$f(x) = 0 \\\\\implies x^3-13x^2+59x -87 =0\\\\\implies x^3 -3x^2 -10x^2 +30x +29x - 87=0\\\\\implies x^2(x-3) - 10x(x-3) + 29(x-3) =0\\\\\implies (x-3)(x^2 -10x +29) =0\\\\\implies x - 3 = 0 ~~ \text{or}~~x^2 -10x +29 = 0\\\\\implies x =3~~ \text{ or} ~~ x = \dfrac{-(-10) \pm \sqrt{(-10)^2 -4 \cdot 1 \cdot 29}}{2(1)}\\\\\implies x =3~~ \text{ or} ~~ x = \dfrac{10\pm \sqrt{-16}}{2}\\\\\implies x =3~~ \text{ or} ~~ x = \dfrac{10\pm 4i }{2}\\$

$\\\implies x =3~~ \text{ or} ~~ x =5 \pm 2i\\\\\text{Hence the complex roots are,}~ 5- 2i ~~ \text{and} ~~5 + 2i$

A battery was charged. When the changing began, it was 23 percent full. After 30 minutes of charging, the battery was 89 percent

Aleks04 [339]

Before it charged, the battery was at 23%. In half and hour, it went to 89%. So, it rose 89-23, or 66% in half an hour. Now that we know how much it rose and that there are 30 mins in half an hour, we have to divide 66% by 30 to figure out the answer.

66/30 is 2.2.

So, the battery rose at 2.2% per minute.

Hope this helps!

Look at this triangle work out length BC

Andreas93 [3]

Answer:

The length of BC is √105 cm or 10.2 cm.

Step-by-step explanation:

You have to apply Pythagoras Theorem, c² = a² + b² where c represents hypotenuse, a and b are the sides :

${c}^{2} = { a}^{2} + {b}^{2}$
