Please help, pre calculus

D.

Step-by-step explanation:

√(x - 6) > 0, because √(x - 6) is in denominator.

√(x - 6) >0

(x - 6)>0

x > 6, so domain is (6, ∞). This is C. or D.

1/√(x - 6)  cannot be negative because 1 >0, and √(x - 6) ≥0.

So,range cannot have negative values. And the answer is D.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
