A local carpet cleaning company charges $11.25 for each room plus a reservation fee of $9. They clean a maximum of 5 rooms. Also, they have the policy that once a reservation is made, if you cancel, the reservation fee is non-refundable and they only clean full rooms not partial rooms. Let C represent the total cost from the carpet cleaning company and n represent the number of rooms cleaned. Note: Round your answers to two decimal places as needed. You may need to use set notation for your domain and range { }. Practical Range:

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.

Write an equation for the function that includes the points (1,4/5) and (2,2/3)

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle? a) (x + 5)2 + (y + 3)2 = 18 (x + 5)2 + (y + 3)2 = 3.72 (x - 5)2 + (y - 3)2 = 18 d) (x - 5)2 + (y - 3)2 = 32
