Hi there
The formula is
A=p (1+r)^t
A future value
P present value 75
R interest rate 0.05
T time
After 1 year the balance is
A=75×(1+0.05)
A=78.75
After 2 years
A=75×(1+0.05)^(2)
A=82.69
After 5 years
A=75×(1+0.05)^(5)
A=95.72
After 20 years
A=75×(1+0.05)^(20)
A=198.99 round
A=199
Hope it helps
Answer: the height in inches, of the pile after 3 weeks is 34 11/12 inches
Step-by-step explanation:
Each consecutive week for the next 5 weeks the height of pile increase by 8 7/12 inches. Converting 8 7/12 inches to improper fraction, it becomes 103/12 inches. The height is increasing in an arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 17 3/4= 71/4 inches
d = 103/12 inches
n = 3 weeks
the height in inches, of the pile after 3 weeks, T3. Therefore,
T3 = 71/4 + (3 - 1)103/12
T3 = 71/4 + 2 × 103/12 = 71/4 + 103/6
T3 = 419/12 inches = 34 11/12 inches
