Find T(t), N(t), aT, and aN at the given time t for the space curve r(t). [Hint: Find a(t), T(t), aT, and aN. Solve for N in the equation a(t) = aTT + aNN.]. r(t) = e^t sin ti + e^t cos tj + e^tk
t = 0

Factor the trinomial below. 12x^2 - 32x - 12 a. 4(3x+3)(x-1) b. 4(3x+1)(x-3) c. 4(3x+6)(x-2) d. 4(3x+2)(x-6)

Complete the conditional statement. if a + 2 < b + 3, then a < b b < a a – b < 1 a < b + 1
