The number of items is modeled by h(x) = 0.42x2 + 0.3x + 4, and the cost per item is modeled by r(x) = 0.005x2 0.2x + 7. The total cost is the product of the number of items and the cost per item. Identify a polynomial q(x) that can be used to model the total cost. q(x) = 0.005x2 0.2x + 7 q(x) = 0.0021x4 0.069x3 + 3.02x2 + 2.9x + 28 q(x) = 0.42x2 + 0.3x + 4 q(x) = 0.0021x4 0.0855x3 + 2.86x2 + 1.3x + 28 Question 4 of 25Identify the matrix transformation of TUV, which has coordinates T(0, 1),U(1, 2), and V(2, 0), for 90 rotation, clockwise. Then identify the correct vertices of the image. Identify the matrix transformation of TUV, which has coordinates T(0, 1),U(1, 2), and V(2, 0), for 90 rotation, clockwise. Then identify the correct vertices of the image. Question 5 of 25Skip to question text. A toy rocket is launched from a platform 39 feet above the ground at a speed of 83 feet per second. The height of the rocket in feet is given by the polynomial 16t2 + 83t + 39, where t is the time in seconds. How high will the rocket be after 3 seconds? 105 feet 144 feet 240 feet 2592 feet Question 6 of 25Skip to question text. E is the encoding matrix. Use E to decode the coded message matrix.
