Answer:
where is the thing to answer
Answer:
It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.
Step-by-step explanation:
An adult takes 400 mg of ibuprofen. Two hours later, there is 201.6 mg of
ibuprofen left in the persons system
This means that in 2 hours time
400- 201.6= 198.4 mg was used up.
We need only 25 mg in the system
so 400- 25= 375 mg time is needed
time mg
2 hour 198.4
x 375
Using the cross product rule
x= 375*2/198.4
x= 3.780 hrs
Which means 3 hours and (0.78* 60)= 46.8 minutes.
It will take 3 hours 46 minutes and 8 seconds to use 375 mg of ibrufen.
Interest = p times R times T
C.
No value of x has two values of y, thus it is a one-to-one function.
Answer: $11,820
Step-by-step explanation:
The formula to calculate the compound amount after x years is given by :-
, where r is the rate of interest.
Given: The accumulated value A= $25000
The rate of interest r= 4.25%=0.0425
Let P be the present value invested in the account.
Now,according to the question,we have
![25000=P(1+0.0425)^{18}\\\\\Rightarrow\ 25000=P(2.11528624641)\\\\\Rightarrow\ P=\frac{25000}{2.11528624641}\\\\\Rightarrow\ P=11818.7314092\approx\$11820......[\text{to the nearest tens}]](https://tex.z-dn.net/?f=25000%3DP%281%2B0.0425%29%5E%7B18%7D%5C%5C%5C%5C%5CRightarrow%5C%2025000%3DP%282.11528624641%29%5C%5C%5C%5C%5CRightarrow%5C%20P%3D%5Cfrac%7B25000%7D%7B2.11528624641%7D%5C%5C%5C%5C%5CRightarrow%5C%20P%3D11818.7314092%5Capprox%5C%2411820......%5B%5Ctext%7Bto%20the%20nearest%20tens%7D%5D)
Hence, the amount of money presently in the account =$11,820
