Then evaluate the sine and cosine function. What is the y component of 315 degrees? What is the x component of 315 degrees?

9514 1404 393
Answer:
6
Step-by-step explanation:
The slope of the line between (3, 3) and (4, 9) is given by the slope formula:
m = <average rate of change> = (y2 -y1)/(x2 -x1)
m = (9 -3)/(4 -3) = 6/1
m = 6
The average rate of change on the interval [3, 4] is 6.
For 64 it’s A. , C. , D. and for 3 it’s D. and F
