You have to do exactly what it says calculate the length of that part of the shape.
I think, I'd go with A) Always true. As 2 points is always the line. If you add third one, it will be collinear.
Sqrt ( (-4)^2 + (-sqrt2i)^2 )
= sqrt (16 + 2)
= sqrt 18
= sqrt9 * sqrt 2
= 3 sqrt2 (answer)
Answer:
5) a
6) a
7) b
8) d
9) a
10) b
11) c
12) a
Step-by-step explanation:
When it asks for range it is asking for the y values so when you plug in numbers such as 0,1,2 into the equation the y values you get are {0,90,180..}
Overall slope can be found by taking the x and y values of the two given points.
((y value of the second point)-(y value of the first point))/((x value of the second point)-(x value of the first point))
Using (1,2) and (-2, 5) you can do this by plugin in the numbers (5-2)/(-2-1)
So the slope will be 3/-3 = -1
Once you find the slope you can use this to find the equation of a line by pluging in values into y=mx + b
m = slope
y = use this from the points given
x = use this from the points given
I do not understand what you are asking for
I am assuming you want the missing angle, in this case it is 10
Triangle Sum Theorem states that a triangle is equal to 180 degrees
120+50 = 170
180-170
= 10
