<span>The equation for that is

A = P * [ 1 + (r/n) ] ^(nt)

A = amount of money accumulated after n years, including interest.
P = principal amount (the initial amount you borrow or deposit)
r = annual rate of interest (as a decimal)
n = number of times the interest is compounded per year
t = number of years the amount is deposited or borrowed for.

In this question, P = 9700 , r = 0.034, n = 4 , t = 1
</span>
<span>A = 9700 * [ 1 + (0.034 / 4) ] ^ (4 * 1)

= 9700 * ( 1 + 0.0085 )^4

= 9700 * (1.0085)^4

= 9700 * 1.03443596

Solve for the value of w.<br> (w-8)°<br> (2W-1)º
atroni [7]

Answer:

w=57

Step-by-step explanation:

The angles are supplementary because they are adjacent to one another and lies on a straight line

w-8+2w-1=180

Combine like terms

3w-9=180

Subtract 9 on both sides

3w=171

Divide 3 on both sides

w=57
