Answer:
Step-by-step explanation:
The general equation of a sphere is as follows:
In which the center is , and r is the radius.
In this problem, we have that:
So
Interior contained in the first octant:
The first octant is bounded by:
The xy plane, in which z is 0. The distance from the center of the sphere to the xy plane is 9.
The xz plane, in which y is 0. The distance from the center of the sphere to the xz plane is 4.
The yz plane, in which x is 0. The distance from the center of the sphere to the yz plane is 5.
This means that if the radius is higher than four, the sphere will cross into a different octant.
So the radius for the largest sphere is 4.
The equation is
Answer:
you want to isolate x so just add 16 to the right side (-4)
so -16 + x = -4
+16 +16
x=12
hope this helps :)
Answer:
when x is 5, y is -1
when x is 3, y is -4
