Answer:

f^{-1}(x) will be equal to 9y+18

Step-by-step explanation:

We have given f(x)=\frac{1}{9}x-2

Now let f(x)=y

So y=\frac{1}{9}x-2

We have to find f^{-1}(x) , means value of x in terms of y

So y=\frac{1}{9}x-2

y+2=\frac{1}{9}x

x=9y+18

So f^{-1}(x) will be equal to 9y+18

Please, try typing

  -1
f     (x)  to indicate "inverse function."

Type   f(x) = 1/9x -2    as   <span>f(x) = (1/9)x -2

1) replace f(x) with y:          y = </span> (1/9)x -2
2)  Interchange x and y:      x = (1/9)y - 2
3)  Solve for y:                     9x = y - 18, or y = 9x + 18
4)  replace y with 

  -1
f     (x)   

Then

   -1 
f      (x) = 9x + 18   (answer)

Solve for C:<br> Spam: deiodhwidweiudjegydjwe
Maksim231197 [3]

Answer:

C=\frac{5F-160}{9}

Step-by-step explanation:

Let's solve for C.

F=\frac{9C}{5}

Step 1: Flip the equation.

\frac{9}{5} C+32=F

Step 2: Add -32 to both sides.

\frac{9}{5} C+32+-32=F+-32

\frac{9}{5}C=F-32

Step 3: Divide both sides by \frac{9}{5}.

\frac{\frac{9}{5}C}{\frac {9} {5}}=\frac{F-32}{\frac{9}{5} }

C=\frac{5F-160}{9}

Answer:

C=\frac{F-160}{9}

a cone with a radius of 3” has a total area of 24pie square inches. Find the volume of the cone. 12pie, 24 pie or 15 pie
Ratling [72]

Answer:

12\pi (inches)^{2}

Step-by-step explanation:

Given:

radius of cone = 3 inch

Total area of cone = 24\pi (inch)^{2}

Find the volume of the cone?

We know the area of cone = \pi r(r+s) -------(1)

Where r = radius

Ans s = side of the cone

Put the area value in equation 1

24\pi=\pi r(r+s) -------(1)

\frac{24\pi }{\pi r} =r+s

\frac{24}{ r}-r =s

Put r value in above equation.

s =\frac{24}{ 3}-3

s=8-3

s=5

The side s = 5 inches

We know the side of the cone formula

s^{2}=r^{2}+ h^{2}

h^{2}=s^{2}- r^{2}

Put r and s value in above equation.

h^{2}=5^{2}- 3^{2}

r^{2} = 25-9

r^{2} = 16

r = 4

The volume of cone is

V = \frac{1}{3} \pi r^{2} h

Put r and h value in above equation.

V = \frac{1}{3} \pi (3)^{2}\times 4

V = 12\pi (inches)^{2}

The Volume of the cone is 12\pi (inches)^{2}
