B,C

Step-by-step explanation:

So all you have to do is use the pythagorean theorem to solve this (a²+b²=c²).

Plug in the two shorter sides for a and b and the long side for c. If both sides equal the same thing then it will make a right triangle.

A) 5²+6²=9²

25+36=81

61≠81

B) 0.25+1.44=1.69

C)49+576=625

D) 100+256≠361

E)1+4≠9

h(x) * s(x) = 200(1.05)^(x - 1)

Step-by-step explanation:

Our interest equation is s(x) = (1.05)^(x - 1). This is actually a part of a bigger formula for calculating the amount of money accumulated including interest:

A = P(1 + r)^n, where A is the total, P is the principal amount (initial amount), r is the interest rate, and n is the time

Here, we technically already have the (1 + r)^n part; it's just (1.05)^(x - 1). The principle, though, will actually be the 200 because she starts out at $200.

Thus, to combine these, we simply multiply them together to get:

h(x) * s(x) = 200(1.05)^(x - 1)
