Exponential growth: the world population was 2010 about 7 billions; the yearly population growth is just below 2%. assuming r=2% being stable:
how much time did elapse since the people were only 3.5 billion?
[type the nummerical value rounded to full years ]

time is 24.66 years

Step-by-step explanation:

Given data

population A = 7 billion

rate = 2% = 0.02

population P = 3.5 billion

to find out

time

solution

we will apply here formula that is

A = P

here put all value

7 = 3.5

take ln both side

ln (7/3.5) = ln

0.02t = ln2

t = ln2 / 0.02

t = 24.66

so time is 24.66 years

linear pair postulates

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
