Answers
Given the function f(x) = x
We will find the function g(x) whose graph is produced by the following transformations on the graph of f(x)
First, The graph of f is reflected vertically
So,
[tex]\begin{gathered} f(x)\rightarrow f(-x) \\ g(x)=-x \end{gathered}[/tex]Second, expanded horizontally by a factor of 2
So,
[tex]\begin{gathered} f(-x)\rightarrow f(-2x) \\ g(x)=-2x \end{gathered}[/tex]Finally, shifted right 6 units, and shifted down 4 units.
So,
[tex]\begin{gathered} f(-2x)\rightarrow f(-2(x-6))-4 \\ g(x)=-2(x-6)-4 \end{gathered}[/tex]Simplifying the function g(x):
[tex]g(x)=-2x+8[/tex]The graph of the function (f) and (g) will be as shown in the following figure:

Answers
Answer:
(A) (5,7) (7,4)
Explanation:
To determine the set of points that could be used to create a line with a slope of -3/2, we use the slope formula below.
[tex]\text{Slope}=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}}[/tex]Option A

A penny-farthing is a bicycle with a very large front wheel and a much smaller back wheel. Penny-farthings were popular in the 1800s and were available in different sizes. The ratio of the diameter of the front wheel of a penny-farthing to the diameter of the back wheel is 13:4. What is the ratio of the circumference of the front wheel to the circumference of the back wheel? Explain.
Answers
The Solution:
It is given in the question that the ratio of the diameter of the front wheel of a penny-farthing to the diameter of the back wheel is 13:4
[tex]\begin{gathered} \frac{D}{d}=\frac{13}{4} \\ \text{Where} \\ D=\text{diameter of the front wheel} \\ d=\text{diameter of the back wheel} \end{gathered}[/tex]We are required to find the ratio of the circumference of the front wheel to the circumference of the back wheel.
Step 1:
The formula for the circumference of a wheel (that is, a circle) is
[tex]\text{ circumference of a wheel = 2}\pi r=\pi d[/tex]Step 2:
We shall find the ratio of the circumference of the front wheel to the circumference of the back wheel.
[tex]\begin{gathered} \frac{\pi D}{\pi d}=\frac{13\pi}{4\pi}=\frac{13}{4} \\ \text{ So,} \\ 13\colon4 \end{gathered}[/tex]Therefore, the required ratio is 13:4

A bus travel's at an average speed of 65.1 miles in 3 hours in the city. how far could the bus travel in 8.2 hours?
Answers
177.94miles
Explanations:From the question, distance is directly proportional to the time taken. Mathematically;
[tex]\begin{gathered} d\alpha t \\ d=kt \\ k=\frac{d}{t} \end{gathered}[/tex]where:
d is the distance traveled
t is the time
If the bus travel's at an average speed of 65.1 miles in 3 hours in the city, the variation constant "k" is calculated as;
[tex]\begin{gathered} k=\frac{65.1\text{miles}}{3\text{hours}} \\ k=\frac{21.7mi}{hr} \end{gathered}[/tex]In order to determine how far could the bus travel in 8.2 hours
[tex]\begin{gathered} d=kt \\ d=\frac{21.7miles}{\cancel{hr}}\times8.2\cancel{\text{hrs}} \\ d=177.94\text{miles} \end{gathered}[/tex]Therefore the bus can travel for 177.94miles in 8.2hours

Which function is undefined for x = 0?O y=³√x-2Oy=√x-2O y=³√x+2Oy=√x+2
Answers
The above function is defined for (x=0)
From the question, we have
Function 1 - y = ∛x-2
Function 2 - y = √x-2
Function 3 - y = ∛x+2
Function 4 - y = √x+2
substituting (x = 0) to determine which function is undefined for (x = 0).
Function 1 - y = ∛x-2
substituting (x = 0), we get
y=∛-2
The above function is defined for (x=0).
Function 2 - y = √x-2
substituting (x = 0), we get
y = √-2
The above function is defined for (x=0).
Function 3 - y = ∛x+2
substituting (x = 0), we get
y = ∛2
The above function is defined for (x=0).
Function 4 - y = √x+2
substituting (x = 0), we get
y = √2
The above function is defined for (x=0).
Hence, it can be concluded that the above function is defined for (x=0)
Subtraction:
Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.
The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

Seth's father is thinking of buying his son a summer movie pass for $30 dollars. With the pass, matinees cost $2 each. Without thepass each movie is normally $6. If Seth plans to go to 30 movies this summer how much money would he save?
Answers
Theres a number of passes to purchase
Normal price (without pass) is $6
If Seth goes to all 30 movies without pass he will spend
30x6 = $180 dollars
WITH the pass Seth have $30 dollars , then dividing by 2 , this means he can go to 30/2 = 15 movies in summer with pass
Then remains another 15 movies that he can vo WITHOUT PASS
in this 15 movies Seth spends 15x6= $90 dollars
add this to the $30 spent in the other 15 movie
it gives 30+90 = $120 dollars
Finally substract
$180- $120= $60 dollars he can save

Area of square base of sides x is
[tex]Area=x^2[/tex]Volume = 4000cm^3
[tex]\begin{gathered} Volume=Bh \\ B=Base\text{ }Area \\ h=height \end{gathered}[/tex]Thus,
[tex]\begin{gathered} Volume=Bh \\ 4000=x^2h \\ \\ h=\frac{4000}{x^2} \end{gathered}[/tex]For the box to require the least possible material, is to simply minimize the surface area of the rectangular box
The surface Area is given as

Answers
Circle and Angles
Gerardo is skiing on a trail that has a radius of r = 0.9 km
He starts skiing at the 3-o'clock position. This means he is initially at the right of the center of the circular trail. This position corresponds to the zero degrees (or radians) reference.
The arc length of a circle of radius r is given by:
[tex]L=\theta r[/tex]Where θ is the central angle in radians.
We know Gerardo travels L=2.6 km in the counter-clockwise direction, thus the angle is calculated by solving for θ:
[tex]\theta=\frac{L}{r}\text{ }[/tex]Substituting:
[tex]\theta=\frac{2.6}{0.9}=2.8889rad\text{ }[/tex]Gerardo swept out 2.8889 radians.
Now we need to calculate the rectangular coordinates of the final position where Gerardo stopped skiing. Since the angle is less than one turn of the trail, and the angle is measured counter-clockwise, we can use the formulas:
x = r cos θ
y = r sin θ
Substituting:
x = 0.9 cos 2.8889 rad
x = -0.87 km
y = 0.9 sin 2.8889 rad
y = 0.23 km
Gerardo is -0.87 km to the right of the center. In fact, he is 0.87 km to the left of the center.
Gerardo is 0.23 km above the center of the ski trail.
