For what real numbers x is the value of x2 – 6x + 9 negative
Nutka1998 [239]
A real numbers are numbers that can be found on a number line, they include both rational and irrational numbers.
We can first solve the equation;
x² - 6x + 9 =0, using completing square method;
 x²- 6x + (-3)² = -9 + (-3)²
     (x-3)² = 0
       x = 3
therefore,  both values of x are 3, thus the expression has no real number x is negative.

Country A has a growth rate of 4.9​% per year. The population is currently 4 comma 151​,000, and the land area of Country A is 1
kvv77 [185]

Answer:

There will be one person on 1 square yard of land after 1,892,147.588 years.

Step-by-step explanation:

Continuous exponential growth formula:

P(t)=Pe^{rt}

P(t)= Population after t years.

P= Initial population

r=rate of growth.

t= time in year

Given that,

Growth rate of country A (r)= 4.9% per year=0.049 per year.

Initial population (P)= 151,000.

Land area of country area= 14,000,000,000 square yards.

There will be one person on one  square yard of land.

So, there will be 14,000,000,000  person for 14,000,000,000 square yard of land in country A.

P(t)=14,000,000,000 person

\therefore 14,000,000,000= 151,000 e^{0.049t}

\Rightarrow e^{0.049t}=\frac{ 14,000,000,000}{ 151,000}

Taking ln both sides

\Rightarrow ln|e^{0.049t}|=ln|\frac{ 14,000,000,000}{ 151,000}|

\Rightarrow {0.049t}=ln|\frac{ 14,000,000,000}{ 151,000}|

\Rightarrow t}=\frac{ln|\frac{ 14,000,000,000}{ 151,000}|}{0.049}

\Rightarrow t}=1,892,147.588 years

There will be one person for every square yard of land after 1,892,147.588 years.
