k=1
Answer:
It's either 400 or 1,200.
Step-by-step explanation:
Other people are saying 400, I got 1,200 by multiplying 1,600 to 0.75 which gave me that answer. I do not know how other people got 400.
Answer:
- Line XY contains ray OX and ray OY
- Line XY contains segment YX
- Ray YX exists in the diagram
Step-by-step explanation:
A ray can be named by any pair of points on an infinite line. Point O, X, and Y on the same line can be used to name rays OX, OY, XY, YX, OY, and XO. The first point named is the end point of the ray. The ray goes through the other point and continues indefinitely.
BA can be the name of a line segment, but not a ray. The line shown does not extend from point B beyond point A.
Any segment can be named by its end points in either order.
So, we have ...
- Line XY contains ray OX and ray OY
- Line XY contains segment YX
- Ray YX exists in the diagram
Answer:
C) ±8/5
Step-by-step explanation:
Both the numerator and the denominator are positive squares (8 is the square root of 64, and 5 is the square root of 25). Finding the square root of both the numerator and the denominator will yield the simplified fraction ±8/5.
Remember: the square roots of a positive square are always both positive and negative. The square root of 
is 2 (
) and -2 (
)
