A medicine is decaying at a rate of 5% per hour. If there were initially 1000mg of the medicine, how much is left after 4 hours?
Stolb23 [73]

Answer:

  814.5 mg remain after 4 hours

Step-by-step explanation:

The multiplier of the original quantity is 1 -5% = 0.95 for each passing hour. The amount remaining after x hours is ...

  y = 1000·0.95^x

For x=4, the amount remaining is ...

  y = 1000·0.95^4 = 1000·0.81450625

  y ≈ 814.5 . . . mg remain after 4 hours

The total charge that has entered a circuit element is q(t) = 6 (1 - e-7t) when t ≥ 0 and q(t) = 0 when t < 0. The current in
Bess [88]

Answer:

A=42, B=-7

Step-by-step explanation:

The current function of time is defined as follows:

I(t)=\frac{dq(t)}{dt}

where q(t) is the charge function.

For the given charge function of time q(t)=6\left( 1-e^{-7t}\right) we have the following current function:

I(t)=\frac{d}{dt} \left(6\left( 1-e^{-7t}\right)\right)=42e^{-7t}

In the problem it is proposed that I(t)=Be^{-At}.

Examining the expression of I(t) we obtained by deriving q(t) with the expression proposed by the problem and comparing term by term:

I(t)=Be^{-At}=42e^{-7t}

We conclude that A=-7 and B=42.
