F(n)=5.(-2)n-1<br>Complete the recursive formula of f(n).

Alex73 [517]

Answer:

a(n) = $(-2)(a_{n-1})$

$a_{1}=5$

Step-by-step explanation:

The given expression is in the form of the explicit formula of a geometric sequence.

f(n) = $a(r)^{n-1}$

Where 'a' = First term of the sequence

r = common ratio

Recursive formula of a geometric sequence is,

a(n) = $(a_{n-1}).(r)^{n-1}$

a(n) = $(-2)(a_{n-1})$

Where, $a_{1}=5$

So the recursive formula will be a(n) = $(-2)(a_{n-1})$

What is the total surface area of this square pyramid?

slamgirl [31]

Answer:

The total surface area of this square pyramid is $297\ mm^{2}$

Step-by-step explanation:

we know that

The surface area of a square pyramid is equal to

$SA=b^{2} +4[\frac{1}{2}(b)(h)]$

we have

$b=9\ mm$ ----> the length side of the square base

$h=12\ mm$ ----> the height of the triangular faces

substitute the values

$SA=9^{2} +4[\frac{1}{2}(9)(12)]=297\ mm^{2}$
