a) On January 1 2000, the park estimated that they had 500 deer on their land. Two years later, they estimated that there were 550 deer on the land. Assume that the number of deer was changing exponentially,...
For my maths assignment, i had to do an experiment using a pendulum and measuring the amplitude of every 10 swings up to the 80th swing. One of the questions is find the ratio between consecutive...
a radioactive substance decays according to the equation A(t)=A0(0.1)0.073, where t is in years and A0+1 is the original amount of the substance. How long will it take until there is only...
The pH scale is defined as pH= -log [H+], where [H+] is the concentration of hydronium ions, measured in mole per litre. If pH > 7, the solution is basic. If pH...
A radioactive substance decays according to the equation A(t)= A0().1)0.073t, where t is in years and A0=1 is the original amount of the substance. How long will it take until there is only 10% of...

compare a situation that you could use an exponential function to represent, to situations for which you would use another function .
Y=10-9^(x-3)
y=2x-4 y=2x+4 I'm confused by one being exponents but one isn't. How do I graph these? I try different x values like -1 and -2 but they don't appear similar...
The graph of y = f(x) = bx, where b > 1, is translated such that the equation of the new graph is expressed as y + 2 = f(x + 4). The domain of the new function is
The sales, S, of a product have declined in recent years. 1.8 million were sold in 2009 but only 1.2 million sold in 2012. Assume the sales are decreasing according to the exponential model S(t)=Soe^kt A...
The temperature, T ( Degree C), of a quenched steel plate at time t is given by T = f(t) = 10 + 85/1 + e^ (tâ60)/10 where 0 â¤ t â¤ 100 measured in seconds. (a) We want to know...
