) If the half-life of 238Pu is 87.7 yr, write a function of the form =QtQ0e−kt to model the quantity Qt of 238Pu left after t years. Round the value of k to five decimal places. Do not round intermediate calculations.

0.079

Step-by-step explanation:

According to the given situation, the calculation of the value of k is presented as follows:

now,

After solving the above equation we will get the value of k.

= 0.079

Therefore for determining the value of k we simply solve the above equation i.e. by considering all the information mentioned in the question

i would go with the first one

step-by-step explanation:

hope this

it has the same slope and a different y-intercept

hope this : )
