Given a sequence is defined by the explicit definition tn=n^2+n.... (questions attached)
1 answer:
Question 1: The correct answer is Option 3: 20
Question 2: The correct answer is Option 3: 27
Step-by-step explanation:
We put the term number as value of n in explicit formula to find the term.
<u>Question 1:</u>
Given
To find t4, we will put t=4 in explicit formula
The correct answer is Option 3: 20
<u>Question 2:</u>
Given, the explicit formula
We have to find the 5th term, putting n=5 in the explicit formula
The correct answer is Option 3: 27

Answer:
(0,3) ; (2,3) ; (0,0) ; (3.5,0)
Step-by-step explanation:
Firstly, we have to plot all the giving inequalities as constraints
Not to forget, f(x) can be written as y
Kindly find the plot as an attachment
Upon plotting, we have the following vertices;
(0,3) ; (2,3) ; (0,0) ; (3.5,0)
Here you go! I’m not sure if they want it in decimal form…
Answer:
None of them are irrational.
Step-by-step explanation:
An Irrational Number is a real number that cannot be written as a simple fraction.
Therefore:
-4 can be written as -4/1
2/9 is already in fraction
8.26 can be written as 826/100
11 can be written as 11/1
None of them are irrational.
However numbers like are irrational as they can not be represented as fractions.
