pls I don't understand the question can u explain
Answer:
Answer:
f(-2) = -10
g(5) = -21
Step-by-step explanation:
for f(-2), substitute x with -2 and do the equation, for g(5) substitute x with 5 and get never 21
An hemispherical dome is half a sphere. If the diameter is 60 m, then the radius is 30 m.
We can use differentials to solve this problem because we are adding a thin layer to the original dome, so the volume of the dome in increased by a differential of itself.
This differential volume that the dome is increased is equal to the volume of the coat of paint.
The volume of the dome can be written as:

Now, we can calculate dV as:

Answer: the paint needed for this coat is approximately 7.92 m^3
It is in the thousand place
