In January. The temperature in Fargo, North Dakota is -2 F. On the same day, the temperature in Cheyenne, Wyoming was 1 F. Write
zaharov [31]

Answer:

(a) 1 > -2 or -2 < 1

(b) 2 > 1 or 1 < 2

Step-by-step explanation:

Given

N = -2F --- North Dakota

C = 1F --- Cheyenne, Wyoming

Solving (a): Inequality to compare both temperatures

From the given temperatures, we can conclude that:

C > N or N < C

Because

1 > -2 i.e. 1 is greater than -2

or

-2 < 1 i.e. -2 is less than 1

Solving (b): Inequality to compare the absolute values of the temperatures

We have:

N = -2F

C = 1F

The absolute values are:

|N| = |-2|

|N| =2

|C| = |1|

|C| = 1

By comparison:

|N| > |C| or |C| < |N|

Because

2 > 1 i.e. 2 is greater than 1

or

1 < 2 i.e. 1 is less than 2

Which of the following polynomials is the expansion of (x - y)4? x4 - x3y + x2y2 - 2xy3 + y4 x4 -2x3y3 + y4 x4 - 2x3y + x 2y 2 -
sammy [17]

Answer:

(x-y)^4=x^4-x^3y+6x^2y^2-4xy^3+y^4.

Step-by-step explanation:

We want to find the polynomial that will result from expanding:

(x-y)^4.

Recall that we can use the Pascal's triangle to obtain the coefficient as:

1     4    6   4   1

Also note how the negative sign is going to alternate.

The <em>power of x </em>will decrease from left to right while the <em>power of y</em> increases from left to right

The expansion then becomes:

(x-y)^4=x^4-x^3y+6x^2y^2-4xy^3+y^4.
