Answer:
ooh this hard um...
Step-by-step explanation:
isn't that impossible?
Well, the answer quite simple ....there are 4! ways to arrange these numbers...and as 4! = 4*3*2*1 = 24
hence 24 is the correct answer....
u can also remember it by theorem of multiplication as.....in first place (I.e. first code can be any no. out of 4,5,2&7 ....so 4*.....
as first place is acquired by a certain no. that leaves three no. to fill third place and when third place I'd occupied it leaves 2 numbers to fill second place and lastly only one no. to fill the last place .....so it's result will be like 4*3*2*1.
I know this is pretty much confusing ....but still I tried my best....
if anything troubles u here feel free to ask me
Answer:
40600
Step-by-step explanation:
(4 * 10^4) + (6 * 10^2) =
= 4 * 10000 + 6 * 100
= 40000 + 600
= 40600
Answer:
(x,y) = (x, -2x²+6x+8), X∈R
Step-by-step explanation:
y= -2x²+6x+8
y=-2(x-4)×(x+1)
-2x²+6x+8= -2(x-4)×(x+1)
x∈R
(x,y) = (x, -2x²+6x+8), x∈R
Step-by-step explanation:
f(x) = 8 - 3x
when x =3, then
f(3) = 8 - 3×3
=8-9
=-1
