For the linear equation C = kl, where c, cost is the local variable and it takes 49.4 cents more for a 30 min local call. The dependent variable is the price of a local call.
What is a linear equation?There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.
The equation representing the situation
C = kl
where c depicts the cost and l is the length of call.
The dependent variable is the price of a local call.
The term "mord more" denotes that we are searching for the price difference between a 4 minute call and a 30 minute call, or the price of a 26 minute call.
The cost for 26 minutes will be 49.4 cents.

sequence
The nth term of the given quadratic sequence begins 8, 11, 16, 23, 32, = n² + 7.
What is quadratic sequence?Quadratic sequences are those that contain a word. They are distinguished by the fact that the first differences between terms really aren't equal, but really the second differences between terms remain equal.
What is a quadratic sequence's rule?The difference between each term inside a quadratic series is not equal, but the second difference between every term is equal.
How can you tell whether a sequence is straight or quadratic?A linear sequence is a number pattern that increases or lowers by the same amount each time. The common difference is the amount by which it increases or drops. Quadratic sequence: The difference between every term increases or decreases at a steady rate in quadratic sequence.
According to the given data:Given:
8, 11, 16, 23, 32,
The nth rule is:
n² = 1² , 2², 3², 4² , 5²
n² = 1 , 4 , 9 , 16 , 25
Subtracting the equation:

What is the y -coordinate of the y -intercept of the line?
The y-intercept of the equation of a line in general form is:(0, -c/b) or -c/b
The y-intercept is the point where the graph intersects the y-axis. To graph, any function that is of the form y = f(x) finding the intercepts is really important. There are two types of intercepts that a function can have. They are the x-intercept and the y-intercept. An intercept of a function is a point where the graph of the function cuts the axis.
The y-intercept of a function is a point where its graph would meet the y-axis. The x-coordinate of any point on the y-axis is 0 and we use this fact to derive the formula to find the y-intercept. i.e., the y-intercept of a function is of the form (0, y).
The equation of a straight line in general form is ax+by+c=0. For the y-intercept, we substitute x=0 and solve it for y.
a(0)+ by + c =0
by + c =0
y = - c/b
Thus, the y-intercept of the equation of a line in general form is:(0, -c/b) or -c/b

Write an explicit formula for each sequence. Then generate the first five terms. a₁ = 10, r=-1
The explicit formula for the nth term is a(n) = 10 . (-1)ⁿ⁻¹, while the first five terms are 10, -10, 10, -10, 10
In a geometric sequence, the next term is obtained by multiplying the previous term by a common ratio, usually denoted as r.
The general formula of the nth term of a geometric sequence is:
a(n) = a₁ . r^(n-1)
Here a₁ refers to the first term and r to the ratio.
In the problem, the given parameters are:
a₁ = 10, r = -1
Substitute these into the general formula, we get:
a(n) = 10 . (-1)ⁿ⁻¹
Notice that
(-1)ⁿ⁻¹ = -1 if n-1 is an odd number, or if n is an even number
(-1)ⁿ⁻¹ = 1 if n-1 is an even number, or if n is an odd number
Therefore, the first five terms are: 10, -10, 10, -10, 10

The interior angle measure of a regular polygon is given. Identify the polygon.
108
The regular polygon with an interior angle of measure 108° is a pentagon.
A regular polygon is a polygon that has equal side lengths and equal interior angle measures.
Interior angle of a polygon is the angle inside it that is formed by two adjacent sides. The number of interior angles formed inside a polygon is the same as the number of its sides. Meanwhile, the sum of all the interior angles of any polygon is constant to that polygon and depends on the number of sides.
sum = 180(n - 2)
Using this formula,
sum = 180(n - 2)
where n = number of sides of the polygon = number of interior angles
sum = measure of interior angle x n
108n = 180(n - 2)
108n = 180n - 360
180n - 108n = 360
72n = 360
n = 5
If the polygon has 5 sides and 5 interior angles, then the regular polygon is a pentagon.

Determine whether each sequence is arithmetic, geometric, or neither. Then find the tenth term. -12,-5,2,9,16, . . . .
The sequence -12,-5,2,9,16, . . . .. is an arithmetic sequence and its 10th term is a(10) = 65
To determine whether a sequence is an arithmetic or geometric one, we need to check the relation between two consecutive terms.
In an arithmetic sequence, the nth term is obtained by adding the (n-1)th term with a constant, called a common difference (d).The given sequence is:
-12,-5,2,9,16, . . . .
In this sequence:
a(1) = -12
a(2) = -5
a(3) = 2
a(4) = 9
and so on.
Notice that:
a(2) - a(1) = -5 - (-12) = 7
a(3) - a(2) = 2 - (-5) = 7
a(4) - a(3) = 9 - 2 = 7
Since each consecutive terms have common difference, then, the given sequence is an arithmetic sequence. Furthermore, the common difference, d = 7.
The formula for the nth term in an arithmetic sequence is given by:
a(n) = a(1) + (n - 1) . d
Substitute n = 10, d = 7, and a(1) = -12
a(10) = -12 + (12 - 1) . 7
a(10) = -12 + 77 = 65

The length of the given rectangle is 9.
According to the statement
We have to find that the length of the rectangle.
So, For this purpose, we know that the
A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel.
From the given information:
The width of a rectangle is 8 units less than the length. The area of the rectangle is 9 units
Then
Let the Length of the rectangle = x
Let the width of the rectangle = x-8
Area of the rectangle = L*B
Then
L*B = 9
x(x-8) = 9
x^2 -8x -9 = 0
x^2 -9x + 1x -9 = 0
x(x-9) +(x-9) = 0
(x+1) (x-9) = 0
here x = -1 and then x = 9.
Here neglect x = -1 then

Determine whether the given measures define 0,1,2 , or infinitely many triangles. Justify your answers.
a=25, b=21, m
We can form an endless number of triangles when you are given two sides and no measurement of angle i.e a = 25 , b = 21
For Example -
We can chose the value of angle from 0-360 degrees with side length a = 25 and b =21, how many different triangles are possible to create?
Create one of the triangles with a protractor having the side lengths a = 25 m and b = 21 m and angle 12° and third side can be adjusted to your preferred length. You have built a triangle.
Similarly by changing the length of the third side and measure of the angle we will get an entirely new triangle.
It's important to notice that you choose the side lengths and angle. This suggests that you might make a different decision. By employing the same angles, you were able to make an infinite number of different triangles.
Therefore, with simply the measurements of one angle and a side length, we can create an endless number of triangles.
