When was the solar nebula?

4.6 billion years ago4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. How long did the solar nebula last? And the authors make the case that the near-zero magnetic field at this time

What is F x and G x?

The function g (x) is called an inner function and the function f (x) is called an outer function. Do F x and G x mean the same thing? Yes, they are the same. You just have to factor the (x2 – 1) in the numerator of f(x) and cancel out the (x + 1).

How do you find the median of a triangle Khan Academy?

Now a median of the triangle– and we’ll see a triangle has three of them– is just a line that connects a vertex of the triangle with the midpoint of the opposite side. So the opposite side’s midpoint looks right about there. This length is equal to that length. And so this is a median.

Is the Kuiper belt the asteroid belt?

The Kuiper belt (/ˈkaɪpər/) is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive. What’s the difference between asteroid

Are functions functors?

A function assigns to every element of a set X an element of a set Y. A functor assigns to every object of a category C an object of a category D and also assigns to every morphism in C a morphism in D in a way compatible with sources, targets, and composition. Is a

How do you identify dimensions?

To identify dimensions, you perform the following steps: Use the grain definition to locate possible dimensions. List all of the dimensions that are associated with this grain. Define the level of detail to include in that dimension. Create surrogate keys for the primary keys of the dimensions. How do you identify dimensions and facts? If

Why is SSA not a congruence shortcut?

Four shortcuts allow students to know two triangles must be congruent: SSS, SAS, ASA, and AAS. Knowing only side-side-angle (SSA) does not work because the unknown side could be located in two different places. Why is there no SSA congruence theorem? The SSA congruence rule is not possible since the sides could be located in

What is initial point math?

The initial point establishes a local geographic coordinate system for the surveys that refer to that point. An initial point is defined by the intersection of a principal meridian and a base line. What does initial point mean? 1. The first point at which a moving target is located on a plotting board. 2. A

How did Dennis Tito make his money?

In 1972, he founded the Wilshire Associates, a leading provider of investment management, consulting and technology services in Santa Monica, California. Tito serves an international clientele representing assets of $71 billion. How much did Dennis Tito pay to go to space? $20 million Businessman Dennis Tito paid $20 million to fly with the Russians to

How can we model relationships between quantities?

A linear relationship between two quantities will produce a graph of a straight line. The line represents every possible solution for the range of the function. In order to create the line, we use the function equation and evaluate the range, or output, values based upon several of the domain, or input, values. How can
