Diego's age dis 5 more than 2 times his sister's age s. This situation is represented by the equation d=2s +5. Which equation is equivalent to the equation d=2s +5?
d = 2(5+5)
d-5-2s
d -2 = 5 + 5
d 2 = 5 + 5

Consider the integral: 4 0 16 − y2 − 16 − y2 4 1 x2 + y2 dz dx dy . (a) describe w. use the standard view of the x, y, and z axes. front half of a cone with a rounded top. full cone with a flat top. right half of a cone with a flat top. front half of a cone with a flat top. right half of a cone with a rounded top.

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
