Answer: sqrt(2)/2 which is choice D
======================================================
Explanation
(3pi/4) radians converts to 135 degrees after multiplying by the conversion factor (180/pi).
The angle 135 degrees is in quadrant 2. We subtract the angle 135 from 180 to find the reference angle
180-135 = 45
Then you can use a 45-45-90 triangle to determine that the ratio of opposite over hypotenuse is sqrt(2)/2
sine is positive in quadrant 2

Alternatively, you can use a unit circle. Refer to the diagram below. In red, I've circled the angle 3pi/4 radians. The terminal point for this angle has a y coordinate of sqrt(2)/2
Recall that y = sin(theta).
Answer:
from what i know, i just got done with that, the slope is i think 4

Answer:
its the letter 6
Step-by-step explanation:
i took the test
Since you have points (-2,7) you can plug those into each equation to see if they work. If the equation works your answer should be equal to y. in doing that the correct equation is
(B) y=-x+5
y=-x+5
7=-(-2)+=
7=7
Answer:
Each ticket was 3 dollars
Step-by-step explanation:
Since there were 10 friends, let x represent the amount that each ticket cost
10x - 2 = 28
10(3) - 2 = 28
30 - 2 = 28
