Q(t)=qoe^-kt may be used to model radioactive decay. q representing the quantity remaining after t years, k is the decay constant 0.00011. what is the half-life in years?

Step-by-step explanation:

Given that a substance decays exponentially at the rate of k times the population present.

k = 0.00011

Q0 is the initial population, and Q(t) is the population at time t.

Relationship is given by

Let after t years there is half life

Then 1/2 =

Take log

t = -ln2 /(-0.00011) = 6301.34 years

answer: the answer is 127 degrees

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
