Mathematics
1 answer:
Sliva [168]3 years ago
6 0

Answer:

A. All sides of the triangle have the same length.

B. All angles of the triangle have the same measure.

Step-by-step explanation:

A shape is said to have rotation symmetry if after a rotation about a point (center), it fits unto itself. An equilateral triangle has 3 order of symmetry, that is anytime it is rotated, it maps unto itself.

An equilateral triangle is a triangle in which all the sides are equal and all the angles have the same measure of 60° each.

This means that options A and options B are both correct

How do I show the relationship between the input and the output
alexgriva [62]

Answer:

Types of Relationships between the Input and Output

The scatter plot can be a useful tool in understanding the type of relationship that exist between the inputs (X’s) and the outputs (Y’s)

Step-by-step explanation:

1. No Relationship: The scatter plot can give an obvious suggestion if the inputs and outputs on the graph are not related. The points will be scattered throughout the graph with no particular pattern. For no relationship to exist, points have to be completely diffused. If some points are in concentration, then maybe a relationship does exist and our analysis has not been able to uncover it.

2. Linear and Non-Linear: A linear correlation exists when all the points are plotted close together. They form a distinct line. On the other hand points could be close together but they could form a relationship which has curves in it. The nature of the relationship has wide ranging implications.

3. Positive and Negative: A positive relationship between the inputs and the outputs is one wherein more of one input leads to more of an output. This is also known as a direct relationship.

On the other hand a negative relationship is one where more of one input leads to less of another output. This is also known as an inverse relationship.

4. Strong and Weak: The strength of the correlation is tested by how closely the data fits the shape. For instance if all the points are scattered very close together to form a very visible line then the relationship is strongly linear. On the other hand, if the relationship does not so obviously fit the shape then the relationship is weak.

I don't know if this was exactly what you were looking for; hope it is! :)

1) m - 38 = -44 * m = --6 o m = 6 m = 82 O m = --82​
galina1969 [7]

m-38=-44

    +38     +38       add 38 on both sides, solve for -44 + 38 which is -6.

__________

m = -6, is your final answer.

hope this helps :)
