Answer:
8/17
General Formulas and Concepts:
<u>Trigonometry</u>
- [Right Triangles Only] cos∅ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use trig to find the ratio.
<u>Step 2: Identify</u>
<em>POV from angle S</em>
Adjacent = 8
Hypotenuse = 17
<u>Step 3: Write</u>
- Substitute [cosine]: cos(s) = 8/17
I got 455 at the 10th week
you just add 15 to your previous total. at 2 weeks she had 335. 3 weeks 350, 4 weeks 365, 5 weeks 380 etc. the 10th week is 455. hope this helps

Answer:
There is no way to actually solve the problem, because it is an expression (no equal sign). But what you can do it simplify the expression. Just add together the like terms, like 3x and -x, and -2 and -3. Doing this, you will get 2x-5.
Answer: 5x^(-1) or 5/x.
Step-by-step explanation: The equation given is (5*x^2)/x^3 and we are supposed to solve it for x = 2. First. we simplify the equation. Since we have x^2 in the numerator and x^3 in the denominator, using the equation a^x/a^y = a^(x - y) we find that we get 5*x^(-1) we can leave it like this or simplify it to 5/x, since negative exponents mean fractions.
