Please help me with this. Thanks.

Activity 1 can no Duncan Complete your PRECAL boxes showing all necessary steps. This will serve as rubrics, 1 point for every correct answer in each box. The last column is done for you. The more logical and systematic, the better. 1 . A faster way of traveling by land from Bataan all the way to Cavite could be possible in the future under Bataan-Cavite Interlink Bridge (BCIB) Project, a 32.15-kilometer ocean view mega bridge highway. Jonas is interested about the cable suspension between two towers that can be hung in the shape of parabola. The towers supporting the cables could be 1000 meters apart and are 160 meters high and which is at its lowest, is 40 meters above the road. Can you make a design of this project that represents a parabola and try to nd the equation of this parabola, if we put a coordinate system so that the axis of the parabola is the y-axis, and the road is on the x-axis? How high is the cable 300 meters from a tower? Use the PRECAL method in doing so. 11 2. A single-lane street 10 ft wide goes through a semicircular tunnel with radius 9 ft. How high is the tunnel at the edge of each lane? Round off to 2 decimal places. 3. The towers supporting the cable of a suspension bridge are 1200 m apart and 170 m above the bridge it supports. Suppose the cable hangs, following the shape of a parabola, with its lowest point 20 m above the bridge. How high is the cable 120 In away from a tower? 4. A satellite dish in the shape of a paraboloid is 10 ft across, and 4 ft deep at its vertex. How far is the receiver from the vertex, if it is placed at the focus? Round off your answer to 2 decimal places. 5. A satellite dish shaped like a paraboloid has a diameter 2.4 ft and depth 0.9 it. If the receiver is placed at the focus, how far should the receiver be from the vertex? STEPS P R E C A L 1. 2. 3. 4. 0.4 ft 5. 1.6ft
