The answer is C 16:20 because both numbers 4&5 are multiplied by four
Answer:
true
Step-by-step explanation:
2(-2)=-4
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>
Answer:
Step-by-step explanation:
A/4=72/12
A=4(72)/12
A=24 u^2
Answer:
It would be 80 miles in 1 hour
Step-by-step explanation:
You divide 560/7
7 goes into 56, 8 times and into 0, 0 times.
560/7=80
