Which of the following characteristics of the set {(0.8), (8,0). (1 , 6), (6, 1), (2,4), (4, 2)} make it a function? А
The ordered pairs contain only integers.
B.
The ordered pairs demonstrate a pattern.
С
The ordered pairs do not repeat any of the x values.
D
The ordered pairs do not repeat any of the y values.

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

i think the answer is 90 hope this

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
