Finding the value of x and y.
x:
sin 30 = 1/x
x = 1/sin 30
x = 2
y:
cos 30 = y/2
2(cos 30) = y
1.73 = y
Now the table:
sin 30 = 1/2
cos 30 = 1.73/2
tan 30 = 1/1.73
sin 60 = 1.73/2
cos 60 = 1/2
tan 60 = 1.73/1
Hope this helps :)
If two variables are in direct proportion, then as one increases, the other increases, and as one decreases, the other decreases. An example: If you're working, the amount of money you make (variable y) is in direct proportion to how many hours you work (variable x). The more hours you work, the more money you make, and vice versa. You can put these into the equation y = kx, where k is a constant rate at which x and y are directly proportional.
<span>If two variables are in inverse proportion, then as one increases, the other decreases, and vice versa. For example: if you take unpaid vacation from work, the number of days taken off (variable x) is in inverse proportion to the amount of money you make (variable y). The more vacation you take, the less money you'll make, and vice versa. You can put these into the equation y = k/x, where k is a constant rate at which x and y are inversely proportional.</span>

Answer:
-3/8
Step-by-step explanation:
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
