What is the surface of a sphere with a radius of 9 units
Answer: 324π units²
Step-by-step explanation:
The formula for the surface area of a sphere is: A=4πr²
Now we just plug in 9 for r:
A = 4π(9)²
A = 4π*81
A = 324π
Answer:
1018 units^2
Step-by-step explanation:
The surface area of a sphere is given by A = 4pi(r)^2, where r is the radius.
Here, A = 4(3.14159)(9 units)^2 = 1018 units^2, to the nearest integer.
How do you find the same y intercept
Answer:
D
Step-by-step explanation:
The y-intercept is the number or constant at the end of the equation.
D sets both of their y-intercepts to -6, so it's correct.
=============================================
Explanation:
Plug x = 0 into f(x)
f(x) = 4x + 1
f(0) = 4(0) + 1
f(0) = 1
The y intercept of f(x) is 1
----------
Now plug x = 0 into g(x)
g(x) = 3^x - 2
g(0) = 3^0 - 2
g(0) = -1
The y intercept of g(x) is -1
----------
Note how the y intercepts are 2 units apart.
Each of the answer choices are in the form of f(x) + M and g(x) + N. The goal is to see which M and N values will be 2 units apart. In this case, that would be choice C where M = -1 and N = 1
We see that f(x) - 1 = f(0) - 1 = 1 - 1 = 0 and g(x) + 1 = g(0) + 1 = -1 + 1 = 0
Therefore, f(x) - 1 and g(x) + 1 have the same y intercept of 0.

jillian calculates that see will take 95 minutes to run 7 miles. she runs the distance in 80 minutes. what is jillians percent error.
Answer:
15.79%
Step-by-step explanation:
do 95-80 which is 15
then do 15/95 as a fraction then multiply that number by 100 to get 15 15/19 then turn that into a decimal and you get 15.79%
Jillian's percent error in estimating the time it would take her to run 7 miles is 15.79%.
Jillian's percent error in her run can be calculated by taking the absolute value of the difference between her estimated time and actual time, divided by the estimated time, and then multiplied by 100 to get the percentage. Here is the calculation step-by-step:
Calculate the absolute difference between estimated time and actual time: |95 minutes - 80 minutes| = 15 minutes.Divide the difference by the estimated time: 15 minutes / 95 minutes = 0.1579.Multiply by 100 to convert to a percentage: 0.1579 times 100 = 15.79%.Therefore, Jillian's percent error in her estimation is 15.79%.

Answer:
A. 22.5° AND D. 22°30’
Step-by-step explanation:
First of all, it's the correct answer on ap*x
To convert π/8 to degrees, replace π with 180°.
π/8 = 180°/8 = 22.5° (A)
Convert 22.5° to degrees minutes seconds

The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

8,000 + 2x
8,000 − 2x
Answer:
8,000-24x
Step-by-step explanation:
there's 24 months in 2 years. If it's value decreased from 8,000 at a constant rate over a 2 year period, the equation would be 8,000-24x
Answer:
B. [tex]8,000-24x[/tex].
Step-by-step explanation:
We have been given that Desmond wants to sell his car that he paid $8,000 for 2 years ago. The car depreciated, or decreased in value, at a constant rate each month over a 2-year period.
Since the value of car depreciates at a constant rate each month, so the value of car depreciated in 2 years would be [tex]2\times 12=24[/tex].
There are 24 months in two years, so value of car depreciated in 2 years would be 24x.
The initial value of car is $8,000, so value of car after 2 years would be [tex]8,000-24x[/tex].
Therefore, option B is the correct choice.

Find the value of a and the value of b
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = (x - h)² + k (h, k) are the coordinates of the vertex
Given y = x² + 7x - 5
To express in vertex form use the method of completing the square
add/subtract ( half the coefficient of the x- term )²
y = x² + 2( [tex]\frac{7}{2}[/tex] )x +[tex]\frac{49}{4}[/tex] - [tex]\frac{49}{4}[/tex] - 5
y = (x + [tex]\frac{7}{2}[/tex] )² - [tex]\frac{49}{4}[/tex] - [tex]\frac{20}{4}[/tex]
y = (x + [tex]\frac{7}{2}[/tex] )² - [tex]\frac{69}{4}[/tex]
Hence
a = [tex]\frac{7}{2}[/tex] and b = - [tex]\frac{69}{4}[/tex]
At a competition with 6 runners, medals are awarded for first, second, and

