Here is the explanation I wrote on the paper. ASK QUESTIONS IN THE COMMENTS! I absolutely LOVE answering questions, and you understanding what I mean in my answer means the world to me.
Peperoni and sausage had the same ratios because peperoni is 5/25 and 12+5+3=20 and 25-20=5 which is the sausage.
Y=Ф + 8/(ФcosФ) ==> note that
dy/dФ = 1 - 8/[(ФcosФ)]² x (-8sinФ) ==> dy/dФ = 1+[(64sinФ)/Фcos²Ф]
==> dy/dФ = 1+ 64tanФ/Ф or dy/dФ = (Ф+tanФ)/Ф
First calculate the radius = 1/2 the diameter = [sqrt sqr160(4-0)^2 + (-14-(-2))^2] / 2
= (sqrt 160 ) / 2 so r^2 = 160 /4 = 40
center = midpoint of the diameter = (-14-2)/ 2 , (4+0)/2 = (-8, 2)
so required equation is (x + 8)^2 + (y - 2)^2 = 40
The answer to this is 2. Ten only has two factors, 5 and 2, and 2 can be decided evenly amongst them all.
