Question

How do you convert this to rectangular form??

x = (80cos(35))t
y = 7 + (80sin(35))t - 16t^2

Answer 1

Answer 2

isolate t in the first equation, then plug it into the second equation

Answer 3

x = (80cos(35))t

x/(80cos(35)) = t

t = x/(80cos(35))

Answer 4

plug that into y = 7 + (80sin(35))t - 16t^2

Answer 5

Oh, sorry afk

Answer 6

thats ok

Answer 7

So it is -((16)x^2)+x+7???

Answer 8

Answer 9

not quite

Answer 10

What did I mess up?

Answer 11

you should have a sin(35)/cos(35) term in there somewhere

Answer 12

or a tan(35) since sin(x)/cos(x) = tan(x)

Answer 13

So it is -((16)x^2/tan35)+x+7

Answer 14

closer but please post your steps so I can see how you got that

Answer 15

Nevermind, I did it over, and I see.

Answer 16

alright great
