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

a. spherical coordinates

b. cylindrical coordinates

c. polar coordinates

d. cartesian coordinates

i cant see the graph

step-by-step explanation:

y=sec x is the correct answer

~batmans wife dun dun

d. you cannot tell because there are no values shown.

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
