28 x 2 = 56 half dollar coins
<u>Answer:</u>
The correct answer option is: 19, 13, 3, -11, -29.
<u>Step-by-step explanation:</u>
We are given the following explicit formula for an arithmetic sequence:

So to find the first five terms of this sequence, we will substitute the values of
(num here in the given formula:





Therefore, the first five terms of the sequence defined by the explicit formula
are 19, 13, 3, -11, -29.

Answer: 60 in
Step-by-step explanation:
Hi, to answer this question, first we have to calculate the diameter of one flotation device:
Circumference of a circle C = (3.14) (diameter)
Replacing with the values given:
62.8 =3.14 d
Solving for d (diameter)
62.8 /3.14 =d
20in = d
Now, since the three flotation devices are identical, we simply have to multiply the diameter of one device by 3 , to obtain length of the flotation devices lined up.
20x3 =60 in
