Answer:
n = 1, A = $2,191.12
n = 2, A = $2,208.04
n = 4, A = $2216.71
n = 12, A = $2222.58
n = 365, A = $2225.44
Compound continuously, A = $2,225.54
Step-by-step explanation:
We are given the following in the question:
P = $1000
r = 4% = 0.04
t = 20 years
Formula:
The compound interest is given by
where P is the principal, r is the interest rate, t is the time, n is the nature of compound interest and A is the final amount.
For n = 1
For n = 2
For n = 4
For n = 12
For n = 365
Compounded continuously:
Answer:
The mass of the piece of granite with volume of 75 cm^3 is 202.5 grams.
Step-by-step explanation:
Let
m = the mass of a piece of granite whose volume is: 40 + 35 = 75 cm^3 (greater by 35 cm^3)
Since Density = Mass / Volume and we are talking about pieces of the same material (same density) we can write:
m/75 = 108/40
m = 202.5 g
I think the answer is 16.5 sorry if its not right
