The given curve is a second order, so it is a parabola. The area of the largest rectangle is 32 square units.
What is a curve?
A curve is a mathematical object that is similar to a line but does not have to be straight. A curve can be thought of intuitively as the trace left by a moving point.
Given curve is y = 12 - x².
The vertex of the parabola is on the y-axis. Thus y-axis is a symmetric line of the parabola.
Thus the x-coordinate of the vertices that are lying on the x-axis is the same but the opposite sign.
Thus the y-coordinate of the vertices that are lying on the x-axis is the same.
Thus the x-coordinate of the vertices that are lying on the curve is the same but the opposite sign.
Thus the y-coordinate of the vertices that are lying on the curve is the same.
The y - coordinate of the vertices that are lying on the curve is in form 12 - x².
Assume that the coordinate of the rectangle are A(a,0), B(-a,0), C(-a, 12 - a²), and D(a,12-a²).
The length of the rectangle is 2a.
The width of the rectangle is 12-a².
The area of the rectangle is A = 2a(12-a²).
A = 24a - 2a³
Differentiate with respect to a:
dA/da = 24 -6a² ....(i)
Equate dA/da with zero to find the critical point:
24 -6a² =0
6a² =24
a² = 4
a = ±2
Putting a=2 in A = 24a - 2a³:
A = 24×2 - 2×2³
A = 32

A regular hexagon is inscribed in a circle of radius 2 units. In square units, what is the area of the hexagon
The area of inscribed regular hexagon is 6[tex]\sqrt{3\\[/tex] unit square using the properties of equilateral triangles which combined, form the hexagon.
In a circle, a regular hexagon can be inscribed with all the six vertices of hexagon touching the circumference of the circle. The center of the circle is the center of the hexagon itself.
Now, if we join the center with all the vertices of the hexagon, we see six equilateral triangles are formed. The other two sides of each triangle apart from the ones joining the vertices of hexagon, are radii of the circle and all the sides are equal in length. The attached image can be referred for better understanding.
To find the area of the hexagon, we need to find the area of single equilateral triangle and multiply it by 6, as six triangles make a regular hexagon.
Radius of the circle ([tex]r[/tex]) = 2 units
Area of a single equilateral triangle = [tex]\sqrt{3} /4[/tex] [tex]r^{2}[/tex]
=( [tex]\sqrt{3} /4[/tex] ) × [tex]2^{2}[/tex]

1/12 OR 0.0083% PROBABILITY is that sit down in correct age order either clockwise.
What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin.
The coin is fair, thus the outcomes "heads" and "tails" are equally likely; the likelihood of "heads" is equal to the likelihood of "tails"; and because there are no other conceivable outcomes, the likelihood of either "heads" or "tails" is 1/2 (which is also an acceptable spelling).

Q3. There are 5 red sweets, 6 blue sweets and 9 yellow sweets in a bag.
Sarah takes a sweet at random.
She replaces it back and then
Take another sweet at random.
Work out the probability the both the sweets the same colour.
Answer:
Step-by-step explanation:There are a total of 20 sweets in the bag (5 red + 6 blue + 9 yellow).
To find the probability that Sarah takes two sweets of the same color, we need to find the probability of her choosing a sweet of a specific color on her first pick and then the probability of her choosing another sweet of that same color on her second pick.
For example, if she chooses a red sweet on her first pick, the probability of that happening is 5/20, or 1/4. Then the probability of her choosing another red sweet on her second pick, given that she already picked one, is 4/20, or 2/10. Therefore the probability of her choosing two red sweets in a row is (1/4) * (2/10) = 1/20.
Similarly, the probability of her choosing two blue sweets in a row is (6/20) * (5/20) = 3/50.
The probability of her choosing two yellow sweets in a row is (9/20) * (8/20) = 9/100.
The probability of her choosing two sweets of the same color is the sum of the probability of her choosing two red sweets, two blue sweets, or two yellow sweets in a row.
P(Two same color) = 1/20 + 3/50 + 9/100 = 11/50
So, the probability of her choosing two sweets of the same color is 11/50.

The length of the larger tabletop is 12 feet. What is its width, x?
The width of the tabletop is t feet when its length is 12 feet.
What is length and width?In contrast to width, which is used to describe how wide an object is, length simply states how long something is.
The term "width" is also used to refer to "breadth." It is the distance measured across a specific shape or object, such as a rectangle, whose lengths form right angles with the sides.
In contrast to the measurement of the area of the rectangle, which is a product of two units, the length and width. Length and width are two fundamental one-dimensional units. Today, a variety of length units are in use. The metre in SI units of measurement is the most fundamental of all.
Given that:
The length of a larger tabletop is 2 more than 2 times its width
l = 2(w) + 2
The length is 12
12 = 2(w) + 2
12 - 2 = 2w

Volume of the sphere to the nearest cubic cm will be 803.84 cm^3
A sphere has a spherical, symmetrical form. It is a three-dimensional solid with equal distances between each surface point and the center. On the basis of its radius, it has a surface area and a volume. There are no faces, corners, or edges on it.
The collection of all points in three-dimensional Euclidean space that are separated by a certain amount of space, or "radius," is known as a sphere (the "center"). The diameter is equal to twice the radius, and antipodes are pairs of locations on the sphere that are on opposing sides of a diameter.
Volume of sphere[tex]=\frac{4}{3} \pi r^3[/tex]
As we have the value of radius = r=4 cm
We have the value of total scoops = 3 mm

