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. ∬D1x2+y2dA, where x2+y2≤4
∫0∫01x, dx dy
∬Zz2 dV, where E is:1≤x≤2,3≤y≤4,5≤z≤6
∬EdV, where E is:x2+y2+z2≤4,x≥0,y≥0,z≥0
a. polar coordinates
b. cartesian coordinates
c. cylindrical coordinates
d. spherical coordinates

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
