HELP!! Which of the following information would prove the quadrilateral ABCD is a rectangle?

Slope of AB = 2, slope of BC = -1/2

Slope of CD = 2, slope of DA = -1/2

Note how the slopes of AB and BC are negative reciprocals. Multiplying 2 and -1/2 together will result in -1. This shows us that AB is perpendicular to BC. Perpendicular slopes always multiply to -1 (assuming neither line is vertical). The same can be said about CD and DA as well. The segments being perpendicular mean we have four right (or 90 degree) angles forming. A rectangle is defined as a quadrilateral with four right angles.

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

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
