Given g(x)=3/x^2+2x find g^-1(x)

attashe74 [19]

Answer:

Inverse function is: $g^{-1}x=\frac{-x\pm\sqrt{x(x+3)}}{x}$

Step-by-step explanation:

Given Given the function $g(x)=\frac{3}{x^2+2x}$

we have to find the inverse function of g

To find inverse following steps are:

Step 1: Replace g(x) with y

Step 2: Replace every x with a y and every y with x

Step 3: Solve the equation obtained from Step 2 for y.

Step 4: Replace y with g−1(x).

$g(x)=\frac{3}{x^2+2x}$

To find the inverse, let $y=\frac{3}{x^2+2x}$

Now, solve for x

$y(x^2+2x)=3$

$yx^2+2yx-3=0$

$x=\frac{-2y\pm\sqrt{4y^2-4y(-3)}}{2y}$

$x=\frac{-2y\pm\sqrt{4y^2+12y}}{2y}$

$x=\frac{-2y\pm2\sqrt{y^2+3y}}{2y}$

$x=\frac{-y\pm\sqrt{y(y+3)}}{y}$

Replace every x with a y and every y with x , we get

$y=\frac{-x\pm\sqrt{x(x+3)}}{x}$

Replace y with g−1(x).

$g^{-1}x=\frac{-x\pm\sqrt{x(x+3)}}{x}$

So inverse function is: $g^{-1}x=\frac{-x\pm\sqrt{x(x+3)}}{x}$

What is the total price on a suit which sells for $490.50 if the tax is 8%?

daser333 [38]

Answer:

The total price is $529.74

Step-by-step explanation:

This question is an example of percentage increase.

To work out the total price you would first have to convert the percentage into a decimal. You can do this by dividing the percentage of 8% by 100, this gives you 0.08. This is because percentages are out of 100.

The next step is to add the value of 0.08 and 1, this gives you 1.08. This is because you are working out the percentage increase.

The final step is to multiply the amount of $490.50 by the value of 1.08, this gives you $529.74. This is because we are finding the percentage increase of 8%.

1) Divide 8 by 100.

$8/100=0.08$

2) Add 0.08 by 1.

$1+0.08=1.08$

3) Multiply $490.50 by 1.08.

$490.50*1.08=529.74$

Solve for x: 4 over 5 x + 4 over 3 = 2x x = __________________ Write your answer as a fraction in simplest form. Use the "/" sym

alexgriva [62]

Let's see.

4x/5 + 4/3 = 2x

First we have to make each denominator the same, so I'll multiply 4x/5 by 3/3, 4/3 by 5/5, and 2x by 15/15

Now we have 12x/15 + 20/15 = 30x/15

With everything in the same denominator we can solve the new equation of
12x + 20 = 30x

20 = 18x

10 = 9x

X= 10/9
