0 Show your work for any calculations needed or simplifications made! 0 Clearly show your work and the steps necessary to solve each problem, including sketching diagrams that represent each situation. 1. A perfect triangle is a triangle with two key characteristics: 1) all three side lengths are positive integers, and 2) the area of the triangle area is equal to its perimeter. Is a triangle with sides of length 8, 9, and 16 a perfect triangle? Set up expressions and show the work needed to solve in order to answer the question. 2. Forest fire tower Laurel is located 90 miles due west of forest fire tower Springs. A forest fire is located on a bearing of N 440 E from tower Laurel and a bearing of N 16'J E from tower Springs (the eastern station). There is a fire-lighting crew located 38 miles from station Springs on a bearing of N 61 E (from station Springs). a. Draw a diagram and label it with the given information to represent this situation. b. Determine the distance of the fire from both fire stations. 0. How far is the fire-fighting crew from the tire? 3. Bob has 8 pieces of square index cards that each measures 8 inches per side. Using a pair of scissors, he cuts each piece in half (so the resulting size is 8" x 4") and then places all the resulting card pieces in a new stack. If he repeats this procedure 4 more times, how many pieces of card stock will he have and what will be the measure of each piece? (Note: All cuts will be made along the longer edge of the piece if the piece of index card is not square.) Determine the conic section given by each of the following equations. Be sure to show all work to nd the standard form of the equation of each conic section. 10 points each. Correct conic section {2 points} All work shown {8 points) 1. 3x2+ 5y2- 12x + 30y = 42 2. x2+3y2+4x=5 3. x2+2x+4y=7 \f0 Show all steps taken and work needed to determine the needed equation and to answer each question. For those that require a sketch of the graph, be sure to label the x and y axes with appropriate increments, and label points on the graph. 1. The equation 3!2 4y 4x2 + 13 = 0 will produce a hyperbola. How can we tell by simply observing the equation? In what directions do the branches of this hyperbola open? How do you know? Explain. Sketch a graph of this hyperbola, clearly indicating how you have determined the key characteristics (center, vertices, eccentricity, foci}. Give the domain and range of this hyperbola. 2. Find the standard form of the equation of the ellipse satisfying the following conditions: endpoints of major axis (5, 4) and (3, 4); endpoints of minor axis (1, 1) and (1, 7). Graph this conic, marking the center and yertices. 3. An Olympic-distance triathlon includes a 1.5 km swim. To determine the swim course of an Olympic-distance triathlon in Shoe Lake, the planners need to first find the distance between points A and B on opposite sides of a lake in order to determine where to place the buoys that will mark the swim course. You have been called in to help with determining the distances. From a point C on the shore, you find that CA = 259 m, CB: 423 m, and angle ACB measures 132\". T a. Determine the distance across the lake. b. Is the lake long enough to simply have an \"out-and-back" swim course for this triathlon (that is: swimming from point A to point B and then back to point A)? If not, what additional distance will need to be set off of the straight-line distance between A and Bin order to meet the distance requirements for this triathlon
