Determine whether each conjecture is true or false given: n is a real number
Conjecture: n^2 (squared) is a nonnegative number
The conjecture that any real number squared is a nonnegative number is correct. This is because squaring a positive number gives a positive result, squaring a negative number also gives a positive result, and squaring zero equals 0, which is nonnegative.
Explanation:This mathematical conjecture proposes that for any real number, when squared, the result is a nonnegative number. Given n is a real number, the conjecture n^2 is a nonnegative number is indeed true. In mathematics, a real number is considered nonnegative if it is greater than or equal to zero.
To provide more insight, let's look at a few examples: If we take a positive number such as 3, and you square it (3^2), you get 9, which is a positive number. Equally, if you take a negative number like -3 and square it (-3^2), you get 9 again, which is also a positive number. Even if you take the number zero (which is neither positive nor negative) and square it, you get 0, which is still considered nonnegative. Thus, any real number when squared is always a nonnegative number.

Larry Lazy purchased a one year membership at a local fitness center at the beginning of the year. It cost him $150. He goes twice a week for the first three months (13 weeks) of the year, but then goes only once a month for the rest of the year.
How much does each visit to the center cost?
If he continued going twice a week all year, how much would each visit cost?
Answer:
A. $4.29
B. $1.44
Step-by-step explanation:
A. We have been given that Larry goes to gym twice a week for 13 weeks. Let us multiply 13 by 2 to find the number of times Larry visited the gym for first 3 months.
[tex]\text{The number of Larry's visits to gym for the first 3 months}=13\times 2=26[/tex]
Since there are 12 months in a year, then Larry has gone to gym only 9 times for rest of month as 12-3=9.
Now let us add 26 and 9 to get the total number of Larry's visits to gym.
[tex]\text{Larry's total visits to gym}=26+9[/tex]
[tex]\text{Larry's total visits to gym}=35[/tex]
Now let us divide total cost (150) by total number of visits (35) to get the each visit's cost.
[tex]\text{Each visit's cost}=\frac{150}{35}[/tex]
[tex]\text{Each visit's cost}=4.2857142857142857\approx 4.29[/tex]
Therefore, each visit to the center costs $4.29 to Larry.
B. If Larry continued going twice a week all year, then total number of Larry's visits to center will be 52 times 2.
[tex]\text{Larry's total visits to center}=52\times 2[/tex]
[tex]\text{Larry's total visits to center}=104[/tex]
Now let us divide total cost (150) by total visits (104) to find the cost of each visit.
[tex]\text{Each visit's cost}=\frac{150}{104}[/tex]
[tex]\text{Each visit's cost}=1.4423076923076923\approx 1.44[/tex]
Therefore, If Larry continued going twice a week all year, it would cost him $1.44 for each visit.

Alternative Steps
We will use Horner's rule for polynomial division in finding factors as well as divisors.
To begin, let us try x = -2 to see if it is one of the roots of x³ - 11x² + 16x + 84. The complete process can be seen in the attached picture.Since there is no remainder when x³ - 11x² + 16x + 84 is divided by (x + 2), this binomial is a divisor (or a factor). The quotient is obtained x² - 13x + 42.

Translations are part of rigid motions which also include reflection and rotation. For these three, we can then assume that neither the perimeter nor the area of an object would change. This means that, once an object is translated it is not biased or distorted (either enlarged or diminished). Thus, making the perimeter of the original and the image are equal. So for this problem, the perimeter of the image would be the same as the pre-image, and that would be 44 units.
In the context of geometric transformations, the shape and size do not change, only position. Therefore, if the trapezoid's pre-image has a perimeter of 44 units, the image, as a result of translation, will have the same perimeter of 44 units.
Explanation:In the context of geometric transformations like translations, rotations, or reflections, the shape and size of the object do not change--only its position does. The pre-image and the image are congruent, so their perimeters are the same.
In the situation described in your question, Penny's trapezoid is translated so that one of its vertices is at the origin. Because a translation is a type of isometry (a transformation that preserves distance), the shape of the trapezoid and the lengths of its sides will not change in the translation process. As a result, if the perimeter of the pre-image is 44 units, then the perimeter of the image will also be 44 units, regardless of where the vertices are located.

The school bookstore sold 8 more pencils than pens one day. A pencil costs $0.05 and a pen costs $0.20. If the day's sales of pens and pencils totaled $8.90, how many pencils were sold?
To solve this problem, we use algebraic equations to represent the situation. By setting up an equation for the total sales and solving for the number of pens, we can then calculate the number of pencils sold based on the given information. In this case, 34 pens and 42 pencils were sold.
Explanation:Let's solve this problem using algebra. Let the number of pens sold be x. According to the problem, the number of pencils sold is x + 8. Now we can set up an equation to represent the total sales:
0.20x + 0.05(x + 8) = 8.90
Simplifying the equation, we get:
0.20x + 0.05x + 0.40 = 8.90
Combining like terms,
0.25x + 0.40 = 8.90
Next, we can subtract 0.40 from both sides of the equation to isolate x:
0.25x = 8.90 - 0.40
Subtracting, we find that
0.25x = 8.50
Finally, we can divide both sides of the equation by 0.25 to solve for x:
x = 8.50 / 0.25
Calculating, we find that x = 34. This means that 34 pens were sold. Since 34 pens were sold and there were 8 more pencils sold than pens, there must have been 34 + 8 = 42 pencils sold.

1. The tables below show the values of y corresponding to different values of x:
Table A
x 3 2 1
y 1 0 0
Table B
x 3 5 4
y −2 1 1
Which statement is true for the tables?
Both Table A and Table B represent functions.
Both Table A and Table B do not represent functions.
Table A does not represent a function, but Table B represents a function.
Table A represents a function, but Table B does not represent a function.
2. Which of the following statements best describes the effect of replacing the graph of f(x) with the graph of f(x) + 4?
The graph shifts 4 units up.
The graph shifts 4 units down.
The graph shifts 4 units left.
The graph shifts 4 units right.
Both Table A and Table B in the question represent functions, as each x value corresponds to exactly one y value in both tables. The operation of replacing the graph of f(x) with f(x) + 4 results in a vertical shift of the graph 4 units upward.
The subject of the question involves interpreting the data sets presented in Table A and Table B and understanding the behavior of functions. According to the definition, a function is a mathematical relationship wherein each input (x) corresponds to exactly one output (y).
Now, let's determine which tables represent functions. Table A: each 'x' corresponds to exactly one 'y', so this represents a function.
For Table B, each 'x' also corresponds to exactly one 'y', so this also represents a function.
This means both Table A and Table B represent functions.
As for the second question, the operation of replacing the graph of f(x) with f(x) + 4 will result in the graph shifting 4 units upward. The vertical shift is a result of adding 4 to the entire function f(x).
