Match the integrals with the type of coordinates which make them the easiest to do. put the letter of the coordinate system to the left of the number of the integral.

1. z2 dv where e is: ? 2? z? 2, 1? x2+y2? 2
2. ? ? d 1x2+y2 da where d is: x2+y2? 4
3. dv where e is: x2+y2+z2? 4, x? 0, y? 0, z? 0
4. z dv where e is: 1? x? 2, 3? y? 4, 5? z? 6
5. ? 10? y20 1x dx dy

How do i do this using elimination 2x+3y=12 x-y=6

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98

Given abcd ac=38 and ae=3x+4 find the value of x