At a local play, student tickets cost $6 each and adult tickets cost $11 each. if ticket sales were $3,000 for 400 tickets, how many students attended the play?
As per the unitary method the number of students who attended the play is 280.
The unitary method is a mathematical method used to find the value of a single unit in a given set of values. In this case, we will be using it to find the number of student tickets sold at the local play.
Let's say that "x" represents the number of student tickets sold.
The cost of each student ticket is $6, so the total cost of student tickets is $6x. The total cost of adult tickets is $11y, where "y" represents the number of adult tickets sold. The total ticket sales for the play was $3,000, so we can write the equation:
$6x + $11y = $3,000
We already know the cost of student tickets and adult tickets, so we can substitute those values into the equation:
$6x + $11y = $3,000
$6x = $3,000 - $11y
Now we can divide both sides of the equation by $6 to find the value of x:
x = ($3,000 - $11y) / $6
Since the total ticket sales were $3,000 for 400 tickets, we can use that information to solve for y:
$3,000 = $6x + $11y
$3,000 = $6x + $11(400 - x)
Expanding the equation:
$3,000 = $6x + $4400 - $11x
Combining like terms:
$3,000 = $-5x + $4400
Adding $5x to both sides:
$3,000 + $5x = $4400
Subtracting $3,000 from both sides:
$5x = $4400 - $3,000
$5x = $1400
Dividing both sides by 5:
x = $1400 / $5
x = 280
So, 280 students attended the play.

A collection of six objects can be chosen from one of 120 possibilities. These six configurations comprise BDF, BFD, DBF, DFB, FBD, and FDB.
What is a permutation, exactly?A permutation is what? The number of possible arrangements for a given set is calculated mathematically, and this process is known as permutation. Simply said, a mutation is a term that refers to the variety of possible arrangements or orders. The arrangement's order is important when using permutations.
Out of the six things A, B, C, D, E, and F, rotations of items B, D, and F (a total of three items) must be listed.
Simply said, we must find every configuration for these three elements.
The three objects can be placed in three ways, which equals (3x2x1) ways, or six.
These six configurations are BDF, BFD, DBF, DFB, FBD, and FDB.

can someone help me with this? thanks
Answer:
a. y = 2x - 6
To find the slope of the equation, we need to find the coefficient of x which is 2. So the slope of this equation is m=2
To find the y-intercept, we can substitute x = 0 into the equation:
y = 2(0) - 6
y = -6
So the y-intercept of this equation is b = -6
b. y = 1/2 * x + 12
To find the slope of the equation, we need to find the coefficient of x which is 1/2. So the slope of this equation is m=1/2
To find the y-intercept, we can substitute x = 0 into the equation:
y = 1/2(0) + 12
y = 12
So the y-intercept of this equation is b = 12
Therefore, the slope-intercept form of the equation is y = 2x - 6 and y = 1/2x + 12 respectively.

Why is 1 U and 1 V graph a straight line?
A 1-U, 1-V graph is a special type of graph that has only one vertex of degree 1 (U) and one vertex of degree 2 (V). The edge connecting the two vertices is called the "bridge" of the graph.
Because the graph has only one vertex of degree 2, it forms a simple path (a straight line) between the two vertices. The vertex of degree 1 is a leaf, which means it is only connected to one vertex, and the vertex of degree 2 is the other end of the path. The path is a simple one, meaning it has no loops or multiple edges between the two vertices.
In a 1-U, 1-V graph, the vertex of degree 1 (U) can be thought of as the start of the path and the vertex of degree 2 (V) as the end of the path. Because there are no other edges or vertices in the graph, the path is the only structure in the graph and it's a straight line.
It's important to note that a 1-U, 1-V graph is a special case of a graph and it's not a general representation of all possible graphs. Most graphs have more than one vertex and multiple edges, making them more complex than a simple straight line.

WZ bisects RS at T. If RT = 15x + 5y, RS = 20x - 5y, WT = 40 and
ST=21, find the values of a and y.
The values of x and y are 1.8 units and 1.2 units respectively.
What is a perpendicular bisector?A perpendicular bisector is a line that bisects a line segment in two equal parts and makes an angle of 90° at the point of intersection. In other words, we can say that a perpendicular bisector divides a line segment at its midpoint making an angle of 90°.
Given that, RT = 15x + 5y, RS = 20x - 5y, WT = 40 and ST=21.
Here, RS=RT+ST
20x-5y=15x+5y+21
5x-10y=21 -------(I)
RT=ST
15x+5y=21 -------(II)
Multiply equation (II) by 2, we get
30x+10y=42 -------(III)
Add equation (I) and (III), we get
5x-10y+30x+10y=21+42
35x=63
x=63/35
x=9/5
x=1.8 units
Substitute x=1.8 in equation (I), we get
5(1.8)-10y=21
y=1.2 units
Therefore, the values of x and y are 1.8 units and 1.2 units respectively.

John was 5 years old when his pet dog, Spot, was born.
Use your equation to calculate how old John will be when Spot has his 4th birthday. Write only the final answer the number.
Step-by-step explanation:
S = age of Spot
J(S) = the age of John, when Spot is S years old.
J(S) = S + 5
J(0) when Spot was born = 0 + 5 = 5
J(4) when Spot has 4th birthday = 4 + 5 = 9
John will be 9 years old.
