Answer:

B. 4

Step-by-step explanation:

A direct proportion has the form

y = kx or k=y/x,

where k is the proportionality constant.

Let's test some points.

Second point

k = 8/2 = 4

Fifth point

k = 23/5.75 = 4

You will get the same result for every point, so the constant of proportionality is 4.

katrin [286]

Answer:

x = 5.477 s

Step-by-step explanation:

Your full question can be found in the image below

We can easily solve this question by using a graphing tool or calculator to plot the equation

f(x)=-5x^2 +200

See second attached picture

The ball is 50 meters from the ground when

50 =-5x^2 +200

-150  =-5x^2

x^2 = 30

x = 5.477 s
