In a circle, a 90degrees sector has area 144pi in2. What is the radius of the circle?

RUDIKE [14]

Answer:

The radius of the circle is 24 inches.

Step-by-step explanation:

Central angle in a sector is 90 degrees

Area of a sector is $144\pi\ \text{inch}^2$

The area of sector is given by the formula as follows :

$A=\dfrac{\theta}{360}\pi r^2$

r is the radius of circle

$r=\sqrt{\dfrac{360 A}{\theta \pi}} \\\\r=\sqrt{\dfrac{360 \times 144\pi }{90\times \pi}} \\\\r=24\ \text{inch}$

So, the radius of the circle is 24 inches.

What is the inverse of x^2-4x+5

lisabon 2012 [21]

we are given

$f(x)=x^2-4x+5$

Since, we have to find inverse of this function

step-1: we set f(x)=y

$y=x^2-4x+5$

step-2: switch x and y

$x=y^2-4y+5$

step-3: Solve for y

$y^2-4y+(5-x)=0$

now, we can use quadratic formula

$y=\frac{4+\sqrt{4^2-4(5-x)} }{2}$

$f^{-1}(x)=\sqrt{x-1}+2$

$f^{-1}(x)=-\sqrt{x-1}+2$ ..............Answer
