Can you also explain how you solve it so i can do by myself: ) what is the sum of the first eight terms of the series? (−500)+(−100)+(−20)+(−4)+(−0.8)+ round the answer to two decimal places if necessary. −996.09 −625 −624.99 −623

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.
