Devorah is filling a pool with a hose. the volume, , in liters, of water coming out of the hose in minutes is given by the function . however, it is a sunny day, and water is also evaporating from the pool. therefore, the volume, , in liters, of water in the pool minutes after devorah started filling it is given by .

let be the volume of water, in liters, that has evaporated from the pool minutes after devorah started filling it.

write a formula for in terms of and .

write a formula for in terms of .

Formula for in terms of is:

Formula for in terms of is:

Step-by-step explanation:

Given:

The expression for volume of water in a pool when there is no evaporation is:

Where, is the minutes passed.

The expression for volume of water in a pool on a sunny day when there is evaporation of water is:

Now, the change in the volume of the water in the pool is nothing but the volume of water that has been evaporated.

So, volume of water that has been evaporated is given as:

But as per question, evaporated volume of water is given by . Therefore,

Now, plug in the values of

Hence, formula for in terms of is:

Formula for in terms of is:

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
