Answer:
The correct option is c.
Step-by-step explanation:
Given that,
u = 7i+4j and v = 2i-3j
We need to find the product of u and v. The dot product of two vectors is given by :

So, the dot product of u and v is equal to 2.
Answer:
30% of employees work part-time
Step-by-step explanation:
i just added 9 and 21 which is 30 and then i figured out that 9 is 30% of 30
The order of the 3 books does not matter so its the number of combinations of 3 from 45
b is the correct choice
For this case we have the following inequality:
2 ≥ 4 - v
The first thing we must do in this case is to clear the value of v.
We have then:
v ≥ 4 - 2
v ≥ 2
Therefore, the solution set is given by:
[2, inf)
