N = N0e^(ln(2)*t/T) where t is time and T is half life
250 = 600e^(-ln(2)*20/T)
Divide by 600 and take logs
ln(25/60) = -ln((2)*20/T
Rearrange
T = -ln(2)*20/ln(25/60) years. ≈ 15.8 years
-1212(p+2) = -3 -p
-1212p - 2424 = -3 - p add 1212 p to both sides
-2424 = -3 +1211p Add 3 to both sides
-2421 = 1211p divide both sides by 1211
-2421/1211 = p
"Zeroes' are where the function equals zero.....if
x+ 6 = 0
x+8=0
or x+15 = 0 this function will equal zero
SOOOO if x= -6 or -8 or -15 this function will equal zero and these are the 'zeroes' of this function.
A change from 230 to 300 represents a positive change (increase) of 30.434782608695656%
What would the gradient be?
24+3=27
I need help, and could you explain it too?
What are parent functions?
What is the parent function of y=2x?
3(5)(11)y = 11(3)(-15) divide both sides by 3 * 11
5y = -15 divide both sides by 5
y = -3
I believe this is a fake profile
I feel like this contains a secret code to the meaning of life.
220/600 =0.36666..... x 100 =36.67%
Force =[G x Mass(E) x Mass(M)] / Radius^2(between the center of Earth and Moon)
F =~2 x 10^20 newtons.
You'll have to supply a value to 'k' to get a discrete ( 'defined' ) answer from a calculator....
I don't think you will find a shortcut, because the growth is exponential, and thereby unpredictable. I could be wrong!.
Thanks man :)
Maybe this will help :

Do you mean how many pefect cubes it contains???? If that is what you mean, then:
3!5!7! =3,628,800^(1/3) =~153
If you mean by how many pefect cubes is it divisible EVENLY, then I think by these ones only:
1^3, 2^3, 3^3, 4^3, 6^3, 12^3.

Mean = Sum of Values / Number of Values = [ 14+15+ 18+ 17+ 5+11 ] / 6 = 80 / 6 = 40 / 3 ≈ 13.3333.....
You could also use a graph and use the two equations: y=9x and y=7x to find out where those two lines meet or how much money is the same and how many lawns it takes for each to meet.
