Can someone me , and explain how they got this?

a straight line in an angle is a supplementary angle which is equal to 180 degrees. Since 128 is given, you subtract the two numbers so your answer will be 52 degrees

the aswere is the one with all 8's and the second one is with the 10,8 and 6

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.
