Find the radius of x2 plus y2 equals 9?
3
How do you graph x2 plus y2 is less than or equal to 9?
It is the circular disc with centre at the origin and radius = 3 units.
What is the standard form of the equation of the conic section given below x2-y2-6x-2y 60?
Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68
What is the slope of a line passing through the points 1 9 and -3 16?
The equation to figure out a slope is y1 - y2 / x1 - x2. In (1,9) and (-3,16), 9 is y1 and 16 is y2. 1 is x1 and -3 is x2. Now you have -7/4, which is your slope!
The equation for the circle below is x2 plus y2 81. What is the length of the circle's radius?
9 (APEX)
