Write a possible third degree polynomial with integer coefficient that have zeros: 1 2i, -4. Assume the leading coefficient to b
jasenka [17]

Answer:

The polynomial is:

p(x) = x^3 + 2x^2 - 3x + 20

Step-by-step explanation:

A third degree polynomial can be written in function of it's zeros x_1, x_2, x_3 the following way:

p(x) = a(x - x_1)(x - x_2)(x - x_3)

In which a is the leading coefficient.

Integer coefficient that have zeros: 1+2i, 1-2i, -4

Leading coefficient: 1

So

p(x) = 1(x - (1+2i))(x - (1-2i))(x - (-4))

p(x) = (x - 1 -2i)(x - 1 + 2i)(x + 4)

p(x) = ((x-1)^2 - (2i)^2)(x + 4)

p(x) = (x^2 - 2x + 1 - 4i^2)(x + 4)

Since i^2 = -1

p(x) = (x^2 - 2x + 1 + 4)(x + 4)

p(x) = (x^2 - 2x + 5)(x + 4)

p(x) = x^3 + 4x^2 - 2x^2 - 8x + 5x + 20

p(x) = x^3 + 2x^2 - 3x + 20

The median is 18 because if you order the numbers from least to greatest, then cross of the numbers from each side you get 18 in the middle.

There are 16 ounces in one pound. How many pounds<br> are in 80 ounces?<br> nh
gayaneshka [121]

Answer: 5 pounds

Step-by-step explanation: To convert 80 ounces into pounds, first find the conversion factor for ounces and pounds.

Conversion factor ⇒ 1 pound = 16 ounces

Next, notice that we're going from a smaller unit "ounces" to a larger unit "pounds." When we go from a smaller unit to a larger unit we divide.

So we divide 80 pounds by the conversion factor which is 16.

80 ÷ 16 = 5

This means that 5 pounds is equivalent to 80 ounces.
