Four different sets of objects contain 2,5,6, and 7 objects, respectively. How many unique combinations can be formed by picking
Ilia_Sergeevich [38]
There are 2 choices for the first set, and 5 choices for the second set. Each of the 2 choices from the first set can be combined with each of the 5 choices from the second set. Therefore there are 2 times 5 combinations from the first and second sets. Continuing this reasoning, the total number of unique combinations of one object from each set is:
2\times5\times\times6\times7=420\ combinations

He cost, in millions of dollars, of building a three-story high school in new york state was estimated to be c(x) = 2.1 + 0.12x
ratelena [41]

Given cost function is

c(x) = 2.1 + 0.12x - 0.0001x^2 (20 ≤ x ≤ 400)

where x is the number of thousands of square feet

total revenue will be $0.2 million dollars per thousand square feet

Revenue is 0.2 millions per thousand square feet. we know x is the number of thousand of square feet

So R(x) = 0.2x

We know Profit = Revenue - Cost

P(x) = R(x) - C(x)

P(x) = 0.2x - (2.1 + 0.12x - 0.0001x^2)

P(x) = 0.2x - 2.1 - 0.12x + 0.0001x^2)

combine like terms

P(x) =-2.1 + 0.08x + 0.0001x^2

Profit function is

P(x) =0.0001x^2 + 0.08x - 2.1
