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

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

so, converting firstly the mixed fractions to improper fractions and then "adding".

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
