Michael has a fish tank that has a length of 7 inches,a width of 6 inches and a height of 8 inches. What is the total surface ar
White raven [17]

Answer:

292 inches^2

Step-by-step explanation:

So to start off this is a picture of the fish tank.

Next we will find the area of the bottom and top rectangles.

The side lenghts for those two is 7 and 8.

So the area of one is 56 and the area of 2 is 112 inches^2.

Now we will find the area of the left and right rectangles.

The side lenghts are 6 and 8.

So the area of 2 is 96 inches^2.

Now for the front and back rectangles.

The side lenghts for those two are 6 and 7.

So the area of both is 84 inches^2.

So after adding all the areas up the surface area is 292 inches^2.

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

=x
