Answer:
16 units
Step-by-step explanation:
We need to find the distance between (-4, 8) and (12, 8) on the coordinate plane.
We know that the distance between two points on the coordinate plane is given by :
Put x₁ = -4, x₂ = 12, y₁ = 8 and y₂ = 8
So,
So, the distance between the two points is equal to 16 units.
Answer:
The dot product of (7,5) and (-5,4) is -15
Step-by-step explanation:
Given
(7,5) and (-5,4)
