Which of the rules given below shows the transformation of f?
OA g(x) = f(x) - 4
O B. g(x) = fx-4)
OC.
g(x) = f(x + 4)
OD. g(x) = f(x) + 4
Answer:
A.) g (x) = f (x) - 2
Step-by-step explanation:
The first thing we are going to do in this case is to take into account the following definition.
Translations are transformations that change the position of the graph of a function.
The general shape of the graph of a function is moved up, down, to the right or to the left.
The translations are considered rigid transformations. Now we will see how these are performed.
Vertical translations:
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
To graph y = f (x) -k, move the graph of k units down.
Using the definition we conclude that:
g (x) = f (x) - 4
Two exponential functions, fand g, are shown in the figure, where g is a transformation of f, g (x) = f (x) - 4 equation shows transformation of f. The correct option is A.
What is exponential function?A mathematical function of the form [tex]f(x) = a^x[/tex], where an is a positive constant and x is the input variable, is an exponential function.
The characteristic curve of exponential functions rises or falls rapidly depending on whether an is greater or less than 1.
To determine the transformation of f which gives g, we need to examine how f has been transformed to obtain g.
Looking at the graph, we can see that g is a vertical shift of f. Specifically, g is obtained by shifting f downward by 2 units. Therefore, we need a rule that subtracts 2 from f (x) to get g (x).
Out of the given options, the only one that matches this description is:
g (x) = f (x) - 4
Option A subtracts 4 from f (x), which is not what we observe in the graph. Option B uses an incorrect format and is also subtracting 4 from f (x).
Option C adds 4 to x, which would result in a horizontal shift, not a vertical shift.
Therefore, the correct answer is A g (x) = f (x) - 2.

A circle is subdivided by a central angle of 90 degrees. The length of the subtended arc is 25 mm. What is the radius of the circle?
A:
[tex] \frac{50}{\pi} mm[/tex]
B:
[tex] \frac{\pi}{50} mm[/tex]
C:
[tex] \frac{25\pi}{2} mm[/tex]
D:
[tex]25mm[/tex]
Answer:
[tex](\text{A})\:\frac{50}{\pi}\:\text{mm}[/tex]
Step-by-step explanation:
This the arc is 90 degrees and there are 360 degrees in a circle, it makes up [tex]\frac{90}{360}=\frac{1}{4}[/tex] of the circle. Therefore, its length will be [tex]\frac{1}{4}[/tex] of the circumference. Since its length is 25 mm, the circumference is then [tex]25\cdot 4=100\:\text{mm}[/tex]. The circumference of a circle is given by [tex]2\pi r[/tex], where [tex]r[/tex] is the radius of the circle. Therefore, we can set up the following equation and solve for [tex]r[/tex]:
[tex]2\pi r=100[/tex]
Solving, we get:
[tex]2\pi r=100,\\\\r=\frac{100}{2\pi},\\\\r=\boxed{(\text{A})\:\frac{50}{\pi}\:\text{mm}}[/tex].

A community centre organises a raffle to raise money for charity
There is one prize to be won
Daniel buys 17 raffle tickets.
A total of 280 tickets were sold
What’s the probability that Daniel does not win the prize
Answer:
263 / 280
Step-by-step explanation:
Given that :
Number of tickets bought = required outcome = 17
Total number of raffle = total possible outcomes = 280
Probability = required outcome / Total possible outcomes
P(winning) = 17 / 280
P(not winning) = 1 - 17/ 280
= 263 / 280

what is 18 rounded to the nearst 1/4
Answer:
18
Step-by-step explanation:
1/4 is close to 0 so 18 rounded to the nearest ones place is just 18
Answer:
20
Step-by-step explanation:
When we round to the nearest ten, we will round up to a number that has a zero in the ones place but we have to look at the number in the ones place before we round to determine the number in the tens place. The rule is if the number in the place before the place we need to round (in this case the ones place would be what we look at to determine the rounded tens place) 1-4 is going to round down, keeping the tens place the same and the ones place goes to zero, and if the ones number place is 5-9 then we round up, bringing the ones to zero and the tens up by one tens place.

What is the MAD for the following data set? 5,15,10,35,25
elimination method
x-5=-y
3x-10=2y
Answer:
(4,1)
Step-by-step explanation:
Multiply the first equation by -3
(x-5=-y)*-3 = -3x+15=3y
Then combine like terms with the new equation and the second equation
(-3x+15=3y) + (3x-10=2y) = 5=5y
Divide 5 by both sides
1=y
Plug in 1 for y in an equation. Doesn’t matter which one and solve
x-5=-(1)
Distribute the negative sign to the 1
x-5=-1
Add 5 to both sides
x=4

To find:
The values of x.
Solution:
We have,
[tex](x-18)^2=1[/tex]
Taking square root on both sides, we get
[tex]x-18=\pm\sqrt{1}[/tex]
[tex]x-18=\pm 1[/tex]
Adding 18 on both sides, we get
[tex]x-18+18=\pm 1+18[/tex]
[tex]x=\pm 1+18[/tex]
Now,
[tex]x=1+18[/tex] and [tex]x=-1+18[/tex]
[tex]x=19[/tex] and [tex]x=17[/tex]
Therefore, the correct option is A.

Formula to calculate distance between two points:The distance d between two points [tex](x_{1},y_{1}),(x_{2},y_{2})[/tex] is,[tex]d=\sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-y_{1})^{2} }[/tex]
For given question,
Let [tex](x_{1},y_{1}) = (-7,8),(x_{2},y_{2})=(2,8)[/tex]
Let d be the distance between two points.
Using distance formula,
[tex]d=\sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-y_{1})^{2}[/tex]
[tex]d=\sqrt{(2-(-7))^{2}+ (8-8)^{2} }[/tex]
[tex]d=\sqrt{(2+7)^{2}+0^{2}[/tex]
[tex]d=\sqrt{9^{2}+0 }[/tex]
[tex]d=9[/tex] units

thank you for helping
Answer:
There are 40 books total
Step-by-step explanation:
you need to set a proportion
The first fraction is 55/100 it's over 100 because it's percent
the other fraction is 22/x the 22 is out of a total number so that's why it's on top and x because you don't know the total number of books
then you multiply diagonally
55×x= 22×100
55x=2,200
Then you solve it like a regular equation by dividing both sides by 55
x=40
