Answer:
52.4
Step-by-step explanation:
% change = 100 x final initial/initial
9 because most of the triangle have to sides of the same sizes
Step-by-step explanation: What they mean is if you were to say put all that data onto a graph, any kind of graph. What graph would you chose, and why? How you would work through this kind of problem, or at least how I would approach it weight out the pros and cons of each graph, or put some data on different graphs and see what works best. On the contrary if you have a rough idea of how each graph would look like you would just chose the one you think conveys the information best. I think they're is a best answer, but no wrong answer, you can make an argument for most graphs if you try, so just chose the one you think is best, and write your reasoning.
Answer:
<h2>The equation represents an ellipse with an eccentricity of 0.7.</h2>
Step-by-step explanation:
The given equation is
![r=\frac{2.1}{1+0.7cos\theta}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B2.1%7D%7B1%2B0.7cos%5Ctheta%7D)
This equations represents a conic section in polar form, where the coefficient of the cosine function is the eccentricity of the conic section.
So, in this case, the eccentricity is
, which indicates that the equation belong to an ellipse, because the eccentricy of ellipses are between 0 and 1.
Therefore, the equation represents an ellipse with an eccentricity of 0.7.
