Answer:
–2.7, –9, –30, –100, ...
–1, 2.5, –6.25, 15.625, ...
8, 0.8, 0.08, 0.008, ...
Explanation:
A geometric sequence is a sequence with the ratio between two consecutive terms constant. This ratio is called the common ratio.
now check all the sequence one by one.
For sequence –2.7, –9, –30, –100, ...
r =
=
=
We see that, all the ratios are same.
So this is geometric sequence.
For sequence –1, 2.5, –6.25, 15.625, ...
r =
This is also geometric sequence.
For sequence 9.1, 9.2, 9.3, 9.4, ...
In this sequence, common ratio is not same.
So, it is not a geometric sequence.
For sequence 8, 0.8, 0.08, 0.008, ...
Common ratio is same so, it is geometric sequence.
For sequence 4, –4, –12, –20, ...
Common ratio is not same. So, it is not geometric sequence .
Answer:
The solution is (4, 0)
Step-by-step explanation:
Using Linear combination method to solve:
Since "e" have the same coefficient in both equation with opposite operator; we will add.
Divide both side by coefficient of d which is 3
Since d = 4; put 'd' into any of the equation to get 'e'
Therefore, the solution is (4, 0)
Answer:
Option A is correct.
The domain of the g(x) is {x | x is a real number}
Step-by-step explanation:
The graph of the step function: g(x)=
Floor function is defined as the function that gives the highest integer less than or equal to x.
The graph of function: g(x)= where x is the independent variable as shown below;
Domain of any function is the complete set of possible values of the independent variable
Therefore, the domain of the function g(x) is the set of all real numbers or we can represent this as {x | x is a real number}.
