Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1 + r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
a) From the information given,
P = $1000
r = 4% = 4/100 = 0.04
n = 1 because it was compounded once in a year.
t = 4 years
Therefore,
A = 1000(1 + 0.04/1)^1 × 4
A = 1000(1.04)^4
A = $1170
b) After 18 years, t = 18, therefore
A = 1000(1.04)^18
A = $2026
c) When A = $1500, then
1500 = 1000(1.04)^t
1500/1000 = (1.04)^t
1.5 = (1.04)^t
Taking log of both sides, it becomes
Log 1.5 = tlog(1.04)
0.176 = 0.017t
t = 0.176/0.017
t = 10.35 years
d) When A = $2000, then
2000 = 1000(1.04)^t
2000/1000 = (1.04)^t
2 = (1.04)^t
Taking log of both sides, it becomes
Log 2 = tlog(1.04)
0.301 = 0.017t
t = 0.301/0.017
t = 17.7 years

Answer:
25 is the max (UE) and 2 is the min (LE).
Answer:correct
Step-by-step explanation:
The volume of the concrete block = volume of cuboid - volume of cylinder = 22,476.11 cm³.
<h3>What is the Volume of a Cylinder?</h3>
Volume of cylinder = πr²h, where h is the height of the cylinder and r is the radius.
What if the Volume of a Cuboid?
Volume of a cuboid = length × width × height
Thus:
The volume of the concrete block = volume of cuboid - volume of cylinder
= length × width × height - πr²h
Substitute
= 90 × 15 × 20 - π × 4² × 90
= 27,000 - 4,523.89
= 22,476.11 cm³
Therefore, the volume of the concrete block = volume of cuboid - volume of cylinder = 22,476.11 cm³.
