Final answer:

After receiving $38,000 and investing it at a 6.0 percent interest rate per year for 10 years, the student will have approximately $68,052.19 in 12 years.

Explanation:

To find out how much the student will have in 12 years after receiving $38,000 and investing it for 10 years at a 6.0 percent interest rate per year, we need to calculate the future value of the investment using the formula for compound interest.

The formula for the future value FV of an investment over time is given by:

FV = PV * (1 + r)^n

Where:

PV = Present Value of the investment (the initial amount of money)

r = annual interest rate (expressed as a decimal)

n = number of years the money is invested

In this case:

PV = $38,000

r = 0.06 (which is 6.0 percent expressed as a decimal)

n = 10

Plugging these values into the formula, we get:

FV = $38,000 * (1 + 0.06)^10

FV = $38,000 * (1.06)^10

FV = $38,000 * 1.790847

FV = $68,052.186

Therefore, the student will have approximately $68,052.19 in 12 years.

The intersection of two planes can be found by solving the system of equations formed by the equations of the planes. In this case, the intersection is given by the equations x = (4 - 9y) / 6, y = y, and z = -3 - (23y/6), where y can be any real number.

The intersection of two planes can be found by solving the system of equations formed by the equations of the planes.

To find the intersection, we can set the two equations equal to each other and solve for x, y, and z.

Therefore, the intersection of the two planes is given by the equations x = (4 - 9y) / 6, y = y, and z = -3 - (23y/6), where y can be any real number.

In this experiment, the type of nail polish represents B. the explanatory variable.

The nail polish brands—Bella, Primrose, Shine, and Glo—are the explanatory variables in the experiment that is being discussed. These are the many conditions or treatments that are being investigated to find out how they affect a certain result.

The primary aim of the experiment is to compare how each type of nail polish performs or is perceived, which requires manipulating the nail polish type and observing the results.

The response variable (or dependent variable) is the outcome that is measured in response to the explanatory variables. This could be factors like durability, appearance, user satisfaction, or any other measurable characteristic related to the nail polish.

Thus, the nail polish brands are the explanatory variables because they are the categories being compared. The response variable would be whatever metric is used to evaluate the performance or characteristics of these nail polishes.

The potential dimensions that could represent the original photograph and its enlargements, with the length being 1 2/5 times the width, are 5 by 7 inches for the original photograph, and 20 by 28 inches and 10 by 14 inches for the enlargements.

To find the dimensions of Sally's original photograph and the enlargements with the area having the given ratio of length to width as 1 2/5, we need to understand the relationship between the area of two similar objects and their linear dimensions. We are given that the original photograph has an area of 35 square inches, and the enlargements have areas of 140 and 560 square inches. With the length being 1 2/5 times the width in each case, we can work out the possible dimensions for these photographs.

Now, let's consider the list of dimensions provided and determine which ones correspond to an area ratio that matches the original photograph or the enlargements:

Conclusively, only some of the dimensions given match the requirements: 5 inches by 7 inches for the original photograph, 20 inches by 28 inches and 10 inches by 14 inches for the enlargements. They adhere to the concept that the ratio of their areas equals the ratio of the squares of their linear dimensions due to scaling.

Answer:

The guinea pig is 210 mm longer than Naomi's fish

or

The guinea pig is 21 cm longer than Naomi's fish

Step-by-step explanation:

Remember that

1 cm=10 mm

Convert cm to mm

guinea pig ------> 25 cm=25*10=250 mm

Subtract the length of Naomi's fish from the length of her guinea pig

so

250-40=210 mm

Convert to cm

210 mm=210/10=21 cm

It depends on the number. Generally, it is false, expect in a few certain cases, such as 2 for example, as:

2 + 2 = 4

2 x 2 = 4

however, most other numbers do not work, such as, for example, 5

5 + 5 = 10

5 x 5 = 25

So it really depends on what "x" is.

Final answer:

The product of (g-7)(g-2) is found by applying the Distributive Property, which results in g² - 9g + 14.

Explanation:

To use the Distributive Property to find the product (g−7)(g−2), we need to multiply each term in the first parenthesis by each term in the second parenthesis. This gives us:

g × g = g²

g × (−2) = − 2g

(−7) × g = − 7g

(−7) × (−2) = 14

Combining these we get g² - 2g - 7g + 14. Simplifying by combining like terms, we obtain:

g² - 9g + 14

Therefore, the product (g−7)(g−2) using the Distributive Property is g² - 9g + 14.

