How many miles do you have to walk in a three day period to reach 6 2/3 miles

approx. 2.2 miles

Step-by-step explanation:

If we put 2/3 into a decimal, (.66) we then add it to the 6 miles, aprox. 6.6 miles. Divide 6.6 by 3,

and you're answer is 2.2.

Approx. 2.2 miles a day over a 3 day period.

d? maybe

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
