The correct answer from each drop-down menu is as follows:
The function p is a quadratic function.When the length of the tomato patch is 8 feet, the area of the bell pepper patch is equal to 16 square feet.The maximum possible area of the bell pepper patch is 18 square feet when the length of the tomato patch is 6 feet.What is a quadratic function?A quadratic function can be defined as a mathematical expression that can be used to define and represent the relationship that exists between two or more variable on a graph.
In Mathematics, the graph of any quadratic function is parabolic because it is a u-shaped curve. For the given quadratic function, the graph is a downward parabola because the coefficient of x² is negative.
Therefore, function p is a quadratic function.
When the length of the tomato patch is 8 feet, the area of the bell pepper patch is given by:
p(x) = -0.5x² + 6x
p(8) = -0.5(8)² + 6(8)
p(8) = -0.5(64) + 48
p(8) = -32 + 48
p(8) = 16 square feet.
From the graph, we can logically deduce that the maximum possible area occurred at x = 6 feet. Thus, maximum possible area is given by:
p(x) = -0.5x² + 6x
p(6) = -0.5(6)² + 6(6)
p(6) = -18 + 36
p(6) = 18 square feet.

The diagram below shows a large cone divided horizontally into two parts A and B. Given that the vertical height of A and B are equal, and that the volume of A is x cm³. Express the volume of the entire large cone in terms of x. [2] If the volume of part B is 3500 cm³, calculate the volume of cone A. [2]
Answer:
3500cm3
Step-by-step explanation: since A and B are equal, and B has a volume of 3500 cm3 then A will have the same.
Extra: The horizontal measure of A is 1500 and the verticle is 1500
Position and label each triangle on the coordinate plane.
right ΔM N O with right angle at point M and legs of lengths a and 2 a .
We need to position the right triangle Δ MNO in the first quadrant with coordinates , M(0,0) , N (0,a) & O (2a,0).
It is given that Δ MNO with right angle at point M has legs of lengths a and 2a .
We have to position the triangle on coordinate plane.
What is a right angled triangle ?
A right-angled triangle is a type of triangle that has one of its angles equal to 90 degrees.
As per the question ;
The triangle is a right angle triangle, so it's two sides can be located
on axis.
Place the right angle of the triangle Δ MNO at M.
i.e., M will have coordinates (0,0)
The origin will allow the two legs to be along the x and y-axes , so position the triangle in the first quadrant.
As N is on the y-axis ;
Its x-coordinate will be 0 and the y-coordinate will be a , because the leg is a units long.
i.e., N will have coordinates (0,a)
As O is on the x-axis,
its y-coordinate will be 0 and the x-coordinate will be 2a , because the leg is 2a units long.
i.e.,
O will have coordinate (2a,0)
We can put these coordinates after placing the triangle in the first quadrant i.e., M (0,0) , N (0,a) & O (2a,0).
Thus , we need to position the right triangle Δ MNO in the first quadrant with coordinates , M(0,0) , N (0,a) & O (2a,0).

Find the missing term(s) of each arithmetic sequence. -1, □, 11,. . . .
The missing term is 6.
Here the sequence is -1,__, 11...
An arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
Here the sequence is in an arithmetic sequence, as there is a common difference between the two numbers.
To find the nth term of the sequence we have a formula:
[tex]a_{n}[/tex] = a + (n-1)d
From this we can find a common difference, as we know the 3rd term of the sequence.
[tex]a_{3}[/tex] = -1 + (3-1) d
11 = -1 + 2d
2d = 12
d = 6
Now we have to the 2nd term of the series we have

Given the question, <11 and <14 are supplementary because they sum up to give 180 degrees. Detail below
What are supplementary angles?These are angles that sum up to give 180 degrees. On the other hand, angles on a straight line sum up to give 180 degrees.
Considering the question given above, we can prove that <11 and <14 are supplementary as follow:
<11 + <12 = 180 (angle on straight line)
But
<12 = <14 (corresponding angles)
Thus,
<11 + <14 = 180
Recall
Angle that sum up to give 180 are called supplementary angles
Therefore,
<11 + <14 = 180 => supplementary

What are the solutions of the rational equation?
a. x-1 / x+2 = x² + 2 x-3/x+2
The solutions of the rational equation x-1 / x+2 = x² + 2 x-3/x+2 are x = -2 and x = 1
In this question,
We have been given a rational equation.
x-1 / x+2 = x² + 2 x-3/x+2
We need to find the solution of given rational equation.
Here, the denominator is same on the both sides.
x-1 / x+2 = x² + 2 x-3/x+2
⇒ x - 1 = x² + 2 x-3
⇒ x² + 2x - 3 - x + 1 = 0
⇒ x² + x -2 = 0
We solve above quadratic equation.
⇒ x² + 2x - x - 2 = 0
⇒ x(x + 2) - (x + 2) = 0
⇒ (x + 2)(x - 1) = 0
⇒ x + 2 = 0 or x - 1 = 0
⇒ x = -2 or x = 1
Therefore, the solutions of the rational equation x-1 / x+2 = x² + 2 x-3/x+2 are x = -2 and x = 1

Identify the vertex, the axis of symmetry, the maximum or minimum value, and the domain and the range of each function.
y=(x-125)²+125 .
Each function's vertex, axis of symmetry, maximum or lowest value, domain, and range are all described as follows: Vertex: (125,125); range: (125,125); minimum: at y=125; x=125; maximum: no., axis of symmetry is x=125.
Describe Domain and Range.The domain of a function is the set of values that we are allowed to enter into our function.
The set of values that a function can accept as input is known as its range.
According to given data;y=(x-125)²-125
we know that;
y=(x-h)²+k
Vertex: In this form, the vertex (or, in other words, the "pointy bit") is given to us in the (h ,k);here we have (125,125).
Axis of symmetry : Two equal segments of the parabola. It moves straight up and down via the vertex.
Thus, we may formulate an equation for the vertical line that passes through the vertex. It is x=125 in this query..
Maximum and lowest values: Here, we're concerned in examining the vertex to determine whether it is at the maximum or lowest of the parabola's range (i.e., when a negative sign is placed in front of the (x-h) = 0 term, respectively).
Range: The value of range is (125,∞ )

How long will it take to catch up with the robber?Let 30minutes = 0.5 hours.
Let x represent the time for which the marshal has ran.
On this note, the robber must have galloped at; (x +0.5) hours.
Hence, it follows from the task content that if they are at the same distance from the bank; we have;
