What is the scale factor and how do I find it? Please help!!

Take one of the sides from each shape (they have to be corresponding) so say you take side AB on one of the shapes the length is 6 and on the other shape the length is 3. Put the number of the smaller shape on the top of the fraction and the number of the larger shape on the bottom of the fraction. So it would be 3/6 then just simplify and the answer should be 1/2

Answer

1 number

explanation

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.
