The diagram is called the venn diagram
Two quick changes before diving into action:
First of all, we can factor the 100 out of the sum:
Secondly, we can see that the index k starts from 1, but the exponent is k-1. This means that when k=1, the exponent is actually 0. When k=2, the exponent is actually 1, and so on. So, we can rewrite the sum as
Now, let's focus on the sum. First of all, it converges, because every sum like
converges if and only if , which is the case because
Also, in this case we have
so in your case you have
and let's not forget the 100 we factored at the beginning!
Answer:
$1346.40
Step-by-step explanation:
Find the volume of the pool first:
volume = cubiod + triangular prism
volume = (8*6*8) + (8*6*6)/2
volume = 528 cubic feet
price = price per cubic foot * cubic feet
price = $2.55 * 528 cubic feet
price = $1346.40
