Answer:
B. (x, y) → (−x, y), (x, y) → (x + 1, y + 1)
Step-by-step explanation:
Explanation:-
Type of Transformation Change to co-ordinate point
Vertical Translation up 'd' units ( x, y) → (x , y +d)
Vertical Translation down 'd' units ( x, y) → (x , y -d)
Horizontal translation left 'c' units ( x, y) → (x-c , y )
Horizontal translation right 'c' units ( x, y) → (x +c , y )
Reflection over x -axis ( x, y) → (x , -y )
Reflection over y -axis ( x, y) → (-x , y )
Given data
A triangle has vertices at B(−3, 0), C(2, −1), D(−1, 2).
a) see above transformation table
i) First Reflection over y- axis
(x, y) → (−x, y)
( -3 , 0) → (3, 0)
Next Horizontal translation right '1' units and Vertical Translation up '1' units
(x ,y) → (x +1 , y+1)
(3 +1 , 0+1)
(4 ,1)
∴ (-3 ,0) →(4,1)
b)
i) First Reflection over y- axis
(x, y) → (−x, y)
( 2 , -1) → (-2, -1)
Next Horizontal translation right '1' units and Vertical Translation up '1' units
(x ,y) → (x +1 , y+1)
(-2 +1 , -1+1)
(-1 ,0)
∴ ( 2 , -1) → (-1, 0)
c)
i) First Reflection over y- axis
(x, y) → (−x, y)
( -1 , 2) → (1, 2)
next Horizontal translation right '1' units and Vertical Translation up '1' units
(x ,y) → (x +1 , y+1)
(1, 2) → (1 +1 , 2+1)
→ (2 ,3)
∴ ( -1,2) → (2 ,3)
B(−3, 0), C(2, −1), D(−1, 2) is transformation would produce an image with vertices B″(4, 1), C″(−1, 0), D″(2, 3)

A password needs to be set up. Which method would have the highest number of
outcomes possible?
Answer:
the permutation of the alphabet or mixed (digits and letters)
Step-by-step explanation:
We are asked which method gives the greatest number of possible results when you want to configure a password, in this case our option is through combinations or permutations.
In a password the order matters, therefore it would be by the permutations method.
When creating a password it can be created with digits or letters, in general terms, digits are in less quantity than letters, therefore the greatest possible number would be through the permutation of the alphabet.
Although if you can do a mixed password, the result could have a higher number of outcomes

Answer:
The length of the radius is 3cm.
Step-by-step explanation:
Given that a circle is inscribed in a square. The side of the circle touches the side of the square which is the diameter. So the diameter of circle is 6cm, in order to find it's radius, you have to duvide it by 2 :
[tex]radius = diameter \div 2[/tex]
[tex]radius = 6 \div 2[/tex]
[tex]radius = 3cm[/tex]

hi can anybody help me with this i will mark them as brainliest
Answer:
5.75 cm²
Step-by-step explanation:
→ Utilise the area of a triangle formula
Area of a triangle = 0.5 × Base × Height
→ Identify base and height in the triangle
Base = 4.6 cm
Height = 2.5 cm
→ Substitute in the values into the area of a triangle formula
Area of a triangle = 0.5 × 4.6 × 2.5
→ Simplify
Area of a triangle = 5.75 cm²
Area of a triangle = 1/2 x base x height
= 1/2 x 4.6 x 2.5
= 5.75 sq. cm
Two jokers are added to a 52 card deck and the entire stack of 54 cards is shuffled randomly. What is the expected number of cards that will be strictly between the two jokers?
Answer: 52/3
Step-by-step explanation:
Each card has an equal likelihood of being either on top of the jokers, in between them,
or below the jokers. Thus, on average, 1/3 of them will land between the two jokers.
Answer:
52/3
Step-by-step explanation:
The probability that they will be landed on is 52/3

Find the difference: sqrt20-sqrt80
Answer:
-2sqrt5
Step-by-step explanation:
Lets begin by simplifying the radicals.
20 can be factored into 4*5, and since 4 is a perfect square, we can take out a 2.
therefore:
sqrt20 = 2sqrt5
80 can be factored into 16*5, and since 16 is a perfect square, we can take out a 4
therefore:
sqrt80 = 4sqrt5
So finally we have, 2sqrt5-4sqrt5 = -2sqrt5
The solution for the difference of √20 - √80 is,
⇒ - 2√5
We have to given that,
An expression is,
⇒ √20 - √80
We can simplify it as,
⇒ √20 = √5 × 4
= 2√5
⇒ √80 = √16 × 5
= 4√5
So, We can write as,
⇒ √20 - √80
⇒ 2√5 - 4√5
⇒ √5 (2 - 4)
⇒ - 2√5
Therefore, The required solution is,
⇒ - 2√5

The average wage for an electrician in CA is $25.47/hour. That is 11% above the national average. What is the national average?
Answer:
$22.95/hour.
Step-by-step explanation:
It is given that the average wage for an electrician in CA is $25.47/hour. That is 11% above the national average.
Let as consider x be the national average.
11% above the national average is
[tex]x+\dfrac{11}{100}x=x+0.11x=1.11x[/tex]
The average wage for an electrician in CA is 11% above the national average. So,
[tex]1.11x=25.47[/tex]
Divide both sides by 1.11.
[tex]x=\dfrac{25.47}{1.11}[/tex]
[tex]x=22.945945...[/tex]
[tex]x=22.95[/tex]
Therefore, the national average is $22.95/hour.

Another line “r” is perpendicular to the line 3y = 6x + 9. Find the gradient of the line "r" show your working
Answer:
Line r has a gradient of -1/2
Step-by-step explanation:
Perpendicular lines have a gradient of negative reciprocal to each other such that multiplying both the slopes give -1
=> Gradient of this line = 2
=> Gradient of line perpendicular to it = [tex]\frac{-1}{2}[/tex]
Multiplying both gradients:
=> 2 * [tex]\frac{-1}{2}[/tex]
=> -1

how to solve 4(7-3x)=7(4-2x)
Answer:
Step-by-step explanation:
First, you distribute the 4 and 7 to the stuff inside the parentheses 28 - 12x = 28 - 14x then add 28 to both sides -12x = -14x then add 14x to both sides 2x = 0 then divide both sides by 2 x = 0
Answer:
x=0
Step-by-step explanation:
4(7-3x)=7(4-2x)
Distribute
28 -12x = 28 -14x
Subtract 28 from each side
-12x = -14x
Add 14x to each side
-12x+14x = -14x+14x
2x=0
x =0
For the real-valued functions, find the composition and specify its domain using interval notation.
Answer:
Composition: [tex]f(x)\,^o\,h(x)=4\,\sqrt{x+4} -1[/tex]
Domain = { [tex]x\,/\,x\geq \,-4[/tex] }
Step-by-step explanation:
Given
[tex]f(x)=4\,x-1\,\,\, and \,\,\, h(x)=\sqrt{x+4}[/tex]
The requested composition becomes:
[tex]f(x)\,^o\,h(x)=f(h(x))\\f(x)\,^o\,h(x)=f(\sqrt{x+4} )\\f(x)\,^o\,h(x)=4\,\sqrt{x+4} -1[/tex]
Then the Domain consists of all Real x-values for which the function is defined. In this case, the function is defined for all x-values for which the square root is defined, that is all x values for which:
[tex]x+4\geq \,0[/tex] (so the square root is defined in the Real number system)
This means [tex]x\geq \,-4[/tex]
The Domain is then all the Real x-values such that [tex]x\geq \,-4[/tex]
