Question details:
consider a
sets={a1,a2,a3,a4,}and
a
setb={x1,x2,}.prove
that the
number of surjective mappings(ontofunctions) from a to b
is given by coefficient of
xr in the expansion
r! (ex-1)n.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

$9.41

step-by-step explanation:

beluga wheeeaaalle matt

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
