7. A rock is thrown with a height equation of h=-1612 20t 5 (where h is the height of the rock in feet at any given time of t in seconds). Will it reach a height of 30 feet? Explain your answer

There are no real solution to the equation when h = 35 ft.

Step-by-step explanation:

Here we have the equation for the height of the rock in ft given as

For the rock to reach 30 ft we must have

That is

or

From which it is observed that since the root of the equation is given by the quadratic formula

b² should be greater than 4·a·c  however

(-20)² (4×16×25)

Hence the equation has only imaginary roots.

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

i dont know sorry
