Does the formula V = 4/3 pi r^3 represent a linear or nonlinear function? Explain.
Levart [38]
This is the volume of the sphere & is not at all a linear function.

A linear function of the form of y=kx (k is a given number/coefficient) where

y & x grow at the same rate. Then whatever the input (x) it will generate an output (y) always in the ration y/x, whereas v=4/3 πr³ (coefficient =k =4/3(π), if r increase by 2 units v will increase by 2³ =8 & for r = 3, v increase by 3³ =27.

In short v increases quicker than r. No it's not a linear function

A+b+c+d=770<br> a+b=c+d <br> a-b=49<br> c-d=211<br> Find numbers.
allochka39001 [22]
A+b = c+d
a+b = 770/2    ( a+b+c+d = 770)
a+b = 385
c+d = 385

a+b+a-b = 385+49
         2a  = 434
           a  = 434/2
           a  = 217
 a-b=49
217-49= b
b         = 168

c+d+c-d = 385+211
         2c = 596
           c = 596/2
           c = 298

c-d = 211
c-211= d
298-211 = d
           d  = 87

Therefore, a=217, b=168, c=298, d=87
