Answer:
y = a(x-h)² + k
Step-by-step explanation:
I think the formula is: P = P₀. e^(rt)
When P = 2P₀, the formula becomes 2P₀ =P₀.e^(rt)
Simplify by P₀, 2=e^(rt)
ln(2) = lne^(rt)
ln2 = rt.lne or lne =1 then ln2 = rt

Answer: option A
Step-by-step explanation:
The volume of a cylinder can be calculated with the formula:

Where r is the radius and h is the height of the cylinder.
The radius is diameter divided by 2, then:

Substitute the radius into the formula. Then you get the following equation that can be used to find V, the volume of the cylinder:
