Answer:
The last image (The one going through points (4,1) and (8,2))
Step-by-step explanation:
If the side length is y, and the perimeter is x, x is equal to that value times 4. This means the table of points would look like this:
x y
4 1
8 2
12 3
And so on. The only graph that is going through these points is the last one. The third graph is wrong because it's the opposite, (1,4) instead of (4,1), and the perimeter will be greater than the side length.
So 13x5=65 and 7*6=42, add them up and get 107. So, Paul saved $107 for 11 weeks
Hi!
Square roots where the things under the root are multiplied (for example
) can be split up into
.
That's what I'm going to do in this case. I'm going to split
into ![\sqrt[3]{125} * \sqrt[3]{x^{12}}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B125%7D%20%2A%20%5Csqrt%5B3%5D%7Bx%5E%7B12%7D%7D%20%20%20%20)
Now, the cube root of 125 is 5, because 5 * 5 * 5 = 125, and that is the definition of a cube root. (What multiplied 3 times by itself is equal to what's under the root)
Now to look at what the cube root of
is.
A cube root can be rewritten as
, same as a square root can be rewritten to
.
So if you take the cube root of x^12, you can change it to:
![(x^{12} )^{1/3}](https://tex.z-dn.net/?f=%20%28x%5E%7B12%7D%20%29%5E%7B1%2F3%7D%20%20)
If you have a case like this, then you can multiply the two powers (in this case 12 and 1/3) to simplify it. 12 * 1/3 = 4, so you get x^4.
Now putting the two together, you get:
5
as your answer.
Hope this helped!
