Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
y = P(1 + r/n)^nt
Where
y = the value of the investment 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 invested
From the information given,
P = $4700
r = 4.75% = 4.75/100 = 0.0475
n = 1 because it was compounded once in a year.
Therefore, the exponential function showing the relationship between y and t is
y = 4700(1 + 0.0475/1)^1 × t
y = 4700(1.0475)^t
325.81
It is correct im sure of it

Hello there!
Use the formula for the volume of a sphere:
There is your answer!
:)
X = 8.
2 (8) -4 = 12. LM=12
Let the number of hours Brian travelled = X
Then the number of hours Anne traveled = 5X + 2
Since they together travelled 20 hours, then
X + ( 5X + 2) = 20
X + 5X + 2 = 20
6X + 2 = 20
6X = 20 - 2
6X = 18
X = 18/6
= 3 hours.
So brian travels for a period of 3 hours.
Now the number of hours Anne travelled = 5X +2
= (5 * 3) + 2
= 15 + 2
= 17 hours.
