Answer:
C>-1/4
Step-by-step explanation:
Two have intersection it must be:
2x+c= x^2+3x, i.e,
x^2+x-c=0
Solution of its equation is:
If we we want two solution we must have that:
1+4c>0
So c>-1/4.
All you have to do is divide the numerator by the denominator and then multiply that result with 100 like so:
(Numerator/Denominator)*100
When you enter 8/40 into the above formula, you get (8/40)*100 which calculates to:
20%
A= 50.27 because the formula is pi times radius squared
C= 24.13 because the formula is 2 times pi times radius
Y = x + 2 is closest to what I believe is the solution.
If the club begins with 2 members, then +2 MUST appear in the formula.
If the club adds 2 members every week, then the total number of members would be
f(x) = y = 2 + 2(x-1), where x is the number of weeks.
Test this: If x = 1, then y = 2+2(1-1) = 2 + 0 = 2. This is correct. The club began with 2 members in week 1
