Sara made enough raspberry jam to fill 3 1/8 jars of equal size. Then she made strawberry jam. If the amount of the strawberry jam she made was 1/5 the amount of raspberry jam she made, how many jars could she fill with strawberry jam?

2x minus y equals 6, x plus y equals negative 3

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.

Use stokes' theorem to evaluate c f · dr where c is oriented counterclockwise as viewed from above. f(x, y, z) = xyi + 5zj + 7yk, c is the curve of intersection of the plane x + z = 8 and the cylinder x2 + y2 = 81.
