Please help with the question,

castortr0y [4]

The correct answer is x^2-2x+2=0

The explanation is shown below:

1. To solve the problem shown in the figure above, you must apply the following proccedure:

2. You have that the roots of the quadratic equation shown in the figure attached in the problem are:

x=-1±i

3. Then, you know the quadratic formula to solve quadratic equations, which is:

(-b±√(b^2-4ac))/2a

4. You can see in the figure that a=1 and c=2; then, by analizing this, you can conclude that the coefficient b is:

b=-2

5. Therefore, you can conclude tha the quadratic equation is:

x^2-2x+2=0

6. If you want to verify it, apply the quadratic formula to the quadratic equation shown above and you will obtain the roots shown in the figure.

A cyclist rides 225 m each minute.About how long does it take to ride 15km? Show all fo your work

Elan Coil [88]

Speed = 225 metres per minute

Distance = 15 km = 15,000 metres

---------------------------------------------------

s=d/t

ts=d

Therefore: t=d/s

--------------------------------------------------

Time = Distance / Speed

Time = (15,000 metres) / (225 metres per minute)

--------------------------------------------------

Let's work it out:

$Time=\frac { 15,000\quad metres }{ \frac { 225\quad metres }{ 1\quad minute\left( s \right) } } \\ \\ =\frac { 15,000\quad metres }{ 1 } \cdot \frac { 1\quad minute\left( s \right) }{ 225\quad metres } \\ \\ =\frac { 15,000 }{ 225 } minutes$

$\\ \\ =\frac { 200 }{ 3 } minutes\\ \\ \frac { 200 }{ 3 } minutes\quad =\quad 66\quad minutes,\quad 40\quad seconds$
