Answer:

x = 8

Step-by-step explanation:

The first step would be to move all terms with x to one side of the equation:

60 + 50.45x = 57.95x --> 60 + 50.45x - 50.45x = 57.95x - 50.45x -->

60 = 7.50x

The last step to obtain x is to divide both sides by the coefficient of (number next to) x:

60/7.50 = 7.50x/7.50 --> 8 = x

What is the equation process to this question?

The given equation is $h(t)=-16t^2+80t+4$ where h is the height, in feet, of a ball and t is the time, in seconds.

<u>Part a: The height of the ball when t = 2 seconds:</u>

The height of the ball above the ground 2 seconds after it is released can be determined by substituting t= 2 in the equation $h(t)=-16t^2+80t+4$ , we get;

$h(2)=-16(2)^2+80(2)+4$

Simplifying the terms, we get;

$h(2)=-64+160+4$

$h(2)=100$

Thus, the height of the ball after 2 seconds is 100 feet.

<u>Part b: The height of the ball when t = 4 seconds:</u>

The height of the ball above the ground 4 seconds after it is released can be determined by substituting t = 4 in the equation $h(t)=-16t^2+80t+4$ , we get;

$h(4)=-16(4)^2+80(4)+4$
