Answer:

Below.

Step-by-step explanation:

35% as a decimal can be written as 0.35. Because it is 0.35 out of 1.00 or 0.35%.

As a fraction, you could write it as 35/100 because its 0.35 or 35/100

Answer:

decimal =0.35 and fraction= 7/20

Step-by-step explanation:

For removing percentage sign , divide by 100 so 35% becomes 35/100 and for converting it into decimal just add a decimal point before 35 since there is 100 in the denominator so it becomes 0.35 .

For converting 35% into fraction just remove the percentage first by dividing by 100 so it becomes 35/100 and take out a factor of 5 common from both numerator and denominator so 35/100 becomes 7/20 .

Answer:

the range is {7,5,1}

Step-by-step explanation:

To find the range, just plug in the domain into the function.

f(-1) = -2(-1) + 5 = 7

f (0) = -2(0) + 5 = 5

f(2) = -2(2) + 5 = 1

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)
