Sales A soft-drink vendor at a popular beach analyzes his sales records and finds that if he sells x cans of soda pop in
one day, his profit (in dollars) is given by
P(x) = -0.001x2 + 3x 1800
What is his maximum profit per day, and how many cans
must he sell for maximum profit?

3/6   and 9/18

step-by-step explanation:

im not sure

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
