Find the volume of the cylinder. Find the volume of a cylinder with the same radius and double the height.
The volume of the cylinder is ?
The volume of a cylinder with the same radius and double the height is ?
Answer:
Step-by-step explanation:
The volume of the original cylinder = pi * r^2 * h
Givens
r = 6 in
h = 3 in
pi = 3.14
Solution
V = pi * r^2 * h
V = 3.14 * 6^2* 3
V = 3.14 * 36 * 3
V = 339. 12
Part 2
If you double the height, you will double the volume
V = 3.14 * 36 * 6
V = 678.24

Answer:
y=-5/3x-1
Step-by-step explanation:
Of course! Two parallel lines will have the same slope. So, we have to eliminate all equation that dont have the slope -5/3. We are left with the third option.

Given f(x) = -2x and g(x) = 4x - 8, find h(x) = f(x) + g(x).
f(x) = -2x and g(x) = 4x - 8, find h(x) = f(x) + g(x).
Replace f(x) and g(x) with their given values:
h(x) = -2x + 4x -8
Combine like terms:
h(x) = 2x -8
Sally works in a cell phone store. She is paid a weekly salary of $80 plus $5.25 for each cell phone she sells. Which equation can be used to find Sally's total weekly income?
F- y = 5.25x + 80
G- y = 80x +5.25
H- y = 85.25x
J- Not here
First, let's define some variables.
x = # of cell phones sold.
y = total weekly income.
y = $5.25x + $80
F is the correct answer choice.
If p(x) = x2 - 1 and 9(x) = 5(x - 1), which expression is equivalent to (0-9)(x)?
5(x - 1) - x2 - 1
(5x-1) - (x² - 1)
(x2 - 1) - 5(x - 1)
(x2 - 1) - 5x-1
Answer:
x^2 -1 - 5(x-1)
Step-by-step explanation:
p(x) = x^2 - 1 and q(x) = 5(x - 1)
p(x) - q(x) = x^2 - 1 - ( 5(x-1))
Distribute
= x^2 -1 - 5(x-1)
find the area of the circle. use 3.14 for π. do not round answer
Radius = 14 : 2 = 7 in.
Area = 7 x 7 x 3.14 = 153.86 (in2)
Answer:
153.86 in²
Step-by-step explanation:
Before finding the area of the circle, first, let us find the radius.
d = 2r14 = 2r
Divide both sides by 2.
7 in = r
And now let us find the area of the circle.
Area = π r²= 3.14 × 7 × 7
= 21.98 × 7
= 153.86 in²
Statins are used to keep cholesterol in check and are a top-selling drug in the U.S. The equation: S − 1.9 x = 4.9 gives the amount of sales ( S ) of statin in billions of dollars x years after 1998. According to this equation, how much will/did people in the U.S. Spend on statins in the year 2005? Answer: People in the U.S. Will spend billion dollars on statins in 2005.
Answer:
People in the U.S. Will spend 18.2 billion dollars on statins in 2005.
Step-by-step explanation:
Given:
S − 1.9x = 4.9
Where,
S = sales of statin in billions of dollars
x = years after 1998
how much will/did people in the U.S. Spend on statins in the year 2005?
2005 is a year after 1998
Number of years = 2005 - 1998
= 7
x = 7 years
S − 1.9x = 4.9
S - 1.9(7) = 4.9
S - 13.3 = 4.9
Add 13.3 to both sides
S = 4.9 + 13.3
= 18.2
People in the U.S. Will spend 18.2 billion dollars on statins in 2005.

