Answer:

2. ) {25}^{2x} - 1 = {125}^{3x} + 4

=> {25}^{2x} = {125}^{3x} + 4 +1

=> {(5)^(2)}^{2x} = {(5)^(3)}^{3x} + {5}^{1}

=> {5}^{4x} = {5}^{9x} + {5}^{1}

=> 4x = 9x + 1

=> 4x - 9x = 1

=> - 5x = 1

=> x = 1/-5

Write a polynomial in standard form with zeros at -2 and 3 !!!!! PLZ HELP
lara31 [8.8K]

If the zeros are -2 and 3, then the factored form would be

(x+2) and (x-3)  

-2+2 = 0 and 3-3 = 0

A polynomial is written as ax^2 + bx + c

Expand (x+2) (x-3) using FOIL: Multiply each tern in one set of parenthesis by each term in the other set and then simplify by combining like terms:

x*x + x*-3 + 2*x + 2*-3

x^2 -3x + 2x -6

Polynomial in standard form:

x^2 -x -6

In 2006 the state of nevada had two area codes how many phone numbers could nevada accommodate if the first digi cannot be zero
Aleks04 [339]
Answer: There are 16 million different phone numbers possible. 

First, let's find the number of possible phone numbers without the area code. There are 7 numbers in a phone number. There are 10 digits for each position. However, the first one can't be 1 or 0, so there are only 8 options.

Multiply the possibilities to find the total number.

8 x 10 x 10 x 10 x 10 x 10 x 10 = 8,000,000

Since, there are 2 different area codes, just multiply 8 million by 2 to get 16 million.

Examples of mean, median, and mode
valina [46]

Answer:

in a group of numbers (2,4,7,9,7,5,7,8,3)

The mean would be 5.2

The mode would be 7

The median would be 7

Explanation:

Say we have a group of numbers<u> (2,4,7,9,7,5,7,8,3)</u>

Lets start by finding the Median! *Remember, the median is the MIDDLE!

So, if the median is the middle, it would be 7.

Lets do the mode now. *Remember the mode is the one that happens the MOST!*

If we take a look at the numbers, we see that 7 occurs the most (it appears 3 times)

Our mode would be 7.

Lastly, lets do the mean. *You add and divide for the mean*

So, we start by adding all of the numbers together.

Basically, ( 2 + 4 + 7 + 9 + 7 + 5 + 7 + 8 + 3) you then get 52.

Next, we divide 52 by all the numbers that we added together (9)

And we get our mean: 5.2
