Answer:
Option (3)
Step-by-step explanation:
Explicit formula of the sequence is,

From this explicit formula,
First term of the sequence will be,


Second term of the sequence,

= 13
3rd term of the sequence,

= 31
Sequence formed,
7, 13, 31 ..........
From the given options,
Recursive formula,



= 13



= 39 - 8
= 31
Sequence formed from this recursive formula will be,
7, 13, 31........
Therefore, Option (3) will be the answer.
Answer:
This is your answer If I'm right so.
Please mark me as brainliest. thanks!!
Sn=n/2[2a+(n-1)d]
s7 means n=7
a7=7/2[2(13)+(7-1)(3)]=7/2(44)=154
Ans:C
Answer:
To create function h, function f was translated 2 units right
, translated 4 units up and reflected across the x axis
Step-by-step explanation:
Given


Required
Complete chart
First: f(x) was translated right by 2 units
The rule of right translation is 
So, we have:


Next: f'(x) was translated up by 4 units
The rule of down translation is 
So, we have:


Lastly, f"(x) was reflected across the x-axis;
The rule of this reflection is: 
So, we have:

![h(x) = -[(x+2)^3 + 4]](https://tex.z-dn.net/?f=h%28x%29%20%3D%20-%5B%28x%2B2%29%5E3%20%2B%204%5D)

Answer: It is worth it.
Step-by-step explanation:
If a customer sends 101 - 200 texts in a month, they get charged 8 cents per text.
If they send 201 - 300, they get charged 6 cents per month.
If you have sent 200 texts, your charge for the month will therefore be:
= 200 * 8
= $16.00
If you send the 201th text, you will be charged 6 cents per text. Total charge would be:
= 201 * 6
= $12.06
<em>If you send 1 more text, it will be worth it because you will save:</em>
<em>= 16 - 12.06</em>
<em>= $3.94</em>
