While writing a novel, Jared takes a piece of paper and crumples it into a paper ball. Frustrated with his writing, he tosses the paper ball into a trash can. The quadratic function h(t) = -t? +5+ + 6 can be used to model the toss,
where h(t) represents the height of the paper ball, in feet, and t represents the time, in seconds.
Select the equivalent form of the function that provides the needed information. Use each form of the function only one time

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
