ASAP! find the inverse of the function y=2x^2+2
jeka57 [31]

Answer:

\displaystyle y=\sqrt{\frac{1}{2}x -1}

Step-by-step explanation:

We want to find the inverse of the function:

y=2x^2+2

To find the inverse of a function, we will flip the variables and solve for <em>y</em>. So:

x=2y^2+2

Solve for <em>y</em>. Subtract two from both sides:

x-2=2y^2

Divide both sides by two:

\displaystyle y^2=\frac{1}{2}x-1

And take the principal square root of both sides. Therefore:

\displaystyle y=\sqrt{\frac{1}{2}x -1}

A spinner has 5 sector's of equal size. The sectors are labeled 1,2,3,4, and 5. the spinner is spun twice.x is the number of tim
LuckyWell [14K]

Answer:

Because the sectors are of equal size, each sector has the same probability of happening.

So for every number, you have a probability of 0.2 of it appearing.

Because you have three odd numbers, the probability to land on an odd number on each spin is 0.6. You can also say that the probability to not have an odd number is 0.4.

So what is the probability to have 0 odd number in two spins?

What is the probability to have 1 odd number in two spins? You can have one odd number on the first or one odd on the second spin, that is why we add the probabilities.

What is the probability to have 2 odd numbers in two spins?

To verify if we did a good job, we add all the probabilities. We should get 1.

.

So to slide your bars, you slide them up to the number I gave you for each case.

Hope this helps!
