if an alien at this moment would be looking at earth through a telescope from 100,000 light years away, what would it see?

In theory, yes. Light that left the earth 65 million years ago is now 65 million light years away, and an alien with a big enough telescope pointed directly at the earth might be able to see dinosaurs. Practically, such a telescope would be impossibly huge.

Hmm, rather unusual question. I think that if an alien were looking at Earth 100,000 light years away, I don't think it would be able to see Earth! But if it could, it would see a planet filled with life, buildings, water and land.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
