Triangle ABC has vertices A(1,1), B(2.5,3), and C(0,-3). It is dilated by a scale factor of 1/2 about the origin to create triangle A'B'C'. What is the length, in units, of sides line B'C'?

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.

the correct answer is c
