Answer:

(1/4)/(2/3) = 3/8

Step-by-step explanation:

(1/4)/(2/3) = 3/8

This can be confirmed by a couple of different methods of dividing fractions.

1) express using a common denominator and take the ratio of numerators.

(1/4)/(2/3) = (3/12)/(8/12) = 3/8

2) invert the denominator and multiply

(1/4)/(2/3) = (1/4)(3/2) = (1·3)/(4·2) = 3/8

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:

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

$\huge\text{Hey there!}$

$\mathsf{2(4 - 1)^2 - 3 + 2(5)}$

$\mathsf{4 - 1 = \bf 3}$

$\mathsf{= 2(3^2) - 3 + 2(5)}$

$\mathsf{3^2}\\\mathsf{= 3\times3}\\\mathsf{= \bf 9}$

$\mathsf{= 2(9) - 3 + 2(5)}$

$\mathsf{2(9)}\\\mathsf{= \bf 18}$

$\mathsf{= 18 - 3 + 2(5)}$

$\mathsf{18 - 3}\\\mathsf{= \bf 15}$

$\mathsf{= 15 + 2(5)}$

$\mathsf{2(5)}\\\mathsf{= \bf 10}$

$\mathsf{= 15 + 10}\\\mathsf{= \bf 25}$

How do you eliminate the parameter theta to find a Cartesian equation of the curve: x=sin(1/2 theta), y=cos(1/2 theta), 0 is les

kiruha [24]

The answer to the problem is as follows:

x = sin(t/2)
y = cos(t/2) 

Square both equations and add to eliminate the parameter t: 

x^2 + y^2 = sin^2(t/2) + cos^2(t/2) = 1 

The final step is translating the original parameter limits into limits on x and y. Over the -Pi to +Pi range of t, x varies from -1 to +1, whereas y varies from 0 to 1. Thus we have the semicircle in quadrants I and II: y >= 0.
