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
After moving all the terms to the right of the equation and solving you would get A = -36/49. Hope this helps!
6/10 rounding to the nearest half would be 1, not 0.
Reason for this: Here is a number line to help you!
|----|----|
Left line = 0
Middle line = 1/2
Right line = 1
Here is another rule!
0/10, 1/10, 2/10, 3/10, 4/10 = rounded to the nearest half would be 0
5/10, 6/10, 7/10, 8/10, 9/10, 10/10 = rounded to the nearest half would be 1.
So 6/10 rounded to the nearest half is 1.
Hope this helped!

Answer:
Step-by-step explanation:
To find the area subtract the area of the semicircle from the area of the rectangle.
Although the line isn’t there, if you imagine there is one, then you will see that you form a rectangle which is the same line as the semicircle’s diameter.
The area of rectangle is:
⇒ 
⇒ 
⇒ 
The area of the semicircle;
⇒ 
⇒ 
*Note here that the radius is half the diameter, so it is 7cm, not 14cm
⇒ 
Finally subtract the two areas;
⇒ 
⇒
