Find all real and complex zeros of p(x)=x^3-x^2-4x-6

yuradex [85]

Answer:

x = 3 , -1 + $\sqrt{-1}$ , -1 - $\sqrt{-1}$

Step-by-step explanation:

⇒ $p(x)=x^{3} -x^{2} -4x-6$

⇒ $p(x)=(x-3)(x^{2} +2x+2)$

now, for zeros of $(x^{2} +2x+2)$ ,

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

⇒ x = $\frac{-2}{2}$ ± $\frac{\sqrt{2^{2}-4(2) } }{2}$

⇒ x = -1 ± $\sqrt{-1}$

hence, all the roots are,

x = 3, -1 + $\sqrt{-1}$ , -1 - $\sqrt{-1}$

Find the area of the figure.

Romashka-Z-Leto [24]

Answer:

28+104 = 132cm^2

Step-by-step explanation:

We can find the area of this figure by breaking it into two separate pieces. The top is a rectangle and the bottom is a trapezoid.

A rectangle = l*w = 7*4 = 28 cm^2

A trapezoid = 1/2 (b1+b2) *h = 1/2 (19+7) *8 = 1/2 (26)*8 =104 cm^2

Add these areas together

28+104 = 132cm^2

AB = 10 in; AD = 6 in A= 30sqrt3 in2 30 in2 60 in2

Ratling [72]

Answer: 30

Step-by-step explanation:

If we were to draw diagonal BD, then we would create two congruent triangles, and we could find the area of each using the formula $A=\frac{1}{2} ab \sin C$ .

However, since there are two triangles, we can double this, giving us $A=ab \sin C$ .

So, the area is $A=(10)(6)(\sin 30^{\circ})=\boxed{30}$

Write an equation of the line in slope intercept form

Nastasia [14]

Answer:

Step-by-step explanation:

(2 - 3)/(4 - 0) = -1/4

y - 2 = -1/4(x - 4)

y - 2 = -1/4x + 1

y = -1/4x + 3
