5. How do you graph a piecewise function?
Answers
To graph a piecewise function, plot the different parts of the function separately based on the specified conditions or intervals, and ensure continuity at the endpoints.
Here's a step-by-step guide on how to graph a piecewise function:
1. Identify the different conditions or intervals: A piecewise function is defined by different equations or expressions for specific intervals or conditions. Identify these conditions or intervals and the corresponding equations for each interval.
2. Plot the intervals on the x-axis: Identify the range of values for the x-axis based on the given intervals. Mark the intervals on the x-axis accordingly.
3. Graph each part of the function: For each interval, graph the corresponding equation or expression. Treat each part as a separate function within its defined interval.
4. Consider the endpoints of each interval: Pay attention to the endpoints of each interval and determine whether they are included or excluded from the graph. Use open or closed circles to represent the endpoints, depending on whether they are included or excluded.
5. Ensure continuity: Check if the function is continuous across the intervals. Make sure there are no gaps or jumps in the graph where the intervals meet.
6. Label the axes and add any necessary annotations: Label the x-axis and y-axis, and add any necessary annotations such as the function name, equation, or any important points or features.
7. Review and refine: Step back and review the graph to ensure accuracy and clarity. Make any necessary adjustments to the graph to improve its presentation.

At 98°F, a certain insect chirps at a rate of 88 times per minute, and at 107°F, they chirp 151 times per minute. Write an equation in slope-intercept form that represents the situation.
Answers
The equation in slope-intercept form that represents the situation is y = 7x - 598
What is slope?The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.
The ordered pair are ( 98, 88) and (107, 151)
Equation of line in slope-intercept form is y = mx + c
at x = 98, y =88
so that by substituting we have,
88 = 98m + c -------------------1
at x = 107, y = 151 and by substituting we have
151 = 107m + c -----------------2
subtract equation 1 from 2
63 = 9m
m = 63/9
m = 7
substitute m = 7 in equation 1
88 = 98(7) + c
c = 88 - 686c
c = -598
substitute m and c for their values equation becomes
y = 7x - 598
In conclusion, the equation in slope-intercept form is y = 7x - 598

How do you solve problems involving sequence? Discuss the mathematics concepts and principles applied when solving problems involving sequence
Answers
Step-by-step explanation:
Sequence is defined as arrangement f numbers in a specific or defined pattern. Sequence are categorized into
1) Arithmetic
2) Geometric
Arithmetic sequence are characterized by their common difference while Geometric sequence are characterized by their common ratio.
Given a sequance of numbers say;
T1, T2, T3...
The first term "a" of the sequence is T1
Common difference d = T2-T1 =T3-T2
Common ratio = T2/T1 = T3/T2
The formula for calculating nth term of an Arithmetic sequence is expressed as;
Tn = a+(n-1)d
a is the first term
n is the number of terms
d is the common difference
The nth term of a Geometric sequence is expressed as;
Tn = ar^{n-1}
r is the common ratio
Numbers are arranged in a sequence when they follow a predetermined or established pattern. Sequences can be divided into
1) Mathematics
2) Graphitic
Geometric sequences are characterized by their common ratio, whereas arithmetic sequences are distinguished by their common difference.
Suppose a sequence of numbers is given;
T1, T2, T3...
The sequence's initial term "a" is T1.
common distinction d = T2-T1 =T3-T2
T2/T1 Common Ratio T3/T2
The following is the formula for finding the nth term in an arithmetic sequence:
Tn = a+(n-1)d
The first term is a.
The number of terms is n.
d is the typical discrepancy
The nth term of a Geometric sequence is expressed as;
\(T_{n} =ar^{n-1}\)

