Pre-Calc Help

[graceful tulip]

Hi I need help with problems 4 and 5 I literally have no idea where to begin or how to slove them. Can I get all the steps to each problem and an explanation? It would literally save my life.

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

For 5 do the following

1. Get both equations in the form x^2 = …
2. Use the transitive property (if a = b and b = c then a = c). This should get you an equation with just y
3. Solve the quadratic

For 4, find a root of p(x) by trial error, call it a, divide p(x) by (x-a), then solve the quadratic

To make this faster, I’d suggest looking up synthetic division

what about problem 3 and 2?

3? it tells you to just draw the triangle out...

2, well you need to simplify that thing greatly, so just see what you can do in terms of simplification :D

3. Remember that tan(angle) = opposite/adjacent

What would the side opposite of the angle be? What about the side adjacent to?

5, pull off substitution
