Graph r = 3 - 2sin(θ) by constructing a table of values.

Graph the equation for values of x between 0° and 360° in multiples of 15°. y = cos(2x) The x y-coordinate plane is given. The curve begins at the point (0°, 1), goes down and right, crosses the x-axis at x = 90°, changes direction at the point (180°, −1), goes up and right, crosses the x-axis at x = 270°, and ends at the point (360°, 1).   The x y-coordinate plane is given. The curve begins at the point (0°, 2), goes down and right, crosses the x-axis at x = 90°, changes direction at the point (180°, −2), goes up and right, crosses the x-axis at x = 270°, and ends at the point (360°, 2).   The x y-coordinate plane is given. The curve begins at the origin, goes down and right, changes direction at the point (90°, −1), goes up and right, crosses the x-axis at x = 180°, changes direction at the point (270°, 1), goes down and right, and ends at the point (360°, 0).   The x y-coordinate plane is given. The curve begins at the point (0°, 1), goes down and right, crosses the…

In a certain piston engine, the distance x (in centimeters) from the center of the drive shaft to head of piston is given by the function (Function is in the image provided) Where (theta) is an angle in degrees between the crank and the path of the piston head. Find x when (theta) = 30(degrees) and when (theta) = 45(degrees) round answer to the nearest thousandth centimeter.

A table fan has a mark on the tip of one blade. The equation = = 23 cos (4x) + 38 represents the height of the mark, y centimetres, above the table x seconds after the fan is turned on. What is the height, in cm, of the mark above the table when it is closest to the table? Record your answer in the space provided below (digits only, no spaces).
