Answer:
Dilation : The meaning of Dilation is that by taking a fixed center and certain real number we can either enlarge an image or reduce it's size without actually changing it's shape. it totally depends on amount by which we are dilating if it is a real number greater than 1 the size of image increases otherwise shrinks means smaller in size.
The original image is called Pre-image and after dilation that changed image is called image.
So, we can say that Dilation is a function because for each different scale factor or different real number we get different images.
So, Out of all the four options given first looks completely true about Dilation.
i.e A dilation is a function because every point on the pre-image corresponds to exactly one point on the image.
A dilation is a function because every point on the pre-image corresponds to exactly one point on the image. This is the definition of a function in mathematics. The scale factor and the congruity of the image to the pre-image are irrelevant to the classification of dilation as a function.
Explanation:The correct statement is:
A dilation is a function because every point on the pre-image corresponds to exactly one point on the image
. In mathematics, dilation is a transformation that changes the size, but not the shape, of a figure. For a dilation to qualify as a function, each point in the pre-image must correspond to exactly one point in the image, without any point in the pre-image being mapped to more than one point in the image. This is the definition of a function: a relation from a set of inputs (the pre-image) to a set of possible outputs (the image) where each input is related to exactly one output. The scale factor and the congruity of the image to the pre-image have no bearing on whether a dilation is a function or not.

A car travels the 120 miles from A to B at 60 miles per hour, and then returns to A on the same road. If the average rate of the round trip is 45 miles per hour, what is the rate, in miles per hour, of the car traveling back from B to A?
Outbound Trip 120 miles 60 mph equals 2 hours
Return Trip 120 miles
Total Trip 240 miles at 45 mph average speed
Total time = distance / rate = 240 / 45 = 5.3333333333 Hours
The return trip of 120 miles takes (5.3333333333 Hours MINUS 2 hours)
Return Trip Speed = 120 / 3.333333333 = 36 miles per hour
The car's speed on its return trip from B to A was approximately 36mph, based on the given average round trip speed and the speed of the trip from A to B.
Explanation:The subject of this question is the calculation of an unknown speed during a return trip. Let's first calculate the total time of the round trip. The time taken to journey from A to B (we'll call this 'Time1') can be calculated by distance/speed, which equals 120 miles / 60mph, and that equals 2 hours.
The total round trip time (we'll call this 'Total Time') can be calculated by distance/speed, which equals 240 miles / 45mph, and that equals roughly 5.33 hours.
The time taken to return from B to A (we'll call this 'Time2') is the difference between 'Total Time' and 'Time1', which equals roughly 5.33 hours - 2 hours, equaling 3.33 hours.
The speed on the return trip ('Speed2') is the distance divided by Time2, so 120 miles / 3.33 hours equals approximately 36 miles per hour.

this is a side view of a roller coaster. (see attached image.)
-what is the slope between point c and point d?
-what is the equation of the line that represents the climb from point c to point d? using mx+b.
-what is the domain and range for the roller coaster?
Let every line = 1 unit:
Point C is located at (0,0)
Point D is located at (7, 12)
The slope is the change in Y over the change in X:
Slope = 12-0 / 7-0 = 12/7
The equation of the line from C to D using mx +b:
m = slope, which we already calculated as 12/7
To solve for b, replace m with 12/7 to get
y=12/7x +b
replace x with 0 ( from point C )
y = 12/7(0) +b
Replace y with 0 (also from point C)
0 = 12/7(0)+b
Solve for b:
b = 0
The equation becomes y= 12/7x
The Domain is the X values, which range from A to E, -12 to 13
Which is written as (-12,13) or -12≤x≤13
The range is the Y values, which range from A to D, 0 , 12
Which is written as (0,12) or 0≤y≤12

Step-by-step explanation:
An elevator can safely lift at most 4400 lbs. A concrete block has an average weight of 41 lbs. What is the maximum number of concrete blocks that the elevator can lift?
Final answer:
The maximum number of concrete blocks that the elevator can lift is 107.
Explanation:
To find the maximum number of concrete blocks that the elevator can lift, we need to divide the maximum weight the elevator can lift by the weight of each concrete block.
Maximum weight the elevator can lift = 4400 lbs
Weight of each concrete block = 41 lbs
Now, we can use the division operation to find the maximum number of concrete blocks:
Maximum number of concrete blocks = 4400 lbs ÷ 41 lbs ≈ 107.317
Since we cannot have a fraction of a concrete block, we can conclude that the maximum number of concrete blocks that the elevator can lift is 107.

