7. ⬆️⬆️ 8. state the y coordinates
9. state the value of the length of PR
10. state the length of XY
11. Is XY=1/2 PR yes or no
i’ll give brainiest

As per diagram we have:

8

Coordinates of X:

Coordinates of Y:

9

Length of PR:

10

Length of XY is:

11

a is the right answer

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.
