Answer:
B
Step-by-step explanation:
Looking at the graph, we can see that g(x) is a compressed version of f(x) in the x direction but stretched in the y direction. We know that it is compressed because the values of g(x) are inside of f(x) in the x direction, and that it is streched because the values of g(x) are higher than the values of f(x) in the y direction.
Next, we want to figure out how much g(x) is a compression/stretch of x.
In the y direction, at x=1, y=1. At x=3, y=9. The ratio between the y values is 9/1 = 9, so in the y direction, the graph is streched by 9.
A stretch in the y direction can be represented by kf(x), with k representing how much the graph is stretched. In our example, k=9, so we have
kf(x) = 9f(x) = 9(x²) = 9x². This is equal to (3x)² = 9x², or B
In the x direction, at x=1, y=1. At x=3, y=9. The ratio between the x values is 3/1 = 3, so in the x direction, the graph is compressed by 3.
f(kx) represents a compression by a factor of k in the x direction, and k =3 here, so we have
f(kx) = f(3x) = (3x)² = 9x² = B

|6a-5|=4a
the solutions are a= and a=
Answers
Answer:
a = 2.5, a = 0.5
Step-by-step explanation:
6a - 5 = 4a, and 6a - 5 = -4a
6a -5 = 4a
Subtract 6a from both sides
-5 = -2a
a = 2.5
6a - 5 = -4a
Subtract 6a from both sides
-5 = -10a
a = 0.5

Answer:
a=1/2 and a=5/2
Step-by-step explanation:
6a-5=4a:
Subtract 4a from both sides, ending up with 2a-5=0
Add 5 to both sides, ending up with 2a=5
Divide both sides by 2, ending up with a=5/2
6a-5=-4a
Add 4a to both sides ending up with 10a-5=0
Add 5 to both sides ending up with 10a=5
Divide both sides by 10 ending up with a=1/2

Suppose y varies directly as x, and y = 9 when x = 36. Find y when x= 100.
Answers
Answer:
25
Step-by-step explanation:
let x = 36
y = 9
x2 = 100
y2 = y2
y : x :: y2 : x2
We know,
Product of means = Product of extremes
That is,
y(x2) = x(y2)
Substituting the values,
9(100) = 36(y2)
=> 36(y2) = 900
=> y2 = 900/36
=> y2 = 25
so when x = 100, y =25

Find the number of ways of arranging N people in a straight line, if two particular people must always be separated.
Answers
Answer:
It’s the number of ways N people can be arranged in a straight line without restriction minus the number of arrangements in which the 2 people are together.
The number of ways N people can be arranged in a straight line without restriction = N!
The number of arrangements in which the 2 people are together = the number of possible positions for the left-hand person multiplied by the number of people who can be that person, multiplied by the number of possible arrangements for the other N - 2 people
= (N - 1) * 2 * (N - 2)!
= 2 (N - 1)!
So the number of ways N people can be arranged in a straight line if 2 particular people must be separated = N! - 2(N - 1)!

Answers
Step one:
given data
The marked price of a watch is Rs.2700
The value of the watch after adding VAT is Rs.2376
let us find the discount
= 2700-2376
=324
then the percentage discount is
=324/2700*100
=0.12*100
=12%

Tomás found the following prices when he was shopping for sports jerseys: $28, $36, $40, $30, and $28. What is the median price?
Answers
Answer:
$30
Step-by-step explanation:
To find the median, arrange numbers from smallest to largest
The # of data points in this scenario are 5, which is odd. If the # of data points is odd, the median is the data point in the center.
$28, $28, $30, $36, $40
if you wanted to find the median with an even # of data points, it's the average of the two middle data points.
The median price of the sport jerseys is : $30
Given the prices :
$28, $36, $40, $30, $28
To find the median price, we need to arrange the values in order :
Ordered prices = $28, $28, $30, $36, $40
The median formula = 1/2(n+1)th term
n = number of terms = 5
Hence,
Median price = 1/2(5 +1)th term
Median price = 1/2(6) = 3rd term
The 3rd term = $30.
Hence, the median price is $30

A) give a verbal description of the subset of real numbers represented by the inequality or the interval, B) sketch the subset on the rest of real number line, and C) state whether the interval is bounded or unbounded
Answers
An inequality is an expression which makes comparison between unequal expressions i.e. both sides of the inequality sign are not equal.
The verbal description of [tex]x > 5[/tex] is the set of all real numbers greater than 5 The interval is bounded (right bounded to be precise)The inequality is given as:
[tex]x > 5[/tex]
[tex]x > 5[/tex] means x greater than 5
So, the verbal description is as follows:
The set of all real numbers greater than 5
To sketch [tex]x > 5[/tex] on a number line, we consider the following:
> means greater than; so, the arrow on the number line must point to the right[tex]> 5[/tex] implies that the arrow must start on 5> also implies that the circle on 5 must be an open circleSee attachment for the sketch
To determine if the interval is bounded or not, we do the following.
[tex]x > 5[/tex] means that the x starts at a value greater than 5, and the value of x has no end.
This is represented as: [tex](5,\infty)[/tex]
Notice that 5 is at the right, while [tex]\infty[/tex] is at the left.
This means that the interval is bounded (right bounded to be precise)
