6. If A= {4,8} and B= {1,2,3,4), then find AxB, and also find the relation 'is double of.​

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

source:

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

15: 24

62.5%

step-by-step explanation:

60: 45 =12: 9 =4: 3 so the answer is 4: 3
