The point (-4,1) is totated 180 degrees counterclockwise using center (0,0). What are the coordinates of the image?
Answers
Answer:
Coordinates of the image are (4 , -1)
Explanation:
The rule for 180° rotation counterclockwise is:
(x , y) ⇒ (-x , -y)
This means that to get the coordinates of a point rotated 180° counterclockwise, all you have to do is flip the signs of both the x and the y
Now, we are given the point (-4 , 1)
Applying the above rule:
Hope this helps :)
Final answer:
A 180 degrees counterclockwise rotation around the origin (0,0) would flip a point (x,y) to its opposite (-x,-y). Therefore, if you rotate the point (-4,1) 180 degrees counterclockwise, the new coordinates of the point would be (4, -1).
Explanation:
In Mathematics, specifically in Geometry, when we conduct a 180 degrees counterclockwise rotation around the origin (0,0), every point on the plane rotates by 180 degrees in the counterclockwise direction.
For a point (x,y), a 180-degrees rotation would result in the point ending up at (-x,-y).
Therefore, if you rotate the point (-4,1) 180 degrees counterclockwise around the origin, the new coordinates of the point would be (4, -1).

Area of a circle is found using the formula: Area = π * r^2
Using 3.14 for π
Area of the bull'e eye = π * 2^2 = 4π = 4 * 3.14 = 12.56 square inches.
This is 20% of the entire target.
To find the area of the entire target, divide the area of the bull's eye by the percentage:
Area = 12.56 / 0.20 = 62.8 square inches.
Round the answer as needed.
Answer:
Area of target = 62.8 inch²
Step-by-step explanation:
A bull’s-eye with a 4-inch diameter covers 20 percent of a circular target.
Diameter of bull's eye = 4 inch
Given that bull’s-eye covers 20% of circular target.
Area of target = 62.8 inch²

first make the 10 of the 3/10 turn into a 100 so it will make the 100 of the 17/100.
to make 10 turn into a 100 you multiply it by 10. if you're going to multiply the bottom number by 10 then you have to do the same thing with the top number:
3/10 * 10/10
3*10=30
10*10=100
new equation:
30/100 + 17/100
now just add the top numbers and leave the 100's alone:
30/100 + 17/100
30+17=47
30/100 + 17/100 = 47/100
3/10 + 17/100
Find the LCD of the denominators, hence the name 'least common denominator'. To do that, list out the multiples of each denominator and find the least common one.
Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
Multiples of 100: 100
The least common denominator is 100.
Now, divide the denominator of 3/10 to get the new denominator of 100. Whatever you do to the bottom, you have to do to the top.
(3 × 10) / (10 × 10) + 17/100
30/100 + 17/100
Since the denominators are the same now, we can add both of the numerators together.
(30 + 17) / 100
47/100
The answer is: 47/100 or 0.47.
