What are the solutions of x2 -2x+2=0

sergejj [24]

Answer: x = 1 ± i

Step-by-step explanation:

Solving the quadratic equation using the quadratic formula:

x = $\frac{-b+\sqrt{b^{2}-4ac } }{2a}$ or $\frac{-b-\sqrt{b^{2}-4ac } }{2a}$

From the question :

a = 1

b = -2

c = 2

substituting inside the formula

X = $\frac{-(-2)+\sqrt{(-2)^{2}-4(1)(2) } }{2(1)}$ or

$\frac{-(-2) - \sqrt{2^{2}-4(1)(2) } }{2(1)}$

x = $\frac{2 + \sqrt{4-8} }{2}$ or $\frac{2 - \sqrt{4-8} }{2}$

x = $\frac{2 + \sqrt{-4} }{2}$ or $\frac{2 - \sqrt{-4} }{2}$

Recall ; $\sqrt{-4}$ can be written as $\sqrt{-1}$ X $\sqrt{4}$ , and $\sqrt{-1}$ = i

Substituting this

x = $\frac{2+2i}{2}$ or $\frac{2-2i}{2}$

simplifying, we have

x = 1 + i or 1 - i

Workland has a population of 10,000, of whom 7,000 work 8 hours a day to produce a total of 224,000 final goods. Laborland has a

kenny6666 [7]

Answer:

Workland has lower productivity but higher real GDP per person than Laborland.

Step-by-step explanation:

Consider the provided information.

Workland has a population of 10,000, of whom 7,000 work 8 hours a day to produce a total of 224,000 final goods.

Productivity = Output / Input

For Workland productivity is:

$\frac{224,000}{7,000 \times 8}=\frac{224,000}{56,000}= 4$

Laborland has a population of 5,000, of whom 3,000 work 7 hours a day to produce a total of 105,000 final goods.

For Laborland, productivity is:

$\frac{105,000 }{3,000\times 7}=\frac{105,000 }{21,000 }= 5$

Thus, Laborland has higher productivity .

To figure real GDP per person, divide output by population:

For Workland,

$\frac{224,000}{10,000}= 22.4$

for Laborland,

$\frac{105,000 }{5,000 }= 21$

Thus, Workland has a higher real GDP per person.

Answer:

The answer is A.

To find speed/rate of change, divide distance by time.

7 mi/ 1 hour= 7 mph

14 mi/2 hour= 7mph

Step-by-step explanation:

Answer: A.7 miles per hour

Step-by-step explanation:

Given: You run 7 miles in one hour and 14 miles in two hours.

We know that .. The rate of change of function= (change in distance)/(change in time)

Therefore, the rate of change of function for the given situation= (14-7)/(2-1)= (7)/(1)

Hence the rate of change of function for the given situation= 7 miles per hour.

What is the probability that the first die will have ""a natural number greater than 1 which can only be divisible by 1 and itse

balandron [24]

Answer:

The probability that the first die will have ""a natural number greater than 1 which can only be divisible by 1 and itself = 0.5

Step-by-step explanation:

A die has 6 faces with the following sample spaces 1, 2, 3, 4, 5 and 6

Then, a natural number greater than 1 which can only be divisible by 1 and itself is the definition of a prime number.

The prime numbers in the sample space are 2, 3 and 5

So, probability of getting a prime number in the sample space, P(prime numbers) = n(prime numbers)/[n(sample space)] = 3/6 = 1/2 = 0.5
