Given the arithmetic sequence an = −4 + 4(n − 1), what is the domain for n?

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.

if the rectangular pool has a area of 192 square ft. and length of 15 ft. you must divide 15 into 192. 192 ÷ 15 = about 13 ft.