award the medals?
Decide if this is a permutation or a combination, and find the number of ways
to award the medals.
Answer: 120 different ways. It is a permutation.
Step-by-step explanation:
Because 1st, 2nd, and 3rd are different positions and the order of placing matters, this is a permutation. (In Combinations, the order doesn’t matter, like in choosing people to be on a team without any positions). The calculation is 6x5x4 because there are 6 competitors who could get first, 5 who could get second (the 6th already has first place), and 4 who could get 3rd ( the other two already have 1st and 2nd place).
The number of ways to award the medals in 120 different ways.

Given the coordinates of the vertices of a pre-image figure, describe how to find the coordinates of the image vertices if the figure is translated vertically.
Step-by-step answer:
Step 1:
find out the amount and direction of the vertical translation.
+3 means translating 3 units up, and -6 means translating 6 units down.
Step 2:
to each of the coordinate pairs, add the value of the translation to the y-coordinate (i.e. the second number of the pair).
For example, if the translation is +3, and if one of the vertices is (4,1), then the image of the vertex is (4,1+3) = (4,4).
Repeat for the rest of the vertices.
Step 3:
Check by graphing both image and preimage to see if the shapes are identical. If not, look for a mistake in the translation process.
To translate a figure vertically, add the translation value to the y-coordinates of each vertex. For a translation of 'k' units, the new vertices will be (x, y + k). This keeps the shape the same and only changes its position vertically.
To find the coordinates of the image vertices when a figure is translated vertically,
you need to follow these simple steps:
Identify the translation value: Determine the distance by which the figure is to be translated vertically. Let's say the translation value is 'k' units.Add the translation value to the y-coordinates: For each vertex of the pre-image figure, a translation involves modifying only the y-coordinate.If the original vertices of the pre-image are (x, y), then the new vertices (image) will be (x, y + k).Suppose you have a triangle with vertices A(2,3), B(5,4), and C(1,7). If the figure is translated vertically by 3 units up, the coordinates of the image vertices will be:This method ensures that the shape of the figure remains unchanged and it is only shifted up or down vertically.

A scientist cools some water at a constant rate. the graph and table show how the temperature of the water changes with time.
CAN SOMEONE ANSWER THIS. ?
Answer:
C
Step-by-step explanation:
The easiest way to determine this is to realize that time is the independent variable (n) and temperature is the dependent variable (a).
From the table, we can plug in the two points (n) into n of each equation and see if that equals the temperature values (a).
A little thinking would get us to plug the numbers in C first.
[tex]a(n)=46-(n-1)*4\\46-(5-1)*4=30[/tex]
Works!!
Now, second number:
[tex]a(n)=46-(n-1)*4\\46-(6-1)*4=26[/tex]
Works!!
Hence, C is the correct answer.
Answer:
[tex]a(n)=46-(n-1) \times 4[/tex]
Step-by-step explanation:
It's important to know that the graph is showing a linear function, which means its equation cannot be exponential. So, choices A and B are not correct here.
To find the correct equation, we could find the slope first with the following formula and the two given points
[tex]m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }\\ m=\frac{26-30}{6-5}=4[/tex]
Now, we use the point-slope formula to find the equation
[tex]y-y_{1} =m(x-x_{1} )\\y-30=4(x-5)\\y=4x-20+30\\y=4x+10[/tex]
Notice that choice C has the same coefficient of 4, which is the slope of the line. Therefore, that's the right answer.
Let's prove it for [tex]n=6[/tex]
[tex]a(n)=46-(n-1) \times 4\\a(6)=46-(6-1) \times 4=46-20=26[/tex]
As the table shows.
Therefore, choice C is correct.

A bag has 7 blue marbles, 3 red, 2 green, and 8 white. You pick a marble, record its color, and return it. If you repeat this process 150 times, how many times can you expect to pick a blue or red marble? Write your answer as a percent!
Answer:
50%
Step-by-step explanation:
The total number of marbles is 7 + 3 + 2 + 8 = 20
Blue or red means that the total on any one draw is 7 + 3 = 10
You would expect to draw blue or red 1/2 the time.
Out of 150 throws, you would get 1/2 * 150 which is 75 but that is not what you are asked.
% = (1/2 ) * 100 = 50% of the time
