Complete Question:
Find the coordinates of the point after the described reflection. Give the distance between the point and its reflection. R(-5, 8) is reflected across the x-axis _____________.
Answer:
![R' = (-5,-8)](https://tex.z-dn.net/?f=R%27%20%3D%20%28-5%2C-8%29)
The distance is 16 units
Step-by-step explanation:
Given
![R = (-5,8)](https://tex.z-dn.net/?f=R%20%3D%20%28-5%2C8%29)
Solving (a): Reflection across x-axis
The rule is:
![R(x,y) ==> R(x,-y)](https://tex.z-dn.net/?f=R%28x%2Cy%29%20%3D%3D%3E%20R%28x%2C-y%29)
So, the reflection of
is:
![R' = (-5,-8)](https://tex.z-dn.net/?f=R%27%20%3D%20%28-5%2C-8%29)
Solving (b): The distance between R and R'
Distance (d) is calculated as:
![d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x_1%20-%20x_2%29%5E2%20%2B%20%28y_1%20-%20y_2%29%5E2%7D)
Where:
---- ![(x_1,y_1)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29)
--- ![(x_2,y_2)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29)
This gives:
![d = \sqrt{(-5- -5)^2 + (-8- 8)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28-5-%20-5%29%5E2%20%2B%20%28-8-%208%29%5E2%7D)
![d = \sqrt{(0)^2 + (-16)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%280%29%5E2%20%2B%20%28-16%29%5E2%7D)
![d = \sqrt{256}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B256%7D)
![d = 16](https://tex.z-dn.net/?f=d%20%3D%2016)
<em>The distance is 16 units</em>
Answer:
1:200
5.6 cm^2 : y (as actual area)
y = 200 mutifly 5.6 cm^2
y= 1120 cm^2
We know 1m =100cm
so, 1m^2 =100cm x 100 cm = 1000cm^2
y= 1120 m^2/ 100x100
= 0.112 m^2
Step-by-step explanation:
2.00/6 = $0.33 rounded to the nearest penny, it actually is $0.333333333333 (infinite)
