Answer:

$1-\frac{\sqrt{3} }{4}-\frac{\pi}{6}$

Step-by-step explanation:

The missing figure is shown in the attachment

The area of the shaded region = Area of Square - (Area of sector AOB + Area of equilateral triangle BOC + Area of sector COD)

Area of Sector AOB=Area of Sector COD= $\frac{30}{360}*\pi*1^2=\frac{\pi}{12}$

Area of equilateral triangle = $\frac{1}{2}*r*\frac{\sqrt{3} }{2}*r= \frac{1}{2}*1*\frac{\sqrt{3} }{2}*=\frac{\sqrt{3} }{4}$

Area of shade region = $1^2-\frac{\sqrt{3} }{4}-\frac{\pi}{12}*2$

$1-\frac{\sqrt{3} }{4}-\frac{\pi}{6}$

If f(x) = 11x – 5, then f^-1(x)=

MAVERICK [17]

Answer: $f^-^1(x)=\frac{x+5}{11}$

Step-by-step explanation:

To find the inverse, you replace the x with y, and y with x.

$x=11y-5$ [add 5 on both sides]

$x+5=11y$ [divide both sides by 11]

$\frac{x+5}{11} =y$

$f^-^1(x)=\frac{x+5}{11}$
