The median is the number in the middle of a list of numbers.
Since this list has an even amount of numbers, you take the 2 middle numbers, add it together, and divide by 2 to get the average value.
The middle values are 17 and 20, so you do:
17 + 20 = 37 now divide by 2
37/2 = 18.5
Answer:no idea cause we can’t see what or where m is
Step-by-step explanation:but if two rays are perpendicular then they intersect at 90 degrees and the slope of ray1 =m1 and the slope or ray2 = m2 and m1 x m2 =-1
Answer:
see below for drawings and description
Step-by-step explanation:
For geometry problems involving translation, rotation, and reflection—transformations that change location, but not size ("rigid" transformations)—it might be helpful for you to trace the image onto tracing paper or clear plastic so that you can manipulate it in the desired way. Eventually, you'll be able to do this mentally, without the aid of a physical object to play with.
For the images attached here, I copied the triangle onto a piece of clear plastic so I could move it to the desired positions. The result was photographed for your pleasure.
__
a. Translation means the image is moved without changing its orientation or dimensions. You are asked to copy the triangle so that the upper left vertex is moved to what is now point E. See the first attachment.
__
b. Reflection means the points are copied to the same distance on the other side of the point or line of reflection. Just as an object held to a mirror has its reflection also at the mirror, any points on the line of reflection do not move. Reflection flips the image over. See the second attachment.
__
c. Rotation about point D means point D stays where it is. The angle of rotation is the same as the angle at D, so the line DE gets rotated until it aligns with the line DF. The rest of the triangle maintains its shape. See the third attachment.
Answer:
The Answer is approximately: 20.22
Step-by-step explanation:
The distance formula is:
d = Sqrt ((x - x1)^2 + (y - y1)2)
The points are (5, -14), (-15, -17)
d = Sqrt ((5 - (-15))^2 + (-14 - (-17))^2)
d = Sqrt ((5 + 15)^2 + (-14 + 17)^2)
d = Sqrt (20^2 + 3^2)
d = Sqrt (400 + 9)
d = Sqrt (409) = 20.22
