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 −

Lelu [443]

Answer:

$f\left(2,3,1\right)=\bold{14}$

Step-by-step explanation:

Given the function:

$f\left(x,y,z\right)=\frac{x^3-2.5y^2+\frac{z}{2}}{z\left(x-y\right)}$

To find:

The value of $f(2, 3, 1)$ = ?

Solution:

$f(2, 3, 1)$ means the values of $x, y\ and\ z$ as:

$x=2\\y=3\\z=1$

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

$\Rightarrow f\left(2,3,1\right)=\dfrac{2^3-2.5\times 3^2+\frac{1}{2}}{1\left(2-3\right)}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{8-2.5\times 9+0.5}{1\left(-1\right)}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{8-22.5+0.5}{-1}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{-14}{-1}\\\\\Rightarrow f\left(2,3,1\right)=\bold{14}$

Therefore, the answer is:

$f\left(2,3,1\right)=\bold{14}$

Find the value of x in the diagram shown below.

Serggg [28]

Answer:

Step-by-step explanation:

According the property of inscribed angles and arcs, the angle is half of the arc length.

Solving :

∠CFB = 1/2 x ∡CB
∠CFB = 1/2 x 164°
∠CFB = 82°
∠CFB = ∠DFA (Vertically Opposite Angles)
<u>∠DFA = 82°</u>

What is the complete factorization of the polynomial below

DerKrebs [107]

Answer:

$a. \ (x-2)(x+i)(x-i)$

Step-by-step explanation:

First of all let's notice that $(x-i)(x-i)=(x-i)^2 = x^2+2xi-1 \in \mathbb{C}$ while our original polynomial is real. So we can rule out the even options B and D. At this point, if the polynomial has a factor of $(x-\alpha)$ it means tha $\alpha$ is a zero of the polynomial. Let's check both 2 (for option a) and -2 (for option c)
