If two chords intersect each other inside a circle, the products of their segments are equal.
18(n+1) = 9(n+7)
18n + 18 = 9n + 63
18n - 9n = 63 - 18
9n = 45
n = 45/9
n = 5
57 cubic thingie so the last one

Step-by-step explanation:
![slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{3-(-2)}{9-2}\\\\=\frac{3+2}{7}\\\\=\frac{5}{7}](https://tex.z-dn.net/?f=slope%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C%3D%5Cfrac%7B3-%28-2%29%7D%7B9-2%7D%5C%5C%5C%5C%3D%5Cfrac%7B3%2B2%7D%7B7%7D%5C%5C%5C%5C%3D%5Cfrac%7B5%7D%7B7%7D)
Answer:
C. III only
Step-by-step explanation:
a quadratic function means that as the maximum power in its arguments it is squaring 1 or more items.
so, let's look at the tables.
table I shows the powers of 2. y = 2^x
2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
so, it is not saying anything in general.
table II shows an "identity" equation. y = x
0 = 0
1 = 1
2 = 2
3 = 3
this does not square anything.
table III shows then finally a square equation. y = x^2
0^2 = 0
1^2 = 1
2^2 ≈ 4
3^2 = 9
hurray !
