Derek is working out in order to be in shape for the upcoming football season. he does cardio exercises and strength training. each hour he spends doing cardio burns 200 calories and each hour he spends doing strength training burns 100 calories. derek's coach recommends that he spend more than twice as much time doing cardio exercises as he does doing strength training.

200x + 100y > 3,000

x > 2y

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.
