Plug in f(6) so it would be -2/3(6)+5= 1
So ur answer would be one
Hey how are you doing today?
We know that
The formula for combinations is
C=n!/[(n-r)!*r!]
where
n is the total number of objects you choose from
r is the number that you choose to arrange
in this problem
n=15 students
r=4 students
C=15!/[(15-4)!*4!]-----> C=15!/[11!*4!]---> (15*14*13*12*11!)/(11!*4*3*2*1)
C=(15*14*13*12)/(24)----->C=1365
the answer is
1365
75°+75°=150°
angles in a triangle add up to 180°
180°-150°=30°
c) x=30°
240 plz like my awnser it would mean alot
