Answer:
Proof in explanation.
Step-by-step explanation:
I'm going to attempt this by squeeze theorem.
We know that 
is a variable number between -1 and 1 (inclusive).
This means that 
.
for all value 
. So if we multiply all sides of our inequality by this, it will not effect the direction of the inequalities.
By squeeze theorem, if
and 
, then we can also conclude that 
.
So we can actually evaluate the "if" limits pretty easily since both are continuous and exist at 
.
.
We can finally conclude that 
by squeeze theorem.
Some people call this sandwich theorem.
Square A:
Length = 13 inches
Height = 2 inches
Volume: 23 inches
-----------------------------
Square B:
Length = 5 inches
Height = 2 inches
<span>Volume: 10 inches
</span>
23 x 10 = <span>230 inches
</span>
VOLUME: 230 inches
us pascal triangle
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
each number is the sum of 2 above it and the 1's are on the outside because only 1 number is above them and its 1
so since its ^4 we use row 4 (actually the 5th because the top row is row zero)
these at the coefficients
so here is
1a^4b^0-4a^3b^1+6a^2b^2-4a^1b^3+1a^0b^4
or easier to see it vertically
notices how exponential start a 4 and 0 until 4 goes down to 0 and 0 goes up to 4
(3x - 1)
a = 3x
b = -1
1a^4b^0 = 1(3x)^4(-1)^0
-4a^3b^1 = -4(3x)^3(-1)^1
+6a^2b^2 ....
-4a^1b^3 .....
+1a^0b^4....
then write it horizontally
I think you see now, when you expand this you will have your answer
I think it’s -5 not sure tho but I don’t really get the question either so sorry if it doesn’t help
C.
4 + 3 7 + 3 1 0 + 3 1 3
