Find the complex zeros of the following polynomial function.

GalinKa [24]

Answer:

$x=\frac{-1\pm\sqrt{3}i}{2}$

Step-by-step explanation:

$f(x)=x^3-1$

$0=x^3-1$

$0=(x^2+2x+1)(x-1)$

$x-1=0$

$x=1$ <-- Real Solution

$x^2+x+1=0$

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

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

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

$x=\frac{-1\pm\sqrt{1-4}}{2}$

$x=\frac{-1\pm\sqrt{-3}}{2}$

$x=\frac{-1\pm\sqrt{3}i}{2}$ <-- Complex Solutions

Prav is converting £257 into $. He knows that £1 = €1.11 and €1 = $1.22. How many $ will Prav get? Give your answer to 2 dp.

Ostrovityanka [42]

Answer:

$348.03

Step-by-step explanation:

£257 = €1.11 * 257

£257 = €285.27

€285.27 = $1.22 * 285.27

€285.27 = $348.0294

Round to 2 dp, $348.03

Please I need help!!!

Valentin [98]

Answer:

Solution given:

for second

we have

f(x)=x²-9x-36

let

y=x²-9x-36

when

x=0

y=-36

when

y=0

0=x²-9x-36

x²-12x+3x-36=0

x(x-12)+3(x-12)=0

(x-12)(x+3)=0

either

x=12

x=-3

So,

x and y intercepts are (-3,0)(12,0) and 0,-36)
