Answer:
The radius is 8 inches
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
Assuming you mean 320 pi for the volume
320 pi = pi r^2 ( 5)
320 =5pi r^2
Divide each side by 5pi
320 pi / 5pi = 5 pi r^2 / 5pi
64 = r^2
Take the square root of each side
sqrt(64) = sqrt(r^2)
8 = r
The radius is 8 inches
Answer:C(x) = 2000+ 0.05 x
Step-by-step explanation: Cost (C) = fixed cost + (cost per pencil x number of pencils)
Since:
Fixed cost: $2000
Cost per pencil : $0.05
Replacing with the values given:
C(x) = 2000+ 0.05 x
Where x is the number of pencils manufactured.

Answer:
B
Step-by-step explanation:
(x+2y)(x-5y)
do foil method:
x^2-5xy+2xy-10y^2
simplify x^2-3xy-10y^2,
so d is correct.
