3.25 x 25% = .81
3.25- .81 = $2.44
$2.44 is the sale price
Given :
A graph with a straight line on it.
To Find :
The equation of the line.
Solution :
From the given graph we can see that the line passes through point ( 0,6 ) and ( 4,10 ) .
Also, equation of line passes through two points 
and 
is :
Putting all given values, we get :
Therefore, the equation of line is y - x = 6 .
Answer:
V = a (x + 4)*5 but see below.
Step-by-step explanation:
You're not going to get any kind of answer that gives V = 122 or some other pure number.
Formula
V = arh
Givens
a = pi * r
r = (x + 4)
h = 5cm
Solution
V = a * (x + 4)*5
or
V = pi * (x + 4)^2 * 5
There is no indication of which one to choose.
Answer:
305.78 in2
Step-by-step explanation:
The rocket has two parts: one is a cylinder and the other is a cone.
To find the total volume of the rocket, we need to find firstly the volume of each part.
The cylinder has a radius of 2 inches and a height of 2*12 + 5 - 7 = 22 inches, so its volume is:
V1 = pi * r^2 * h = pi * 2^2 * 22 = 276.46 in2
The cone has a radius of 2 inches and a height of 7 inches, so its volume is:
V2 = (1/3) * pi * r^2 * h = (1/3) * pi * 2^2 * 7 = 29.32 in2
Then, we have that the volume of the rocket is:
V = V1 + V2 = 276.46 + 29.32 = 305.78 in2
It will be 89 because it increases by 4 each time
