Answer:

x=2 y^{2}

Step-by-step explanation:

to get the inverse of

y=2x^2

we have to change its x by a y and its y by an x and then isolate the new y

x=2y^{2} \\ \frac{x}{2} =y^{2} \\\ \sqrt{\frac{x}{2} } =y

D) x = 2y^2, because you find the inverse by switching the x and y in the equation, so y = 2x^2 --> x = 2y^2
To simplify even further, you get
x/2 = 2y^2/2 --> y^2 = x/2
--> y = +/- sr(x/2)

Ravi deposits $600 into an account that pays simple interest at a rate of 4% per year. How much interest will he be paid in the
tamaranim1 [39]
Just find the interest paid after one year, and then multiply the result by 6 (years).  This gives you the amount of simple interest.

The easiest approach would be to use the formula  i = p r t.  In this case p = $600, r = 0.04, and t = 6 years.
