Growth and Decay Rates and Factors
Is this growth or decay?
y=3(2^x)
What is growth
See Board.... What is the equation?
What is f(x)=4^(x-1)
y=3(4^x)
HA? Growth or Decay? Y-int? Increasing/Decreasing (AROC too)?
See the board
Solve: 10^5x=100
x=2/5
Which is better? An account that pays 10% compounded biannually? Or an account that pays 9.3% compounded continously? And why?
What is an account that pays 10% compounded biannually because your growth rate is higher, which means you will get more money back.
Is this growth or decay?
y=100(1/4^(x-3))
What is decay
See Board..... What is the equation?
What is f(x)=1/2(2^(x+2))
y=2(1/2)^(x+3)
HA? Growth or Decay? Y-int? Increasing/Decreasing (AROC too)?

A radioactive substance decays at a continuously compounded rate of 12% per year and 25 mg is there initially.
a)write an equation for F(y), the amount of radioactive substance remaining y years after the initial year.
b)When will the amount of radioactive substance be below 7 mg?
a) F(y)=25e^-.12y
b)10.61 years
