Answer: the value of her investment after 4 years is £8934.3
Step-by-step explanation:
The formula for determining compound interest 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 invested.
t represents the duration of the investment in years.
From the information given,
P = 8000
r = 2.8% = 2.8/100 = 0.028
n = 1 because it was compounded once in a year.
t = 4 years
Therefore,
A = 8000(1+0.028/1)^1 × 4
A = 8000(1+0.028)^4
A = 8000(1.028)^4
A = £8934.3 to the the nearest penny

Put the coordinates of the point in for x, y, and z and see what the new constant is.
Your plane is

Answer:
278.773622 or 300 if rounded
Step-by-step explanation:
The area of a circle is:
π (Pi) times the Radius squared:
A = π r2
or, when you know the Diameter:
A = (π/4) × D2
or, when you know the Circumference:
A = C2 / 4π
I’m pretty sure the answer is B.
