Answer:
The distance is 4.
Step-by-step explanation:
The shortest distance from the point (4,2) to the line y=-2, in this case, would be a straight line perpendicular to y=-2.
For each and every value of "x" on the line, y = -2. The shortest distance occurs at y(4) = - 2.
At this point the distance is:
![d^{2} =(4 - 4)^{2} + (2-(-2))^{2} \\d^{2} =4 ^{2}\\\\d = 4](https://tex.z-dn.net/?f=d%5E%7B2%7D%20%3D%284%20-%204%29%5E%7B2%7D%20%2B%20%282-%28-2%29%29%5E%7B2%7D%20%5C%5Cd%5E%7B2%7D%20%3D4%20%5E%7B2%7D%5C%5C%5C%5Cd%20%3D%204)
The distance is 4.
The answer is 9.2, because when the number behind the number being rounded is 5 or above, you round up. if the number was 9.14, it would be rounded down to 9.1 :)
Answer:
(x +4)^2 + (y-2)^2 = 16
Step-by-step explanation:
We can write the equation for a circle with the formula
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
We know the center is at (-4,2) and the radius is 4
(x- -4)^2 + (y-2)^2 = 4^2
(x +4)^2 + (y-2)^2 = 16
