(1 point) Consider the path r(t)=(14t,7t2,7lnt)r(t)=(14t,7t2,7l n⁡t) defined for t>0t>0. Find the length of the curve between the points (14,7,0)(14,7,0) and (42,63,7ln(3))(42,63,7ln⁡(3)).

If you have a set of parallel lines a and b cut by transversal x, if angle 1 = 167 degrees, what is angle 4 and why. also what is the measure of angle 5 and why? you need to use the names of the angle relationship and explain.
