Audrina constructed a proof that quadrilateral PQRS is a rectangle.
In the proof below, she started with a pair of observations about the plot of quadrilateral PQRS on the coordinate plane.
With which pair of observations did Audrina start her proof?
A) Slope of PQ = Slope of RS = 3 ; Slope of PS = Slope of QR = 1/3
B) Slope of PQ = Slope of RS = 3: Slope of PS = Slope of QR = − 1/3
C) PQ = RS = 2√10 ;PS = QR = √17
D) PQ = RS = 6; PS = QR = 4

B) Slope of PQ = Slope of RS = 3: Slope of PS = Slope of QR = − 1/3

Step-by-step explanation:

slope PQ =3 and -1/3 is the slope of its perpendicular line

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

alright well the answers to your question is
