Calculus question

Use linear approximation, i.e. the tangent-line, to approximate v 49.1 as follows: Let f (a) = Vac. The equation of the tangent line in slope-intercept form to f(x) at x = 49 can be written in the form y = ma + b where: m b Using this, we find our approximation for v 49.1 is NOTE: For this last part, give your answer to at least 6 significant figures or use fractions to give the exact answer.
