Answer:
<h2>The equation represents an ellipse with an eccentricity of 0.7.</h2>
Step-by-step explanation:
The given equation is
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.
45% is 45/100, divide that by 5 and you get 9/20

So given the values on the number line, AB and BC, adding them together will get the length of AC. If AB equals
and BC equals
, the value of AC should be
. Since you are given the length of AC,
, you can create an equation to solve for x. This equation would be
. Isolating the x on the left (or right hand side) gets the value of x to be 19. The same thing goes for the 2nd question.
Answer:
Step-by-step explanation:
When we graph the points, the polygon is a quadrilateral with opposite parallel sides. The type of polygon formed by these points is a parallelogram.
