Will mark brainliest (0,6.3) , (1,9.3) , (2,12.9) , (3,14) , (4,15.4) , (5,14) , (6,11) a. Student chose the function y = .9286x + 9.0571 to model the function. explain how a quadratic model is more appropraite for this data.

b. write a function that better models the data in the scatter plot, round term to nearest ten-thousandth.​

answer: 1 and 3

step-by-step explanation:

- "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."

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
