Answer:
6, 12, 18, 24, 30
Step-by-step explanation:
1+2+3+4+5 = 15
90 divided by 15 is 6
6x1 = 6
6x1 = 12
6x1 = 18
6x1 = 24
6x1 = 30
a is the answerStep-by-step explanation:
Using the fact that cos is 2π-periodic, we have
That is, for any and integer .
We get 2 solutions in the interval [0, 2π] for and ,
percent* base = amount
.2 * x = 1.80
x = 1.80/.2
x= $9
