I think I have part A but I'm stuck on B and C (a) The coordinate (-1,2) defines the centre of a circle.

The coordinate (9, -22) lies on the circumference of this circle

Find the equation for this circle.

(b) Find the tangent to the circle at the point (9, -22).

(c) Find the area of the triangle made with your tangent and the axis.

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
