Suppose that y varies jointly with w and x and inversely with z and y = 320 when w = 6, x = 20, and z = 3.
makvit [3.9K]
I suppose we are to determine the proportionality constant of the variation. The equation for this proportionality is,
                          y = kwx / z
Substituting the known values,
                            320 = k(6)(20)/3
The value of k from the equation is 8.

Which of the following statements are true about the given rational equation? check all of the boxes that apply. 4 x 6 1 x2 = x
Agata [3.3K]

We can actually see that the statements that are true are:

A. x = 1 is a solution.

C. x = –1 is a solution.

<h3>What is rational equation?</h3>

Rational equation is actually known as an equation that contains at least one fraction. The denominator and numerator are known to be polynomials.

We can see then that:

\frac{4}{x + 6}  +  \frac{1}{ {x}^{2} }  =  \frac{x + 10}{ {x}^{3} + 6 {x}^{2}  }

It's clear that: x ≠ 0 and x ≠ -6.

Looking for the LCM of the left hand side, we will have:

\frac{4}{x + 6}  +  \frac{1}{ {x}^{2} }  =  \frac{4 {x}^{2 }  + (x + 6)}{(x + 6) {x}^{2} }

So, we will see that left hand side and right hand side are equal.

4 {x}^{2}  + x + 6 = x + 10

4 {x}^{2}  = 10 - 6

4 {x}^{2}  = 4

{x}^{2}  = 1

x = 1

or

x =  - 1

So, we can see that options A and C are correct.

Find the value of the expression below. Express your answer in scientific notation.
nirvana33 [79]

The value of the expression is 8.8 \times 10^{-2}.

Solution:

Given expression:

$\frac{\left(4.8 \times 10^{8}\right)}{\left(1.2 \times 10^{4}\right)} \times\left(2.2 \times 10^{-6}\right)

<u>To find the value of the given expression:</u>

Using exponent rule: a^m\times a^n=a^{m+n}

$\Rightarrow\frac{\left(4.8 \times 10^{8-6}\right)}{\left(1.2 \times 10^{4}\right)} \times\left(2.2 \right)

$\Rightarrow\frac{\left(4.8 \times 10^{2}\right)}{\left(1.2 \times 10^{4}\right)} \times\left(2.2 \right)

Using exponent rule: \frac{a^m}{a^n} =a^{m-n}

$\Rightarrow\frac{\left(4.8 \times 10^{2-4}\right)}{1.2} \times 2.2

$\Rightarrow\frac{\left(4.8 \times 10^{-2}\right)}{1.2} \times 2.2

Since \frac{4.8}{1.2}=4

$\Rightarrow(4 \times 10^{-2})\times 2.2

$\Rightarrow 8.8 \times 10^{-2}

Hence the value of the expression is 8.8 \times 10^{-2}.
