Answer:</h2>
The undefined term that is used to define an angle is:
Line.
<h2>
Step-by-step explanation:</h2>
Angle is formed with the help of two lines which are not parallel to each other and intersect at a point.
( Also, such two lines are known as a ray.
Since a ray is a line with one end point and the angle is formed with the help of 2 rays with the same starting or initial point )
From the diagram we may see how the angle is formed.
Hence, the answer is:
Line
The correct answer would be B, -1/6
Answer:
11
Step-by-step explanation:
Constant of proportionality, k, is the ratio of the quantity of variable y to the quantity of variable x.
Using a point on the line, (4, 44),
Constant of proportionality, k = 
.
Constant of proportionality of the graph is 11.
There are three types of progression: arithmetic progression, geometric progression and harmonic progression. Arithmetic progression is a sequence of numbers or variables that has a common difference. Geometric progression has a common ratio, while harmonic progression is just the reciprocal of the sequence in arithmetic progression.
Example of an arithmetic sequence is: 34, 37, 40, 43, 46. The adjacent terms have a common difference of 3. Mathematicians have already derived equations for arithmetic progression so it would be just convenient for us to predict the next numbers or missing numbers in the sequence. These equations are:
An = A1 + (n-1)d
Sn = (n/2)(A1 + An)
where
An is the nth term in the sequence
A1 is the first term in the sequence
n is the total number of terms int he sequence
d is the common difference
Sn is the sum of all the terms in the sequence
These two equations describe an arithmetic sequence.
Find the rate of change at x=0 and at x=3, then find the average of those values.
f(0) = 2(0) + 1 = 1
f(3) - 2(3) + 1 = 7
Answer: 4
