Question

I don't know how to do this but I know you have to find the growth or decay

Answer 1

Answer:

$\boxed{y=5(1.05)^t\to\:5\% \:rate \:of \:growth}$

$\boxed{f(t)=50(.95)^t\to\:5\% \:rate \:of \:decay}$

$\boxed{g(t)=50(1.5)^t\to\:50\% \:rate \:of \:growth}$

$\boxed{y=5(.5)^t\to\:50\% \:rate \:of \:decay}$

Step-by-step explanation:

We can rewrite the given functions in the form $f(x)=a(100\%+r\%)^x$ to determine the rate of growth or $f(x)=a(100\%-r\%)^x$ to determine the rate of decay

$y=5(1.05)^t=5(100\%+5\%)^t\to\:5\% \:rate \:of \:growth$

$f(t)=50(.95)^t=50(100\%-5\%)^t\to\:5\% \:rate \:of \:decay$

$g(t)=50(1.5)^t=50(100\%+50\%)^t\to\:50\% \:rate \:of \:growth$

$y=5(.5)^t=5(100\%-50\%)^t\to\:50\% \:rate \:of \:decay$
