Brian has 2 parents, 4 grandparents, 8 great-grandparents, and so on. a. Write an explicit formula for the number of
ancestors Brian has in a generation if
he goes back to the nth generation.

b. Write a recursive formula for the number of
ancestors Brian has in a generation if
he goes back to the nth generation.

(PLEASE EXPLAIN WHY)

Assuming the ancestors are distinct (very unlikely), each generation is double the size of the following generation. So

15

generations back will be

2

15

=

32768

ancestors.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