Answer with explanation:

Outlier, in a data set are those real numbers called variates , if we consider two consecutive real numbers in that data set, when data is arranged in ascending or descending order the difference looks filthy,or ambiguous.

For, example , 13,45,  23.45, 35.45, 49.45,55.45, 80.45.

So, we can say that ,applying the above definition , 80.45 is an outlier.

Outliers affect the mean and Standard deviation.

→If you discard 50 % of the data , to get the better result in an experiment,the data set will become smaller and getting accurate result will be a task similar to catch a  ruffian who is riding in a four wheeler and you are running behind him on footsteps.

→Similarly, Examining a smaller random sample of the population will not give accurate result.

Most of the Outliers lie either on right or left of Data set when arranged in ascending or descending order.

To overcome the effect of an outlier,we should consider large sample to get better result, as leaving some variates from right or left will have little effect on the result.

Option B: Examine a larger random sample of the population.

C. There is one outlier that indicates an unusually large number of cars were in the parking lot that day.

To find out how many years until Tevin's age is 5 times Katherine's age, we set up an equation and solve for x, finding that it will take 13 years.

The question is asking us to find out how many years until Tevin's age is 5 times Katherine's age. Let's denote the number of years until this happens as 'x'.

Currently, Tevin is 202 and Katherine is 30.

In x years, Tevin will be 202 + x years old and Catherine will be 30 + x.

Therefore, we want to find x such that:

202 + x = 5(30 + x)

This can be solved as follows:

202 + x = 150 + 5x

Now, we subtract 5x from both sides:

202 - 4x = 150

Subtract 202 from both sides:

-4x = -52

Divide by -4:

x = 13

Therefore, it will take 13 years for Tevin's age to be 5 times Katherine's age.

The required down payment for a condominium priced at $102,000, with a 5% down payment, is $5,100. This is calculated by multiplying the price of the condominium by 0.05. Therefore, the down payment amount is $5,100.

The price of the condominium is $102,000, and the bank requires a 5% down payment. To find the required down payment, we need to calculate 5% of the condominium's price.

Step-by-step solution:

Therefore, the required down payment for the condominium is $5,100.

The length of the longest side of the rectangular prism is approximately

10 centimeters.

The correct option is D.

In three-dimensional space, a prism is a polyhedron where two ends are similar.

To solve the equation 2x³ + 14x² +12x =400, we first need to rearrange it to the standard form of a cubic equation:

2x³ + 14x² +12x - 400 = 0

We can use a graphing calculator to find the real solutions of this equation, which are approximately x = -8.75, x = 2.16, and x = 5.59.

Since the dimensions of the rectangular prism are x + 1, 2x, and x + 6, we need to find the maximum value of the expression (x + 1)(2x)(x + 6) over the interval [2.16, 5.59]. We can set up a system of inequalities to find this maximum value:

2.16 ≤ x ≤ 5.59

(x + 1)(2x)(x + 6) ≥ 400

Using a graphing calculator, we can graph the function f(x) = (x + 1)(2x)(x + 6) and find the maximum value over the interval [2.16, 5.59]. The maximum value occurs at x ≈ 4.98, and the value of the function at this point is approximately 469.83.

Therefore, the length of the longest side of the rectangular prism is approximately 4.98 + 6 = 10.98 centimeters, which is closest to answer choice D) 10 centimeters.

The slant height of a cone with a radius of 7 meters and a surface area of 395.64 square meters is approximately 11 meters, which corresponds to option C.

To find the slant height of a cone when you know the radius (r) and the surface area, you can use the formula for the surface area of a cone, which is spelled out as A = πrs + πr², where A is the surface area, r is the radius, and s is the slant height. In this case, you know that the surface area (A) is 395.64 square meters and the radius (r) is 7 meters. So, you can rearrange the formula to solve for the slant height(s) : A - πr² = πrs => (A - πr²)/πr = s.

Insert the values into the formula: s = (395.64 - 3.14*7²) / (3.14*7). By performing these calculations, you'll find that the slant height is approximately equal to 11, which corresponds to option C.
