Constants are anything that is not a variable. A variable is a letter. So think about it... What would be the constants? What is not a letter? TIP: Make sure you include - sign!_
I hope this helps you
DF^2+DC^2=FC^2
DF^2+15^2=39^2
DF^2=39^2-15^2
DF^2=24.54
DF=36
The formula is
P=Ae^rt
P ?
A 430
R 0.9/100=0.009
T time 2010-2000=10 years
E constant
P=430×e^(0.009×10)
p=470
