A homeowner has an octagonal gazebo inside a circular area. Each vertex of the gazebo lies on the circumference of the circular area. Area that is inside the circle, but outside the gazebo, requires mulch. This area is represented by the circular area The square foot of mulch This cost is represented by the function g/m), where m is the area requiring mu gim)-150m Which expression represents the cost of the mulch based on the radius of the cirçle? Unction mix), where x is the length of the radius of the circle in feet The homeowner estimates that he will pay $1.50 per

the answer is a. 1.50(π x^-2/2x^2) i just took the pre-test

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
