Answer:
Step-by-step explanation:
+2*k*pi is for the periodicity (if you turn 360° you get back to the same point)
Y=125,000 (1+.035)^10
Y=125,000 (1.035)^10
Y=125,000 (1.410598716) or 125,000 (1.41)
Y= $176324.85 or $176250
If your looking looking for the y-intercept its y=-3
I don't really understand what you are asking though....
Given:
Cost of dishwasher : 315 before sales tax
sales tax : 9.22%
Total cost = 315 * 1.0922 = 344.043
Average of 10 uses per week for the next 6 years before replacing it.
There are 52 weeks in a year.
10 uses per week * 52 weeks per year * 6 years = 3120 average uses
cost for water = 0.09 ; cost for electricity = 0.13 ; total cost per use = 0.22
0.22 * 3120 = 686.40 cost of use
purchase cost = 344.043
cost of use = <u>686.40</u>
lifetime cost 1,030.443
