A composite number is a positive integer. which is not prime (i.e., which has factors other than 1 and itself). The first few composite numbers (sometimes called "composites" for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, ... (OEIS A002808), whose prime decompositions are summarized in the following table.
When you're working with units of measure, the prefix 'kilo...'
almost always means '1,000'.
1 kilometer means 1,000 meters
322 (kilometers) per hour means 322 (1,000 meters) per hour.
322 (1,000 meters) = 322,000 meters
Does that help a little bit ?
I think is D hopefully is right
Given that,
An equation : -9c² +2c +3 = 0
To find,
Find the value of x.
Solution,
We have, -9c² +2c +3 = 0
We can solve it using the formula as follows :
Here, a = -9, b = 2 and c =3
Put the values,
So, the solution are -0.47 and 0.69.
