Answer:

$ 12.09

Step-by-step explanation:

formula Y = KX

Where; y = $ 24.18

x = 2 books

k = constant of proportionality

Step 1. Do the equation based on the formula

Y = kx

$24.18 = k2

Step 2. Divide by 2

$24.18/2 = k2/2

k = $12.09 (answer)

Given:

The set of pair and graphs.

To find:

The domain and range.

Solution:

We know that,

Domain is the set of x-values or input values.

Range is the set of y-values or output values.

(a)

The given set of ordered pairs is

{(-3,3),(5,5),(-3,2),(5,3)}

Here, the x-coordinates are -3, 5, -3, 5.

A set contains distinct values.

Therefore, the domain is {-3,5}.

(b)

The graph is given.

From the given graph the set of ordered pairs is

{(-2,1),(-1,0.5),(-1,3),(0,0),(0,2),(1,0.5),(1,3)(2,1)}

Here, the y-values are 1, 0.5, 3, 0, 2, 0.5, 3, 1.

Therefore, the range is {0, 0.5, 1, 2, 3}.

(c)

The graph is given.

From the given graph the set of ordered pairs is

{(-2,3),(-1,3),(0,1),(2,4)}

Here, the x-values are -2, -1,0, 2.

Therefore, the domain is {-2,-1,0,2}.

Question is in picture need help asap

Andrej [43]

The given expression is:

$\sqrt[4]{ 9^{ \frac{1}{2}x } }$

4th root is equivalent to raising the expression to power $\frac{1}{4}$ . So, re-writing the expression by converting radical to exponent:

$( 9^{ \frac{1}{2}x } )^{ \frac{1}{4} } \\ \\ 
= 9^{ \frac{1}{8}x }$

Therefore, the given expression simplifies to $9^{ \frac{1}{8}x }$
