Will mark brainliest!

I'm doing a Roller coaster project for Algebra 2 and am needing some assistance. I've posted an attachment of what it should look like. All I need is three equations so I can make the coaster. Any help is appreciated. Thank you in advance. (You can't use the same equations given in the example)

Aprojectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t2 + 704t. after how many seconds does the projectile take to reach its maximum height?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

If f(x) = 6x – 4, what is f(x) when x = 8? a2 b16 c44 d52
