The water level in a lake was 12 inches below normal at the beginning of
March. The water level decreased by 24 inches in March and increased by 12
inches in April. What was the water level compared to normal at the end of
April? Explain how you solved this problem.

step-by-step explanation:

their are no angles. sorry cant .

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.

hope this !
