Final answer:

The distance from the point (2, 3, -2) to the plane 4x-4y-7z=-71 is calculated using the formula for the distance from a point to a plane and is found to be 9 units.

Step-by-step explanation:

The student is asking how to find the distance from a point to a plane. The point given is (2, 3, -2) and the equation of the plane is 4x-4y-7z=-71. The distance D from a point (x0, y0, z0) to a plane Ax+By+Cz+D=0 can be calculated using the formula:

D = |A*x0 + B*y0 + C*z0 + D| / √(A2 + B2 + C2)

Substituting the point into the equation, we get:

D = |4*2 - 4*3 - 7*(-2) - (-71)| / √(42 + (-4)2 + (-7)2)

D = |8 - 12 + 14 + 71| / √(16 + 16 + 49)

D = |81| / √(81)

D = 81 / 9

D = 9

Therefore, the distance from the point (2, 3, -2) to the plane 4x-4y-7z=-71 is 9 units.
