Use linear approximation, i.e. the tangent line, to approximate v 25.2 as follows: Let f(ac) = Vac. The equation of the tangent line in slope-intercept form to f(x) at x - 25 can be written in the form y = mx + b where: m = 6 Using this, we find our approximation for v 25.2 is 5.019960 NOTE: For this last part, give your answer to at least 6 significant figures or use fractions to give the exact answer.
