.Given:

ToDetermine: The value of

Solution


Hence, f(1) + g(2) = -1
Answer:
The common ratio is 4
Step-by-step explanation:
We need to divide a term by the previous term to find the common ratio in a geometric sequence:
64 ÷ 16 = 4
256 ÷ 64 = 4
By doing it twice we can confirm that the common ratio is 4
8(4a+2b)
The equivalent is 32a+16b (B)
The answer would be choice C.
Perpendicular lines cross each other and form a right angle as you can see marked in the third picture.
