Answer:

see explanation

Step-by-step explanation:

To calculate the first 3 terms substitute n = 1, 2, 3 into the n th term formula

(a)

8 - 1 = 7

8 - 2 = 6

8 - 3 = 5

The first 3 terms are 7, 6, 5

Answer:

39 ft

Step-by-step explanation:

Using the description as a guideline I have drawn out the situation (badly drawn) as seen in the picture below. From the picture, we see that we need to find x which is the length of one of the ropes. Once we have this length we simply multiply it by 3 to find out how much rope we need altogether. Since this is the diagonal of a triangle we can use the Pythagorean theorem to solve for x.

Pythagorean theorem: $a^{2} +b^{2} = c^{2}$ .... which a and b are the two sides while x is the diagonal.

$5^{2} +12^{2} = x^{2}$

$25 + 144 = x^{2}$

$169 = x^{2}$ ... now we square root both sides

$13 = x$

Now that we have the length of one of the ropes we simply multiply this by 3 to find the total amount of rope needed.

13 * 3 = 39 ft
