Here is the detailed solution to your questions: Item 2 a) Determine whether the meeting will start by 2:00 PM. Step 1: Identify the pattern of member arrivals. Let t be the number of hours past 7:00 AM. • At 7:00 AM (t=0): 0 members • At 8:00 AM (t=1): 1 member (1^2) • At 9:00 AM (t=2): 4 members (2^2) • At 10:00 AM (t=3): 9 members (3^2) • At 11:00 AM (t=4): 16 members (4^2) The pattern for the number of members arrived is t^2. Step 2: Calculate the number of members who will have arrived by 2:00 PM. 2:00 PM is 7 hours after 7:00 AM (14:00 - 7:00 = 7 hours). So, t=7. Number of members = 7^2 = 49. Step 3: Compare with the meeting start condition. The meeting will start if at least 45 members have arrived. Since 49 members have arrived, and 49 45, the meeting will start. The meeting will start by 2:00 PM. b) Help Matovu to determine: i) The constant transport costs. Step 1: Formulate two equations based on the given information. Let P be the unit price of one phone and T be the constant transport cost. For 5 phones: 5P + T = 618,000 (1) For 8 phones: 8P + T = 978,000 (2) Step 2: Solve the system of equations for P and T. Subtract equation (1) from equation (2): (8P + T) - (5P + T) = 978,000 - 618,000 3P = 360,000 P = (360,000)/(3) P = 120,000 Substitute the value of P into equation (1): 5(120,000) + T = 618,000 600,000 + T = 618,000 T = 618,000 - 600,000 T = 18,000 The constant transport costs are Shs. 18,000. ii) The amount to be charged for 12 phones. Step 1: Use the unit price (P) and transport cost (T) found previously. Unit price P = Shs. 120,000. Transport cost T = Shs. 18,000. Step 2: Calculate the total cost for 12 phones. Total cost = (Number of phones × Unit price) + Transport cost Total cost = 12P + T Total cost = 12(120,000) + 18,000 Total cost = 1,440,000 + 18,000 Total cost = 1,458,000 The amount to be charged for 12 phones is Shs. 1,458,000. c) Help the officials to: i) Draw the graph showing the number of trees that were cut during the selected number of days. Step 1: Calculate the number of trees cut for each day from Monday (x=1) to Saturday (x=6) using the function f(x) = -x^2 + 5x + 6. • Monday (x=1): f(1) = -(1)^2 + 5(1) + 6 = -1 + 5 + 6 = 10 • Tuesday (x=2): f(2) = -(2)^2 + 5(2) + 6 = -4 + 10 + 6 = 12 • Wednesday (x=3): f(3) = -(3)^2 + 5(3) + 6 = -9 + 15 + 6 = 12 • Thursday (x=4): f(4) = -(4)^2 + 5(4) + 6 = -16 + 20 + 6 = 10 • Friday (x=5): f(5) = -(5)^2 + 5(5) + 6 = -25 + 25 + 6 = 6 • Saturday (x=6): f(6) = -(6)^2 + 5(6) + 6 = -36 + 30 + 6 = 0 Step 2: List the points for plotting the graph. The points to plot are: • (Monday, 10) • (Tuesday, 12) • (Wednesday, 12) • (Thursday, 10) • (Friday, 6) • (Saturday, 0) The graph would be a downward-opening parabola passing through these points. ii) Obtain the day(s) on which many trees were cut. Step 1: Determine the maximum value of f(x). The function f(x) = -x^2 + 5x + 6 is a downward-opening parabola, so its maximum value occurs at its vertex. The x-coordinate of the vertex for a quadratic function ax^2 + bx + c is given by x = -(b)/(2a). Here, a=-1 and b=5. x = -(5)/(2(-1)) = (5)/(2) = 2.5 This means the maximum value occurs between day 2 (Tuesday) and day 3 (Wednesday). Step 2: Compare the number of trees cut on the days closest to the vertex. From the calculations above: • Tuesday (x=2): 12 trees were cut. • Wednesday (x=3): 12 trees were cut. The maximum number of trees were cut on Tuesday and Wednesday. 3 done, 2 left today. You're making progress.
