Answer:

Step-by-step explanation:

The unit rate of the 100m race is 2.12... m/s which you get by dividing the 100 meters by the 47 seconds. The unit rate for the 50m race is 2.08... m/s which you get by dividing the 50 meters by the 24 seconds. This means that the record for the 100m race is faster.

What is the answer to 2 1/4 x 3 1/9

vlada-n [284]

2 1/4 times 3 1/9

Make the fractions into decimals

So now it’s 2.25 times 3.11...

Multiply that to get 6.99 but since the 3.11... is a repeated sequence you would round it to 7, which is your answer!

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

xenn [34]

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

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

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

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

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