What is the value of 10000a/b from this circle and ellipse problem?
A circle and an ellipse are at larger circle without overlap. For the size of the smaller circle, the area of ellipse has the largest possible area that could fit in the area between smaller and larger circle.
If a= combined area of small circle and ellipse and b= area of larger circle, what is the value of 10000a/b ?

1 JawabanMathematics7 tahun yang laluFind the largest population growth from this following problem?
An observation to the species population from January 2008 to January 2009 gives a following data:
Jan 2008: 3000
April 2008: 1900
July 2008: 1000
Oct 2008: 2050
Jan 2009: 3000
Given: 3000 is maximum and 1000 is minimum.
The observer is predicting that this periodic function at any value of t:
P(t)= 2000+ 1000*cos(2pi*t), 0≤ t ≤1.
For this function, t=0 is the beginning of January 2008, and t=1 is the beginning of January 2009, with the increase rate at every month is 1/12.
