find the arc length parameter along the given curve from the point where t0 by evaluating the integral s(t). then find the length of the indicated portion of the curve r(t) i jt k, where 0t .

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
