For the love of all that is holy, i need . a lot of it.
a cylinder has a diameter of 6 feet and a height of 2.1 feet.
what is the volume of the cylinder to the nearest tenth ft³?
use 3.14 to approximate pi.
12.6 ft³
59.4 ft³
237.5 ft³
8550.2 ft³

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
