92 ft i think. please correct me if i’m wrong.
which sequences are arithmetic? check all that apply. –8.6, –5.0, –1.4, 2.2, 5.8, … 2, –2.2, 2.42, –2.662, 2.9282, … 5, 1, –3, –

In an arithmetic sequence, the next term is found by adding a constant term to each number to arrive at the next number. The common difference can be found by subtracting the first term from the second term.
-8.6, -5.0, -1.4, 2.2, 5.8....the common difference here is 3.6
-8.6 + 3.6 = -5.0
-5.0 + 3.6 = -1.4
1.4 + 3.6 = 2.2
2.2 + 3.6 = 5.8
so this IS an arithmetic sequence.
2,-2.2, 2.42, -2.662, 2.9282...there is no common difference..so this is not an arithmetic sequence
5,1,-3,-7,-11....common difference is -4
5 + (-4) = 1
1 + (-4) = -3
-3 + (-4) = -7
-7 + (-4) = -11
this IS an arithmetic sequence
-3,3,9,15,21...common difference is 6
-3 + 6 = 3
3 + 6 = 9
9 + 6 = 15
15 + 6 = 21
this IS an arithmetic sequence
-6.2, -3.1, -1.55, -0.775, -0.3875...this is not an arithmetic sequence
Answer: a) $26.55/year
b) $64.13/year
Step-by-step explanation:
a) <u>$7.64</u> . <u>1 ft³</u> . <u>50 gal</u> . <u>1 load </u> . <u>52 week</u> = $<u>26.55</u>
100 ft³ 7.48 gal 1 load 1 week 1 year year
The total cost per year is $26.55
b)<u>$7.64</u> . <u>1 ft³</u> . <u>17.2 gal</u> . <u>1 shower </u> . <u>365 days</u> = <u>$64.13</u>
100 ft³ 7.48 gal 1 shower 1 day 1 year year
The total cost per year is $64.13
