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.
Answer: hello your question is incomplete attached below is the complete question
answer :
a) ( option D )
b) A = 1/2 (6)(3) ( option B )
c) Area of shaded region = 9
Step-by-step explanation:
<u>a) Using integration with respect to x </u>
Area = ( note a = 10 )
= y^2/2 - 4y |⁷₄ + 10y - y^2/2 |¹⁰₇
= 33/2 - 12 + 30 - 51/2 = 9
hence the best integral from the options attached is option D
= [ 10x - x^2 /2 - x^2/2 - 9x ] ³₀
= 30 - 9/2 - 9/2 - 12 = 9
<u>b) Using Geometry </u>
Area = 1/2 * base * height
= 1/2 * 6 * 3
= 9
