Answer:
£5.04
Step-by-step explanation:
Let's first find the unit cost.
£3.60/2.5kg = £1.44/kg
To find out how much money 3.5kg of apples costs, we simply need to multiply the unit price by 3.5.
£1.44/kg * 3.5kg = £5.04.
The answer is ( -2 , -1 ) .

116 degrees. It’s simple.
56 is what the low was, but the high was 60 more.
Therefore,
56+60=116
Answer:
Y= 2e^(5t)
Step-by-step explanation:
Taking Laplace of the given differential equation:
s^2+3s-10=0
s^2+5s-2s-10=0
s(s+5)-2(s+5) =0
(s-2) (s+5) =0
s=2, s=-5
Hence, the general solution will be:
Y=Ae^(-2t)+ Be^(5t)………………………………(D)
Put t = 0 in equation (D)
Y (0) =A+B
2 =A+B……………………………………… (i)
Now take derivative of (D) with respect to "t", we get:
Y=-2Ae^(-2t)+5Be^(5t) ....................... (E)
Put t = 0 in equation (E) we get:
Y’ (0) = -2A+5B
10 = -2A+5B ……………………………………(ii)
2(i) + (ii) =>
2A+2B=4 .....................(iii)
-2A+5B=10 .................(iv)
Solving (iii) and (iv)
7B=14
B=2
Now put B=2 in (i)
A=2-2
A=0
By putting the values of A and B in equation (D)
Y= 2e^(5t)
96.5 times 2.54
the answer is 245.11
