Every time I do this on my calculator I get an error. Can anyone help me out?
Sorry, I'll just type it out.
The function D(h)=7e^(-0.4h) can be used to determine the milligrams D of a certain drug in a patient's bloodstream h hours after the drug has been given. How many milligrams (to two decimals) will be present after 11 hours.
Substitute the 11 for h; therefore, the equation will now look like this
Can you solve it now?
If it is a calculator issue .. I would do it this way
whatever the command is for e
for example on my calculator it is 2nd e
so I would do something like this
2nd e ^ -4.4 enter * 7 enter
