- Use a system of linear equation to find the parabola y=ax2+bx+c that passes through the points (1,2), (0,1) and (2,6)arrow_forwardWhat is interpolation when using a linear model?arrow_forwardTemperature Conversion Write a linear equation that expresses the relationship between the temperature in degrees Celsius C and degrees Fahrenheit F. Use the fact that water freezes at 0C32F and boils at 100C212F.arrow_forward
- Linearize the following non-linear model. (i) y = a,x* (ii) y = a · b, +xarrow_forwardSketch the graph of the system.arrow_forwardThe picture attached represents the traffic entering and leaving a "roundabout" road junction. Such junctions are very common in Europe. Construct a system of equations that describes the flow of traffic along the various branches. What is the minimum flow possible along the branch BC? What are the other flows at that time? (units are vehicles per hour.)arrow_forward
- Consider the linear system : -11 = = [] 83], -2 -3 6 y(0) = [9] 2 Solve this IVP and enter the formulas for the component functions below. x(t) = y(t) = Question Help: Message instructor Submit Question = y'arrow_forward3. Bob, who is 2.2 m tall, is standing a distance of 15 m from a flagpole as shown below. From his point of view, the angle of view between the top and bottom of the pole is 32°. How tall is the flagpole to the nearest hundredth of a metre? [5] В 32° 2.2 m 15 m 3/4 THINKING: 4. Create two linear equations and a sketch of a linear system where both equations are negative (negative slopes) •..arrow_forwardA ball is thrown straight upward. The graph shows the ball's height, s(t), in feet, after t seconds. s(t) 60 48 50 40 (1,40) 30 (3, 24) 20 10 1 Time (seconds) 2 3 4 5 a. Find the quadratic function s(t) = at? + bt + c whose graph passes through the three points labeled on the graph. Solve the system of linear equations involving a, b, and c using matrices. b. Find and interpret s(3.5). Identify your solution as a point on the graph shown. Height above Ground (feet)arrow_forward
- Customers arrive at the ticket counter of a local movie theater at a rate of 240 persons per hour, at 5.30 PM. After 10 minutes, the arrival rate declines to 60 persons per hour and continues at that level for 20 minutes. If the service rate is 2.5 persons/minute. (3)a.Describe the performance of the system, assuming that all the factors remain the same. (Longest queue, longest delay, total delay, average delay/person, etc.)b.Draw a neat sketch of the system. (Apply the D/D/1 model)arrow_forwardRefer to picture, all streets are one way numbers show how many cars enter or leave the city via this section of streets in a one hour period. The variables x,y,z,w represent the cars that travel along the portion of 1st, 2nd, avocado aircraft streets during this period. Assume no cars stop or park. Set up appropriate system of linear equations needed to find x,y,z,w. DONT SOLVE, JUST SET UP. Hint, the total # of cars going in an intersection must equal the total # of cars coming out of that intersection)arrow_forwardPlz solve it within 30-40 mins I'll give you multiple upvotearrow_forward
