Robby and his friend, Sal, are at the top of a lookout tower. Sal dares Robby to drop one of his favorite Jordans from the top of the 210 feet tall platform. The height h of the shoe in feet after x seconds is modeled by the function h(x) = −142 + 210. How long will it take, in seconds, for the shoe to reach the ground?

About 1.48 seconds

Step-by-step explanation:

"Reach the ground" means that at the very moment that happens, the height of the shoe is 0.

The question now is, what value of x that will make the height (the value of the function) equal to 0.

Assumine the function is h(x) = -142x + 210 (I don't see x in the formula for the function.)

Solve for x:

-142x + 210 = 0

Subtract 210.

-142x = -210

Divide by -142.

x = -210 / -142 = 1.48 seconds (rounded to nearest hundredth)

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
