Answer:
a) vertical expansion by a factor of 2; translation 3 units left and 5 units down
b) see attached
Step-by-step explanation:
a.Describing transformations is all about matching patterns. The elements of the transformed function are matched with the elements of a transformation.
Vertical scalingA function is scaled vertically by multiplying each function value by some scale factor. In generic terms, the function f(x) is scaled vertically by the factor 'c' in this way:
original function: f(x)scaled by a factor of 'c': c·f(x)If we want the function f(x) = x² scaled vertically by a factor of 2, then we have
f(x) = x² . . . . . . . original function
2·f(x) = 2x² . . . . scaled vertically by a factor of 2
On a graph, each point is vertically twice as far vertically from some reference point (the vertex, for example) as it is in the original function graph.
Horizontal translationA function is translated to the right by 'h' units when x is replaced by (x -h).
original function: f(x)translated h units right: f(x -h)If we want the function f(x) = x² translated right by 3 units, we will have ...
f(x) = x² . . . . . . . . . . . original function
f(x -3) = (x -3)² . . . . . .translated right 3 units
Note that translation left by 3 units would give ...
f(x -(-3)) = f(x +3) = (x +3)² . . . . translated left 3 units
On a graph, each point of the left-translated function is 3 units left of where it was on the original function graph.
Vertical translationA function is translated upward by 'k' units when k is added to the function value.
original function: f(x)translated k units up: f(x) +kThe value of k will be negative for a translation downward.
If we want the function f(x) = x² translated down by 5 units, we will have ...
f(x) = x² . . . . . . . . . . . original function
f(x) = x² -5 . . . . . . . . .translated down 5 units
Combined transformationsUsing all of these transformations at once, we have ...
f(x) = x² . . . . . . . . . . . . . . . . . original function
c·f(x -h) +k = c·(x -h)² +k . . . scaled by 'c', translated h right and k up
Compare this to the given function:
y = 2(x +3)² -5
and we can see that ...
c = 2 . . . . . . vertical scaling by a factor of 2h = -3 . . . . . translation 3 units leftk = -5 . . . . . translation 5 units downThis is the pattern matching that is described at the beginning.
__
b.When graphing a transformed function, it is often useful to start with a distinctive feature and work from there. The vertex of a parabola is one such distinctive feature.
TranslationThe transformations move the vertex 3 units left and 5 units down from its original position at (0, 0). The location of the vertex on the transformed function graph will be at (x, y) = (-3, -5).
Vertical scalingThe graph of the parent function parabola (y= x²) goes up from the vertex by the square of the number of units right or left. That is, 1 unit right or left of the vertex, the graph is 1 unit above the vertex. 2 units right or left, the graph is 2² = 4 units above the vertex.
The scaled graph will have these vertical distances multiplied by 2:
±1 unit horizontally ⇒ 2·1² = 2 units vertically; points (-4, -3), (-2, -3)±2 units horizontally ⇒ 2·2² = 8 units vertically; points (-5, 3), (-1, 3)The graph of the transformed function is shown in blue in the attachment.
__
Additional comment
The vertical scale factor 'c' may have any non-zero value, positive or negative, greater than 1 or less than 1. When the magnitude is less than 1, the scaling is a compression, rather than an expansion. When the sign is negative, the graph is also reflected across the x-axis, before everything else.

What kind of function is an exponential function?
Answers
An exponential function is a function in which the variable (usually represented by "x") is the exponent, rather than the base.
The most common form of an exponential function is f(x) = b^x, where b is a positive constant known as the base of the function.
Exponential functions can take many different forms, but they all have one thing in common: the variable is in the exponent. In most cases, the base of the function is a positive constant, and the exponent is the input variable. Exponential functions can also be used to model a wide variety of real-world phenomena, such as population growth, compound interest, and decay of radioactive materials.
The graph of an exponential function is always a smooth curve that increases or decreases at an increasing rate. The slope of the curve increases as x increases, which means that the rate of change of the function also increases as x increases.

Why is a line of longitude called a meridian Class 6?
Answers
A line of longitude is called a meridian because it connects the North and South poles and forms a circle around the Earth, like the sun's meridian path during the day.
A line of longitude is an imaginary line that circles the Earth and runs in a north-south direction. It is measured in degrees and divides the Earth into two equal halves, the Eastern Hemisphere and the Western Hemisphere. This line is called a meridian because it is derived from the Latin word meridies which means mid-day or noon. The sun's path across the sky during the day follows a meridian from the North Pole to the South Pole, and this is what inspired the term "meridian" to describe the line of longitude.

What is inequality?A linear inequality is one that would result in a linear equation if we were to substitute the equals relation for the inequality. When solving the inequality, the direction of an inequality is reversed when we multiply or divide both sides by a negative value.The collection of all solutions makes up the solution set for an inequality.
Here,
Now, in order to determine which ordered pairs are a solution, we need to substitute the coordinate points into the left side of the inequality and check against right side for the validity.
A. (0,0)
5(0) - 3(0) = 0 ≤ 7
So, (0,0) is a solution.
B. (3, 5)
5(5) - 3(3)= 25 - 9 = 16 ≥ 7
So, (3, 5) is not a solution.
C. (1,2.5)
5(2.5) - 3(1)= 12.5 - 3 = 9.5 ≥ 7
So, (1,2.5) is not a solution.

