If charlotte started doing her homework 9: 15 and she finished 7 and a half hours later, what time did she finish?

if its 9:15 am then it was 4:45 pm if it was am then it was pm

2,600 divided by 80 = 32.5

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.
