<h3>
Answer: $2,835.56 (Choice A)</h3>
===========================================
Work Shown:
A = P(1+r/n)^(n*t)
A = 2500*(1+0.065/1)^(1*2)
A = 2,835.5625
A = 2,835.56
------------
In the compound interest formula above, I used
- P = 2500 = deposit amount
- r = 0.065 = decimal form of 6.5% interest
- n = 1 = compounding frequency of 1 time per year (annually)
- t = 2 = number of years
I think it C (I don't really remember but I learned it before)
Answer:
32.78
Step-by-step explanation:
Assuming that we have two right triangles joined together, with one having adjacent side a, with a side of 12 ft opposite reference angle 30°, and the other one having adjacent side b, with a side of 12 ft opposite reference angle 45°. Thus, a + b = length of AC.
Let's find a and b.
Finding a:
Reference angle = 30°
Opp = 12 ft
Adj = a
Using trigonometric ratio formula, we have:
tan(30) = 12/a
Multiply both sides by a
a*tan(30) = 12
Divide both sides by tan(30)
a = 12/tan(30)
a = 20.78 (nearest hundredth)
Finding b:
Reference angle = 45°
Opp = 12 ft
Adj = b
Using trigonometric ratio formula, we have:
tan(45) = 12/b
Multiply both sides by a
b*tan(45) = 12
Divide both sides by tan(45)
b = 12/tan(45)
a = 12
Length of AC = 20.78 + 12 = 32.78
There isn't enough info to answer this, sorry.
Answer:
1,497.06
Step-by-step explanation:
1,397.26 in gas, cuz 52 weeks in a year (sorry if I multiplied wrong), and $99.80 for oil, cuz 12 months in a year. So the total is 1,497.06
