Answer:HMMMMM I don’t really know
Step-by-step explanation:
update: 405.52 mg isn't the correct answer
Okay so the right answer is 24.66 because the text says 100 milligrams of medicine which leaves the bloodstream at 14% per hour. so the rate 14% is going to be negative
A(t) = Ie^rt
A(10) = 100e^-0.14(10)
A(10) =24.66
Answer:
Tiffany has 13 dimes and 4 nickels.
Step-by-step explanation:
To solve this problem, you will need to write a systems of equations, n will be the number of nickels and d will be the number of dimes.
n+d=17 This means that the number of nickels plus the number of dimes is equal to 17.
5n+10d=150, This means that for each nickel, there is 5 cents and for each dime, there is 10 cents. The equation is equal to 150 cent because the coins are worth 150 cents.
Next, solve the system:
n+d=17
5n+10d=150 First simplify the second equation by dividing it all by 5.
n+d=17
n+2d=30, Next, isolate n to use substitution on the system.
n=17-d
n=30-2d, Substitute n to solve for d
17-d=30-2d, Solve for d
d=13, this means that there are 13 dimes, plug in the d value in either of the equations to find n.
n+(13)=17
n=4, There are 4 nickles
Answer:
$27000
Step-by-step explanation:
11% of 60000 is 3300 per year. You need the value for five years so multiply 3300 * 5 to get 33000. 33000 is the total depreciation of the five years. Then subtract 33000 from 60000 to get 27000.
The inverse function of the above function is f(x) = 
You can find the inverse of any function by switching the f(x) and x terms. Once you have done that, solve for the new f(x). Finally, what you'll have remaining is the inverse function. The work is done for you below:
f(x) = 
----> Switch the x and f(x)
x = 
---> square both sides
= 2f(x) + 2 ---> subtract 2 from both sides
- 2 = 2f(x) ----> divide both sides by 2
= f(x) ----> switch the order for formatting sake.
f(x) =
