Answer:

B. -1

Step-by-step explanation:

The relevant points on the graph are (1, 3) and (4, 0). The average rate of change can be found using the slope formula ...

m = (y2 -y1)/(x2 -x1)

m = (0 -3)/(4 -1) = -3/3 = -1

The average rate of change from x = 1 to x = 4 is -1.

Could someone explain how they get the answer for this?

jarptica [38.1K]

Answer:

40°

Step-by-step explanation:

The reference angle is the positive acute angle created by the terminal arm and the x-axis.

The highlighted red in the picture below shows what we're looking for.

The arm rotated 220° (but 'backwards' so the value given is negative).

|-220°| - 2(90°) <= Subtract two right angles for two quadrants

= 220° - 2(90°)

= 220° - 180°

= 40°

Therefore, the reference angle is 40°.

If you got 50°, you probably calculated the angle with the terminal arm and the y-axis. Remember to always use the nearest side of the x-axis!
