Answer:
19.8%
Step-by-step explanation:
We have the following formula for continuous compound interest:
A = P * e ^ (i * t)
Where:
A is the final value
P is the initial investment
i is the interest rate in decimal
t is time.
The time can be calculated as follows:
25 - 18 = 7
That is, the time corresponds to 7 years. In addition, A is 20,000 for A and P would be 5,000, we replace:
20000 = 5000 * e ^ (7 * i)
20000/5000 = e ^ (7 * i)
e ^ (7 * i) = 4
ln e ^ (7 * i) = ln 4
7 * i = ln 4
i = (ln 4) / 7
i = 0.198
Which means that the rounded percentage will be 19.8% per year

Answer:
9/4 yards
Step-by-step explanation:
A poster is a rectangle.
Area of rectangle = Length × Width
Given:
Area = 3/4 yd
Length = 1/3 yd
Substitute the given values to the equation.
3/4 = 1/3 × w
3/4 = 1/3w
3/4 ÷ 1/3 = w
3/4 × 3/1 = w
9/4 = w
