ou have two parents, four grandparents, eight great-grandparents, and so forth. (a) If all your ancestors were distinct, what would be the total number of your ancestors for the past 39 generations (counting your parents' generation as number one)? (Hint: Use the formula for the sum of a geometric sequence.) (b) Assuming that each generation represents 25 years, how long (in years) is 39 generations? yr (c) The total number of people who have ever lived is approximately 100 billion, which equals 1011 people. Compare this fact with the answer to part (a). What can you deduce? (Select all that apply.) Some of my ancestors must not have had children. Some ancestors on different branches of the family tree must be the same. People have been living on earth for less than 1,100 years. There could not have been 39 generations in my line of ancestry.
Answer:
Part A:
[tex]2^{40}-2\\=1.0995*10^{12} ancestors[/tex]
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:
[tex]2+2^2+2^3+.........+2^{39}[/tex]
Now, Above series will become:
[tex]2[1+2+2^2+......+2^{38}][/tex]
From geometric Sequence:
[tex]2[\frac{2^{38+1}-1}{2-1} ][/tex]
[tex]2^{40}-2\\=1.0995*10^{12} ancestors[/tex]
Part B:
Generations Age=years*Number of generations
Generations Age=25*39=975 years
Part C:
Number of people lived= 10^11
Ancestors=[tex]1.0995*10^{12} ancestors[/tex]
[tex]10^{11}<1.0995*10^{12}[/tex]
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.Dilations
If ABCD is dilated by a factor of Į, the
coordinate of D' would be
9514 1404 393
Answer:
D'(2, -1)
Step-by-step explanation:
Dilation about the origin by factor k multiplies each coordinate by that factor:
(x, y) ⇒ (kx, ky)
For k = 1/3, this is ...
(x, y) ⇒ (x/3, y/3)
D(6, -3) ⇒ D'(6/3, -3/3) = D'(2, -1)
Calculate the rate of change.

A gear with a diameter of 12.0 inches makes 35 revolutions every three minutes. Find the linear and angular velocities of a point on the outer edge of the gear. Give your answers in both exact and approximate forms.
Answer:
Angular velocity: [tex]\omega = \frac{7\pi}{18} \,\frac{rad}{s}[/tex] ([tex]1.222\,\frac{rad}{s}[/tex])
Linear velocity: [tex]v = \frac{14\pi}{3}\,\frac{m}{s}[/tex] ([tex]14.661\,\frac{m}{s}[/tex])
Step-by-step explanation:
The gear experiments a pure rotation with axis passing through its center, the angular ([tex]\omega[/tex]), in radians per second, and linear velocities ([tex]v[/tex]), in inches per second, of a point on the outer edge of the element are, respectively:
[tex]\omega = \frac{2\pi}{60}\cdot \dot n[/tex] (1)
[tex]v = R\cdot \omega[/tex] (2)
Where:
[tex]\dot n[/tex] - Rotation rate, in revolutions per minute.
[tex]R[/tex] - Radius of the gear, in inches.
If we know that [tex]\dot n = \frac{35}{3}\,\frac{rev}{min}[/tex] and [tex]R = 12\,in[/tex], then the linear and angular velocities of the gear are, respectively:
[tex]\omega = \frac{2\pi}{60}\cdot \dot n[/tex]
[tex]\omega = \frac{7\pi}{18} \,\frac{rad}{s}[/tex] ([tex]1.222\,\frac{rad}{s}[/tex])
[tex]v = R\cdot \omega[/tex]
[tex]v = \frac{14\pi}{3}\,\frac{m}{s}[/tex] ([tex]14.661\,\frac{m}{s}[/tex])

Answer:
a=11
Step-by-step explanation:
Let's solve your equation step-by-step.
√a+5=4
Solve Square Root.
√a+5=4
a+5=42(Square both sides)
a+5=16
a+5−5=16−5(Subtract 5 from both sides)
a=11

16 minutes= 6 bushes trimmed
how many minutes would it take for 30 bushes to be trimmed?
For each equation, find y when x=-3. Then find x when y = 2
1. y = 6x + 8
⬇ Hey, the answer is down below! :) ⬇
For y: x = -3
For y it stays the same.
For x: y = 2
For x it stays the same too.
For 1.): [tex]x = \frac{1}{6}y + \frac{-4}{3}[/tex]
Step-by-step explanation:
For y there is no step-by-step explanation unfortunately.
For x there isn't a step-by-step explanation too unfortunately.
⬇ For 1.) there is a step-by-step explanation! ⬇
For step 1 we should flip the equations.
6x + 8 = y
For step 2 we should add -8 to both sides.
6x + 8 + − 8 = y + −8
= 6x = y − 8
For step 3 we should divide both sides by 6.
[tex]\frac{6x}{6} = \frac{y - 8}{6}[/tex]
= x = [tex]x = \frac{1}{6}y + \frac{-4}{3}[/tex]
In result we should have [tex]x = \frac{1}{6}y + \frac{-4}{3}[/tex] as the answer!

A man is three times as old as his daughter. If the difference in their ages is 36 years, find the ages of the father and daughter.
Answer:
man's age = 54
daughter's age = 18
Step-by-step explanation:
x = man's age
y = daughters age
x = 3y
x - y = 36
substitute for x:
3y -y = 36
2y = 36
y = 18
x = 54
If a man has a daughter who is three times his age. The father and daughter will be 54 and 18, respectively, assuming their ages are 36 years distant.
What is an equation?Equations are statements that affirm the equivalence of two expressions that are joined by the equals symbol "=". An equal sign ("=") links two expressions together to form an equation. The two expressions on each side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.
It is given that, A man is three times as old as his daughter. If the difference in their ages is 36 years,
We have to find the ages of the father and daughter.
Suppose the age of the father and daughter will be x and y respectively.
If the man is three times as old as his daughter,
x = 3y
If the difference in their ages is 36 years
x - y = 36
Put the value of x as,
3y -y = 36
2y = 36
y = 18
x = 54
Thus, if a man has a daughter who is three times his age. The father and daughter will be 54 and 18, respectively, assuming their ages are 36 years distant.

Write the slope-intercept form of an equation of the line that passes through the given point and is perpendicular to the graph of the equation. (-8,5) y = -4x +2
Answer:
y = 1/4x + 7
Step-by-step explanation:
A perpendicular line will have an opposite reciprocal slope, so the slope will be 1/4
Plug in the given point and slope into y = mx + b, then solve for b
y = mx + b
5 = 1/4(-8) + b
5 = -2 + b
7 = b
Plug in b and the slope into y = mx + b
y = 1/4x + 7
So, the equation of the line is y = 1/4x + 7

Answer:
The sum of the series is 3/2
Step-by-step explanation:
Given
1 + 1/3 + 1/3^2 + ....
Required
The sum of the series
This implies that we calculate the sum to infinity.
We have:
[tex]a = 1[/tex] -- The first term
First, calculate the common ratio (r)
[tex]r = \frac{1}{3^2} / \frac{1}{3}[/tex]
Change to product
[tex]r = \frac{1}{3^2} * \frac{3}{1}[/tex]
Solve
[tex]r = \frac{1}{3}[/tex]
The sum of the series is then calculated as:
[tex]S_{\infty} = \frac{a}{1 - r}[/tex]
[tex]S_{\infty} = \frac{1}{1 - 1/3}[/tex]
Solve the denominator
[tex]S_{\infty} = \frac{1}{2/3}[/tex]
Express as product
[tex]S_{\infty} = 1 * \frac{3}{2}[/tex]
[tex]S_{\infty} = \frac{3}{2}[/tex]
