(a) What is t when the particle has height 6? t = 2 (b) What is the velocity of the particle when its height is 6? v = <0, pi, 3> (c) When the particle has height 6, it leaves the helix and moves along the tangent line at the constant velocity found in part (b). Find a vector parametric equation for the position of the particle (in terms of the original parameter t) as it moves along this tangent line. L(t) = i +(pit)j + (6 + 3t) k

The equation x³ - 1.2x? - 8.19x + 13.23 = 0 has a double root close to x = 2. Determine this root with the Newton-Raphson method within four decimal.

hi! I am working on thismath problem but I am quite confused about how to solve it.

11. Solve for x (give the exact answer), 3ln x + 8 = 17
