Ariel weighed an object on her balance and recorded a mass of 24.3 grams. her teacher told her that there was obviously something wrong with her balance because it was giving her a reading which was 30.0% too high. what was the actual mass of the object?

the answer is true.

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.
