Below are several points on the graph of a polynomial. Which of the following statements are true about the graph of this polynomial? Check all that apply. A. The graph has a maximum value between y = 1.5 and y = 2.
B. There is a maximum between x = 0 and x = 1.
C. The graph has a minimum value between y = 1.5 and y = 2.
D. There is a minimum between x = -1 and x = -2.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

step-by-step explanation:

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
