Answer: 1
13pi/2 can be simplified onto 6 pi/2, so it goes around the unit circle 6 times and left with pi/2. the coordinates of pi/2 is (0,1). the trigonometric function sin is y/r. since r is always 1 on the unit circle, the answer is the y value, in this case it is 1.

Answer:
x < - 3
Step-by-step explanation:
Given the inequality :
-3x + 6 < 15
Collect like terms :
-3x < 15 - 6
-3x < 9
Divide both sides by - 3
-3x / 3 < 9/3
x < - 3 (sign changes as we have divides by a negative)
Answer:
(-22, -18)
Step-by-step explanation:
Midpoint=(
you already know the midpoint, so you're kind of working backward.
Midpoint (-2, 4)
you'll need to work each part of the equation separately to find x and y
x first
-2=
solve for x
multiply both sides by 2
-4 = x+18
subtract (18) from both sides
-22 = x
now y
4=
solve for y
multiply both sides by 2
8 = y+26
subtract 26
y = -18
second endpoint (-22, -18)
Answer:
the answer should be 6/5 I think. If not that then its 5/6
