Answer:

x^2+2x+2

Step-by-step explanation:

to find b in the equation :

b^2<4ac when having two complex roots

the required equation is x2 - Sx + P = 0

the sum of the roots :-1-i+-1-i=-2

the product=2

so the equation: x^2-(-2)x+2

x^2+2x+2

Answer:

Step-by-step explanation:

Formula for finding a quadratic equation when its roots are given is

x² - ( sum of roots)x + product of roots=0

The roots are

- 1 + i

- 1 - i

Sum of roots is = - 1 + i - 1 - i = -2

Product of roots is = ( -1 + i)(- 1 - i)

= 1 + 1 = 2

So the quadratic equation is

x² - (-2)x + 2 = 0

Hope this helps you

First let us convert 0.01 into fraction:

$\frac{y^{2}}{100} -\frac{1}{4}$

Now we convert 100 and 4 into perfect squares as follows:

$(\frac{y}{10})^{2}-(\frac{1}{2})^{2}$

Now we use the property of :

$x^{2} -y^{2} =(x+y)(x-y)$

$(\frac{y}{10} +\frac{1}{2} ) (\frac{y}{10} -\frac{1}{2} )$

Answer: y = 6

Step-by-step explanation:

A square's area can be done by using s^2, where s is y in this case. Because there are 5 squares, the area of the figure is 5y^2. Because the area is also 180cm, 5y^2=180.

Then divide both sides of the equation by 5 to get y^2 = 36. Then square root both sides of the equation to get y = 6.

How many hours would you have to ride your bike at 10 mi/h to burn 550 calories? (Per Minute)

vesna_86 [32]

Answer:

The time spend to burn energy is 3300 minutes .

Step-by-step explanation:

Given as :

The speed at which the bike ride = 10 miles per hours

The energy burn while riding = 550 calories

Let The time spend to burn energy = t minutes

So, According to question

Time spend = $\dfrac{\textrm Energy burn}{\textrm rate of ride}$

i.e t = $\dfrac{550}{10}$ hours

∴ t = 55 hours

So, in minutes

The time spend

1 hours = 60 min

∴ 55 hours = 60 × 55 = 3300 minutes

So, The spend to burn energy = t = 3300 minutes

Hence The time spend to burn energy is 3300 minutes . Answer
