A(correct)Correct Answers:A3.(1 point) To find the length of the curve defined byy=2x6+15xfrom the point (0,0) to the point (3,1503), you’d have to computeZbaf(x)dxwherea=,b=, andf(x) =.Solution:Solution:Since we are integrating with respect tox, we have to integratep1+(y0(x))2from 0 to 3.Soa=0,b=3, andf(x) =p1+((2x6+15x)0)2=p1+(12x5+15)2.Answer(s) submitted:03sqrt(1+(12xˆ5+15)ˆ2)(correct)Correct Answers:03sqrt(1 + (12*(x**(5)) + 15)**2)
4.(1 point)Given the equation:xy=21, set up an integral to find thelength of path fromx=atox=band enter the integrand be-low. (i.e. if your integral isL=Rbac2x2
5.(1 point) Find the length of the arc formed byy=18(-0.5x2+16ln(x))fromx=3 tox=8
