1. Which expression is a cubic polynomial?3x^2 - 1
x^3 - 1
x^2 - x + 3
3x^2 - x + 3

2.Which of the following binomials is a factor of x^3 + 4x^2 +x - 6?

3. If a polynomial equation p(x) = 0 has 3 + 4i as a solution, what other solutions must it have?

Answers

1. A cubic polynomial is a polynomial of degree 3 (the degree of a polynomial is the highest degree among al terms), then the cubic polynomial is $x^3- 1$ .

2. The polynomial $x^3 + 4x^2 +x - 6$ has root x=1, then $x^3 + 4x^2 +x - 6=(x-1)(x^2+5x+6)=(x-1)(x+2)(x+3)$ .

3. If a polynomial equation p(x) = 0 has 3 + 4i as a solution and has real coefficients, then 3-4i is also a solution.

Answer:

1. x^3 - 1

2. P(x) = (x + 5)(x + 2)(x)

3. x + 2

4. 3 - 4i

The length of the wing of an insect in a picture is 4 cm. The scale of the picture is 20:1. What is the real length of the insect’s wing?

Answers

If you would like to know the real length of the insect's wing, you can calculate this using the following steps:

1/20 of 4 cm = 1/20 * 4 = 4/20 = 1/5 cm = 0.2 cm

The correct result would be 0.2 cm.

0.2cm
Working;
Since the picture is a magnification of the insect, the real insect is smaller than the picture

If 20cm on the picture is equivalent to 1 cm of the real insect, then;
$(4*1)/(20) =0.2cm$
