Across-country running coach needs to select four runners to compete in an upcoming cross-country race. there are currently six sophomores and four juniors available for this race. how many teams of four runners are available for the race if the team must include two sophomores and two juniors?

select one: a. 210 b. 90 c. 15 d. 360 e. 96 f. 2,025

f

step-by-step explanation:

f

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

i'm sure goog can you get that answer
