Problem E The white square in the drawing below is located in the centre of the grey rectangle and has a
surface area of A. The width of the rectangle is twice the width a of the square. What is the
surface of the grey arca (without the white square)?

i dont know

step-by-step explanation:

which expression represents the approximate length of bc?

step-by-step explanation:

answer: about 22.67

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.
