find the x-intercepts, we set the function equal to zero and solve for x. In this case, we have the equation:

x^2 + 2x - 15 = 0

To factor this quadratic equation, we look for two numbers that multiply to -15 and add up to 2. The numbers that satisfy this condition are -5 and 3.

Therefore, the factored form of the equation is:

(x - 3)(x + 5) = 0

Setting each factor equal to zero, we find the x-intercepts:

x - 3 = 0 --> x = 3

x + 5 = 0 --> x = -5

Hence, the x-intercepts for the function f(x) = x^2 + 2x - 15 are x = -5 and x = 3.

To find the unknown measures in the similar triangles ▵XYZ ~ ▵PQR, we need to determine the corresponding sides and angles that are proportional.

Corresponding sides:

Corresponding side XY in ▵XYZ corresponds to side PQ in ▵PQR.

Corresponding side XZ in ▵XYZ corresponds to side PR in ▵PQR.

Corresponding side YZ in ▵XYZ corresponds to side QR in ▵PQR.

Corresponding angles:

Angle X in ▵XYZ corresponds to angle P in ▵PQR.

Angle Y in ▵XYZ corresponds to angle Q in ▵PQR.

Angle Z in ▵XYZ corresponds to angle R in ▵PQR.

Based on the similarity of the triangles, we can set up proportions using the corresponding sides or angles. Let's denote the measures of the corresponding sides as follows:

XY = x, PQ = y

XZ = a, PR = b

YZ = c, QR = d

Using the corresponding side lengths, we can write the following proportions:

XY / PQ = XZ / PR = YZ / QR

Substituting the values, we have:

x / y = a / b = c / d

Similarly, using the corresponding angles, we can write the following proportions:

Angle X / Angle P = Angle Y / Angle Q = Angle Z / Angle R

Now, without specific measurements or additional information about the triangle, we cannot determine the exact values of the unknown measures in ▵XYZ and ▵PQR. However, based on the given similarity, we know that the ratios of corresponding sides and corresponding angles are equal.

the function f(x) is greater than or equal to 0 on the intervals [-1, 0) and [2, ∞). Therefore, the solution is option a): [–1, 0) ∪ [2, ∞).

Given the function f(x) = x4 – x3 – 2x2. To determine on which intervals the function f(x) is greater than or equal to 0, we need to find the roots of the equation first. We can find the roots by equating f(x) to 0: x4 – x3 – 2x2 = 0 ⇒ x2(x2 – x – 2) = 0 ⇒ x2(x + 1)(x – 2) = 0

Now, we have three roots for the given equation, which are 0, -1 and 2. We can use these roots to form intervals and check whether the value of the function f(x) is greater than or equal to 0 or not. Now, we will proceed to find the values of the function in different intervals:

On the interval (-∞, -1): Choose x = -2 ⇒ f(-2) = (-2)4 - (-2)3 - 2(-2)2 = 16 + 8 - 8 = 16 ⇒ f(x) is greater than 0 on this intervalOn the interval (-1, 0): Choose x = -0.5 ⇒ f(-0.5) = (-0.5)4 - (-0.5)3 - 2(-0.5)2 = 0.0625 + 0.125 - 0.5 = -0.3125 ⇒  

f(x) is less than 0 on this intervalOn the interval (0, 2): Choose x = 1 ⇒ f(1) = 14 - 13 - 2 = -1 ⇒ f(x) is less than 0 on this intervalOn the interval (2, ∞): Choose x = 3 ⇒ f(3) = 3^4 - 3^3 - 2(3)^2 = 27 ⇒ f(x) is greater than 0 on this Interval Th

therefore, the solution is option a): [–1, 0) ∪ [2, ∞)

We can solve the given question through the method of intervals. For this purpose, we first need to find the roots of the given equation, which are 0, -1 and 2.

After finding the roots, we can divide the real line into different intervals and check whether the value of the function is greater than or equal to 0 or not. We will start by dividing the real line into four intervals, which are (-∞, -1), (-1, 0), (0, 2), and (2, ∞).

For the interval (-∞, -1), we will choose a value that lies between -∞ and -1, let's say x = -2. Now, we will substitute this value of x in the given function to find its corresponding value, which is f(-2) = (-2)4 - (-2)3 - 2(-2)2 = 16 + 8 - 8 = 16.

Since the value of the function f(x) is positive on this interval, we can say that f(x) is greater than or equal to 0 for all x between -∞ and -1.For the interval (-1, 0), we will choose a value that lies between -1 and 0, let's say x = -0.5.

Now, we will substitute this value of x in the given function to find its corresponding value, which is f(-0.5) = (-0.5)4 - (-0.5)3 - 2(-0.5)2 = 0.0625 + 0.125 - 0.5 = -0.3125.

