Help with this please.

the theorem states that : a^2+b^2=c^2

therefore

15^2= 10^2+b^2

225=100+b^2

b^2= 225-100

b^2= 125

therefore b= root 125

i’m here for points.

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.
