The equation −16x2 + 10x + 15 = 0 represents the height, in feet, of a flotation device above the water after x seconds. The linear term represents the initial velocity. The constant term represents the initial height.



a. If the initial velocity is 0, when should the flotation device land in the water?
b. If the initial height is 0, when does the flotation device land in the water?

Answer:

A: 0.968 B: 0.625

Step-by-step explanation:

for part A:

since the linear term represents the velocity and the initial velocity is 0 then, 10x = 0. so our function is now

-16x^2 -15 =0

if we solve for x then we get both a negative and positive value but we only choose the positive one since time cant be negative.

x = 0.968

For part B:

since the constant represents the height and the initial height is 0 the equation becomes:

-16x^2 + 10x = 0

we solve for x once more and we get x = 0.626

make sure to ask if you need any further help.

and I would really appreciate a brainliest! :)
