The constant of proportionality is k > 0, v is the volume, s is the surface area. remember that you must use the prime notation for derivatives, not the leibniz notation, in all of your answers. a raindrop evaporates at a rate that is proportional to the surface area, write this as a differential equation: equation editorequation editor=0.since v=43πr3 we have by the chain rule that dvdt=v′=equation editorequation editor. substituting this into the original differential equation, along with the equation s=4πr2, and solving for r′ we find that

a negative exponent is translated as follows:

so, we have

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
