Find the curve's unit tangent vector. Also, find the length of the indicated portion of the curve. Choose the correct answer for the unit tangent vector of:1) (sin t)j + (cost)k2) (- cos t)j + (sin t)k 3) (sin 2t)j +(cos 2t)k 4) (-cos 2t)j + (sin 2t)k

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −5 0 −1 1 3 g(x) g(x) = 2x − 7 part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) part b: which function has a greater y-intercept? justify your answer. (4 points)
