Use the approximate half-life formula for the case described below. Discuss whether the formula is valid for the case described. Urban encroachment is causing the area of a forest to decline at the rate of 8% per year. What is the half-life of the forest? What fraction of the forest will remain in 30 years?

What is the half-life of the forest?

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
