Answer:
and 
Step-by-step explanation:
Assume that the terminal side of thetaθ passes through the point (−12,5).
In ordered pair (-12,5), x-intercept is negative and y-intercept is positive. It means the point lies in 2nd quadrant.
Using Pythagoras theorem:




Taking square root on both sides.

In a right angled triangle




In second quadrant only sine and cosecant are positive.

Answer:
x^2+2x -6
Step-by-step explanation:
f(x)=2x+1
g(x)=x^2-7
(f+g)(x)= 2x+1+x^2-7
Combine like terms
= x^2+2x -6
Answer:
1 and 2/3 ft squared
Step-by-step explanation:
3 * 1/3 = 1
5 * 1/3 = 1 and 2/3
1 and 2/3 * 1 = 1 and 2/3
F(x) = 3x
F(7) = 21
g(x) = -x + 1
g(7) = -7 + 1 = -6
(F x g)(7) = (21) (-6) = -126
Answer:
if im correct the answer is 70
Step-by-step explanation:
A circle has a 360 degree angle so what I did is i added 85+80+125 and i got 290. 360-290=70
