An agricultural sprinkler distributes water in a circular pattern of radius 110 ft. It supplies water to a depth of e−r feet per

ludmilkaskok [199]

Answer:

the total amount of water supplier per hour to the region within a circle of radius R=110 ( that is from distance r, 0<r<110)

$W(R) = 2\pi [1-(R+1)e^{-R}]$

Step-by-step explanation:

if f(r) describes the water supplied at a distance r , the total amount supplied inside a region that goes from 0 until the circle of radius R, is the sum of all f(r) values from 0 until R, that is the integral value over these limits.

The formula deduction can be found in the attached picture

There is an "r" that multiplies e^-r as result of changing from rectangular coordinates to polar ones.(dx*dy --> r*dr*da)

Whats the solution

Sergio039 [100]

Answer:

Step-by-step explanation:

To find the center and the radius, we need to put the equation in the (x-a)^2+(y-b)^2=r^2 [a is the x-coordinate, b is the y-coordinate, and r is the radius].

(x+6)^2+(y+7)^2 - 36 - 49 + 69 = 0

(x+6)^2+(y+7)^2 - 16 = 0

(x+6)^2+(y+7)^2 = 16

(x+6)^2+(y+7)^2 = 4^2

The center is (-6,-7) and the radius is 4.

Hope this helps!
