Consider the multivariable function f\left(x, y,z\right)=\frac{x^3-2.5y^2+\frac{z }{2}}{z\left(x-y\right)}f ( x , y , z ) = x 3 − 2.5 y 2 + z 2 z ( x − y ). Evaluate f\left(2,3,1\right)f ( 2 , 3 , 1 ). Round your answer to two decimal places.

Step-by-step explanation:

Given the function:

To find:

The value of = ?

Solution:

means the values of as:

Let us put the given values in the given function and let us solve for it:

Therefore, the answer is:

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
