Math 121 Trigonometry Banta F16 Test Final Ma This Question: 1 pt 21 of 30 (27 complete) v plot the point, given its polar coordinates. Give at least two other pairs of polar oA coordinates for the point. (2.225\") choose the graph of the ordered pair (2.225°). u Which of the following is not equivalent to (2.225 o A. (-2,406 O B. (2,405) O c. (2.585\") o D. (-2,45 Click to select your answer Time Remaining: 00:32:39 Sub This Test: 30 pts

Solution

To find the equivalent polar coordinates we have to use the following formula

(r, theta+-360) , (-r,thet+-180)

(2,225+-360) , (-2,225+-180)

(2,585),(2,-135)    (-2,45),(-2,405)

Therefore (2,405) is not an equivalent coordinate

Hence the correct option is B
