Heather is training for a long distance run. Her data points listed below represent the days of practice, x, and the number of miles run, y.

(1, 2.5), (2,4.2), (4,5,6), (6,7), (8, 8.1), (10, 11)

Use the equation to interpolate the value and estimate the distance that she could have run on day 3. Round

to the nearest tenth of a mile.

day 3

miles

s

step-by-step explanation:

b is the correct answer

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.
