Answer:
Step-by-step explanation:
If the length of one side of A is a, then B is twice that of A, so the length of one side is 2a. The circumference of A is 4a, B is 8a
B : A = 8a : 4a = 2 : 1
Solve by Substitution

Answer:
41 degrees F
Step-by-step explanation:
(Ah, calculus...)
In this case, is 0 degrees F and is 140 degrees F. k = -0.0815 and t = 15. Plug all these values into the equation:
41.229 ≈ 41
So, the answer is 41 degrees F.

Answer: 8
Step-by-step explanation:
Here we have the equation of a vertical ellipse (this means the major axis is in the y-axis) with a center in the form:
Where is the semimajor axis and is the semiminor axis, being the major axis .
So, if we have this given equation:
Then:
Hence:
This is the major axis of the ellipse
