Are there any tricks to getting this accomplished quickly? Thanks

For defining a vector space, the book gives an example like this:

"Consider the addition operation f +' g defined by
(f +' g)(x) = f(x) + 3g(x) and the usual scalar multiplication."

What does +' mean?

I have a triangle with sides a=10, b=4, and c=6. I've used the law of cosines to find the sides, but every time I try to find one of the angles, it comes out as 180 degrees. Am I doing something wrong, or is it a trick? It says it's an oblique triangle, gives those three sides, and says use the law of cosines. Thanks for any help!

2.how tall is the building
3.when will the ball hit the ground
4.when does the ball reach its maximum height
5.how high above the building is the ball at its maximum height

would: p(x) = x
mu(x) = e^(x) ??
q(x) = x^2

i'm trying to use this equation: dy/dx + p(x) * y = q(x)

by mu i might the math symbol that looks similar to a "u"

i'm just really confused, i missed that class and just looking at notes to teach myself how to do it :(

(b^2)/(2i) + b/2 - (a^2)/(2i) + a/2

Note: "i" is being used as a variable, not an imaginary number.

Hint: It has something to do with adding.
