Equation of circle:
(x+2)^2 + (y+8)^2 = 17
Point (-6, -7)
(-6+2)^2 + (-7+8)^2 = 17
(-4)^2 + (1)^2 = 17
16 + 1 = 17
17 = 17
Answer is YES
Answer:
The coordinates of the resulting point, T' are (2,-6)
Step-by-step explanation:
The point T(-2,-6) is reflected over the y-axis. What are the coordinates of the resulting point, T'?
Reflection across y-axis:
When a point (x,y) is reflected across y-axis the resulting point have coordinates (-x,y)
So, we are given point T (-2,-6)
Reflection across y-axis we get T'
T' (2,-6)
So, The coordinates of the resulting point, T' are (2,-6)
This question is much easier than the last one. As we can see the yellow are is the same as the bottom area with the same shape. And the area of the 2 hemispheres adds together to a full circle area: 3^2*pi=9pi
Area of yellow region=(36-9pi)/2=18-9/2pi=3.862 and round this to the nearest tenth getting 3.9.
1/4 * x + 1/4 * 4
(the * are multiplication signs)
