PLEASE HELP ASAP for 5 stars and brainliest!!


1. Omar set off a rocket in a field. The height h of the rocket in feet can be roughly estimated using the formula

h = -16t^2 + 128t, where t is the time in seconds. How long will it take the rocket to reach a height of 240 feet?



2. Brandi, an amateur skier, begins on the "bunny hill," which has a vertical drop of 200 feet.


Her speed at the bottom of the hill is given by the equation v^2 = 64h, where the velocity v is in feet per second
and the height h of the hill is in feet. Assuming there is no friction, approximate Brandi's velocity at the bottom of the hill.
3. If the equation of the axis of symmetry of a quadratic function is x = 0, and one of the x-intercept is -4, what is the other x-intercept?

For the first first you would divid 16 by 16 and that give you 256 and not your equations is h=256+128 add those together it’s gives you 384

For the second you want to bring you want to turn v^2=64 into v=64 squared than you find the square root of 64 and that is 8.
So 8v

Last one one I don’t really understand fully so can u explain it a little more