12 people fit comfortably in a 5 x 5 foot square.use this value to estimate of a crowd that is 10 feet deep on both sides of the street along a 1 mil section of a parade route
Answers
Answer:
48 people
Step-by-step explanation:
It states that 12 people fit into a 5 x 5 ft² area.
Here, we are given the length and breath of the side, both 5 ft. And from that, we can estimate the area of the place.
Area of a square is gotten by multiplying both sides together, and thus
5 * 5 = 25 ft²
We are told 12 people fit into 25 ft². In order to get the number of people that fit a 10 x 10, we first need to calculate the area.
We already have the length and breadth to be 10 ft each, so
Area = 10 * 10 = 100 ft²
Now, we calculate.
If
12 people fit into 25 ft²
x people will fit into 100 ft²
If we cross multiply, we have
1200 = 25x
We then divide both sides by 25
x = 1200 / 25
x = 48
Therefore, 48 people will fit into a 10 x 10 ft area

The perimeter of the rectangle below is 16 cm. What is the value of k? 5 cm kcm Not to scale
Answers
Answer:
3 cm.
Step-by-step explanation:
Let's use the formula for the perimeter of a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.In this case, we have:P = 16 cm (given)
l = k cm (given)
w = 5 cm (given)Substituting these values into the formula, we get:
16 cm = 2(k cm) + 2(5 cm)
Simplifying, we get:
16 cm = 2k cm + 10 cm
Subtracting 10 cm from both sides, we get:6 cm = 2k cm
Dividing both sides by 2, we get:
3 cm = k
Therefore, the value of k is 3 cm.

Use Lagrange multipliers to find the dimensions (in meters) of a rectangle with perimeter 120 m whose area is as large as possible. (Enter the dimensions as a comma-separated list.) m
Answers
The dimensions of the rectangle with the largest possible area are 30 meters by 20 meters.
We can use Lagrange multipliers to find the dimensions of the rectangle with the largest possible area. The area of the rectangle is given by A = lw, where l is the length and w is the width. The perimeter is given by P = 2l + 2w = 120. We can use Lagrange multipliers to find the critical points of the function A, subject to the constraint P = 120. This gives us the following equations:
λ = 2l / A
λ = 2w / A
Solving these equations, we get the following values for l and w:
l = 30
w = 20
Therefore, the dimensions of the rectangle with the largest possible area are 30 meters by 20 meters.
Here is a diagram that illustrates the solution:
Rectangle with dimensions 30 meters by 20 meters.

Which equation represents a line passing through the points (0, 1) and (2, -3)?
Answers
The equation of the line passing through the points (0, 1) and (2, -3) is y = -2x + 1.
What is the equation of the line?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
First, we determine the slope of the line.
Given the two points are (0, 1) and (2, -3).
We can find the slope of the line by using the slope formula:
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values, we get:
m = (-3 - 1) / (2 - 0)
m = -4 / 2
m = -2
Using the point-slope form, plug in one of the given points and slope m = -2 to find the equation of the line.
Let's use the point (0, 1):
y - y₁ = m(x - x₁)
y - 1 = -2(x - 0)
y - 1 = -2x
y = -2x + 1
Therefore, the equation of the line is y = -2x + 1.

y = -3x - 1
y = -1/3x - 1
y = 3x - 1
Answers
Answer:
y = -3x - 1
Step-by-step explanation:
-1 is the slope intercept, as you can see where the line goes through the y-axis.
The line is also negative, as it's going down, and the slope is three down (negative) and one over. Since slope is written as y over x (y/x), 3 is y. One, the x, doesn't need to be written because 3 is already a whole number.

If A is symmetric matrix, then A^3 is a _______ matrix.
Answers
If A is a symmetric matrix, then A³ is also a symmetric matrix.
To prove this, we can use the definition of a symmetric matrix, which is a matrix that is equal to its transpose. In other words, if A is a symmetric matrix, then A = A^T.
Now, let's look at A³:
A³ = A * A * A
We can replace each A with A^T, since they are equal:
A³ = A^T * A^T * A^T
Now, we can use the property that the transpose of a product of matrices is equal to the product of their transposes in reverse order:
A³ = (A^T * A^T * A^T)^T
A³ = (A^T)^T * (A^T)^T * (A^T)^T
Since the transpose of a transpose is the original matrix, we can simplify:
A³ = A * A * A
Therefore, A³ is also a symmetric matrix.
