Find the perpendicular line then find the intersection then find the point
perpendicular lines have slopes that are perpendicular
the slopes multiply bo -1
y=mx+b
m=slope
y=2x-3
2 is slope
2 times what=-1
what=-1/2
the equation is
y-3=-1/2(x-8) or
y=(-1/2)x+7
find intersection
at (4,5)
distance bwetweeen (8,3) and (4,5)
D=
D=
D=
D=
D=2√5
distance= 2√5
49
Because 7x7 is 49 & 4+9=13
Answer:
Step-by-step explanation:
Given
Coordinates of Point A is i.e. Point A is 3 units to the left and 4 units below x-axis
From figure, we can write
Answer:
- D. 5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.
Step-by-step explanation:
We are given directions and position change.
This is about the velocity, the speed doesn't take into account the direction.
We also see the change in the velocity. The numbers give us instantaneous velocities and the displacement is the average velocity as the sum of vectors.
Considering the above explanation, correct choice is D.
