Answer:

lim_{x \to 1} x^2 -8x -2 =-9

Step-by-step explanation:

For this case we want to find the following limit:

lim_{x \to 1} x^2 -8x -2

And we can find the limit distirbuting into each term like this:

\lim_{x \to 1} x^2 -8 lim_{x \to 1} x -lim_{x \to 1} 2

And replacing we got:

1^2 - 8*1 -2 = 1-8-2 = -9

So then the final answer for this case is:

lim_{x \to 1} x^2 -8x -2 =-9

kotykmax [81]

Answer:

18" X 18" X 36"

Step-by-step explanation:

Given a square base container of height h, let a side of the base =s

The volume of the container, V= s^2h

If the sum of its height and girth (the perimeter of its base) equals 108 in

4s+h = 108\\h = 108-4s

Substituting h=108-4s into V

V= s^2(108-4s)

We are required to determine the maximum volume of such container, first we take the derivative:

V'(s)= s(216-12s)

Optimizing:

s(216-12s)=0\\216-12s=0\\12s=216\\s=216 \div 12\\s=18

Recall that: h = 108-4s

h = 108-4(18)=108-72=36inch

The dimensions of the carton are 18" X 18" X 36".

Answer:

B.   (x - 6)(x + 2).

Step-by-step explanation:

x^2 - 4x - 12

We need 2 numbers whose product is the last number -12 and whose sum is the coefficient of x (-4).

These numbers are -6 and + 2.

So the factors are (x - 6)(x + 2).