Which statement is false?
A. The number zero is a rational number.
B. Some irrational numbers are also rational numbers.
C. Every irrational number is a real number.
D. Every integer is a rational number.
Need answers ASAP, Thanks!
The false statement is B: 'Some irrational numbers are also rational numbers.' This is incorrect because a number cannot be both rational and irrational by definition.
The false statement among the options provided is option B: Some irrational numbers are also rational numbers. This is false because by definition, irrational numbers and rational numbers are distinct sets of numbers with no overlap. A rational number can be written as a ratio of two integers, which means it can be expressed as a fraction. On the other hand, an irrational number cannot be written as a ratio of integers. Thus, a number cannot be both rational and irrational at the same time.
To clarify the other options, option A is true because zero can be represented as the ratio 0/1, making it a rational number. Option C is true because irrational numbers such as π (pi) and √2 (the square root of 2) are indeed part of the set of real numbers. Option D is true because all integers can be expressed as a ratio where the denominator is 1, making every integer a rational number.
How you can find the common factors and the greatest common factor of two numbers
One way is to create a factor tree for each number. Then see which factors they have in common.
Example:
12 30
^ ^
2 6 3 10
^ ^
2 3 2 5
The factors are the underlined numbers above:
12: 2 x 2 x 3
30: 2 x 3 x 5
The common factors are: 2, 3, and 6 why 6? because 2 x 3 = 6
The greatest common factor is: 6
To find the common factors and the greatest common factor (GCF) of numbers, list all factors of each number, find the common ones, and identify the largest as the GCF. The factor-label method can simplify locating the GCF.
Explanation:To find the common factors and the greatest common factor (GCF) of two numbers, you start by listing all the factors of each number. These are whole numbers that can divide the numbers without a remainder. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, and the factors of 18 are 1, 2, 3, 6, 9, and 18.
Common factors are factors that the two numbers share. In our example, the common factors of 12 and 18 are 1, 2, 3, and 6.
The greatest common factor (GCF) is the largest of these common factors. This helps in multiplication and division of numbers, particularly when simplifying fractions. Here, the GCF of 12 and 18 is 6.
To find the GCF more quickly, you can use the factor-label method. Divide both numbers by a common factor and continue this process with the resulting numbers until you can't find any common factors other than 1. The GCF is the product of all the common factors you used to divide.

p: 1 is the multiplicative identity
q: a · 0 = a
Which of the following statements is true?
p \/ q
p /\ q
p --> q
We are given
p: 1 is the multiplicative identity
Firstly, we will verify whether it is true
Multiplicative identity:
[tex]A \cdot 1=A[/tex]
Here , 1 is the multiplicative identity
So, 1 is multiplicative identity
so, statement p is true
q: a · 0 = a
we know that whenever we multiply any expression by 0
It will result in 0
so, this statement is false
now, we will verify each options
option-A:
p \/ q
so, we can plug
T \/ F = T
so, this is TRUE
option-B:
p /\ q
so, we can plug
T /\ F = F
so, this is FALSE
option-C:
p --> q
we can plug
T-->F = F
so, this is FALSE
The statements p \/ q (p OR q) is true since the proposition p is true and hence the whole OR operation is true, p /\ q (p AND q) and p --> q (p implies q) are false since the proposition q is false.
Explanation:The given propositions are "p: 1 is the multiplicative identity" and q: a · 0 = a. Let's analyze each proposed relation among them:
p \/ q (p OR q): This is false. While p is true (since any number multiplied by 1 gives the same number), q is false (any number multiplied by 0 gives 0, not a). However, in an OR operation, if one statement is true, the whole statement is true. Hence, p \/ q is truep /\ q (p AND q): This is false. While p is true, q is false as explained earlier. In an AND operation both statements must be true for the whole statement to be true. Hence, p /\ q is falsep --> q (p implies q): This is false. In implication, if p is true, then q must be true.

Given: ΔWXY is isosceles with legs WX and WY; ΔWVZ is isosceles with legs WV and WZ. Prove: ΔWXY ~ ΔWVZ
Triangles ΔWXY and ΔWVZ are similar because they are both isosceles with two pairs of congruent angles and a shared vertex angle, which satisfies the AA similarity criterion.
Explanation:To prove that triangles ΔWXY and ΔWVZ are similar, we need to establish that they have the same angle measures and their sides are proportional. Since we know ΔWXY and ΔWVZ are both isosceles triangles, they have two angles of equal measure. Specifically, the base angles of an isosceles triangle are congruent, therefore in ΔWXY, angles WYX and WXV are equal, and in ΔWVZ, angles WZV and WVZ are equal.
We also know that these triangles share the vertex angle at W, which means ΔWXY and ΔWVZ both have the angle W in common. This establishes that all corresponding angles between ΔWXY and ΔWVZ are congruent. Since both triangles are isosceles and have two pairs of congruent angles (base angles) and a common vertex angle, they are similar by the AA (Angle-Angle) similarity criterion. The ratio of the sides opposite the equal angles in isosceles triangles should be constant, thereby confirming the similarity.

Ryo accidentally ordered 240% percent as many eggs as his restaurant needs. What fraction of the number of eggs his restaurant needs did Ryo order?
Answer:
Ryo ordered [tex]\frac{12}{5}[/tex] of the number of eggs his restaurant needs.
Step-by-step explanation:
Suppose, the number of eggs his restaurant needs is [tex]x[/tex]
Ryo ordered 240% as many eggs as his restaurant needs. So, the number of eggs he ordered [tex]= x\times 240\% = x\times \frac{240}{100}= 2.4x[/tex]
For finding the fraction of the number of eggs his restaurant needs, we just need to divide "number of eggs ordered" by the "number of eggs needed".
So, the fraction will be: [tex]\frac{2.4x}{x}= 2.4 = \frac{24}{10}= \frac{12}{5}[/tex]
That means, Ryo ordered [tex]\frac{12}{5}[/tex] of the number of eggs his restaurant needs.
Ryo ordered 12/5 of the number of eggs his restaurant needs.
Given that Ryo accidentally ordered 240% percent as many eggs as his restaurant needs, to determine what fraction of the number of eggs his restaurant needs did Ryo order, the following calculation must be performed:
240/100 = X 10/24 = X 12/5 = X
Therefore, Ryo ordered 12/5 of the number of eggs his restaurant needs.
