Suppose r(t) = cos t i + sin t j + 3tk represents the position of a particle on a helix, where z is the height of the particle above the ground. (a) is the particle ever moving downward? when? (if the particle is never moving downward, enter dne.) t = (b) when does the particle reach a point 15 units above the ground? t = (c) what is the velocity of the particle when it is 15 units above the ground? (round each component to three decimal places.) v = (d) when it is 15 units above the ground, the particle leaves the helix and moves along the tangent line. find parametric equations for this tangent line. (round each component to three decimal places.)

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
