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,

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
