Vedmedyk [2.9K]

Answer:

Katrina will have to pay $21.02 this month.

Step-by-step explanation:

The cost per text message = $0.19

Last month credit = $9.50

The number of text messages sent this month = 158

So, the total cost of 158 texts = 158 x cost per text

= 158 x $0.19 = $ 30.52

So, her total bill = The amount spent on texts - The credit amount

= $ 30.52 - $9.50 = $21.02

So, Katrina will have to pay $21.02 this month.

HURRY 20 POINTS!!!!! Given the geometric sequence an = 6(5)n − 1, which of the following values for n lies in the appropriate do

Lapatulllka [165]

<h2>Answer:</h2>

n = 1

<h2>Explanation:</h2>

Here we have the following Geometric Sequence:

$a_{n} = 6(5)^{n-1}$

Where:

$a=6 \ \text{First term} \\ \\ r=5 \ \text{Common ratio} \\ \\ n: \ \text{Number of terms}$

The first term occurs when $n=1$ . Next the second term occurs when $n=2$ , the third term when $n=3$ and so on. Therefore, the appropriate value of n that lies on the domain for n is $n=1$
