I heard somewhere that Venus presents the same side towards Earth at all times (confirmed by Earth-based radar). It might seem to make sense, as Venus produces the third-highest gravitational influence on the Earth, (after the Moon and Sun). Is this possible, even accounting for the sheer distance between the two bodies?

My daughter asked me this question today. She's 9. Something to keep in mind when answering :) I told her I thought they would explode. Then she asked what they would turn into. I said probably smaller pieces of whatever the stars were made of. She thinks maybe black holes, which sounds like a better answer to me. Anyone with better, more technical info, feel free!

Often environmentalists capture an endangered species and transport the species to a controlled environment where the species can produce offspring and regenerate its population. Suppose that six American bald eagles are captured, transported to Montana, and set free. Based on experience, the environmentalists expect the population to grow according to the model
P(t)= 500/ 1+83.33e^-0.162t
where t is measured in years.
a) determine the carrying capacity of the environment
b)what is the growth rate of the bald eagle?
c)what is the population after 3 years?
D)when will the population be 300 eagles?
e)How long does it take for the population to reach one-hhalf of the carrying capacity?

It's weird, we're always taught that positive and negative attract, protons and electrons attract, but nobody ever says why they attract. Similarly, why are objects attracted gravitationally?

Find the formula for a parabola with its vertex at (2,7) and with a second derivative of -4.

Find the formula for a function of the form y = A\sin(Bx) + C with a maximum at (3,6), a minimum at (9,-4), and no critical points between these two points.

Find the formula for a function of the form y = be^{-(x-a)^2/2} with its maximum at the point (0,8).

Find the formula for a quartic polynomial whose graph is symmetric about the y-axis and has local maxima at (-3,5) and (3,5) and a y-intercept of 2.

I am so confused. My math professor is horrible. I have no idea how to do these problems. I have looked in my book and I have asked other people and we cant figure out how to do these. PLEASE EXPLAIN!!! Thank you so mcuh!

This is based on gravity and if we want to find newtons do we first convert grams to kg and than times by 9.8 to get the Newtons?

we have to have it protected in something, and my teacher has to be able to take it out and put it back in, and you have to be able to see the egg.

i was thinking of using bubble wrap.
