Step-by-step explanation:
Because the length of ST is calculated using pythagorean theorem:
![{c}^{2} = {a}^{2} + {b}^{2}](https://tex.z-dn.net/?f=%20%7Bc%7D%5E%7B2%7D%20%20%3D%20%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20)
Where the square of the hypotenuse is equal to the sum of squares of the other two sides of a right triangle. In this case, the hypotenuse is ST and the other two sides are distances between S and T over the X and Y axis. Those are easily calculated:
![x = |sx - tx| \\ y = |sy - ty|](https://tex.z-dn.net/?f=x%20%3D%20%20%7Csx%20-%20tx%7C%20%20%5C%5C%20y%20%3D%20%20%7Csy%20-%20ty%7C%20)
Where x is the distance between S and T over X axis and Y distance over Y axis, sx and tx are X coordinates of S and T, sy and ty are Y coordinates of S and T.
Using that formula, you get that y = 17 and x = 8.
Back to the pythagorean theorem, if we put those number in the formula of the pythagorean theorem, we get something like this:
![{c}^{2} = {x}^{2} + {y}^{2} \\ {c}^{2} = {8}^{2} + {17}^{2} = 64 + 289 \\ {c}^{2} = 353 \\ c = \sqrt{353}](https://tex.z-dn.net/?f=%20%7Bc%7D%5E%7B2%7D%20%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%20%20%7By%7D%5E%7B2%7D%20%5C%5C%20%20%7Bc%7D%5E%7B2%7D%20%20%3D%20%20%7B8%7D%5E%7B2%7D%20%20%2B%20%20%7B17%7D%5E%7B2%7D%20%3D%2064%20%2B%20289%20%20%5C%5C%20%20%7Bc%7D%5E%7B2%7D%20%20%3D%20353%20%5C%5C%20c%20%3D%20%20%5Csqrt%7B353%7D%20)
And finally, the correct answer is in fact 353.
Please, post the instructions along with your question, and if possible share the question in symbolic form, not in words.
Do you mean Question #5? By (2) x cube, do you mean 2x^3?
I strongly suggest that you use lots of parentheses ( ) to show how your numbers are grouped, and not to use " x " to denote multiplication (use " * " for that, please.
If only you'll clear this up, I'd be happy to help.
I will assume that your post is 2x^3 - 3(9x-5)^2.
Then 2x^3 - 3(81x - 90x + 25). Does this have any resemblance to what you wanted me to see in your post?
<h3><u>Out of the four options, the letter B is a function.</u></h3>
A function cannot have an x value with two different listed y terms.
B is the only option that does not repeat x terms.
