In the plane, we have
everywhere. So in the equation of the sphere, we have
which is a circle centered at (2, -10, 0) of radius 4.
In the plane, we have
, which gives
But any squared real quantity is positive, so there is no intersection between the sphere and this plane.
In the plane,
, so
which is a circle centered at (0, -10, 3) of radius .
The current when the resistance is 10 ohms is 24 amps
<h3>What are variations?</h3>Variations are simply data that change in values (i.e. not constant)
<h3>Types of variation</h3>The types of variations are:
- Direct variation
- Inverse variation
- Joint variation
- Combine variation
From the complete question (see attachment), we have the following highlights
- The variation is an inverse variation
- When current (I) is 30 amps, the resistance (R) is 8 ohms
An inverse variation is represented as:
Where k represents the constant of variation.
The above equation can be rewritten as:
So, we have:
When the resistance is 10 ohms, we have:
Divide both sides by 10
Rewrite the above equation as:
Hence, the current when the resistance is 10 ohms is 24 amps
