Answer:
According to the nebular theory, the planets formed from a process called <u>accretion</u>.
Explanation:
The nebular theory is a theory that explains the formation of solar systems. After the formation and growth of the proto-star, the gases and dust in the nebula form a disk and spiral quickly around its center under the influence of its gravitation. This long and destructive process ends with the formation of planets, characteristics of which depend on their distance from the star. The term from astrophysics referring to this way of planet formation is <em>accretion</em>. Planets are not only astronomical objects created by accretion processes but galaxies and stars as well.

Answer: B (130)
Explanation:
A trapezoidal Riemann sum can be found by multiplying the width (the change in x) of each sub interval by the average of the y values of the two points at either end of the section and then adding up all of the sun intervals. Therefore, the trapezoidal approximation would equal 0.5(40) + 1.5(50) + 1(35) to get the answer of 130.
I think the answer is B im sure correct me if im wrong.
