- Storage A cylindrical oil tank has a radius of 36 inches. A circular hole with radius 4 inches has been drilled 15 inches below the center of one base of the tank. Find an equation of the circular hole, using the center of the base of the tank as the origin and the axes.arrow_forwardFind an equation of the planearrow_forwardWhat are the coordinates?arrow_forward
- A child is walking to school in winter. The sidewalk is S = 300 feet long and then turns at a right angle and goes anotherl = 40 feet before reaching the door of the school. The child, however, cuts through the snow x feet before the corner, and travels through the snow on BC. If the speed of the child through the snow is of the speed of the child on the sidewalk, then where should the child leave the sidewalk in order to get to school most quickly?arrow_forwardConvert r= 3sec e to its equivalent Cartesian equation.arrow_forwardA chicken coop has been built 30 yards south of a farmhouse and is enclosed by a circular fence. Following a linear path that joins the farmhouse to the chicken coop, you must travel 24 yards before arriving at the fence. With the farmhouse as the origin and the positive x- and y-axes oriented east and north, respectively, what is the equation of the circular fence?arrow_forward
- Solve (-1+i)6 using De Moivre’s Theorem. Express final answer as rectangular form.arrow_forwardThe human cannonball In the 1940s, the human cannonball stunt was performed regularly by Emmanuel Zacchini for The Ringling Brothers and Barnum & Bailey Circus. The tip of the cannon rose 15 feet off the ground, and the total horizontal distance traveled was 175 feet. When the cannon is aimed at an angle of 45°, an equation of the parabolic flight (see the figure) has the form y = ax? + x + c. (a) Use the given information to find an equation of the flight. (b) Find the maximum height attained by the human cannonball. Exercise 48 175'arrow_forwardUsing the Position Equation In Exercises 111-114, use the position equation given in Example 8 as the model for the problem. You drop a coin from the top of the Eiffel Tower in Paris. The building has a height of 984 feet. (a) Use the position equation to write a mathematical model for the height of the coin. (b) Find the height of the coin after 4 seconds. (c) How long does it take the coin to strike the ground?arrow_forward
