, find f^{-1}(x)f −1 (x)

Stolb23 [73]

Answer:

Multiply the numerator by the reciprocal of the denominator. Multiply x x by 1 1 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=1x f - 1 ( x ) = 1 x is the inverse of f(x)=1x f ( x ) = 1 x .

For any circle, which ratio is equal to the number n? Select all that apply. Plsss help me!!

barxatty [35]

Answer:

Options A-C-F

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=\pi D$ or $C=2\pi r$

where

D is the diameter and r is the radius

therefore

$\pi =\frac{C}{D}$ or $\pi =\frac{C}{2r}$

The number pi is the ratio circumference - diameter or is the ratio circumference - 2 times radius

The area of the circle is equal to

$A=\pi r^{2}$

therefore

The number pi is the ratio Area - radius squared

How can you change the equation y = 2x + 3 to function notation?

qwelly [4]

Answer:

$f(x)=2x+3$

Step-by-step explanation:

The first thing that would need to be done is solving for y. This problem has already done this. The next step is to exchange y for $f(x)$

That is all. This would mean that the function notation for the equation would be: $f(x)=2x+3$

The price for a gallon of whole milk has increased from 2006 to 2008. from 2006 to 2007, the cost of whole milk increased by app

valkas [14]

You have the starting price of $1.99. To get the increased price, divide 1.99 by .56 (.56 is the decimal form of 56%). You would get $3.55. This is for the year 2007. So for 2008, divide 3.55 by .42. The answer is $8.45. You can check the answers by multiplying the answers you go the the percentage. Ex. 8.45* .42=3.55 (rounded)
