Find a third-degree polynomial equation with rational coefficients that has roots -4 and 6 + i.

dolphi86 [110]

Answer:

x³ - 8x² - 11x + 148

Step-by-step explanation:

Given that x = 6 + i is a root then x = 6 - i is also a root

Complex roots occur as conjugate pairs.

The factors are therefore (x - (6 + i)) and(x - (6 - i))

Given x = - 4 is a root then (x + 4) is a factor

The polynomial is the product of the factors, that is

p(x) = (x + 4)(x - (6 + i))(x - (6 - i))

= (x + 4)(x - 6 - i)(x - 6 + i)

= (x + 4)((x - 6)² - i²)

= (x + 4)(x² - 12x + 36 + 1)

= (x + 4)(x² - 12x + 37) ← distribute

= x³ + 4x² - 12x² - 48x + 37x + 148

= x³ - 8x² - 11x + 148

The surface area of a cone is 54 square inches. What is the surface area of a similar cone that is three times as large?

12345 [234]

<u>Given</u>:

Given that the surface area of the cone is 54 square inches.

We need to determine the surface area of the cone that is similar to the cone three times large.

<u>Surface area of the similar cone:</u>

Let us determine the surface area of the similar cone.

The surface area of the similar cone can be determined by multiplying the surface area of the cone by 3. Because it is given that the similar cone is three times large.

Thus, we have;

$SA = 3 \times 54$

$SA=162$

Thus, the surface area of the similar cone is 162 square inches.

5 more than b divided by 2 is 5

gayaneshka [121]

We have an equation: (5+b)/2= 5
⇒ 5+b= 5*2
⇒ 5+b= 10
⇒ b= 10-5
⇒ b= 5

Final answer: b=5~
