# Fun Math.. CLICK ME!!!?

I need help on my last question on my homework. I really dont get this.

In this activity, you will use what you have learned about quadratic equations and their graphs to calculate the amount of time water projected from a given fountain stays in the air, and how high it travels into the air based on the speed at which it is projected.

Recall the equation for projectiles is y = –16x2 + vx + s, where y is the object’s current height (in feet) at any time after it is projected, x is the time (in seconds) the object has been in the air, v is the object’s starting upward velocity, and s is the object’s starting height.

Feel Free to use graphing technology.

You didn't ask a question. What don't you understand?

They give you a formula and explain all the terms

x is the time

v is the velocity at time 0

s is the height at time 0

y is the height at time x

What are you being asked to do?
