an exponential equation will look like
y = a(b)ˣ
now, the tale-tell guy is the "b" component, or growth/decay factor.
if "b" is less than 1, is decay, if "b" is greater than 1, is growth.
in this case b = 0.68, that's less than 1, so decay.
Answer:
y=2*0.68^x = exponential decay
Step-by-step explanation:
Answer: The surface area is 65 cm.
.50 = .08m divide both sides by .08
.50 /.08 = m = 6.25 minutes
