Can i get some been trying to figure this question on but don’t seem to get it.

Step-by-step explanation:

If you square the binomial (x -a), you get ...

  (x -a)² = x² -2ax +a²

Comparing this to your equation, you find that ...

  -2a = -5/3 . . . . . . the x-coefficient

  a = (1/2)(5/3) = 5/6

So, the number in the right box is 5/6, and the number in the left box is its square, (5/6)² = 25/36.

Filling these in, the equation reads:

  x² -5/3x +25/36 = (x -5/6)²

__

That is, the constant in the squared binomial is half the x-coefficient.

step-by-step explanation:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
