You have two vectors: 
and 
In order to find the sum 
of vectors 
and 
, you should add corresponding coordinates:
Answer: correct choice is C.
The next larger thousand is 192,000 .
The next smaller thousand is 191,000 .
191,306 is closer to 191,000 than it is to 192,000 .
So the nearest thousand is 191,000 .
Angle A is 78 because Ab is equal to the Ac
Answer:
im sorry but i think it is 4
Step-by-step explanation:
Step-by-step explanation:
The slope of a line connecting two points is:
m = (y₂ − y₁) / (x₂ − x₁)
The slope of line 1 is:
m = (4 − 0) / (7 − 1)
m = 2/3
The slope of line 2 is:
m = (6 − 0) / (3 − 7)
m = -3/2
Parallel lines have equal slopes.
Perpendicular lines have opposite inverse slopes.
2/3 and -3/2 are opposite inverses, so the lines are perpendicular.
