Question 94596: please help me solve this. thank you so much.p.s. i put each part of the equation on a separate line so that it would not all squish together. it reads: equation 1 plus equation 2 equals equation 3
2x-10
---------
3x^2-x-14
plus
7
----
3x-7
equals
8
---
x+2

Question 95528: Hi,
I have 2 questions, Im so coonfused.
1) Let P be the point on the unit circle U that corresponds to an angle t. Find the exact coordinates(x,y) of P and the exactvalues of the trigonometric functions at angle t. Use sqrt (2) for the square root of 2 and if the value of a trigonometric function is undefined, enter und. t=(-pi)
x=? y=?
sin(t)=?,cos(t)=?,tan(t)=?,csc(t)=?, sec(t)=?, cot(t)=?
2) Use the fundmental identities to find the values of the trigonometric functions(as decimal values within 0.001) for the give conditions.
sin(t)=0.6, cos(t)<0
sin(t)=?,cos(t)=?,tan(t)=?,csc(t)=?, sec(t)=?, cot(t)=?

Question 96400This question is from textbook Finite mathematics
: An artist is painting a supply of small paintings to sell at an arts festival. He can paint three landscapes per hour and two seascapes. He can frame five paintings per hour. He has 50 hours available for painting and 25 hours for framing.
How many of each type of painting should he paint and frame in order to maximize the total value of the paintings. He receives $25 each for the landscapes and $30 each for the seascapes.This question is from textbook Finite mathematics
