1. (8 points) J dx 2. (8 points) J (- 18z + 36)( - 2z - 4) dz 3. (8 points) An equation of line tangent to a curve at the point (1,3) is y = 2 + x. If at any point (x, y) on the curve, d,z = 6x, find an equation of the curve that satisfies the given conditions.4. (8 points) Two stones are thrown vertically upward at the same time, one with an initial velocity of 32 ft/s from a height of 128 ft, the other with an initial velocity of 64 ft/s from a height of 80 ft. If the stones travel along parallel paths, when will the second stone overtake the first
