The total profit p (in millions of dollars) earned by a company from 1995 to 2004 can be modeled by p=3500+500t/98-t where t is the number of years since 1995. the number n (in hundreds of thousands) of units sold can be modeled by n=(t+7)(3000-20t)/490-5t whete t is the number of years since 1995. write a model that gives the profit earned per unit per year. then approximate the profit per unit inasap

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
