Determine whether the following curve uses arc length as a parameter. If not, find a description that uses arc length as a parameter. r(t) = (41²,6t² √69+²), for 1 sts4 ... Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. O A. r(t) does not use arc length as a parameter. A description of the curve that uses arc length as a parameter is r(s) = () for SSS (Type exact answers, using radicals as needed. Use 0 for the lower bound of s.) OB. r(t) uses arc length as a parameter.
