Answer:
30
Step-by-step explanation:
For a = <xa, ya> and b = <xb, yb>, the dot product is the sum of products ...
a·b = (xa)(xb) + (ya)(yb)
Substituting the given information, you have ...
a·b = 5·4 + 2·5 = 20 + 10
a·b = 30
_____
Some graphing calculators can do such math. There are also dot product calculators available on the Internet. If you have quite a few of these to calculate, you can put the appropriate formula into a spreadsheet.

Answer:
4%
Step-by-step explanation:
The unemployment rate is calculated by dividing the number of unemployed(2 million) by the labor force (50million) and multiplying the result by 100.
Labor force is the total number of unemployed and employed persons in a country. In this case, we have:
Labor force= No. of unemployed (in million) + No. of full time employed (in million) + No. of part time employed (in million) = 2 + 38 + 10 = 50 million
Unemployment rate= 2/50 × 100 = 4%
Therefore, the rate of unemployment is 4%.
