a landscape light at ground level lights up the side of a tall building that is 15 feet from the light. a 6 ft man starts fwalking on flat terrain from the light direclty toward the building, how fast is he walkign when he is 9 feet from the light if his shdaow ion the building is shrinking at 2 ft at that instant

use formula for the circle a=3.14

step-by-step explanation:

the answer is 31.27mph

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.
