Can anyone help me with this geometry question? I just don't know what is the last step, we are trying to prove that BD bisects angle ADC

594 square inches

step-by-step explanation:

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.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
