A unit vector in the direction of a would be the vector a multiplied by a factor such that the length of vector a is unity.
The magnitude of a is given by:
|a|
=sqrt(4^2+3^2+2^2) [ I got lazy instead of writing (-4)^2+(-3)^2+2^2]
=sqrt(29).
So the univector is a/sqrt(29), or (-4/sqrt(29),-3/sqrt(29), 2/sqrt(29), or simply (-4,-3,2)/sqrt(29).
Answer:
Step-by-step explanation:
-19=-17+k/5
add 17 to both sides
-2=k/5
multiply by 5 on both sides to get k alone
k=-10
You have to use the Pythagorean theorem because it is a right triangle. Consequently it is the square root of 12 squared plus 17 squared or approximately 20.81

3.14 x 3.5 x 3.5 x 10 = 384.65
3.14 x 2 x 2 x 6 = 75.36
Answer:
Yes, any whole number is rational
Step-by-step explanation:
1, 2, 3, 4... etc is rational
1.5, 2.5, 3.5, 4.5...etc is irrational
I hope this helps you :)
