A gallon of milk cost $2.90 in 2002. In 2018, it cost
lutik1710 [3]

Answer:

<em>The cost of a gallon of milk changed 31%</em>

Step-by-step explanation:

<u>Percent Change</u>

Is the difference between two values of the same variable in different times or conditions, expressed as a percentage of the original value.

The formula is:

\displaystyle Pc=\left |\frac{v1-v2}{v1}  \right |\cdot 100\%

Where

v1 = original value

v2 = final value

The gallon of milk cost v1=$2.90 in 2002 and v2=$3.80 in 2018. The percent change is:

\displaystyle Pc=\left |\frac{2.90-3.80}{2.90}  \right |\cdot 100\%

\displaystyle Pc=\left |\frac{-0.9}{2.90}  \right |\cdot 100\%

Pc = 31%

The cost of a gallon of milk changed 31%

How would you write 1 - x^4 before you divide it by x - 1?
devlian [24]
Order your terms by the powers of exponents in decreasing order (as is the case with pure number division hundreds, tens, ones, tenths, etc, etc) as x^n, x^n-1 etc...

(-x^4+1)/(x-1)
-x^3 rem -x^3-1
-x^2 rem -x^2-1
-x     rem -x-1
-1     rem 0

(x-1)(-x^3-x^2-x-1)

(x-1)(-x^3-x-x^2-1)

(x-1)(-x(x^2+1)-1(x^2+1))

(x-1)(-x-1)(x^2+1)
