The mass of a radioactive substance follows a continuous exponential decay model, with a decay rate parameter of per day. Find t
jasenka [17]

Answer:

t = ln(0.5)/-r

Step-by-step explanation:

The decay rate parameter is missing. I will assume a value of 4% per day.

The exponential decay is modeled by the following equation:

A = A0*e^(-r*t)

where A is the mass after t time (in days), A0 is the initial mass and r is the rate (as a decimal).

At half-life A = A0/2, then:

A0/2 = A0*e^(-0.04*t)

0.5 = e^(-0.04*t)

ln(0.5) = -0.04*t

t = ln(0.5)/-0.04

t = 17.33 days

In general the half-life time is:

t = ln(0.5)/-r

HELP,ME PLEASE IM RLLY CONFUSED ON THIS ONE,THANKS IN ADVANCED

We can notice that : Line Passes through the Points  (1 , 2) and (4 , -4)

Let us find the slope of the line in order to write the Equation of the Line.

Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

\heartsuit\;Slope(m) = \frac{y_1 - y_2}{x_1 - x_2}

Points are (1 , 2) and (4 , -4)

here x₁ = 1 and x₂ = 4 and y₁ = 2 and y₂ = -4

\heartsuit\;Slope(m) = \frac{2 + 4}{1 - 4} = \frac{6}{-3} = -2

Equation of the Line passing through (1 , 2) and having slope -2 is :

⇒ y - 2 = -2(x - 1)

⇒ y = -2x + 2 + 2

⇒ y = -2x + 4
