Stacy put a fence around a rectangular flower bed with a length of 18ft and a width of 4.5 ft. Next, he enclosed a square flower
1 answer:
Answer:
36 feet
Step-by-step explanation:
Let us first find the area of the of the flower bed. It is a rectangle, so:
A = 18 * 4.5 = 81 square feet
The square flower bed has the same area, therefore, the length of the sides of the flower bed can be gotten. The area of a square is:
L = 9 feet
Next, we need to find the perimeter of the square flower bed:
P = 4L
=> P = 4 * 9 = 36 feet
He needed 36 feet of fence to enclose the entire square flower bed.

<u>Answer-</u>
<em>The total amount you would have earned over the first 16 years is </em><em>$90047.20</em>
<u>Solution-</u>
The exponential function that would given the growth is,
Where,
P' = Future value,
P = Current value = $50000
r = rate of change = 4% = 0.04
t = time = 15 year (not 16 because the the increment occurs at year end and we want to get the value at the beginning of 16th year)
Putting the values,
Therefore, the total amount you would have earned over the first 16 years is $90047.20
