To solve the equation x ^2 - 2x = 3 by the technique of completing the square, you would add 4 to each side of the equation as o

Karolina [17]

Answer:

x = -1

x = 3

Step-by-step explanation:

$\sf x^2 - 2x = 3$

Add 1 to both sides:

$\sf \implies x^2 - 2x+1 = 3+1$

Factor the left side:

$\sf \implies (x-1)^2 = 4$

Square root both sides:

$\sf \implies x-1 = \pm2$

Therefore:

$\sf \implies x-1=-2 \implies x=-1$

$\sf \implies x-1=2 \implies x=3$

Suppose the population of a certain city is 3031 thousand. It is expected to decrease to 2246 thousand in 50 years. Find the per

Kipish [7]

Answer:

The rate at which the population decrease is 59.8 %

Step-by-step explanation:

Given as :

The population of city = 30,31,000

Now The population of city decrease to 22,46,000

The time period in which population decrease is 50 years

Let the percentage rate of decrease = R%

So,

Final population = initial population × $(1-\frac{Rate}{100})^{Time}$

Or, 22,46,000 = 30,31,000 × $(1-\frac{Rate}{100})^{50}$

Or, $\frac{2246000}{3031000}$ = $(1-\frac{Rate}{100})^{50}$

Or, $\frac{2246}{3031}$ = $(1-\frac{Rate}{100})^{50}$

$(\frac{2246}{3031})^{\frac{1}{50}}$ = $( 1-\frac{Rate}{100})$

So , 0.99402 = $( 1-\frac{Rate}{100})$

Or, $\frac{Rate}{100}$ = 1 - 0.99402

So, Rate = $5.98\times 10^{-3}$ × 100

Or, Rate = 0.598 = 59.8 %

Hence The rate at which the population decrease is 59.8 % Answer
