Answer: the interest rate is 6%
Step-by-step explanation:
The formula for continuously compounded interest is
A = P x e (r x t)
Where
A represents the future value of the investment after t years.
P represents the present value or initial amount invested
r represents the interest rate
t represents the time in years for which the investment was made.
e is the mathematical constant approximated as 2.7183.
From the information given,
A = $4482
P = 1000
t = 25 years
Therefore,
4482 = 1000 x 2.7183^(r x 25)
4482/1000 = 2.7183^25r
4.482 = 2.7183^25r
Taking ln of both sides, it becomes
Ln 4.482 = 25rLn2.7183
1.5 = 25r
r = 1.5/25 = 0.06
r = 0.06 × 100 = 6%
40 can be gotten by multiplying 10 & 4
28 can be found by adding 10 + 10 + 4 + 4
so the side lengths are 4 & 10
The answer is (4x-5)(5x^2+1)
W^2-10w-10
Step-by-step explanation:
D=w^2-7
C=3+10w
D-C
(W^2-7)-(3+10w)
W^2-7-3-10w
Answer:9:00 pm
Step-by-step explanation:
Start time: 7:20pm
Duration of movie: 1 hour 40minutes
End time= 7:20 + 1:40
= 8:60 = 9:00pm
60 minutes make 1 hour.
