masha68 [24]

Answer:

Perimeter

Step-by-step explanation:

Perimeter is the distance all round a particular shape. Since we are not given the shape of her bedroom, we may not have a particular formula that was uses to find the perimeter. Despite all that, the only way that she could arrive to conclusion that 36 meters of light are needed, then Supriya it is by finding the perimeter.

What equation is the inverse of y=2x^2-8?
Fynjy0 [20]

Step-by-step explanation:

To get the inverse, swap the x- and y-variables, then solve for y. We should have the equation: x = 2y^2 - 8

Solving for y:    

y = 2x^{2} - 8    because  y + 8 = 2x^{2} or  x =\sqrt\frac{y +  8}{2}

So on interchanging the variable, we get the equation:

x = 2y^2 - 8

x + 8 = 2y^2

y = \sqrt\frac{x + 8}{2}
