Solve for x. 50 = x^2 Show your work.
2 answers:
50 = x^2
To isolate x you need to do the opposite of an exponent, which would be square root.
= x
That is the exact form, in other words your answer, if teacher is looking for a decimal, it would be
7.07 = x
Your answer would be 5 squared 2 and the reason for that is if you're looking for the simplest radical form you do 50 divided by 2 which is 25 and you do 25 / 5 because that's the next available divisor and then you would put the five on the outside of the of the square root symbol and then you would put the two on the inside.

Answer:
See the proof below.
Step-by-step explanation:
For this case we need to proof the following identity:
So we need to begin with the definition of tan, we know that and we have this:
(1)
We also have the following identities:
And if we apply those identities into equation (1) we got:
(2)
We can divide numerator and denominator from expression (2) by like this:
And if we simplity we got:
And with that we complete the proof. And that appies for all
This is how you graph it.
