P(x)=-0.001x2+3x-1800

P=−0.001x+3−1800/x

Step-by-step explanation:

Write the problem as a mathematical expression.

P(x)=−0.001x²+3x−1800/x

Divide each term in Px=−0.001x²+3x−1800 by x.

Px/x=−0.001x²/x + 3x/x + −1800/x

Cancel the common factor of x.

P=−0.001x²/x+3x/x + −1800/x

Simplify each term.

P=−0.001x+3−1800/x

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