Since the value of the function f(x) is negative on this interval, we can say that f(x) is less than 0 for all x between -1 and 0.For the interval (0, 2), we will choose a value that lies between 0 and 2, let's say x = 1.

Now, we will substitute this value of x in the given function to find its corresponding value, which is f(1) = 14 - 13 - 2 = -1.

Since the value of the function f(x) is negative on this interval, we can say that f(x) is less than 0 for all x between 0 and 2.For the interval (2, ∞), we will choose a value that lies between 2 and ∞, let's say x = 3.

Now, we will substitute this value of x in the given function to find its corresponding value, which is f(3) = 3^4 - 3^3 - 2(3)^2 = 27. Since the value of the function f(x) is positive on this interval, we can say that f(x) is greater than or equal to 0 for all x greater than 2.

Therefore, the solution is option a): [–1, 0) ∪ [2, ∞)

We can solve the given question by finding the roots of the given equation and then dividing the real line into different intervals.

After that, we can check whether the value of the function is greater than or equal to 0 or not on each interval. In this case, we found that the function f(x) is greater than or equal to 0 on the intervals [-1, 0) and [2, ∞). Therefore, the solution is option a): [–1, 0) ∪ [2, ∞).

It takes about 2.28 seconds for the ball to hit the ground. Hence, the answer is option (3) 2.28 seconds.

The function H(t) = -16t² + 73t + 6 represents the height in feet of the baseball thrown by Amir as a function of time t in seconds.

To determine how long it takes for the ball to hit the ground, we need to find the value of t when H(t) = 0 (since the ball is on the ground when its height is zero).

Therefore, we have to solve the quadratic equation:

[tex]$$-16t^2 + 73t + 6 = 0$$[/tex]

We can use the quadratic formula:

[tex]$$t = \frac{-b \pm \sqrt{b^2-4ac}}[/tex]

where a = -16, b = 73, and c = 6.

Substituting the values in the formula, we have:

[tex]$$t = \frac{-73 \pm \sqrt{73^2 - 4(-16)(6)}}$$$$t = \frac{-73 \pm \sqrt{5329 + 384}}$$$$t = (\frac{-73 \pm \sqrt{5713})}[/tex]

Since we're interested in the positive value of t, we take:

Jose works a total of 35 hours per week during the summer, which is 175% more than his regular work hours during the school year.

During the school year, Jose works 20 hours per week. To calculate how many hours he works during the summer, we need to find 175% of his regular work hours.

To calculate 175% of a value, we multiply the value by 1.75. So, 175% of 20 hours is calculated as follows:

175% * 20 hours = (175/100) * 20 hours = 35 hours

Therefore, during the summer, Jose works 35 hours per week. This is an increase of 175% compared to his regular work hours during the school year.

In other words, the 175% increase means that Jose's work hours in the summer are 1.75 times his regular work hours. This can also be calculated as follows:

Regular work hours during the school year + 175% increase = 20 hours + (175/100) * 20 hours = 20 hours + 35 hours = 35 hours

So, Jose works a total of 35 hours per week during the summer, which is 175% more than his regular work hours during the school year.

Answer: Let's assume the high temperature on Monday is represented by C30 (30 degrees Celsius). Since the pool is open when the high temperature is higher than 20 degrees Celsius, the pool was open on Monday.

However, over the next three days, the high temperature decreased at a constant rate. Let's denote the rate of decrease as "r" (in degrees Celsius per day).

Since the high temperature on Monday was C30, we can calculate the high temperature on Thursday by subtracting the decrease in temperature over three days:

High temperature on Thursday = C30 - 3r

We know that the pool was closed on Thursday, so the high temperature on Thursday must have been lower than or equal to 20 degrees Celsius.

Therefore, we can set up the inequality:

C30 - 3r ≤ 20

Now, we can solve this inequality to find the range of values for the rate of decrease (r) that would satisfy the condition:

C30 - 3r ≤ 20

Substituting C30 = 30, we have:

30 - 3r ≤ 20

Subtracting 30 from both sides:

-3r ≤ -10

Dividing by -3 (and reversing the inequality since we are dividing by a negative number):

r ≥ 10/3

Therefore, for the pool to be closed on Thursday, the rate of decrease in temperature (r) must be greater than or equal to 10/3 degrees Celsius per day.

The mistake in the given equation occurs in Step 2. The equation 3x/3 + 3x^2 = 4.5 is incorrectly simplified to 3/4.5 = 1.5.

In Step 1, the equation 3x/3 + 3x^2 = 4.5 is correctly written. However, in Step 2, the mistake happens during the simplification process. The equation is simplified as 3/4.5 = 1.5, which is incorrect.

To identify the mistake, let's analyze Step 2 in detail. The equation 3x/3 + 3x^2 = 4.5 can be simplified by dividing both sides of the equation by 3. This gives us x + x^2 = 4.5/3, which further simplifies to x + x^2 = 1.5.

