Rachel decided to have bouncy balls as a party favor. she determines that her ratio of bouncy ballstwo guest is 9: 3. explain how to find the number of balls needed for30 guest

90

Step-by-step explanation:because  if you times 10 to get 30 so you also times it by 9 so 9 x 10 = 90

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.

70
