blagie [28]

Answer:

The larges perimeter she can make becomes is 96 ft

Step-by-step explanation:

Here we note that the available brick is 47 ft²

Therefore, she has 47 square cement blocks

Let the length of the sides of the rectangle with the most perimeter be x and y

Then 2·x + 2·y = 47 which is not possible because 47 is a prime number

Hence we have the possible sides of the rectangle is a single line of square blocks such that

x × y  = 47 ft² where y = 1 hence x = 47

The larges perimeter she can make becomes, 2 × (1 + 47) = 96 ft.

Does the following infinite series converge or diverge?
Vladimir79 [104]
The nth term is (presuming the denominator on the first is a typo)

-\dfrac{n}{(-3)^n}

The ratio of successive terms is

\dfrac{ \frac{n+1}{(-3)^(n+1)}}{\frac{n}{(-3)^n}} = \frac{n+1}{-3n}

The limit is -1/3, absolute value less than 1, so the series converges.  It has a sum -- that's what converges means.
