Answer:
(a - b)(a² + ab + b²)
Step-by-step explanation:
The difference of cubes is expressed as:
a³-b³
Using trial and error:
a³-b³
Check (a - b)(a² + ab + b²)
Expand
(a - b)(a² + ab + b²)
= a(a²)+a(ab)+a(b²)-a²b-ab²-b³
= a³+a²b+a(b²)-a²b-ab²-b³
Collect the like terms
= a³+a²b-a²b+ab²-ab²-b³
= a³-b³
Hence the required option is
F(x)=2ˣ
f(x)
(x,y)
(0,1)
(1,2)
(2,4)
(3,8)
(4,16)
(5,32)
(6,64)
(7,128)
(8,256)
(9,512)
(10,1024)
h(x)
(x,y)
(0,8)
(1,10)
(2,18)
(3,38)
(4,76)
(5,138)
(6,230)
(7,358)
(8,528)
(9,736)
(10,1018)
so somwehre between x=9 and x=10
hmm
f(9.5)=724.007
h(9.5)=874.875
go to 9.75
f(9.75)=944.609
h(9.75)=861.078
up
9.9
f(9.9)=955.426
h(9.9)=988.199
up
9.95
f(9.95)=989.119
h(9.95)=1003.02
up
9.99
f(9.99)=1016.93
h(9.99)=1014.99
a bit down
9.98
f(9.98)=1009.9
h(9.98)=1011.99
a bit up
9.985
f(9.985)=1013.41
h(9.985)=1013.49
pretty close, ya
so about at 9.985=x
if we graphed, we get that x=9.98512070914982..., so we are pretty close
Answer:
I believe it would be 1400
Step-by-step explanation:
If it is multiple choice this would probably be the best choice
Answer:
(7,4)
Step-by-step explanation:
The midpoint formula is:
Let (5,6) be x₁ and y₁ and let's let (9,2) be x₂ and y₂. Thus, the midpoint is:
Add:
Divide by 2:
So, our midpoint is (7,4).
And we're done!
