Answer:

The answer is A

Step-by-step explanation:

A proportional function is a function where the output = constant x input

Let's make each of these situations into an equation

A) y = 3.5x

B) y = 40x + 25

C) y = 2x + 56

D) y = 2x + 5

because A is the only one that follows the output = constant x input rule it is the example of a proportional function

A cylinder has a volume of 105 cubic centimeter what is the volume of a cone with the same base and height?

pychu [463]

Answer:

Step-by-step explanation:

The formula of a volume of a cylinder:

$V_1=\pi r^2H$

r - radius

H - height

The formula of a volume of a cone:

$V_2=\dfrac{1}{3}\pi r^2H$

If the cylinder and the cone have the same base (radius) and the same height, then the volume of the cone is three times smaller than the volume of the cylinder.

$V_2=\dfrac{1}{3}\underbrace{\pi r^2H}_{V_1}$

Therefore:

$V_2=\dfrac{1}{3}V_1\toV_2=\dfrac{1}{3}\cdot105\ cm^3=35\ cm^3$
