Rozalie spent $26.75 at a parking garage in downtown Orlando. The garage charged a base fee of $7.50 for the first hour, and an hourly rate of $2.75 for each additional hour. The following sign is displayed to show the prices for the first 4 hours.
Answers
Answer:
Rozalie spent 7 hours at the parking garage.
Step-by-step explanation:
The equation for the above Question can be given as:
$7.5 + 2.75x
Where x = hourly rate
We are told that Rozalie spent $26.75
The number of hours Rosalie spent at the parking garage is calculated as:
$7.5 + 2.75x = $26.75
2.75x = $26.75 - $7.5
2.75x = 19.25
x = 19.25/2.75
x = 7 hours
Therefore the number of hours Rozalie spent at the parking garage was 7 hours.

Karina and Perry are cleaning up litter in the park for community service hours. Karina and Perry both claim they have covered the greatest area. Who is correct? Justify your answer using mathematical reasoning. Also, what is the area of both shapes?
Answers
Answer:
a. Perry covered a larger area
b. Karina covered an area of 9 units squared
Perry covered an area of 18 units squared
Step-by-step explanation:
Here, we are to justify our answer using mathematical reasoning.
Firstly, we need to deduce who out of the two has covered the greatest area.
The best way to go about this is by looking at the dimensions of the shapes in which they have individually covered.
For Karina, we have a square of sides 3 units by 3 units
While for Perry, we have a rectangle of dimension 9 units by 2 units
We know that judging by the areas of both, a square of side 3 by 3 has a smaller area compared to a rectangle of side 9 by 2
So since the rectangle has the bigger area, then Perry has covered a larger area during her community service
We are told to calculate the areas;
For Karina , we have;
3 by 3 = 3 units * 3 units = 9 units squared
For Perry, we have
9 by 2 = 9 units * 2 units = 18 units squared

What is Distance?The length along a line or line segment between two points on the line or line segment.
Distance=√(x₂-x₁)²+(y₂-y₁)²
A number line is a horizontal line that has equally spread number increments.
On the number line K is over -9 and L is over 15
We need to find the distance of KL.
KL=OL-OK
Where the OL is 15 and OK is -9.
Now plug in these values in KL
KL=15-(-9)
When minus and minus are multiplied we get positive.
=15+9
Add fifteen and nine we get twenty four.
=24
Hence, if the point K is over -9 and L is over 15 then the value of KL is 24.

m∠1=(50x)∘, m∠8=150°
Answers
Answer:
Alt. Ext. Angles Theorem.
m∠1 = 150
Step-by-step explanation:
∠1 and ∠8 are alternate exterior angles formed when the transversal line cuts across the 2 parallel lines. According to the alternate exterior angles theorem, both are congruent. Therefore,
m∠1 = m∠8
m∠1 = (50x)°
m∠8 = 150
Set both equal and solve for x
50x = 150
Divide both sides by 50
50x/50 = 150/50
x = 3
Unknown angle:
m∠1 = (50x) = 50*3 = 150°

Reflect on the concept of polynomial and rational functions. What concepts (only the names) did you need to accommodate these concepts in your mind? What are the simplest polynomial and rational function you can imagine? In your day to day, is there any occurring fact that can be interpreted as polynomial and rational functions? What strategy are you using to get the graph of polynomial and rational functions?
Answers
Answer:
Given below
Step-by-step explanation:
A rational function is a function containing rational numbers.
It can be an algebraic function in which both the numerator and denominators can be polynomials.
Any number which can be expressed in the form of a fraction p/q where p and q are integers and q is not equal to zero is called a rational number. Positive integers, negative integers ,zeros and common fractions belong to the system of rational numbers. P can be equal to zero.
A polynomial function is a function consisting of polynomials. A polynomial is an algebraic expression consisting of one or more terms in each of which the exponent of the variable is zero or positive integer. Thus 2,3x, x²+ 3x-4 etc are polynomials.
A polynomial consisting of a single term is monomial e.g, 2, 3x , xy
A polynomial consisting of two terms is binomial e.g, 2+3x , xy- 5z etc.
A polynomial consisting of three terms is trinomial e.g, 2+3x +xy
Terms containing the same variable and same corresponding exponents are known as like terms.
Terms having different variables or same variable but different exponents are called unlike terms.
Polynomials are used to sketch curves or daily life problems.
To sketch the graphs first we find the intercepts, then the vertical asymptotes and the horizontal asymptote, by solving.
The vertical asymptotes divide the number line into regions after which the graph is sketched.
The first thing that comes to the mind is the form of p/q for rational functions and algebraic expressions for the polynomial functions.
The fundamental difference between the graphs of the polynomial function and rational function is that the graph of the polynomial function is continuous in nature while the graph of the rational function is discontinuous in nature as the denominator will be zero at some point.
The strategy are using to get graph of polynomial and rational function given below.
Polynomial is an expression comprising variables and coefficients.
The rational expression is fractions involving polynomials
Polynomial: A polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
An example of a polynomial of a single indeterminate, x, is x² − 4x + 7
Polynomial Function : A polynomial function is a function which involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation
Rational: The definition of rational is something that makes sense or that could be based in fact or someone who behaves and thinks logically.
Rational Function: A rational function is any function which can be defined by a rational fraction, i.e. an algebraic fraction such that both the numerator and the denominator are polynomials. The coefficients of the polynomials need not be rational numbers; they may be taken in any field K.
Polynomials are used to describe curves of various types, people use them in the real world to graph curves. For example, roller coaster designers may use polynomials to describe the curves in their rides.
Process for Graphing a Rational Function and Polynomials given below.
Find the intercepts, if there are anyFind the vertical asymptotes by setting the denominator equal to zero and solving. Find the horizontal asymptote, if it exists, using the fact above.The vertical asymptotes will divide the number line into regions.Sketch the graph.The fundamental difference between the graphs of the polynomial function and rational function is that the graph of the polynomial function is continuous in nature while the graph of the rational function is discontinuous in nature as the denominator will be zero at some point.

Step-by-step explanation:
Recall that for a reflection of the triangle, we proceed to reflect its vertices across the given line. A reflection places the image of the three vertices at exactly the same number of units on the other side of the line as the original vertex was.
Please see attached image for description.
We go from vertex A straight perpendicular towards the line, and count two divisions to reach the line, so we move in the exact same down direction two divisions on the other side of the given line and mark its image (point A').
We do similarly with point B (six divisions to reach the given line, and continue also 6 divisions to the other side to create its image B'.
Finally vertex C is 5 divisions from the given line, and we continue 5 divisions on the other side of the line to place its image.
Once this is done, we simply join the image points with segments to form the triangle.
