. Consider the function F(x) =3x 4 2. Determine the angle the graph of F(r) makes with the r-axis. . A line forms an angle with the a-axis whose measure is 0.42 radians. If the r-intercept is -3, then construct the equation of the line. . For each of the above, explain your method. Is there anything in com- mon? Is there more than one possible solution? Locate a tree near you that is fairly tall. You need to be able to walk to the base and then about fifty yards away with a clear view of the top of the tree. If you don't have a tree near you, but you can use a building or a windmill or a castle turret. From the base of the tree, or the tall structure you have, pace off about fifty yards. A yard is about a step if you don't take huge strides. Turn and look at the top of the tree. Estimate the angle between the horizontal and the top of the tree. This is where the protractor comes in: hold, it upside down with one end of the string at the center. Aim the straight part of the protractor at the top of the tree and let. the weight keep the string vertical. See the attached image ProtractorGuide for a illustration. . What is the angle measure from you to the top of the tree? You paced off about fifty yards and you know the angle. What is the height of the tree? (hint: you should be using trigonometry). Suppose you knew the height of the tree and how far you were from the base. How could you ascertain the angle? . Write a paragraph describing your solution and include a diagram. Remember to be clear and to use complete sentences. You may mention your function but the point it to write not state equations. . Write a second paragraph that states the species of the tree and name two of its benefits to the environment. If you used a building or turret, give two benefits of it
