A radioactive isotope decays at the rate indicated by the exponential function ,where 't' is the time in year and A(t) is the amount of the isotope, in grams, remaining. How long will it take for the isotope to be reduced to half of its original amount?

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

its an acute right triangle
