The function q(t)=qoe^kt may be used to model radioactive decay. q representing the quantity remaining after t years; k is the decay constant. what is the decay constant for plutonium -240 if it's half-life is 6,300 years?

A. -[ln(0.5)/6,300]

Step-by-step explanation:

Done on apex, it is correct.

Answer : The value of decay constant is,

Explanation :

Half-life of plutonium-240 = 6300 years

The expression used to calculate the rate constant is:

where,

k = decay constant

= half-life

Now put all the given values in the above formula, we get:

Therefore, the value of decay constant is,

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
