D. [10 pts] The vector-valued function r (t) = (to - 4t, 1 -2t2) traces out the curve below. As seen in the image, the curve self intersects at (0, -7). ( x , y ) = (0-7) Set up and integral that represents the length of the loop of the curve above (0, -7). Then, evaluate the integral to find the length. Report your answer to 3 decimal places. A) 21.725 + .002 (B 340.081 + .002 C 13.153 +.002 (D 0.000 + .002 E None of these Note that the 1.002 indicates that you should allow for a discrepancy of .002 with the answer listed. For instance, if you find the the answer to be 21.726, you should select Choice A. Explanation