What is midpoint formula Class 9?
Answers
In class 9, the midpoint formula is a mathematical formula used to find the midpoint of a line segment given the coordinates of its two endpoints. The midpoint formula is:
(x, y) = ( (x1 + x2) / 2, (y1 + y2) / 2)
Where (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the line segment, and (x, y) are the coordinates of the midpoint.
For example, if the coordinates of the two endpoints of a line segment are (3, 4) and (7, 10), you can use the midpoint formula to find the coordinates of the midpoint:
(x, y) = ( (3 + 7) / 2, (4 + 10) / 2)
(x, y) = (5, 7)
So the midpoint of the line segment with endpoints (3, 4) and (7, 10) is (5, 7)
The midpoint formula is used in class 9 to find the midpoint of a line segment in coordinate geometry. It's a simple way to find the point which is exactly in the middle of two given points. It can be used to find the center of a circle if we know the coordinates of two points on the circumference.

A cubical box of cardboard has an edge 4.8 m long. how many closed cuboidal boxes of dimension 24 cm×12cm×10cm can be made out of it
Answers
Answer
38,400
Step by Step Explanation
Firstly we have to get the volume of the cube box in cm³ which is 480³ = 110,592,000
Secondly we have to get the volume of the cuboid in cm³ too which is 24×12×10 = 2,880
And lastly, 110,592,000/2,880 = 38,400
The number of closed cuboidal boxes is 38400.
Side of the Cubical Box, a = 4.8 m
Using the formula,
Volume of a cube: V = a³
V1 = a³
V1 = (4.8)³
V1 = 110.59 m³
Dimension of Cuboidal Boxes,
Length, l = 24 cm
Breadth, b = 12 cm
Height, h = 10 cm
Using the formula,
Volume of cuboid : V = l × b × h
V2 = l × b × h
V2 = 24 × 12 × 10
V2 = 2880 cm³ or 0.0028m³
Number of closed cuboidal boxes,
[tex]=\frac{Volume of cube}{Volume of cuboid}[/tex]

A line on a line graph that has a positive slope rises as the line advances from left to right.Positive slopes are founded on the idea that when x rises, y rises as well, making the ratio of y/x positive. Negative slopes are founded on the idea that when x rises, y falls. This results in a negative change in y and a positive change in x, which yields a negative result.The slope of the line will be,In 10 months the savings will be at,The graph of this line will positive slop.

The angle formed by the ladder with the ground is 90 degrees. The angle formed by the slide with the ground is x. What is the measure of the angle that the slide makes with the ground, x, to the nearest degree?.
Answers
The angle made by the slide of length 14.5 ft with the ground is 36°
The length of the slide = 14.5ft
The length of the ladder = 8.5 ft
The angle made by the ladder and ground = 90°
The angle formed by the slide can be found using the Pythagoras theorm,
sinθ = O / H
where θ is the angle made by the slide
O is the side opposite to the angle of the slide
H is the side that is hypotenuse with the slide
Let us rearrange the above equation in order to get the angle of the slide,
θ = sin⁻¹ (O/H)
Let us substitute the known values in the above equation, we get
θ = sin⁻¹ (8.5 / 14.5)

If another right triangle contains a 30° or a 60° angle but is a different size, what can you say about the side lengths of that triangle in terms of the given triangle? Explain your answer.
Answers
The side lengths of the new right triangle can be determined by the ratio of the given triangle.
What is triangle?A triangle is a three-sided polygon with three straight sides that are connected at three corners. It is one of the most basic shapes in geometry and is found in many areas of mathematics. Triangles can be classified according to their angles, sides, and size. They can be equilateral, isosceles, or scalene, depending on the size of their angles and sides. Triangles are used in a variety of fields, including architecture, engineering, construction, art, and design.
The side opposite the 30° angle will always be half the length of the hypotenuse, while the side opposite the 60° angle will always be equal to the square root of three times the length of the side opposite the 30° angle. This means that if the hypotenuse of the given triangle is 2, then the side opposite the 30° angle will be 1 and the side opposite the 60° angle will be √3.
Therefore, for any other right triangle containing a 30° or a 60° angle, the side length can be found by multiplying the side length of the given triangle by the same ratio. For example, if the hypotenuse of the new triangle is 6, then the side opposite the 30° angle will be 3 and the side opposite the 60° angle will be 3√3.
In conclusion, for any right triangle containing a 30° or a 60° angle, the side lengths can be determined by multiplying the side lengths of the given triangle by the same ratio.

According to the Polygon Interior Angles Sum Theorem, the sum of the interior angle measures of an n-sided convex polygon is (n−2)·180°. Write an equation setting this expression equal to the given angle measure. Then solve for n.
Answers
The equation will be represented as angle = (n - 2) × 180.
The value of n is 2.
How to calculate the equation?An equation simply has to do with the statement that illustrates the variables given. In this case, it is vital to note that two or more components are considered in order to be able to describe the scenario.
Since the sum of the interior angle measures of an n-sided convex polygon is (n−2)·180°.
An equation setting this expression equal to the given angle measure will be:
angle = (n - 2) × 180
Angle = 180n - 360
The value of n will be:
180n - 360 = 0
180n = 360
Divide
n = 360/180
n = 2.

f(x)=√x-4. Find the inverse of f(x) and its domain.
O A. f¹(x) = x² + 4; x≥0
OB. f¹(x) = (x+4)²; x≥-4
O c. f¹(x) = x² + 4; x ≥-4
O D. f¹(x) = (x+4)²; x≥0
Answers
The inverse of the function f(x) and its domain include the following: D. f⁻¹(x) = (x + 4)²; x ≥ 0.
What is an inverse function?In Mathematics, an inverse function simply refers to any type of function that is typically generated by reversing the mathematical operation in a given function (f(x)).
In order to determine the inverse of any function, you should swap both the input value (x-value) and output value (y-value) as follows;
f(x) = √x - 4
y = √x - 4
x = √y - 4
√y = x + 4
Taking the square of both sides of this inverse function, we have:
f⁻¹(x) = (x + 4)²
For the domain of this function, we have:
f(x) = √x - 4
When x= 0, we have:
f(0) = √0 - 4
f(0) = 0.
