Answer:

Table 1

Step-by-step explanation:

In a function, you are not allowed to have two of the same x-values. Table 1 is the only one to show this.

Table 2 has two (-5)s in the x-column, Table 3 has two (-2)s, and Table 4 has two (-4)s.

A self own company charges $40 per month +0.05 cents for each text message sent.Select expression is there a percent of cost in
kondaur [170]
<h3>The monthly cost of cell phone is A  =  40 + 0.005 m</h3>

Step-by-step explanation:

The monthly fixed charges by mobile company = $40

The cost of sending each text message  = 0.05 cents

Now, 100 cents  = 1 dollar

⇒ 1 cent  =$ (\frac{1}{100} )

⇒ 0.05  cent s =$ (\frac{1}{100}  \times 0.05)  =0.0005

Also, the number of text messages send  =  m

So, the cost of sending m text message  = m x ( cost of 1 text )

= m x ( $ 0.0005) = 0.0005 m

Now, Total bill = Fixed rate + cost of m texts

⇒ A  =$40  +  $ 0.0005 m

Hence, the monthly cost of cell phone is A  =  40 + 0.005 m

Eleven members of the Middle School Math Club each paid the same amount for a guest speaker to talk about problem solving at the
tiny-mole [99]
The missing digit is number 3. The total amount should be $132

I multiplied 11 by the numbers 10 and above to get the possible three digit answer who has 1 as the first digit and 2 as the last digit.

11 x 10 = 110
11 x 11 = 121
11 x 12 = 132

The 11 members of the Middle School Math club each paid $12 for a guest speaker.

Expand<br> (2x - 3)4 <br><br> Can you help me expand this by using the binomial theorem?
saw5 [17]

The value of expanding (2x -3)^4 is 16x^4  + 96x^3  +216x^2 -216x + 81

<h3>How to expand the expression?</h3>

The expression is given as:

(2x -3)^4

Using the binomial expansion, we have:

(2x -3)^4 = ^4C_0 * (2x)^4 * (-3)^0 +^4C_1 * (2x)^3 * (-3)^1 + ^4C_2 * (2x)^2 * (-3)^2 + ^4C_3 * (2x)^1 * (-3)^3 + ^4C_4 * (2x)^0 * (-3)^4

Evaluate the combination factors.

So, we have:

(2x -3)^4 = 1 * (2x)^4 * (-3)^0 + 4 * (2x)^3 * (-3)^1 + 6 * (2x)^2 * (-3)^2 + 4 * (2x)^1 * (-3)^3 + 1 * (2x)^0 * (-3)^4

Evaluate the exponents and the products

(2x -3)^4 = 16x^4  + 96x^3  +216x^2 -216x + 81

Hence, the value of expanding (2x -3)^4 is 16x^4  + 96x^3  +216x^2 -216x + 81