What is the slope of a line that is perpendicular to the
graph of y=1/6x+8 ?
Select one:
-6
6
1/6
-1/6
Answer:
A. -6
Step-by-step explanation:
The slope of the line that is perpendicular to the graph y = ⅙x + 8, is a negative reciprocal of the slope of the graph, y = ⅙x + 8.
What this means is that, if you multiply the slope of y = ⅙x + 8, and the slope of the line perpendicular to it, you would have -1. That is [tex] m_1 * m_2 = -1 [/tex].
Where,
[tex] m_1 [/tex] = slope of y = ⅙x + 8.
[tex] m_2 [/tex] = slope of the line perdendicular to y = ⅙x + 8.
The slope of y = ⅙x + 8 is ⅙.
Substitute [tex] m_1 [/tex] = ⅙ into [tex] m_1 * m_2 = -1 [/tex], to find the slope [tex] (m_2) [/tex] of the line that is perpendicular to the graph of y = ⅙x + 8.
[tex] \frac{1}{6} * m_2 = -1 [/tex]
Multiply both sides by 6
[tex] \frac{1}{6} * m_2 * 6 = -1*6 [/tex]
[tex] 1*m_2 = -6 [/tex]
[tex] m_2 = -6 [/tex]
The slope of the line that is perpendicular to the graph of y = ⅙x + 8 is -6.

Tracy has a cell phone plan that provides 250 free minutes each month for a flat rate of $29. For any minutes over 250, Tracy is charged $0.35 per minute. Which of the following piecewise functions represents charges based on Tracy's cell phone plan?
Answer:
[tex]\frac{29,x\leq 250}{29+0.35(x-250)x\geq 250}[/tex]
Step-by-step explanation:
Let x represent the total time spent calling and f(x) represent the charges.
Since Tracy is charged $29 for 250 free minutes, hence:
For x ≤ 250, f(x) = $29
Tracy is charged an extra $0.35 per minute for calls over 250 minutes, hence:
For x ≥ 250, f(x) = 29 + 0.35(x - 250)
Therefore this can be represented by the piecewise function:
f(x)= [tex]\frac{29,x\leq 250}{29+0.35(x-250)x\geq 250}[/tex]
A rectangular table that is placed lengthwise against a wall is 8 feet long
and 4 feet wide. Balloons will be attached 8 inches apart along the three
exposed sides, with one balloon at each of the four corners. How many balloons are needed?
Considering the perimeter of the rectangular table, it is found that 36 ballons are needed.
What is the perimeter of a rectangle?The perimeter of a rectangle of length l and width w is given by:
P = 2(l + w).
In this problem, the dimensions of the table are l = 8 ft and w = 4 ft, hence the perimeter is of:
P = 2(l + w) = 2 x 12 = 24 ft.
Ballons will be attached 8 inches = 2/3 feet along the perimeter, hence the number of ballons needed is given by:
[tex]n = \frac{24}{\frac{2}{3}} = 36[/tex]

Answer:
y = 1/4x + 17/4
Step-by-step explanation:
first lets umm find the slope
use points that you can um clearly see ?
(4, 6) and (8, 7)
so use the equation y2 - y1/ x2 - x1
soooo
7 - 6/ 8 - 4
1 / 4
so it looks like:
y = 1/4x + b
so far
now we have to find the y-intercept with a point we did not use yet
but i have a little trouble so ill try my best to estimate a point
(2, 5)
we substitue
5 = 1/4(3) + b
5 = 3/4 + b
b = 5 - 3/4
b = 17/4

Evaluate the function rule below when x= -2
f(x)=-x+2
Answer:
f(- 2) = 4
Step-by-step explanation:
substitute x = - 2 into f(x) , then
f(- 2) = - (- 2) + 2 = 2 + 2 = 4
Answer:
Given function: [tex]f(x)=-x+2[/tex]
To evaluate the function when [tex]x=-2[/tex], substitute the given value for [tex]x[/tex] into the function and solve:
[tex]\implies f(-2)=-(-2)+2[/tex]
[tex]\implies f(-2)=2+2[/tex]

On factorization of the equation x² − x − 6 = 0. Then the values of x are −2 and 3.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The equation is given below.
x² − x − 6 = 0
On factorization, we have
x² − 3x + 2x − 6 = 0
