Answer:
a
Step-by-step explanation:
Given
u = (x₁, y₁, z₁ ) and v = (x₂, y₂, z₂ ) then the dot product is
u • v = (x₁ x₂ ) + (y₁ y₂ ) + (z₁ z₂ )
Then
v • w
= (5 × 9) + (- 4 × - 2) + (4 × 7)
= 45 + 8 + 28
= 81 → a

Hello from MrBillDoesMath!
Answer:
2291/990
Discussion:
Let
x = 2.3141414...... then
10x = 23.141414... (*)
and
1000x = 2314.141414..... (**)
Subtract (*) from (**):
1000x - 10x = (2314 + .141414....) - (23 + .141414....)
990x = 2314 - 23 as the decimal parts cancel
990x = 2291
x = 2291/990
Thank you,
MrB
