The region bounded by y=x2 and y=sin(πx/2) is rotated about the line x=−1. Using cylindrical shells, set up an integral for the volume of the resulting solid.
The limits of integration are:
a=

b=

and the function to be integrated is:

20 only answer if 100% sure most high school-aged teens are very active. a. true b. false

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
