For this case it is observed that the "zeros" are to the left of the expression, therefore the exponent, to be expressed in scientific notation, will be negative. That is to say:

This means that by running the decimal 6 spaces to the left we will get the initial expression.

Answer:
a ≈ 19.45
Step-by-step explanation:
<u><em>Law of Cosines</em></u>
a=c2+b2﹣2cbcosγ
=112+132﹣2·11·13·cos(108°)
≈19.45196
The amount of books Matt had at the beginning (5) is a constant that does not change, thus nothing will be multiplied by that number. This eliminates options A and C, which both demonstrate 5 as being multiplied by the amount, x, of weeks.
As for the other two equations, which one makes sense for this problem, which models an increase of books over time? The equation with addition.
Answer:
<span>D. y = 5 + x
This problem shows the amount of library books Matt will have after any random amount of weeks he checked out one book, combined with the 5 he had before starting this pattern.</span>
Answer: a. 450
b. 7950
Step-by-step explanation:
If Cheryl earns 6% interest during the 6 years she will have
(7500*6)/100=450
450 is the interest that she received
her new balance will be
7500+450=7950
1/2x2/4=1/4
2/4x3/6=1/4
3/6x1/2=1/4
