Section 7.4: Problem 3 (1 point) To find the length of the curve defined by y = 6r* + 2r from the point (0,0) to the point (2,52), you'd have to compute - f(x)dr a where a b and f(I)Section 7.4: Problem 4 [1 point) Given the equation: my = 20, set up an integral to nd the length of path fmm z = a to z = b and enter the integrand below. [i.e_ if your integral is L = I: dz enter % as your answer.)
