Imagine that you are an explorer . You have just landed on an island and you decide that eventually you would like to bring your friends and realatives there to live.You notice however there aren't any pigs on the island,and you all have exotic tastes: you and your friends and relatives simply adore pigs' feet. (Ok use your imagination here! Pigs' feet are considered a delicay by some,although frankly, I don't see it...) You decide to leave a male and a female pig on the island,go back and get your friends,and return and three years. These pigs will produce THREE LITTERS OF BABIES EACH YEAR (ONE EVERY FOUR MONTHS). There are ALWAYS TWO MALES AND TWO FEMALES IN EACH LITTER.

1) IF ALL THE FEMALES, NO MATTER HOW YOUNG OR HOW OLD, HAVE A LITTER (AS DESCRIBED ABOVE) EVERY FOUR MONTHS AND NO PIGS DIE, HOW MANY PIGS WILL BE ON YOUR ISLAND WHEN YOU RETURN? CAN YOU FIND ANY PATTERNS?
EXPLAIN YOUR STRATEGY AND REASOING PLEASE!!!!!!!!!!!!!!!!!!!!!!!!!

i have a diagram..it shows the sector of a circle the circle has a radius of 10 cm and an arc length of 15 cm calculate the area of the sector?

ALSO Solve Xsquared + 3x - 5 = 0 Give solutions correct to 4 significant figures

do not know the starting point, but it went through like,---discovery of the wheel, what that allowed to be made, and what that find allowed to be made. I remember the clock and all of lits gears. Do you know the name of the series and or the narriator. This was probable 15 or so years ago

Find the largest possible volume of a cylinder inscribed in a sphere of radius 8 (cf. profile view above).

We need to maximize the following function r and h:
V= pi*r^2*h
Then we solve for r in terms of h obtaining:
r=
We thus obtain the following formula for V in terms of h alone:
V=
h varies over the interval [a,b], where
a =
b =
V has one stationary point at
h =
We conclude that the maximum possible volume of such a cylinder is:
V =

(7)/(cubicroot(x))-3*cubicroot(x^2)

I know that you can rewrite the cubic roots to x^(1/3) but I am confused on solving it. I also know about the + C on the end of the final answer as well.

There is a square grid. In the lower left corner is A and in the upper right is B. A diagonal is drawn from A to B and you are not allowed to go above it while travelling from A to B. You can only move right and up. In how many ways in an n x n grid can you travel from A to B? Prove your answer.

(I know that without the diagonal, there are (2n) C (n) ways.)

All the planets in the solar system orbit around the sun in elliptic (oval-shaped) orbits.The motion of all or most of the planets have other features in common....Can you identify 2 of those similarities?

okay these questions have to do with evolution!

1. There is a difference of only one amino acid in one chain of the hemoglobin of humans and gorillas. What might have caused this difference???!!!

2. If the amino acid sequences in the proteins of two organisms are similar, why willl their DNA also be similar?

3. Many biologists believe that the number of differences between the proteins of different species indicates how long ago the species diverged from common ancestors. Why do these biologists believe that humans, chimpanzees, and gorillas diverged from a common ancestor only a few million years ago?


the last ones long.s orry.

if you happen to know the answers to all or any of these please respond!!!!!!
