The function A = A 0 e -0.0077x models the amount in pounds of a particular radioactive material stored in a concrete vault, whe
AysviL [449]

Answer:

After 80 years 432 pounds of radioactive element will be remaining.

Step-by-step explanation:

A function A_{t}=A_{0}e^{-0.0077x} models the amount of a radioactive material.

Here x = number of years taken for decay.

If A_{t}=432 pound and A_{0}=800 pound, then we have to calculate the time for decay.

A_{t}=A_{0}e^{-0.0077x}

432=800e^{-0.0077x}

e^{-0.0077x}=\frac{432}{800}

Take log on both the sides of the equation

ln(e^{-0.0077x})=ln(\frac{432}{800} )

-0.0077x = ln(0.54)

-0.0077x = -0.616186

x = \frac{0.616186}{0.0077}

x = 80.02 years

Therefore, After 80 years 432 pounds of radioactive element will be remaining.

VMariaS [17]

Answer:

Yes the ordered dose of 200 mg/d lies within the recommended range of 75 mg/d to 375 mg/d

Step-by-step explanation:

Given:

Ordered dose of Anadrol-50 (oxymetholone) = 200 mg per day

Recommended range = 1-5 mg/kg/d

Weight of the patient = 75 kg

Now,

For the patient weighing 75 kg, the recommended dose will be

Minimum dose will be

= Minimum value of Recommended range × Weight of the patient

= 1 mg/kg/d × 75 kg

= 75 mg/d

and,

the Maximum dose will be

= Maximum value of Recommended range × Weight of the patient

= 5 mg/kg/d × 75 kg

= 375 mg/d

Yes the ordered dose of 200 mg/d lies within the recommended range of 75 mg/d to 375 mg/d
