You need to set up a linear graph. One side with gallons and the other with dollars. Point 1 will be at (1500, 2.10). Point 2 (1300, 2.95). Draw a straight line through these points in your graph and your graph will then give you the answers to your other questions.
V=(1/3)hpir^2
v=130
h=13
r=x
130=(1/3)(13)pix^2
times both sides by 3
390=13pix^2
divide both sides by 13
30=pix^2
divide both sides by pi
30/pi=x^2
sqrt both sides
x≈3.09
radius is abou 3 units
Answer:
free points
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
A function

where a is the initial value and b is the multiplicative rate of change.
In the function,

5 is the value of b so
5 is the multipicative rate of change
Y^2-y^1/x^2-x^1
15-10/1-3
slope = -5/2
