Determine whether the dilation from A to B is an enlargement or a reduction. Then find the scale factor of the dilation.
Answers
From the figure we notice that the figure B is smaller than figure A, hence the dilation is a reduction.
Now, to find the dilation factor we notice that the right side of figure A has length 6; the same side for figure B has length 2; then we need to find a factor that fullfils:
[tex]6k=2[/tex]solving for k we have that:
[tex]\begin{gathered} 6k=2 \\ k=\frac{2}{6} \\ k=\frac{1}{3} \end{gathered}[/tex]Therefore the scale factor of the dilation is 1/3

Rational number will be 1/4, 2/3, √4 and Irrational number will be √8, √90, π/2, π as "Any whole number, fraction, or decimal that ends or repeats is a rational number. Any number that cannot be divided into a fraction and thus does not meet the definition of a rational number is considered to be irrational."
What is rational number?If p and q are integers and q is not equal to 0, then the number is in the form of p/q and is said to be rational. Among the rational number examples are 1/3, 2/4, 1/5, 9/3, and so forth. P/Q is the format for rational numbers, where p and q are open-ended integers and q 0. Thus, natural numbers, whole numbers, integers, fractions of integers, and decimals are all examples of rational numbers (terminating decimals and recurring decimals).
What is irrational number?Any real number that cannot be expressed as the quotient of two integers, p/q, where p and q are both integers, is referred to as an irrational number. For instance, the square root of 2 cannot be expressed as an integer or a fraction. A real number that cannot be expressed as a straightforward fraction is referred to as an irrational number. It cannot be described using a ratio. When p and q are integers and q is not equal to 0, N is not equal to p/q if N is irrational. Example: The numbers 2, 3, 5, 11, 21, and (Pi) are all illogical.
Here,
Rational number=1/4, 2/3, √4
Irrational number=√8, √90, π/2, π
As "Any whole number, fraction, or decimal that ends or repeats is a rational number. Any number that cannot be divided into a fraction and thus does not meet the definition of a rational number is considered to be irrational." so Rational number will be 1/4, 2/3, √4 and Irrational number will be √8, √90, π/2, π.

I have attached a picture of the graph below.
Please do not answer if you don't know or are not sure. Thank you.
Answers
Answer:
x = 8 for f(x) and x = 3 for h(x)
Step-by-step explanation:
the axis of symmetry is a vertical line which passes through the vertex of the graph with equation
x = c ( c is the value of the x- coordinate of the vertex )
the equation of a parabola in vertex form is
f(x) = a(x - h )² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = - 4(x - 8)² + 3 ← is in vertex form
with vertex (h, k ) = (8, 3 )
equation of axis of symmetry of f(x) is x = 8
given the graph of h(x) with vertex = (3, 2 ) , then
equation of axis of symmetry of h(x) is x = 3

You flip a coin and then spin this spinner. a) Determine whether these events are Independent or Dependent. Write I on D b) Find the probability that the coin lands tails-up and the spinner Yands on a I Write as a reduced fraction (numerator/denominator). 1
Answers
SOLUTION
Dependent events influence the probability of other events or their probability of occurring is affected by other events. Independent events do not affect one another and do not increase or decrease the probability of another event happening.
PART A
Since the flip of a coin would not affect the spin of the spinner, therefore these events are independent events.
The answer is 'I'
PART B
To find the probability that the coin lands tails-up and the spinner lands on 1, we would need to find the probability of getting a tail, then we find the probability of getting a 1
Therefore,
[tex]\text{Probaility}=\frac{no\text{ of favourable outcomes}}{\text{Total possible outcomes}}[/tex]When we flip a coin, the favourable outcome for a tail is 1 since a tail can only occur once in one flip. The total possible outcomes are 2, since we can have either a tail or head occurring in one flip.
Then,
[tex]Pr(\text{Tail)}=\frac{1}{2}[/tex]When we spin the spinner, the favourable outcome for one is 1, since we have only one slot for one on the spinner. The total possible outcome is 4 since we have 4 different number
slots on the spinner.
Then,
[tex]Pr(1)=\frac{1}{4}[/tex]To get the probability of getting a tail, then we find the probability of getting a 1 we multiply the probability of getting a one on the spinner and a tail on the flip.

The area of a rectangle is the product of its length and breadth. The maximum area enclosed by the fence is 36800 square meter and the dimensions of the enclosed area are 115 meter and 320 meter. The width is given as 115 meter.
What is a rectangle?A rectangle is a kind of parallelogram that has equal diagonals.
All the interior angles of a rectangle are equal to the right angle.
The diagonals of a rectangle do not bisect each other.
The dimensions of the given rectangle is (650 - 2x) and x.
Then, the area of the given rectangle is A(x) = x(650 - 2x)
In order to find the maximum area enclosed take the derivative of A(x) and equate it to zero as follows,
(660 - 2x) - 2x = 0
=> 4x = 660
=> x = 660 / 4
=> x = 115
Now, the maximum area is the value of A(x) at x = 115 as below,
= 115 × (650 - 2×115)
= 115 × 320
= 36800
The dimensions for the maximum area are 115 and (650 - 2 × 115) = 320.
Hence, the largest area enclosed is 36800 square meter and the dimensions of the enclosed area are 115 meter and 320 meter. The width is given as 115 meter.

Answers
According to the statement given in Part a, there is one table for 10 people and many tables for 4 and in total there are tables for 200 people. Taking x as the number of tables for 4 people, the inequality that represents this situation is:
[tex]\begin{gathered} 4x+10\leq200 \\ 4x\leq190 \\ x\leq47.5 \end{gathered}[/tex]It means that there must be less than or 47.5 tables in the cafeteria.
According to the statement given in Part b, there are 4 barrels that are the same size, and one that is 10 liters, in total they can hold 200 liters. Taking x as the volume hold by the 4 barrels , the inequality that represents this situation is:
[tex]\begin{gathered} 4x+10\leq200 \\ 4x\leq190 \\ x\leq47.5 \end{gathered}[/tex]It means that each barrel must hold less than or 47.5 liters of water.
These problems are similar because of the inequality used to find the solution is the same, they are different because of the variable that is found is completely different, the first one is the number of tables and the second one is the volume that can be hold by the barrels.

The graph shows the prices of the current year for the number of bushels.
And the table shows the prices of the previous year.
Part A: We will find the rate of change of bushels of corn in the current year.
As the graph shows a line, so, the rate of change will be the slope of the line
We will find the slope using two points.
As shown the line passes through the points (0,0) and (3,24)
So, the slope will be as follows:
[tex]slope=\frac{24-0}{3-0}=\frac{24}{3}=8[/tex]So, the rate of change = $8 per Bushel.
Part B: How many dollars more in the price of a bushel of corn in the current year than the previous year.
From the table: the price of the previous year = 21/3 = $7
And form the graph, the price of the current year = $8
So, the differnce = 8 - 7 = $1
So, the answer will be:
$1 more is the price of the current year than the price of the previous year.
