Answer:
Step-by-step explanation:
The formula for the accrued amount from compound interest is
1. Amount in account on 1 Jan 2015
(a) Data:
a = £23 517.60
r = 2.5 %
n = 1
t = 1 yr
(b) Calculations:
r = 0.025
The amount that gathered interest was £22 944.00 but, before the interest started accruing, Carol had withdrawn £1000 from the account.
She must have had £23 944 in her account on 1 Jan 2015.
(2) Amount originally invested
(a) Data
A = £23 944.00
3. Summary
1 Jan 2014 P = £23 360.00
1 Jan 2015 A = 23 944.00
Withdrawal = <u> -1 000.00 </u>
P = 22 944.00
1 Jan 2016 A = £23 517.60
is conservative if we can find a scalar function such that
. This would require
Integrating both sides of the first equation wrt gives
Differentiating both sides of this wrt gives
but we assumed was a function of
and
, independent of
. So there is no such
and
is not conservative.
To find the work, first parameterize the path (call it ) by
for . Then
and the work is given by the line integral,
