Suppose that an airplane is asked to stay in a holding pattern near an airport. the distance of the plane to the airport is described by the following. =dt+14978sinπ6t in this equation, dt is the distance of the plane to the airport (in miles), and t is the time (in minutes) after the plane enters the holding pattern. during the first 12 minutes after the plane enters the holding pattern, when will the plane be 190 miles from the airport? do not round any intermediate computations, and round your answer(s) to the nearest hundredth of a minute. (if there is more than one answer, enter additional answers with the "or" button.)

(01.03 mc) which of the following is a step in simplifying the expression x multiplied by y to the power of 2 over x to the power of negative 3 multiplied by y to the power of 3, the whole to the power of negative 4. select one: a. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 7 multiplied by y to the power of negative 1. b. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of 12 multiplied by y to the power of negative 12. c. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of negative 3 multiplied by y to the power of 3. d. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 3 multiplied by y to the power of 3.
