Answer:
x = 13, y = 7
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, thus
x - 7 = 6 ( add 7 to both sides )
x = 13
and
2y - 6 = 8 ( add 6 to both sides )
2y = 14 ( divide both sides by 2 )
y = 7
Answer:
The assignment of teachers to students enrolled in each of their classes is NOT an example of a function.
Step-by-step explanation:
To determinate if the given example is a function, you have to use the definition of function and compare it to the example.
A function is defined as a relation that assigns each element of one set to exactly one element of the second set. The first set is called the domain and the second set is called the range.
In this case, the domain is represented by the teachers and the range is the students enrolled in each teacher's classes.
Therefore, the example is not a function because each teacher is not assigned to exactly one student. In other words, in general, one teacher has more than just one student.
Answer:
24+6pi
Step-by-step explanation:
the sides on the left and right added up are
12+12=24.
the formula for perimeter of a circle is 2πr.
3 is the radius, making the equation
2π3 which is 6 pi.
for the top semicircle, the perimeter would be 6 pi divided by 2 because its a semicircle.
the bottom cut out half would also be 3 pi.
in total, we would have 24+3pi+3pi which would lead you to 24+6pi.
Answer: X is 3 here. Haven't done this math (don't know how to graph) but I found x so it should be hard from here :)
Good Luck
