A round plane figure whose boundary ( circumference) consists of the points equidistant from a fixed point (the center). In the above question Pedro was wrong.
What is a circle?All the points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in plane draws to keep its distance from a specific point constant.
The tactic Pedro frequently used is ineffective since applying strict transformation to one figure and then onto another will only demonstrate whether the figures are congruent, not whether they are comparable.
Keep in mind that resemblance, as opposed to congruence, is about the proportionality between the dimensions of those figures. Therefore, when we overlay the figures, they won't match.
Pedro should divide each set of matching coordinates to demonstrate similarity; if all divisions provide the same outcome, the figures are said to be comparable.
Therefore, Pedro was not wrong.

29 less than -10 times a number is equal to -18 times the number plus 91
Answer:
-10x - 29 = -18x + 91
x = 15
Step-by-step explanation:
29 less than -10 times a number is equal to -18 times the number plus 91:
-10x - 29 = -18x + 91
add 21 to both sides:
-10x - 29 + 29 = -18x + 91 + 29
-10x = -18x + 120
add 18x to both sides:
-10x + 18x = -18x + 120 + 18x
8x = 120
divide both sides by 8:
8x/8 = 120/8
x = 15

"if i flip a coin, i have a 50 percent chance that it will land on heads." in this statement, even after the first coin flip, we still have a 50 percent chance that the next flip will result in a head. this statements interprets "probability" as:
The probability of getting heads on both occasions will be 0.25.
How to calculate the probability?It should be noted that probability simply means the likelihood that a particular event will happen.
In this case, if I flip a coin, i have a 50 percent chance that it will land on heads and after the first coin flip, we still have a 50 percent chance that the next flip will result in a head.
The probability will be:
= P(head) × P(head)

A new television set was recently purchased for the common room in a residence hall for $520.00 including tax. If the tax rate is 4%, find the price of the television set before taxes.
Let's use the variable x to represent the price of the television set before taxes.
If the tax rate is 4%, then the original price is multiplied by 1.04, so it is equal 1.04x.
The final price is $520, so we have:
[tex]\begin{gathered} 1.04x=520 \\ x=\frac{520}{1.04} \\ x=500 \end{gathered}[/tex]So the price before taxes is $500.00.

what is the equation of a line that is parallel to line y=3x+5 and goes through the point (6,-7)
The equation of a line that is parallel to line y=3x+5 and goes through the point (6,-7) is y = 3x + 2
What is equation of line ?A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system. The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line. Any line's equation can be used to determine whether a given point is on the line or not.A linear equation with a degree of one is the equation for a line.
Given that : the equation of a line is parallel to line y=3x+5 and goes through the point (6,-7)
y=3x+5 is the equation for the given line.
This type of line is called a slope intercept. The line has a slope of m=3.
The slope of parallel lines is equal. As a result, all lines with slope m=3 will be perpendicular to one another.
y=3x+2 is an example of a line that is parallel to the supplied line.

Find the measure of each arc. For each arc, write two or more complete sentences explaining which theorem or postulate you used to find your answer. Include your equations and calculations in your final answer.
m arcRPQ
Answer:
arc RPQ = 305°
Step-by-step explanation:
• the angle at the centre is equal to the measure of the arc that subtends it.
arc RP = ∠ ROP = 125°
∠ QOS and ∠ ROP are vertically opposite angles and are congruent, so
∠ QOS = 125° and so arc SQ = 125°
RS is a straight angle , then
∠ POS = 180° - 125° = 55°
arc PS = 55° ( arc subtending the angle at centre
Then
arc RPQ = RP + PS + SQ = 125° + 55° + 125° = 305°

Our function is a parabola, therefore, it has only one critical point which is its vertex. Since the coefficient of the squared term is negative, the vertex is the maximum point.The critical points of a function are given by the zeros of the first derivative. The first derivative of our function is:
[tex]f^{\prime}(x)=-6x-18[/tex]The solutions for the following equation are the critical points of the original function:
[tex]-6x-18=0\implies x=-3[/tex]The maximum point happens at x = - 3.
To find the corresponding value, we just have to evaluate x = - 3 into our function:
[tex]f(-3)=-3(-3)^2-18(-3)-26=1[/tex]The maximum value of the function is 1, and it occurs at x = - 3.
Answer: The function has a maximum value
The function's maximum value is 1
The function's maximum value occurs at x=-3
Step-by-step explanation:
Given equation: [tex]g(x) = -3x^ - 18x - 26[/tex]
We shall use the differentiation method to find the answer.
Differentiating the equation, we get [tex]g'(x) = - 6x - 18[/tex]
equating g'(x) = 0,
[tex]-6x - 18 = 0\\-6x = 18 \\x = -3[/tex]
Hence the minimum/ maximum value of the function lies in x = -3
on equating x>-3, g'(x) is negative
on equating x<-3, g'(x) is positive
this proves that first, the function was increasing and after x = -3, the function started to decrease hence at x=-3, the function g(x) was at its maximum value
The function's maximum value at x=-3 is
[tex]g(x) = -3x^2 - 18x - 26\\g(-3) = -3(-3)^2 - 18(-3) - 26\\g(-3) = -3(9) +54 -26\\g(-3) = 54 - 27 -26\\g(-3) = 1[/tex]

The slope of AB = 2
The slope of CD = 2
Both lines are parallel lines.
How to Determine Parallel and Perpendicular Lines?The lines that are perpendicular to each other have slope values that are negative reciprocal of each other.
For example, if the a line's slope is a, the line that is perpendicular to it will have a slope of -1/a. This is because the negative reciprocal of a is -1/a, and (a)(-1/a) = -1.
On the other hand, the lines that are parallel to each other will have the same slope value.
Given the following:
A(−6 , −9)
B(8, 19)
C(0, −4)
D(2, 0)
Find the slope (m) of AB:
Slope of AB = (19 -(-9))/(8 -(-6))
Slope of AB = 28/14
Slope of AB = 2

Slope of CD = (0 -(-4))/(2 - 0)

Kylie just accepted a job at a new company where she will make an annual salary of $67000. kylie was told that for each year she stays with the company, she will be given a salary raise of $3000. how much would kylie make as a salary after 3 years working for the company? what would be her salary after tt years?
Since the situation can be since as an arithmetic sequence, her salary after 3 years is $73,000. After t years, her salary is a function of t, that is a(t) = 64000 + 3000 t
The given situation can be seen as an arithmetic sequence. The nth term of an arithmetic sequence is given by the formula:
a(n) = a(1) + (n - 1) . d
Where:
a(1) = the first term
d = the common difference.
The problem can be translated into an arithmetic sequence with:
a(1) = $67000
d = $3000
Kylie's salary after 3 years is a(3),
a(3) = a(1) + (3 - 1) . d
a(3) = Kylie's salary + 2 . 3000 = 73000
Hence, after 3 years, Kylie's salary is $73,000
Her salary after t years, means n = t. Therefore,
a(t) = a(1) + (t - 1) . d
a(t) = 67000 + (t -1) . 3000
a(t) = 64000 + 3000 t
