Suppose that the revenue realized on the sale of a company’s product can be modeled by the function  r(x)=600x-0.3x^2, where  x  is the number of units sold and  r(x)  is given in dollars. what is the value of  r(7)? what does this value mean in the context of this problem

Which point lies on a circle with a radius of 5 units and center at p(6, 1)?

3women sell hats at a craft fair weekly. the money they make at the fair is split into categories. 9% goes to pay taxes. $55 goes to pay rent for the space they sell in. the rest is split between the women. if the group make $706 at the fair, how much does each women get paid once the money is divided

Given the equation    = 5, solve for x and identify if it is an extraneous solution
