Question

I NEED HELP PLEASEEEEE!!!!!!!!

Answer 1

Can ANYBODY help me with this paper!?????!?!??!?

Answer 2

So you have the correct parametric, you just need h=2.5 in the second equation.

You should then plot it to answer the other equations.

The final equation will be (x,y) but sub your parametric equations for x and y.

Answer 3

Here's your plot - http://www.wolframalpha.com/input/?i=parametric+%28136*cos%2829%29+*+t%2C136*sin%2829%29+*+t-16t%5E2%2B2.5%29

Answer 4

How long is y > 0?

Answer 5

That tells you how long it is in the air.

Answer 6

What is the maximum value of x that you see there? Is it greater than 415? If so, he hits a homerun.

Answer 7

$$
Path=(136*\cos(29) * t,136*\sin(29) * t-16t^2+2.5)
$$
Just multiply everything and leave "t" alone, that's your rectangular coordinate.
