3) Consider a Cylinder with the x-axis as the axis of symmetry and a radius of base equal to 3. a) Find a parametric representation of the portion of the cylinder which is in the octant x >= 0,y >= 0,2 >= 0 and is
confined between the planes x = 1 and x = 4.
b) Using the parametric representation of part a) above, calculate the surface area of the portion of the cylinder. ​

Jenny invests $2,000 at an interest rate of 5%. the amount of money, me, in jenny's account after tyears can be represented using the equation ma-2000(1.05). if jenny would have invested the same amount of money at the same interest rate four years ago, the equation representing the amount of money mo. in her account would be represented using the equation! mg = 2000(105)*** which of the following is equivalent to mp? 2000(105) om- 1.05 2000(1.05) mo 1059 mp-2000(1.05) (105) mp - 2000(1.05) + (1.05)
