Answer:
a. 
Step-by-step explanation:
The given vector is v= 4i - 5j
The magnitude of this vector is;



The unit vector u in the direction of v is;



We rationalize to get

9.125*x^2 is 100000 times greater than 9.125*10^(-3).
Note that (10^5)(9.125*10^(-3) = 9.125*10^2.
First, add. 11/10 + 23/10 = 34/10
You can then simplify by finding the greatest common factor (2)
34/2, 10/2 = 17/5, or 3 and 2/5

Hello from MrBillDoesMath!
Answer:
Slope = 4/5
Discussion:
Slope = (change in y) / (change in x)
Slope =
(1-5)/(0-5) =
-4/-5 =
4/5
Thank you,
