If represented in a stem and leaf plot, what would be the leaf of the number 329?​
sdas [7]

Answer:

You can either do a back to back stem and leaf plot, where you would have double the values. In a normal stem and leaf plot you would just have one set of 3's where you would put all the values that start with 3 in that column. A back to back is the same but instead you would have two 3 values, where anything that is higher than 5 would be in the second value of 3, but anything lower would be in that first value of 3.

Figure ABCD is transformed to figure A prime B prime C prime D prime, as shown below:
Virty [35]

Using translation concepts, the sequence that is used to obtain the translated image is:

  • Reflection over the y-axis.
  • Shift right of one unit.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

For all the vertices, the transformations follow the given pattern:

  • (x,y) -> (-x,y) -> (-x + 1, y).

In the step (x,y) -> (-x,y), the function is reflected over the y-axis. Then, in step (-x,y) ->  (-x + 1, y), the function is shifted right one unit.
