Answer:
Option D Both students could be correct. Because the numbers are given in the original sequence, it is possible to find a common difference and common ratio between the successive terms.
Step-by-step explanation:
A geometric sequence has a common ratio. Here, that ratio would be 11/-5.5 = -2 if the sequence is geometric. That ratio would mean the next two terms are ...
11 × -2 = -22
-22 × -2 = 44
__
An arithmetic sequence has a common difference. Here, that difference would be 11 -(-5.5) = 16.5 if the sequence is arithmetic. That difference would mean the next two terms are ...
11 +16.5 = 27.5
27.5 + 16.5 = 44
__
These descriptions match those offered by the students, so both could be correct.
I think it might be pairs 2 & 3
Answer:
K=-2.5
Step-by-step explanation:
because the line is in the middle of 2 and 3 and is below which means that it is negative
Given:
The graph of a function.
To find:
The domain on which of the following function is increasing.
Solution:
Domain is the set of x-values or input values.
From the given graph it is clear that the vertex of the given function is at (4,75).
Before the point (4,75) the graph is increasing and after the point (4,75) the graph is decreasing.
The function is defined for 
.
Since the graph is increasing when 
, therefore the function is increasing over the interval [0,4].
Therefore, the domain on which of the following function is increasing is [0,4].
Multiply 9 and 5 and you get 45.
