Convert the polar equation to rectangular coordinates. r + cos0 = 4. Ox +y + x =16x2 + yz Ox2 + y2 + x = 16x2 + yz Ox2 + y2 + y = 4x2 + 2 x2 + y2 + x = 4x2+ y2Use the information given about the angle 9, 0 s B 5 211, to find the exact value of the indicated trigonometric function. , tan ii -::: 0 Find aimlti]. Refer to the figure, where the two smaller triangles en top are right triangles. Find the numerical 1value of sin(2 y]. A\" 7 Let a and B be angles in the first quadrant such that seca = 3 / 2 and cscB = 3. Find cosa - B.\fA pilot sets out from an airport and heads in the direction N30W, flying at a constant speed of 305 mi/h. Forty-five minutes later the pilot makes a course and speed correction and now heads in the direction N50W and reduces her speed to 175 mi/h. Half an hour later, engine trouble forces her to make an emergency landing. Find the distance between the airport and the final landing point. 480 mi 312.41 mi 314.26 316.25 mi\fConvert the following in rectangular coordinates to polar coordinates with r > 0 and 0
