helppppp

The quarterback of a football team releases a pass at a height of 7 feet above the playing field, and the football is caught by a receiver at a height of 4 feet, 30 yards directly downfield. The pass is released at an angle of 35 degrees with the horizontal.

a) Write a set of parametric equations for the path of the football.

b) Find the speed of the football when it is released.

c) Use a graphing utility to graph the path of the football and approximate its maximum height. (I KNOW HOW TO DO, I JUST NEED PARAMETRIC EQUATIONS)

d) Find the time the receiver has to position himself after the quarterback releases the football.

yes @con
but this isn't really hard, you just need trig

@cat
i did
nothing

facepalm @frenzo
there are 4 parts to this problem
it isn't multiple choice

okay guys just skip parts b, c, and d
all i need are the parametric equations for x and y

I know a function for it but not parametric equation

y = -.003333x^2 + 7

isnt it just like

x = vcost

or something like that

not physics this is alg 2

dealing with maxheight speed/parabolas not sine cosine tangent and arcsine arccosine etc

no

He's talking about parametric equations

They're different from rectangular functions.
