Answer:
Step-by-step explanation:
Yasmina:
5.25 x 5 = 26.25 per week
5.25 x 20 = 105 per month
5.25 x 260 = 1365 per year
Camila:
9.75 x 35 = $ 341.25 earnings per week
341.25 x 0.20 = 68.25 saves per week
9.75x35x 4= 1365 earnings per month
1365 x 0.20 = 273 saves per month
9.75 x 35 x 52 = 17745 earnings per year
17745 x 0.20 = 3549 saves per year
Answer:
f(n)=f(n-1)+f(n-2)
f(1)=1x
f(2)=1x
Step-by-step explanation:
This is the fibonacci sequence with each term times x.
Notice, you are adding the previous two terms to get the third term per consecutive triples of the sequence.
That is:
1x+1x=2x
1x+2x=3x
2x+3x=5x
3x+5x=8x
So since we need the two terms before the third per each consecutive triple in the sequence, our recursive definition must include two terms of the sequence. People normally go with the first two.
f(1)=1x since first term of f is 1x
f(2)=1x since second term of f is 1x
Yes, I'm naming the sequence f.
So I said a third term in a consecutive triple of the sequence is equal to the sum of it's two prior terms. Example, f(3)=f(2)+f(1) and f(4)=f(3)+f(2) and so on...
Note, the term before the nth term is the (n-1)th term and the term before the (n-1)th term is the (n-2)th term. Just like before the 15th term you have the (15-1)th term and before that one you have the (15-2)th term. That example simplified means before the 15th term you have the 14th and then the 13th.
So in general f(n)=f(n-1)+f(n-2).
So the full recursive definition is:
f(n)=f(n-1)+f(n-2)
f(1)=1x
f(2)=1x
Answer: 
Step-by-step explanation:
Sine uses the ratio,
so we can plug in the information we know. since there is no current value for the opposite side of angle A, we can just use a variable to replace it.

You can't reduce this any further because there is an unknown variable.
