use long multiplication to evaluate .
The correct answer is:
b.) f(n) = 3 • (-2)^(n-1)
Further explanation:
Given sequence is:
3, -6, 12, -24, ...
We have to find the common ratio first.
Common ratio is the ratio between two consecutive terms of a geometric sequence.
It is denoted by r.
So,
General formula for geometric sequence is:
Putting the values of a1 and r
Hence,
The correct answer is:
b.) f(n) = 3 • (-2)^(n-1)

Answer:
D: 3(x + 5)(x + 5)
Step-by-step explanation:
Try multiplying the last answer choice (D); the result is 3(x^2 + 10x + 25), or
3(x + 5)(x + 5).
The numerical representation and final elevation of the fish relative to sea level are :
- Final position = -13.52 + 7.8
- Final position = - 5.72
<u>Given the Parameters</u> :
Initial depth of fish = - 13.52
Change in elevation of fish = 7.8 feets
Positions below sea level are represented as negative values (-) ;
Hence, initial position of fish = - 13.52
Change in position = Rise in depth of 7.8 feets
<u>The numerical representation of the final position of the </u><u>fish</u><u> </u><u>can</u><u> </u><u>be</u><u> written thus</u> :
- Final position = Initial position + change in position
- Final position = - 13.52 + 7.8
Hence, the final position of the fish will be :
- Final position of fish = -13.52 + 7.8 = - 5.72
