What two numbers are missing from this factor tree for the prime factorization of 189? 3*63 * 3*7 a. 2 and 5 b. 5 and 7 c. 9 and 7 d. 3 and 21

189   = 3*63

       = 3 * 7*9

       = 3 *7 * 3*3

the answer is d. 75%

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.
