Answer:
Step-by-step explanation:
The volume of a cone can be found with the following equation:

where
is the radius of the base and
is the height of the cone.
For the cone with diameter of 20 units and height of 12 units, the volume is the following:



For the cone with diameter of 18 units and height of 10 units, the volume is the following:



For the cone with diameter of 20 units and height of 12 units, the volume is the following:



The trigonometric form of the complex number given in the task content is; 18(isin(π/2)).
<h3>What is the trigonometric form of the complex number?</h3>
If follows from the task content that the complex number whose trigonometric representation is to be determined is; 18i.
Hence, It follows that the trigonometric form is;
= 18(cos(π/2) + isin(π/2)). where; cos(π/2) = 0.
Hence, we have;
= 18(isin(π/2)).

Answer: Inconsistent.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
Solve for "y" in each equation:
<em>Equation 1</em>

<em>Equation 2</em>
<em>
</em>
<em> </em>
You can notice that the slope of the <em>Equation 1 </em>is:

And the slope of the <em>Equation 2 </em>is:
Observev that
, then you can conclude that the lines are parallel and the System of equations has No solution.
When there is no solution the classification of the system of equations is: "Inconsistent".
