Yuto is correct because he isolated the variable correctly and reversed the inequality symbol.
x < 3
Answer:15/2
Step-by-step explanation:
Reduce the index of the artical and exponent with 2 and get 3x18a. Calculate the product and get 54a.
In the
plane, we have
everywhere. So in the equation of the sphere, we have

which is a circle centered at (2, -10, 0) of radius 4.
In the
plane, we have
, which gives

But any squared real quantity is positive, so there is no intersection between the sphere and this plane.
In the
plane,
, so

which is a circle centered at (0, -10, 3) of radius
.
