Isabel is pulling water up from an old-fashioned well. She lifts the bucket of water at a rate of 4 ft/s, and after 1 s, the bucket is 1 ft below the top of the well. What is the equation in point-slope form of the line that represents the height of the bucket relative to the top of the well?

The equation in point-slope form of the line that represents the height of the bucket relative to the top of the well is .

Step-by-step explanation:

The point-slope form of the equation of the line is represented by the following expression:

(1)

Where:

- Time, measured in seconds.

- Height below the top of the well, measured in feet.

, - Known information of the well, measured in seconds and feet, respectively.

- Slope, measured in feet per second.

If we know that and , then the equation in point-slope form of the line is:

The equation in point-slope form of the line that represents the height of the bucket relative to the top of the well is .

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
