Abaseball is thrown into the air from the top of a 224-foot tall building. the baseball's approximate height over time can be represented by the quadratic equation h(t) = -16t2 + 80t + 224, where t represents the time in seconds that the baseball has been in the air and h(t) represents the baseball's height in feet. when factored, this equation is h(t) = -16(t - 7)(t + 2). what is a reasonable time for it to take the baseball to land on the ground? -2 seconds -9 seconds -5 seconds -7 seconds

7 seconds

Step-by-step explanation:

Given :

A baseball is thrown into the air from the top of a 224-foot tall building.

The baseball's approximate height over time can be represented by the quadratic equation

To Find:  What is a reasonable time for it to take the baseball to land on the ground?

Solution:

Equation :

When factored this equation :  --A

Now we are supposed to find  reasonable time for it to take the baseball to land on the ground i.e. h =0

So, substitute h = 0 in A

Since time cannot be negative

So, neglect -2

Thus it will taker 7 seconds for baseball to reach the ground.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
