Question

PRECALCULUS QUESTIONS?

Answer 1

I'm not looking for the answers. I just forgot how to solve this type of problem.

Answer 2

My guess would be to substitute the given values for \(v_0\) and \(h\) then solve for \(\theta\). Beyond that, I'm lost.

Answer 3

noone appreciates jokes around here..geez

Answer 4

I get sin(theta)cos(theta)=4/11

Answer 5

I didn't know I was supposed to acknowledge it.. Lolz

Answer 6

My old notes from a few months ago? I don't have them. I'm going to college in a few weeks, but I'm trying to brush up on some material

Answer 7

\[\Large h = \frac{ v_o^2 }{ 16 } \sin \theta \cos \theta\]
v=60, h=100 Plug that in, and use this identity \[\large 2 \sin \theta \cos \theta = \sin 2 \theta\]

Answer 9

Try looking at www.purplemath.com - it is a great resource for high school math topics.

Answer 10

Thanks everyone! I'll check it out

Answer 11

@katherine.ok What do you mean you get the equation below?
\[\sin(\theta)\cos(\theta)= \frac{ 4 }{ 11 }\]

Answer 12

when you sub givens you get 4/11. and hint is sinxcosx=(sin2x)/2

Answer 13

so sin2x/2= 4/11. sin2x=8/11, and you know how to do it...

Answer 14

Okay, thank you! :)
