Find a vector-parametric equation r 1(t)=⟨x(t),y(t),z(t)⟩r→1(t)=⟨x(t),y (t),z(t)⟩ for the shadow of the circular cylinder x2+z2=9x2+z2=9 in the xzxz-plane.

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form

The answer should be 58 cm3.
