The variable y varies directly as x and inversely as z. When x = 4 and z= 14, y=2.

Fudgin [204]

Given:

The variable y varies directly as x and inversely as z. When x = 4 and z= 14, y=2.

To find:

The combined variation equation and find y when x = 6 and z= 3.

Solution:

The variable y varies directly as x and inversely as z.

$y\propto \dfrac{x}{z}$

$y=k\dfrac{x}{z}$ ...(i)

Where, k is the constant of proportionality.

Putting x=4, y=2 and z=14, we get

$2=k\dfrac{4}{14}$

$2=k\dfrac{2}{7}$

$2\times \dfrac{7}{2}=k\dfrac{2}{7}\times \dfrac{7}{2}$

$7=k$

Putting k=7 in (i), we get

$y=7\dfrac{x}{z}$

Putting x=6 and z=3, we get

$y=7\times \dfrac{6}{3}$

$y=7\times 2$

$y=14$

Therefore, the required equation is $y=7\dfrac{x}{z}$ and the value of y is 14 when x = 6 and z= 3.

Find the range of the function r(x) for the given domain. <br> r(x) = 2(2*)+3<br> D = {-1,0,1,3}

e-lub [12.9K]

Answer: R = {4, 5, 7, 19}

<u>Step-by-step explanation:</u>

Domain represents the x-values.

Range represents the y-values.

Insert the values of the domain into the given equation.

$\begin {array}{c|l|c}\underline{\ x\ }&\underline{\ 2(2^x)+3 =\ }&\underline{\ r(x)\ }\\ -1&2(2^{-1})+3=&4\\0&2(2^0)+3=&5\\1&2(2^1)+3=&7\\3&2(2^3)+3=&19\\\end{array}$
