Answer:
A
Step-by-step explanation:
Using the pythagorean theorem, 
we plug the numbers in; 
9+36=c^2
45=c^2
sqr root of 45 is 
next find the positive perfect sqr root of 45 which will be 9.
9 goes into 45 5 times so it will be 
Sqr root of 9 is 3 so it will be 
I believe it is 9. I think they are asking that if you plug in the y coordinate 0, and therefore it is asking what the value of x should be so that 2/3x-6 would equal 0. If you plug in 9, you get 18/3 and if you subtract 6 from that, you should get 0
Answer:
64.3738
Step-by-step explanation:
Answer:
Here we want to solve the equation:

First, we can divide both sides by 11^3 to get:


Now remember that:
(√x)^2 = √(x^2) = x
then if we apply this to our equation we get:

now we need to solve:

Then x = 2.002
