Solve the problem.Ken is 6 feet tall and is walking away from a streetlight. The streetlight has its light bulb 14 feet above the ground, and Ken is walking at the rate of 1.3 feet per second. Find a function, d(t), which gives the distance Ken is from the streetlight in terms of time. Find a function, 
, which gives the length of Ken's shadow in terms of d. Then find 
.
A. (S ? d)(t) = 0.72t B. (S ? d)(t) = 2.2t C. (S ? d)(t) = 1.24t D. (S ? d)(t) = 0.98t
Find T, N, and B for the given space curve.r(t) = (6t sin t + 6cos t)i + (6t cos t - 6 sin t)j - 2k
A. T = (-cos t)i - (sin t)j; N = (sin t)i - (cos t)j; B = -2k B. T = (cos t)i + (sin t)j; N = (-sin t)i + (cos t)j; B = k C. T = (cos t)i - (sin t)j; N = (-sin t)i - (cos t)j; B = -k D. T = (-cos t)i - (sin t)j; N = (sin t)i - (cos t)j; B = -k
