D. Translation
Answer:
C. Rotation
Step-by-step explanation:
Rotation is the movement of an object about a fixed point (center of rotation) either clockwise or in an anticlockwise direction. As seen from the image attached, the arrow represents that the object is rotated in an anticlockwise direction.
Translation transformation is the process of moving an object points in a particular direction at the same distance.
Dilation is the process of enlarging or reducing the size of an object.

3.8
4.
0.5
Answer:
The value of x is 1.
Step-by-step explanation:
You have to move all the x-terms to one side and the unrelated values to other side :
[tex]3.2x - 7.4 = - 7.8x + 3.6[/tex]
[tex]3.2x + 7.8x = 3.6 + 7.4[/tex]
Next, you have to add up :
[tex]11x = 11[/tex]
Lastly, you have to divide it by 11 :
[tex]x = 11 \div 11[/tex]
[tex]x = 1[/tex]
a person invest in 9000 in a bank. the bank pays 5% interest compounded semi annually. to the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 14800 dollars
Answer:
10.1 years.
Step-by-step explanation:
It is given that,
Principal = 9000
Rate of interest = 5%
No. of times interest compounded = 2 times in an year
Amount after certain time = 14800
The formula for amount:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
where, P is principal, r is rate of interest, n is no. of times interest compounded in an year and t is time in years.
Substitute the given values in the above formula.
[tex]14800=9000(1+\frac{0.05}{2})^{2t}[/tex]
[tex]\frac{14800}{9000}=(1+0.025)^{2t}[/tex]
[tex]1.644=(1.025)^{2t}[/tex]
Taking log both sides.
[tex]\log(1.644)=\log(1.025)^{2t}[/tex]
[tex]\log(1.644)=2t\log(1.025)[/tex] [tex][\because \log a^b=b\log a][/tex]
[tex]\frac{\log(1.644)}{2\log(1.025)}=t[/tex]
[tex]t=10.066[/tex]
[tex]t=10.1[/tex]
Therefore, the required time is 10.1 years.

The Dodgers (D) and the Angels (A) won a total of 165 games during a regular season, and the Angels won 19 games more than the Dodgers.
How many games did each team win?
btw this is solving systems of equations
Answer:
Dodgers won 73 games while angels won 73 + 19 = 92 games.
Step-by-step explanation:
The Dodgers and the angels won a total of 165 games during a regular season. The angels won 19 games more than the Dodgers .
The both team won a total of 165 games but we weren't given the game each team won but the game each team won can be gotten from the question.
Let
number of game won by Dodgers = x
number of game Angels won = x + 19
The both of them won 165 game altogether. This means the sum of their individual games won is equals to 165. Therefore,
x + x + 19 = 165
collect like terms
2x + 19 = 165
2x = 165 - 19
2x = 146
divide both sides by 2
x = 146/2
x = 73
Dodgers won 73 games while angels won 73 + 19 = 92 games.
Identify each x-value at which the slope of the tangent line to the function f(x) = 0.2x2 + 5x − 12 belongs to the interval (-1, 1).
Answer:
slope of the tangent
[tex]\frac{d y}{d x} = 0.2(2 x) + 5 (1)[/tex]
The slope of the tangent to the interval (-1 ,1)
m = 4.6 ,5, 5.4
Step-by-step explanation:
Step(i):-
Given function is f(x) = 0.2 x² + 5 x − 12
Slope of the tangent formula
[tex]m = \frac{d y}{d x}[/tex]
Let y = f(x) = 0.2 x² + 5 x − 12 ...(i)
Differentiating equation(i) with respective to 'x' , we get
[tex]\frac{d y}{d x} = 0.2(2 x) + 5 (1) -0[/tex]
let x=-1
[tex]m = \frac{dy}{dx} = 0.2 (2 X -1) +5 = 4.6[/tex]
let x=0
m = 5
let x=1
[tex]m = \frac{dy}{dx} = 0.2 (2 X 1) +5 = 5.4[/tex]
conclusion:-
slope of the tangent
[tex]\frac{d y}{d x} = 0.2(2 x) + 5 (1)[/tex]
The slope of the tangent to the interval (-1 ,1)
m = 4.6 , 5, 5.4
The x-values at which the slope of the tangent line to the function f(x) belongs to the interval (-1, 1) are x ∈ (-15, -10).
What is the function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
To find the x-values at which the slope of the tangent line to the function f(x) = 0.2x² + 5x − 12 belongs to the interval (-1, 1), we need to find the x-values at which the derivative of the function f(x) has a value within that interval.
The derivative of f(x) is given by f'(x) = 0.4x + 5. Therefore, we can find the x-values at which f'(x) belongs to the interval (-1, 1) by solving the inequality 0.4x + 5 ∈ (-1, 1).
To solve this inequality, we can rewrite it as follows:
-1 < 0.4x + 5 < 1
-1 - 5 < 0.4x < 1 - 5
-6 < 0.4x < -4
Dividing both sides of the inequality by 0.4, we get:
-15 < x < -10
Therefore, the x-values for which the slope of the tangent line to the function f(x) lies x ∈ (-15, -10).

