Answer:
i think it might be 17%
Step-by-step explanation:
if you divide 100 by 10 u get 10 then divide 10 by 6 to get 1.6666666667 round that to one decimal place to get 1.7 then times it by 10 to get 17
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}]](https://tex.z-dn.net/?f=W%28R%29%20%3D%202%5Cpi%20%5B1-%28R%2B1%29e%5E%7B-R%7D%5D)
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)
M is the mid-point : (0,1)
c is one end : (-3, -1)
n is the other end : (x, y)
The formula for the midpoint of a line segment is : (

,

)
Mid-point m : (

)
(0, 1) : (

)
Thus,

--- x = 3

y -1 = 2
--- y = 3
The co-ordinate of n is (3,3)
Answer:
10t - 25
Step-by-step explanation:
multiply each term in the parenthesis by the 5 outside
= (5 × 2t) + (5 × - 5) = 10t + (- 25) = 10t - 25
