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!

a baseball is thrown from the top of a building and falls to the ground below. Its path is approximated by the relation h= -5t² + 5t +30, where h is the height above the ground in metres and t is the elapsed time in seconds.

1.draw a diagram that models this situation
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 :(

Readily it can be identified as the ultimate and absolute fact, a statement that is, was, and allways will be true, and if "whole" then it must also be the ONLY one.

Mathmatically it would be an axiomatic algorythm that cannot be disproven.
