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
The number is assumed to be x
x of 40% = 56
x * (40/100) = 56
x = 5600 / 40
x = 140
5.242 to the nearest tenth is 5.2.
6.537 to the nearest tenth is 6.5.
11.382 to the nearest tenth is 11.4.

Answer:
area(rectangle) = Length * width
8w + 18 = 2 * w
