Rooter Plus charges a $25 service fee plus $40 per hour of work done. Is this a proportional or non-proportional relationship?

Dominik [7]

Answer:

Non-proportional; the rate of change is $40/hour

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u>and the line passes through the origin</u>

Let

x -----> the number of hours

y ----> The total charge in dollars

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=40\ \$/h\\b=\$25$

substitute

$y=40x+25$

This relationship is not proportional, because the line not passes through the origin

therefore

Non-proportional; the rate of change is $40/hour

Find the simplified product 2 square root 5x^3(-3 square root 10x^2

Ivanshal [37]

The simplified product of $2\sqrt{5x^{3} }$ and -3 $\sqrt{10x^{2} }$ is -30 $x^{5/2} \sqrt{2}$ .

Given Two expressions: -3 $\sqrt{10x^{2} }$ and 2 $\sqrt{5x^{3} }$ .

We have to multiply both the expressions and it can be done as under:

-3 $\sqrt{10x^{2} }$ *2 $\sqrt{5x^{3} }$

Firstly we have to multiply -3 with 2 to get

=-6 $\sqrt{10x^{2} }\sqrt{5x^{3} }$

Then we have to find square root of x cube and x square which is x to the power 3/2 and x to the power 1.

= $-6x^{3/2} x\sqrt{10}\sqrt{5}$

Now we have to multiply both the numbers in the root to get the answer;

=-6 $x^{5/2} \sqrt{50}$

Square root of 50 is 5 root 2.

=-6*5 $\sqrt{2}$ $x^{5/2}$

=-30 $\sqrt{2}$ $x^{5/2}$

Hence the simplified product is -30 $\sqrt{2}$ $x^{5/2}$ .
