Tutorial Exercise A real estate office handles a 70-unit apartment complex. When the rent is $520 per month, all units are occupied. For each $40 increase in rent, however, an average of one unit becomes vacant. Each occupied unit requires an average of $60 per month for service and repairs. What rent should be charged to obtain a maximum profit?
Four-legged animals run with two different types of motion: trotting and galloping. An animal that is trotting has at least one foot on the ground at all times, whereas an animal that is galloping has all four feet off the ground at some point in its stride. The number of strides per minute at which an animal breaks from a trot to a gallop depends on the weight of the animal. Use the table and the method of this example to find an equation that relates an animal's weight x (in pounds) and its lowest galloping speed y (in strides per minute). Weight, x Galloping Speed, y Need Help? Submit Answer 25 192.5 + Take the natural logarithm of each coordinate to obtain points of the form (In x, In y). (Round your answers to three decimal places.)

Ella has a cell phone plan. She tells you that after 8 months, she has paid a total of $760 and after 10 months, she has paid a total of $840. She does not remember the cost of the phone. Let's start by converting these to coordinates (m, C) where the inputs, m, are the number of months since Ella bought the phone, and the outputs, C, represent the total cost that Ella has paid after that many months. Coordinate for eight months: Coordinate for ten months:
How many rows of A contain a pivot position? Does the equation Ax = b have a solution for each b in R*? 2 4 - 1 6. -2 -2 - 2 A = - 4 - 12 2 5 - 10 How many rows of A contain a pivot position? has rows which contain a pivot position. Does the equation Ax = b have a solution for each b in R*? O A. Yes, because the reduced echelon form of A does not have a row of the form 0 b with b nonzero. О В. No, because each b in R* is a linear combination of the columns of A. C. Yes, because the columns of A do not span R*. O D. No, because A does not have a pivot position in every row.
Read the following word problem, then choose which linear equation models the problem. One number is 10 times another number. Their difference is 54. Find the numbers. O x(x) – 10 = 54 O 10x-x= 54 O 10x(x) = 54 %3D O 10x + x = 54

The below figure shows the flow of traffic near a city’s Civic Centre during the rush hours on a typical weekday. Each road can handle a maximum of 1000 cars/ hour without causing congestion. The flow of traffic is controlled by traffic lights at each of the five intersections. a. Formulate a system of linear equations describing the traffic flow.b. Solve the system devised in part (a) ensuring no congestion.c. Suppose 7th avenue between 3rd and 4th streets is soon to be closed for road repairs. Find one possible flow pattern that will result in a smooth flow of traffic.
