Answer:
AB = 20 tan55°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan55° = =
=
( multiply both sides by 20 )
20 tan55° = AB

Using the interest formulas, it is found that the values of the investment are given as follows:
- Using simple interest, the value will be of $34,000.
- Using compound interest, the value will be of $144,461.
- Using continuous compounding, the value will be of $148,002.
Simple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:
In which:
- P is the initial amount.
- r is the interest rate, as a decimal.
In this problem, we have that the parameters are as follows:
P = 9000, r = 0.07, t = 40.
Hence:
n is the number of compounding, for quarterly n = 4, then:
Hence:

Answer: 80%
Step-by-step explanation:
Since we have given that
Number of erasers sold in May = 80
Number of erasers sold in June = 16
Decrement in 1 month gap is given by
16-80=-64
So, Percentage of change in erasers sold from May to June is given by
× 100
= -80% (Decreased 80%)
