Floor(0) -3 = -3 . . . . . only the left-side graphs have this point
floor(0.1) -3 = -3 . . . . only the lower-left graph has this point.
The lower-left selection is appropriate.
30 for number 2. If the problem is what's the point where the line is its 30
Answer:
(a) an = 18 +3(n -1)
(b) row 35
Step-by-step explanation:
(a) The general term (an) of an arithmetic sequence can be expressed in terms of the first term (a1) and the common difference (d) as ...
an = a1 +d(n -1)
The given sequence has a1 = 18 and d = 3, so the explicit formula is ...
an = 18 + 3(n -1)
__
(b) We want to find n such that an = 120.
120 = 18 + 3(n -1)
40 = 6 + n - 1 . . . . . . . divide by 3
35 = n . . . . . . . . . . . . . subtract 5
Row 35 has 120 seats.
B. No, because it's less than the deduction she would get from itemizing.-APEX
