the first term in an arithmetic sequence is -1. the fourth term in the sequence is -4. the tenth term in the sequence is -10. which function can be used to find the nth term of the arithmetic sequence?
a) f(n) = 1/2(n + 5) + 2
b) f(n) = n + 4
c) f(n) = -3n + 8
d) f(n) = -n

table 3 represents a direct variation function. : )

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

i think the answer is a p = 78
