Thank you for posting your question here at . I hope the answer will help you. Feel free to ask more questions.
Below are the choices that can be found elsewhere:

k = 2Px2
k = Px2
k = 2p/x^2
k = x/2x^2

The equation should she use is k = 2p/x^2

Answer from: david1236544

$k=\frac{P}{x^2}$

Step-by-step explanation:

Given formula of potential energy,

P=kx^2

For finding the formula for k,

We need to isolate k,

Divide both sides of the equation by x^2

We get,

$\frac{P}{x^2}=\frac{kx^2}{x^2}$

$\frac{P}{x^2}=k$

Hence, the required formula would be,

$k=\frac{P}{x^2}$

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

Answer from: Quest

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
