i don't know the answer for partc.
is answer a and b correct
a) and b) are correct
sub in the given values
20 = 72/6 + k
20 = 12 + k
k = 8
so now you know
s= 72/(t+2) + 8
when t = 4/5
s = 72/4.5 + 8 = 24
Part (a) is correct, and (b) is correct to 2 decimal places.
For part (c), you can make use of the approximation formula
f(t0+h)=f(t0)+h*f'(t0) approximately, and when h is relatively small.
Check by initial conditions:
substitute in s(t) to get
So approximation above is reasonably accurate.