The ideal mass for a piece of chocolate is 2.5 ounces. The actual mass for a production can vary by, at most, 0.08
ounces. Create an absolute value inequality and solve it to determine the range of chocolate masses.
Answer:
[tex]2.42\,oz \leq m_{real} \leq 2.58\,oz[/tex]
Step-by-step explanation:
The inequality must be the absolute value of the difference between real mass and ideal mass less or equal to 0.08 ounces. That is to say:
[tex]|m_{real} - m_{ideal}| \leq 0.08\,oz[/tex]
[tex]|m_{real} - 2.5\,oz| \leq 0.08\,oz[/tex]
There are two extreme cases:
[tex]m_{real,max} - 2.5\,oz = 0.08\,oz[/tex] and [tex]m_{real, min} - 2.5\,oz = -0.08\,oz[/tex]
[tex]m_{real, max} = 2.58\,oz[/tex] and [tex]m_{real,min} = 2.42\,oz[/tex]
Range of chocolate masses must be:
[tex]m_{real, min} \leq m_{real} \leq m_{real,max}[/tex]
[tex]2.42\,oz \leq m_{real} \leq 2.58\,oz[/tex]

Aby likes larger apple slices. She gets 6 slices from each apple. Complete the table that represents the proportional relationship.
Answer:
A=0 B=6 C=12
Step-by-step explanation:
If she gets 6 slices from each apple, then for A(which is 0 apples) you would get 0 slices. For B (which is 1 apple.) you would get 6 slices and for C (which is two apples) you would get 12 slices. I hope this helps!
Answer:
a=0
b=6
c=12
Step-by-step explanation:
4:24 is one of the ratios
lets use that as an example
divide both sides by 4 and you get
1:6
now lets use 3:18
divide both sides by 3 and you get
1:6
Now if you have 0 apples you have 0 slices
if you have one apple you get 6 slices...
because of the ratio 1:6 one apple=6 slices
now if you have 2 apples you have to times 1:6 by 2 which gives us 2:12 meaning you get 12 slices

The third side of the triangle measures more than 4 inches.
What are the properties of triangle for it's side?The sum of the length of the two sides of a triangle is greater than the length of the third side. The difference between the two sides of a triangle is less than the length of the third side.
According to the given question we have,
Length of the two sides of a triangle are 8 inches and 12 inches.
Let the length of the third side be x inches.
Now, according to the properties of a triangle
"The difference between the two sides of a triangle is less than the length of the third side".
Therefore,
12 - 8 < x
⇒ 4 < x
⇒ The third side of the triangle is greater than 4 inches.
Hence, the third side of the triangle measures more than 4 inches.

Point A is at (-7,-9) and point M is at (-0.5, -3).
Point M is the midpoint of point A and point B.
What are the coordinates of point B?
Answer:
(6,3)
Step-by-step explanation:
You can solve this by looking at the x and y coordinates independently.
The distance between -7 and -0.5 is 6.5.
The distance between -9 and -3 is 6.
Since point M is the midpoint, the distances between point A and point M should be the same, so you can literally just add the distances to the midpoint to find the other endpoint. This means that point B is located at (-0.5+6.5, -3+6) or (6, 3).
To check your work you can test the slope of the line and see that it is consistent from points A to B and from A to M.
[tex]\frac{(3--9)}{(6--7)}[/tex] = [tex]\frac{12}{13}[/tex] and [tex]\frac{(-3--9)}{(-.5--7)}[/tex] = [tex]\frac{6}{6.5}[/tex] which are both equal to ≈ .923077

B) 7
Step-by-step explanation:
Subtract 11 by both sides
3x - 4(x + 1) + 11 - 11 = 0 - 11
Simplify
3x - 4(x + 1) = -11
Distribute 4
3x - 4x - 4 = -11
Add 4 to both sides and combine like terms
-x - 4 + 4 = -11 + 4
-x = -7
Divide both sides by -1
x = 7
