How many different combinations can you make?</h3>
To find the total number of combinations, we need to find the number of options for each one of the digits.
There are 4 digits, such that each digit can only be an odd number.
- For the first digit, there are 5 options {1, 3, 5, 7, 9}
- For the second digit, there are 5 options {1, 3, 5, 7, 9}
- For the third digit, there are 5 options {1, 3, 5, 7, 9}
- For the fourth digit, there are 5 options {1, 3, 5, 7, 9}
The total number of different combinations is given by the product between the numbers of options, so we have:
C = 5*5*5*5 = 625.

Answer:
B
Step-by-step explanation:
Just factor it:
5(42 - 12) = 5(30)
You need to convert the cartesian coordinates to polar: This means we need to go from (x, y) --> (r, angle)
We can covert, using the following formulas:
Find r:
r = 4
Now, find our angle:
Use the inverse of tan
Turn 30 degrees to radian
