The first three steps of completing the square to solve the quadratic equation x^2+4x-6=0 are shown below.

1 answer:

5 0

Take the sqrt of both sides of <span>(x+2)^2=10:

x+2 = plus or minus sqrt(10)

Solve for x: x = -2 plus or minus sqrt(10)

Evaluate x: x = -2 + sqrt(10) AND x = -2 - sqrt(10) (answers)

using data from 2010 and projected to 2020, the population of the United Kingdom (y, in millions) can be approximated by the equ

natita [175]

Answer:

The projected population in 2026 is of 699.3 million.

Step-by-step explanation:

Population:

The population, in x years after 2000, is given by the follwing equation:

$y - 4.55x = 581$

That is:

$y(x) = 4.55x + 581$

What is projected population in 2026?

2026 - 2000 = 26, so this is y(26).

$y(26) = 4.55(26) + 581 = 699.3$

The projected population in 2026 is of 699.3 million.

Find the distance between the points (0,2)and (-5,-9)The answer must be a whole number or a fully simplified radical expression

LiRa [457]

Answer:

d = $\sqrt{146}$

Step-by-step explanation:

$d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d= \sqrt{(-5-0)^2+(-9-2)^2}\\d= \sqrt{(-5)^2+(-11)^2}\\d= \sqrt{25+121}\\d= \sqrt{146}$
