Well I mean 10 x 10 = 100 so if we divide 800 by 100 we get 8. One square represents 8.

Maslowich

Answer:

Part A:

$2^{40}-2\\=1.0995*10^{12} ancestors$

Part B:

Generations Age=25*39=975 years

Part C:

Some ancestors on different branches of the family tree must be the same.
There could not have been 39 generations in my line of ancestry.

Step-by-step explanation:

Given Data:

Two Parents, Four Grand Parents, Eight great Grand Parents.

Generation=39

Solution:

Part A:

From given data Following series is made:

$2+2^2+2^3+.........+2^{39}$

Now, Above series will become:

$2[1+2+2^2+......+2^{38}]$

From geometric Sequence:

$2[\frac{2^{38+1}-1}{2-1} ]$

$2^{40}-2\\=1.0995*10^{12} ancestors$

Part B:

Generations Age=years*Number of generations

Generations Age=25*39=975 years

Part C:

Number of people lived= 10^11

Ancestors= $1.0995*10^{12} ancestors$

$10^{11}$

It means ancestors are not distinct, it means:

Some ancestors on different branches of the family tree must be the same.
There could not have been 39 generations in my line of ancestry.

Wayne is solving a system of linear equations. y = −34x + 5y = -34x + 5 x = −2x = -2 To solve this system, he graphed the line y

blondinia [14]

Wayne is solving the linear system of equations using the graphical method, but it can also be solved analytically.
We will solve the system of equations analytically to find in which point Wayne will find the solution graphically.
Resolving we have:
y = -34x + 5 (Eq1)
x = -2 (Eq2)
Substituting (Eq2) in (Eq1) we have
y = -34 * (- 2) + 5
y = 73
Therefore the point will be
(x, y) = (- 2,73)
answer
the point will have found the solution of this system of linear equations is (-2,73)
