There are 24 (2x8+2x4) posts around the pool with 4 overlaps, therefore, there are 20 posts in total.
Among the 8 posts along one side, there are 7 gaps in between them. Hence, the length is 2x7=14yards
Among the 4 posts on the other side, there are 3 gaps in between them. Hence, the width is 2x3=6 yards

Martin was going to the market to buy apples. The price for apples is $3.50 times the number of apples bought plus one-dollar ta
AnnZ [28]

Answer:

Polynomial Function: 3.5n + 1

Total Price of the Apples: $32.50

Step-by-step explanation:

The polynomial function is 3.5n + 1:

The 3.5n comes from the $3.50 it costs to buy an apple, and the n comes from the amount of apples bought. The 1 then comes from the tax that is added onto the price.

The total price of the apples:

3.5n + 1 ; n = 3^3 = 9

(3.5 x 9) + 1

31.5 + 1

32.5

$32.50

If the 1st and 10th terms of geometric sequence are 4 and 100. Fine the nth term of the sequence
gulaghasi [49]
A(n)=ar^(n-1)  so

100=4r^9

25=r^9

ln25=9lnr

ln25/9=lnr

r=e^(ln25/9)

a(n)=4e^((n-1)(ln25/9)  if you wanted an approximation...

a(n)=4(1.43^(n-1))
