U . v = |u| . |v| cos 60 = 10 * 8 * 0.5 = 40 This is called the scalar (or dot) product.
Answer:
1/2
Step-by-step explanation:
3/4+3/8=9/8
9/8-5/8=1/2

Answer:
3. The sequence is not arithmetic because the terms do not have a common difference.
Step-by-step explanation:
These are ordered pairs in the form of (x, y), so I'll write them here with just the y from least to greatest so it's easier to read:
1, 4, 9, 16, 25
The 3 answers are:
- The sequence is arithmetic because the terms do not have a common difference.
- The sequence is not arithmetic because the terms have a common difference.
- The sequence is not arithmetic because the terms do not have a common difference.
First, look at the difference between each of the terms.
![4-1=3\\9-4=5\\16-9=7](https://tex.z-dn.net/?f=4-1%3D3%5C%5C9-4%3D5%5C%5C16-9%3D7)
Second, an arithmetic sequence is a sequence where each consecutive term has a common difference over the last.
Finally, that leaves only answer 3. The sequence is not arithmetic because the terms do not have a common difference.
Answer:
Whole Numbers
Step-by-step explanation:
whole numbers are just the counting numbers starting from zero: 0,1,2,3...
integers are whole numbers with negatives: ...-3,-2,-1,0,1,2,3...
rational numbers are any numbers that can be expressed as fractions:
2/3, 5, -3, -12/3,4,5,0....
irrational number are numbers that can't be expressed as fractions, which means that they are never-ending decimals.
Hope this helps!
