Answer:

(2/3)y - (8/3) = x For the first one maybe?


Step-by-step explanation:

1. y = (3/2) x + 4

y - 4 = (3/2) x

(2/3)y - (8/3) = x


2. If output is 2, f(x) = 2.

So, 2 = (3/2) x + 4

-2 = (3/2) x

-4 = 3x

x = -3/4

A cone has a volume of 1,440\pi cubic centimeters and a height of 30 centimeters. What is the diameter of the cone's base?
Varvara68 [4.7K]
We know that
[volume of a cone]=pi*r²*h/3
h=30 cm
volume=1440*pi cm³
r²=3*volume/[pi*h]------> r²=3*1440*pi/[30*pi]----> r²=144-------> r=√144
r=12 cm
so 
the diameter=2*r------> 2*12-----> 24 cm

the answer is
<span>the diameter of the cone's base is 24 cm</span>
