Answer:

The width of the rectangle is 12.1 meters

Step-by-step explanation:

Step 1: Find the width

2w + 2(w + 2.3) = 53

2w + 2w + 4.6 = 53

Step 2: Combine like terms

2w + 2w + 4.6 = 53

4w + 4.6 = 53

Step 3: Subtract 4.6 from both sides

4w + 4.6 - 4.6 = 53 - 4.6

4w = 48.4

Step 4: Divide both sides by 4

4w / 4 = 48.4 / 4

w = 12.1

Write the given expression in terms of i : √-245

tankabanditka [31]

Okay, so first things first:
i = $\sqrt{-1} 
$
That said, no answer that has -245 is correct.

Now we just need to solve $\sqrt{245}$
245/5=5*49
$\sqrt{5} * \sqrt{49} = 7i*\sqrt{5}$
So, that's your answer, option D.

Which equation is the inverse of y = 9x2 - 4?

m_a_m_a [10]

Answer:

The inverse will be:

$y' = \frac{\sqrt{x+4}}{3}$

Step-by-step explanation:

In order to find the inverse of the equation, we do a variable change, since we are finding the inverse, :

$f(x) = 9x^{2} - 4$

$y = 9x^{2} - 4$

$x = 9y' ^{2} - 4$

Now solve for y'.

First add 4 in both sides of the equation and change to the left y'.

$x + 4= 9y'^{2} - 4+4$

$9y'^{2}$ = x + 4

Second divide by 9

$9y'^{2}$ /9 = (x + 4)/9

$y'^{2}$ = (x + 4)/9

Now you will have to clear y, with the square root.

$[tex]y'^{\frac{2}{2}} = \sqrt{x + 4} / \sqrt{9}$ [/tex] =

Simplifying terms

$y' = \frac{\sqrt{x+4}}{3}$

$f^{-1}(x) = \frac{\sqrt{x+4}}{3}$

You can check the answer by doing the evaluation of the following equation:

(f o $f^{-1}$ ) (x)

substitute the equation for y' or inverse function $f^{-1}$

f( $\frac{\sqrt{x+4} }{3}$ )

Now substitue the value into f(x)

You will have

$= 9(\frac{\sqrt{x+4} }{3}} )^{2} - 4\\\\Solving\\\\9(\frac{{x+4} }{9}} ) - 4$
