the answer is :
90 - 60 = 30
Answer:
<em>The 15th term is 10.25</em>
Step-by-step explanation:
<u>Sequences</u>
The given sequence:
-0.25, 0.5, 1.25, 2, 2.75...
can be categorized as an arithmetic sequence. To better know, we try to find a common difference between successive terms:
0.5 - (-0.25) = 0.75
1.25 - 0.5 = 0.75
2 - 1.25 = 0.75
Once we are certain it's an arithmetic sequence, we find the general term by using the formula:
Where n is the number of the term, a1 is the first term, and r is the common difference. We have already found that:
r=0.75
a1=-0.25
The 15th term (n=15) is:
The 15th term is 10.25
Answer: 27<AB<81
Step-by-step explanation:
We can generalize the triangle inequality theorem to say that the sum of the lengths of the two shorter sides must be greater than the length of the longest side.
Case 1: AB is the longest side
Case 2: BC is the longest side
So,
After simplifying the real and imaginary parts you'd get -8i
Answer:
Option C) for is not the correct way to define the given infinite sequence
Step-by-step explanation:
Given infinite sequence is
Option B) for is not the correct way to define the given infinite sequence
Now verify for is true for the given infinite sequence
That is put n=1,2,3,.. in the above function
When n=1,
When n=2,
When n=3,
and so on.
Therfore for is not the correct way to define the given infinite sequence
Therefore option C) is correct