To solve this equation correctly, we need to rearrange it into the standard quadratic form, which is ax^2 + bx + c = 0. Thus, we obtain x^2 + x - 1.5 = 0. From here, we can either factorize or use the quadratic formula to find the solutions for x.

The exponential value equation is  [tex]f(t) = 2.2e^{(0.009009t)}[/tex]

Given data ,

To convert the given exponential function [tex]f(t) = 2.2(1.009)^t[/tex] to the form [tex]f(t) = Q_{0} e^{kt}[/tex], we need to rewrite it using the base of natural logarithm e.

First, let's rewrite the function by expressing 1.009 as e raised to a certain power:

[tex]f(t) = 2.2 *e^{(ln(1.009)t)}[/tex]

Now, we have the base of e. To find the values of Q0 and k, we need to match the coefficients.

Comparing the functions, we can see that Q0 = 2.2.

To find k, we'll use the property that ln(aᵇ) = b x ln(a). In this case, a = 1.009:

k = ln(1.009)

k ≈ 0.009009.

Hence , the exponential function [tex]f(t) = 2.2(1.009)^t[/tex] can be rewritten in the desired form [tex]f(t) = Q_{0} e^{kt}[/tex], rounded to four significant digits.

Let's start solving the problem by identifying the given information: Leah's house is a mile from school. Josh's house is a mile from school. They both live in the same direction from school and on the same side of Forest Road. To find out how much farther does Leah have to walk home when she reaches Josh's house.

We need to find the distance between Josh's house and the school and then subtract the distance between Leah's house and the school. This will give us the difference, which is the amount farther Leah has to walk. Let's assume the school is located at point A on Forest Road. Leah's house is located a mile away from the school, so it is located at point B.

Josh's house is also located a mile away from the school in the same direction as Leah's house, so it is located at point C. Now, we need to find the distance between point C and point A, which is the distance between Josh's house and the school. Since both Leah's and Josh's houses are equidistant from the school, we know that the distance between point B and point A is also a mile. Therefore, the distance between point C and point A is 2 miles (1 mile from A to B + 1 mile from B to C).Now, we can find the distance Leah has to walk farther by subtracting the distance between point B and point A from the distance between point C and point A:2 miles - 1 mile = 1 mile Therefore, Leah has to walk an additional 1 mile when she reaches Josh's house to get to her own house.

We need to consider that each kitten is fed half as much as a full-grown cat. Let's assume the amount of cat food needed for a full-grown cat is x pounds. In that case, each kitten would require x/2 pounds of cat food.

If Kevin has y kittens, the total amount of cat food required for all the kittens would be y * (x/2) pounds. Since we know that Kevin has 3.51 pounds of cat food available, we can set up the equation:

3.51 = y * (x/2)

To find the number of kittens, we need to know the specific amount of cat food needed for a full-grown cat (x). Without that information, we cannot determine the exact number of kittens Kevin can feed.

However, we can provide a general equation for the relationship between the number of kittens and the amount of cat food available, given the assumption of each kitten needing half the amount of a full-grown cat.

A window in an apartment building is 32 m above the ground. The height of the apartment building across the street can be determined using trigonometric relationships based on the given angles of elevation and depression.

Let's denote the height of the apartment building across the street as h. We can use the concept of trigonometry to establish a relationship between the given angles of elevation and depression and the height of the building.

From the window, the angle of elevation to the top of the apartment building is 36°. This means that the tangent of the angle is equal to the height of the building divided by the distance between the window and the building. Using trigonometric ratios, we have:

tan(36°) = h / x   ---(1)

Similarly, from the same window, the angle of depression to the bottom of the apartment building is 47°. Again, we can use the tangent function to express the relationship:

tan(47°) = h / (x + 32)   ---(2)

By solving equations (1) and (2) simultaneously, we can determine the height of the apartment building across the street, h.

Shape C, a complicated shape, needs to be divided into simpler shapes in order to calculate its area. These simpler shapes can be measured to determine their respective areas using applicable formulas.

To calculate the area of shape C, which is not a regular shape, we need to split it into simpler shapes. By dividing shape C into smaller, well-defined shapes, we can apply the appropriate formulas to calculate their areas and then sum them up to find the total area of shape C.

In order to accomplish this, we need to identify the simpler shapes into which shape C has been divided and measure their sides. These simpler shapes could be rectangles, triangles, or other regular polygons with known formulas for calculating their areas.

Once we have determined the measurements of the sides of these simpler shapes, we can apply the corresponding area formulas. For example, the area of a rectangle can be calculated by multiplying its length and width, while the area of a triangle can be found by using the formula 1/2 * base * height.

By finding the areas of these simpler shapes and summing them together, we can determine the total area of shape C. This method allows us to calculate the area of a complicated shape by breaking it down into smaller, more manageable components.
