Answer:
£15.7
Step-by-step explanation:
32 cans x 50P = 1600p
1600p to Pounds = £26.66 (1600 divided by 60)
Remaining cans = 18 (50 - 32)
18 cans x 20p = 360p
360p to Pounds = £6 (360 divided by 60)
£26.66 + £6 = £32.66
£32.66 (Profit) - £17 (Cost of cans) = £15.66
15.66 to 3SF = 15.7
V=448 in^3
l=8 in
w=12
h=?
V=l•w•h/3
448=8•12•h/3 multiply both sides by 3
3•448=96•h
1344=96•h
h=1344/96
h=14 in
V=l•w•h/3
h=4in
l=3in
w=2.5 in
V=?
V=4•3•2.5/3
V=30/3
V=10 in^3
Answer:
Of(7) = f(1) + 24
Step-by-step explanation:
Since this Arithmetic Sequence can be written recursively as a function, then we can write the whole sequence, by adding the common difference to the previous function. So writing it as an Arithmetic formula is (placing an example, with a common difference of 4 units):
![\left.\begin{matrix}n &1&2&3&4&5&6 &7\\f(n)&2&6&10 & 14&18&22&26 \end{matrix}\right|\\f(n)=f(n-1)+d\:\: (Recursive \: Formula)\Rightarrow a_{n}=a_{n-1}+4\: \: \: (Arithmetic\: Formula)\\Of(7)=f(1)+6*4\Rightarrow a_{7}=a_{1}+(7-1)4\Rightarrow a_{7}=a_{1}+24\\](https://tex.z-dn.net/?f=%5Cleft.%5Cbegin%7Bmatrix%7Dn%20%261%262%263%264%265%266%20%267%5C%5Cf%28n%29%262%266%2610%20%26%2014%2618%2622%2626%20%5Cend%7Bmatrix%7D%5Cright%7C%5C%5Cf%28n%29%3Df%28n-1%29%2Bd%5C%3A%5C%3A%20%28Recursive%20%5C%3A%20Formula%29%5CRightarrow%20a_%7Bn%7D%3Da_%7Bn-1%7D%2B4%5C%3A%20%5C%3A%20%5C%3A%20%28Arithmetic%5C%3A%20Formula%29%5C%5COf%287%29%3Df%281%29%2B6%2A4%5CRightarrow%20a_%7B7%7D%3Da_%7B1%7D%2B%287-1%294%5CRightarrow%20a_%7B7%7D%3Da_%7B1%7D%2B24%5C%5C)
