Step-by-step explanation:
Given : Expression
To find : The solution for x and identify if it is an extraneous solution?
Solution :
Expression
Taking square both side,
Substituting the value back in the equation to find this is an extraneous solution or not.
This is true.
Which means solution is not an extraneous solution.

Answer:
The angular speed of the wheel in radians per second is 0.66.
Step-by-step explanation:
Recall the following statement:
A linear speed (v) is given by,
...... (1)
Here, represents the angular speed of the wheel and <em>r</em> represents the radius of the wheel.
From the given information:
Linear speed (v) = 33 cm/s
Radius of the wheel (r) = 50 cm
Now to find the angular speed in radian per second.
Divide both sides by 50.
Hence, the angular speed of the wheel in radians per second is 0.66.
Answer:
<em>The compound inequality that shows the voltage amount the necessary range is </em>
Step-by-step explanation:
Loni needs between 3.5 and 7.2 volts of energy, not inclusive, to make an experiment work correctly.
That means, <u>the voltage amount should be either greater than 3.5 volts or less than 7.2 volts</u>.
Suppose, the amount of voltage is volts to make the experiment work correctly.
Now, Voltage amount is greater than 3.5 volts means: or
and voltage amount is less than 7.2 volts means:
Thus, the compound inequality by combining the above two inequalities will be:
