Given the formula for an arithmetic sequence f(7) = f(6) + 4 written using a recursive formula, write the sequence using an arit
natita [175]

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\\

Find the surface area of the cylinder give your answer in terms of pi. The radius is 4mm and the height is 5mm
Komok [63]
The surface area of a cylinder is the area of the bases plus the area of the side, or SA = 2*A₁ + A₂

Since the area of a circle is \pi r^{2},
SA = 2*(\pi r^{2}) + A₂

Since the area of the side is height * the circumference of the circle or A₂ = h * 2 \pi r, then SA must be;

SA = 2* \pi (r ^{2} )+h*2 \pi r
SA = 2* \pi (4 ^{2} )+5*2 \pi (4)
SA = 32* \pi+80 \pi
SA ≈ <span>351.858377202</span>
