Are main sequence stars hotter or cooler than the sun?
They are both hotter and cooler because the main sequence contains a lot of stars including the Sun. The main sequence is a region on a Hertzsprung-Russell diagram which plots stars on a graph of brightness against surface temperature. Each star is a point on the diagram because it has one value of brightness and one of temperature. All the main-sequence stars lie on or near a line drawn from top left to lower right. The Sun is about halfway along the main sequence.
What does main sequence mean?
The Hertzsprung-Russell diagram is a scatter graph of stars in which a star's luminosity (brightness) is plotted against its colour (temperature). Stars are not distributed all over this chart. A majority of stars lie on or near the diagonal which goes from top left (hot and bright) to bottom left (cooler and less bright). These are the main sequence stars.There are also white dwarfs which are below the main sequence whereas stars which are giants and super giants lie in the region above the main sequence.
What is the main sequence phase of a star?
The main sequence phase means that, if you plot an H-R (Hertzsprung-Russel) diagram, it is in the so-called "main sequence", the area in the graph where you find the majority of stars. Those are the stars that currently fuse hydrogen into helium.
According to the graph the sun is classified as a?
The Sun is classified as a star with a spectral classification of G2V. The Sun is about 4.567 billion years old.
What kind of graph graph that shows the relationship of a star's temperature to its absolute magnitude?
That is called the HR diagram (Hertzsprung Russell) and the temperature is along the horizontal axis while the vertical axis is the star's absolute magnitude. Each star has a fixed point in this diagram, and it shows that most stars belong in a broad band on the left called the Main Sequence.
Why is the sun called a main sequence star?
The main sequence is a line on a Hertzsprung-Russell diagram, on which every star is placed on a graph of absolute magnitude against surface temperature. Each star produces a dot on the diagram, and all the main sequence stars fall roughly on a straight line. On the main sequence the hot bright stars are on the top left and the cooler dimmer red stars are on the lower right. The Sun is just above halfway up.
Are main sequence stars hotter or cooler than the sun?
They are both hotter and cooler because the main sequence contains a lot of stars including the Sun. The main sequence is a region on a Hertzsprung-Russell diagram which plots stars on a graph of brightness against surface temperature. Each star is a point on the diagram because it has one value of brightness and one of temperature. All the main-sequence stars lie on or near a line drawn from top left to lower right. The Sun is about halfway along the main sequence.
What is a graph where arrows appear on the edges called?
It is a directed graph.
What type of graph represents the sequence given by the explicit formula an 5 n - 12?
-7
What type of graph represents the sequence given by an 16 n - 1?
The sequence represented by the formula (16n - 1) is a linear sequence, where (n) is a positive integer. A graph of this sequence would be a straight line, with the x-axis representing (n) and the y-axis representing the value of the sequence. The line would have a slope of 16 and intersect the y-axis at -1. Thus, the graph shows a linear relationship between (n) and the sequence values.
What does constant speed appear as on a V-t graph?
On a graph of velocity and time, a constant speed would appear as a straight horizontal line.
Where were the point of underutilization appear on a production possibilities graph?
no
How do you find whether a given degree form a graph or not?
To determine if a given degree sequence can form a graph, you can use the Havel-Hakimi algorithm or the Erdős-Gallai theorem. The Havel-Hakimi algorithm involves repeatedly removing the largest degree from the sequence, subtracting one from the next largest degrees, and checking if the sequence remains valid (i.e., non-negative). If you can reduce the sequence to all zeros, it represents a valid graph; otherwise, it does not.

Which of the following is the graph of an arithmetic sequence whose first term is 2 and whose common difference is 0.5?
Since there are no graphs following, the answer is none of them.
Is a graph considered a table?
No. Often a graph will be of figures from a table and often the table will appear with it, but they are different. Many graphs do not relate to tables at all.
What is the graph of an arithmetic sequence whose first term is 1 and whose common difference is 0.5?
The graph will be a set of disjoint points with coordinates [n, 0.5*(1+n)]
