Question 4
The magnitude;
Using Pythagoras theorem,
(-200)² + (-530)² = 320900
Length = √320900
= 566.5 mi
To get the angle
Tan θ = opposite/adjacent
= 200/530
= 0.3774
θ = tan^-1 (0.3774)
= 20.67
≈ 21°
The direction from the Cartesian plane is south of west.
Therefore, the magnitude and the direction will be;
About 566.5 mi, 21° south of west
Question 5.
To get the resultant of two vectors we just add the two vectors given.
This involves adding the corresponding values.
Thus, for <-6,5> and <6,-5>
Resultant vector = <(-6+6),(5+-5>
= <0,0>
A) F(3)=3^2-3:3= 9-3:3=9-1=8
B) ?
C) F(11)= 11^2-3:3=121-1= 120
I think this
Really? its .1000 it goes like this "1" is the tenths the "3" is the hundredths the "2" the thousands "5" ten-thousands<span />
