Please list all the steps that lead to the answer. Thank you. Question 9 and 10

6. Find the arc length for #5 7. Given parametric equations x =3? + 1 . y=t3 _ 1. nd the equation of the tangent line going through { 4, O} 8. Given polar equation r = 2 + 2 sing , nd the points where tangent line is horizontal. 9. Find the area for r = 35in{23} (one paddle only) Be sure to draw the picture. It will help you to see the limits. 10. Find the area inside r = 1+cosa and out side r = '1. Be sure to graph and shade the area you are looking for. Extra credit: For what twill the graph of the parametric equations concave down '3 (10 points) Xit) = 2e' + 3, y = 61:3
