What is the slant height if the surface area is 395.64 square meters? (Use 3.14 for π .) r = 7 of a cone
A. 7
B. 9
C. 11
D. 13
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.
Explanation: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.

Use the intercepts to graph the equation 8x - 5y = 40
To graph the equation 8x - 5y = 40, find the x-intercept and y-intercept. The x-intercept is (5,0) and the y-intercept is (0,-8). Plot these points and draw a straight line passing through them.
Explanation:To graph the equation 8x - 5y = 40 using intercepts, we need to find the x-intercept and y-intercept. The x-intercept is the point where the line intersects the x-axis, so let y = 0 and solve for x. The y-intercept is the point where the line intersects the y-axis, so let x = 0 and solve for y.
Setting y = 0, we get 8x - 5(0) = 40, which simplifies to 8x = 40. Solving for x, we find x = 5. So the x-intercept is (5, 0).
Setting x = 0, we get 8(0) - 5y = 40, which simplifies to -5y = 40. Solving for y, we find y = -8. So the y-intercept is (0, -8).
Plotting the x-intercept (5, 0) and the y-intercept (0, -8) on a graph, we can draw a straight line passing through these two points, which is the graph of the equation 8x - 5y = 40.

You are scheduled to receive $38,000 in two yeara. when you receive it, you will invest it for 10 more years at 6.0 percent per yeat. how much will you have in 12 years?
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.

Factor 6y 2 - 48 + 42y
The expression 6y² - 48 + 42y is factored by first rearranging the terms, finding the GCF, and then factoring the resulting trinomial to get 6(y + 8)(y - 1).
To factor the expression 6y² - 48 + 42y, the first step is to rearrange the terms in descending powers of y, which gives us 6y² + 42y - 48. Next, we can look for a greatest common factor (GCF) among the three terms. Observing that each term is divisible by 6, we can factor out 6:
6(y² + 7y - 8)
Now, we need to factor the trinomial within the parentheses. We are looking for two numbers that multiply to give -8 (coefficient of y² times constant term), and add to 7 (coefficient of y term). The numbers +8 and -1 satisfy these conditions:
6(y + 8)(y - 1)
Thus, the original expression 6y² - 48 + 42y factors to 6(y + 8)(y - 1).

What is the volume of a rectangular prism with length 7 cm, height 6 cm, and width 13 cm? V = l x w x h
Use the Distributive Property to find (g−7)(g−2).
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.
tevin is 202 years old Catherine is 30 years old how many years until Tevin age is 5 * Katherine's age
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.

A rectangular prism with a volume of 400 cubic centimeters has the dimensions x + 1 centimeters, 2x centimeters, and x + 6 centimeters. The equation 2x^3 + 14x^2 +12x =400 can be used to find x. What is the length of the longest side? Use a graphing calculator and a system of equations to find the answer.
A) 4 centimeters
B)5 centimeters
C)8 centimeters
D)10 centimeters
The length of the longest side of the rectangular prism is approximately
10 centimeters.
The correct option is D.
What is a prism?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.

How can the effect of an outlier be overcome in an experiment that examines a random sample of a population? A) Discard 50% of the data. B) Examine a larger random sample of the population. C) Examine a smaller random sample of the population. D) There is no way to overcome the effect of an outlier.
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.
