Julian places eight books on each shelf of a bookcase if he shows 32 books how many shelves are needed

Answer

4 shelves

Step-by-step explanation:

If he could place 8 books on x shelves, that would equal 32 books

so

8x=32

x=4

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.
