Lodine-131 is a very useful radioactive isotope that is used to locate and treat cancerous tumors in the body and has a half lif
Dvinal [7]

Using an exponential function, it is found that 4 mg of the substance would still be left after 32 days.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem, considering that the initial amount if of 64 mg, and we are working with half-lifes, the equation is given by:

A(t) = 64(0.5)^t

32 days is 32/8 = 4 half-lifes, hence the amount remaining in mg is given by:

A(4) = 64(0.5)^4 = 4

an aeroplane is flying with a help of 300 km per hour who much distance will it cover in 160 minute ​
uysha [10]

Answer:

800 km

Step-by-step explanation:

Does the plane have a speed of it's own?  I don't see it, so will assume the plane is simply travelling at 300 km/h.

(300 km/hr)*(1 hr/60 min) = 5 km/min

(5 km/min)*(160 min) = 800 km in 160 minutes
