By definition we have to:
A mathematical function is a relationship that is established between two sets, through which each element of the first set is assigned a single element of the second set or none.
The initial set or starting set is also called the domain; the final set or set of arrival, meanwhile, can be called codomain.
We have the following information:
{(-5.2), (-2.5), (0.7), (0.9)}
The data does not represent a function because two different values of the range belong to an element of the domain:
(0.7)
(0.9)
Answer:
The relation is not a function.
1. m= 1/2
2. x=-2
hope this helps!
Answer:
the value of x is 25 degrees
Step-by-step explanation:
Here, we want to get the value of x
we use an important triangle angular principle here
And the principle is that when we add two opposite interior angles, we get the value of the exterior angle on the third side
Thus, mathematically;
x + 75 = 4x
4x-x = 75
3x = 75
x = 75/3
x = 25 degrees
Since ABC and DEF are similar, with ratio 1:2, it means that the sides of DEF are twice the size of ABC.
So, the perimeter of DEF is twice the perimeter of ABC, which means it is 46.
We can't pick any triplet of numbers that sum to 46 anyway, because in every triangle the sum of two sides must exceed the third one.
So, for example, the sides of DEF can't be 1, 5, 40, because 1+5 < 40.
A good option (although there are infinite possibility) could be for example 15, 11 and 20.
