Answer:
A.6.2i-4.2 j
Step-by-step explanation:
We are given that



We have to find the projection of w on to u.
The project of vector a on b
=


Using the formula
The projection of w on to u

The projection of w on to u=6.2i-4.2j
Hence, option A is true.
The answer is x=5 because 24-3-5=16 so you have to get those 2 sides to equal 16....2*5=10+1=11 then add 5 and you get 16
11= x because if you simply the question you get 13= x+ 2 and then you subtract 2 from each side and cross out the 2 from 2/2 and get left with 11=x
500 * (1+0.0202/12)^60) = 553.09
Answer:
The total number of ways are 315.
Step-by-step explanation:
Consider the provided information.
A certain university will select 1 of 7 candidates eligible to fill a position in the mathematics department.
Therefore the number of ways are:
ways
There are 7 ways to fill math position.
2 of 10 candidates eligible to fill 2 identical positions in the computer science department.
Therefore the total number of ways are:

Hence, there are 45 ways to fill computer science position.
Total number of ways = 7 × 45 = 315 ways.
Hence, the total number of ways are 315.
