Given:

The expression is:

\sqrt[3]{\dfrac{-512}{729}}

To find:

The value of the given expression.

Solution:

We have,

\sqrt[3]{\dfrac{-512}{729}}

It can be rewritten as

=\sqrt[3]{\dfrac{(-8)\times (-8) \times (-8)}{9\times 9\times 9}}

=\sqrt[3]{\dfrac{(-8)^3}{9^3}}        [\because a^ma^n=a^{m+n}]

=\sqrt[3]{\left(\dfrac{-8}{9}\right)^3}        [\because \dfrac{a^m}{b^m}=\left(\dfrac{a}{b}\right)^m]

=\dfrac{-8}{9}        [\because \sqrt[n]{x^n}=x]

The value of given expression is \dfrac{-8}{9}.

Therefore, the correct option is b.

The table of values shown below represents a linear function. Which of these points could also be an ordered pair in the table,
Gennadij [26K]

Answer:

<h3>B</h3>

Step-by-step explanation:

not sure if i am right but go off process of elimination

A is a not it to get slope you need to do Y=Mx+b because the slope should be 1.3 and if you get the deciml form of 3 over 9 it would be 0.75

and if you do same process on all of then you will see it is B

Which relations are functions?<br><br><br><br> Choose all answers that are correct.
-Dominant- [34]
Hello!

In a function, each input has only one output. In A, three has two outputs, 4 and 5, so A is not a function.

In B, you can use something called the vertical line test to see if each x value has one y value as an output. You move an imaginary vertical line across the graph, and if it intersects with two points it is not a function. If we do this on our graph, it will not intersect two points. Therefore, B is a function.

In C, we can see that each input has one output, or there are all different inputs, so C is a function.

For D we can use that vertical line test again. It intersects both the points (-1,1) and (-1,6) so D is not a function

Our final answers are B and C.


I hope this helps!

The radius of the circle below intersects the unit circle at (Three-fifths, four-fifths). What is the approximate value of Theta
Fudgin [204]

The measured value of Theta is  53.1 degrees.

Given

The radius of the circle below intersects the unit circle at (3/5, 4/5).

<h3>What is tan theta?</h3>

The measure of the tan angle is defined as the ratio of perpendicular by the base.

The measure of the tan theta is;

\rm Tan\theta=\dfrac{x}{y}

Where the value of x is 3/5 and y is 4/5.

Substitute all the values in the formula

\rm Tan\theta=\dfrac{x}{y}\\\\\rm Tan\theta=\dfrac{\dfrac{4}{5}}{\dfrac{3}{5}}\\\\\\Tan\theta = \dfrac{4}{5} \times \dfrac{5}{3}\\\\Tan \theta=\dfrac{4}{3}\\\\\theta=tan{-1}(\dfrac{4}{3})\\\\\theta=53. 1 \ degrees\\\\

Hence, the measured value of Theta is  53.1 degrees.
