Entered Answer Preview Result sqrt(145)*cos(6*pi*x+atan(8/9)) 145 cos 672 + tan1 * (0)) correct incorrect incorrect incorrect At least one of the answers above is NOT correct. 3 of the questions remain unanswered. (1 point) Reduce the equation to a single cosine function with positive amplitude: 9 cos(673) - 8 sin(67x) = sqrt(145)cos((6pix)+arctan(8/9)] -9 cos(672) - 8 sin(672) = 8 sin(672) - 9 cos(672) = 9 cos(672) + 8 sin(672) = Be sure to use at least five decimal places for your answers.
