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

Compare the perimeter and area of the original figure to the perimeter and area of the reduced figure using the scale factor. A
Serggg [28]

Answer:

- The scale factor is one-half

- The perimeter of the model is the product of the scale factor and the perimeter of the original rectangle

-The area of the reduced figure is (1/2)^2 = 1/4 times the area of the original figure

Step-by-step explanation:

The ratio of the length of the original rectangle to that of the reduced rectangle is 6 to 3, or a factor of 1/2. The ratio of the width of the original rectangle to that of the reduced rectangle is 2 to 1, or, again, a factor of 1/2. So, because this ratio of 1/2 is constant, we know the total scale factor is 1/2, making B correct.

The perimeter of a rectangle is: P=2l+2w, where l is the length and w is the width. The perimeter of the reduced figure is: P = 2 * 3 + 2 * 1 = 6 + 2 = 8 units. The perimeter of the original figure is: P = 2 * 6 + 2 * 2 = 12 + 4 = 16 units.

Notice that 16 * (1/2) = 8, which means that the perimeter of the scale-factored, reduced rectangle is "the product of the scale factor (which is 1/2) and the perimeter of the original rectangle (which is 16)". So, C is correct.

The area of a rectangle is: A=lw, where l is the length and w is the width. The area of the reduced figure is: A = 3 * 1 = 3 units squared. The area of the original figure is: A = 6 * 2 = 12 units squared.

Notice that 12 * (1/4) = 3, which means that E is correct, but D is wrong.

Hope this helps!
