Answer:
The sequence is a function
Step-by-step explanation:
Given
Sequence: 
; 
Required
Is the sequence a function
To determine if the sequence is a function or not, we start by calculating its range from the domain:
When n = 0;
When n = 1: 
When n = 2; 
When n = 3; 
This implies that:
The domain (n) and the range (An) can be represented as:
![\left[\begin{array}{c}n&-&0&1&2&3\\-&-&-&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dn%26-%260%261%262%263%5C%5C-%26-%26-%26%5Cend%7Barray%7D%5Cright%5D)
![\left[\begin{array}{c}A_n&-&100&175&250&325\\-&-&-&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7DA_n%26-%26100%26175%26250%26325%5C%5C-%26-%26-%26%5Cend%7Barray%7D%5Cright%5D)
<em>The above shows that the sequence is a one to one relation and a one to one relation is always a function.</em>
Answer:
25.08
Step-by-step explanation:
do 76 ÷ 100, and then multiply that by 33
Answer:
4
Step-by-step explanation:
since the fraction is 1/4 you can multiply 4 by 4 and get sixteen and 4x1=4
Slope=m=y/x=rise/run=(y1-y2)/(x1-x2)
Labeling the question; 0=x1, 32=y1, 100=x2, 212=y2
so just go ahead and fill the numbers in;
(32-212)/(0-100)=(-180/-100)=1.8
so therefore, the slope is at 1.8
Answer:
Infinitely many solutions.
Step-by-step explanation:
5x-8y=-11
-10x+16y=22
---------------------
2(5x-8y)=2(-11)
-10x+16y=22
---------------------
10x-16y=-22
-10x+16y=22
---------------------
0+0=0
infinitely many solutions
