True or false: an cubic function may have 3 irrational zeros

Mathematics
1 answer:
jolli1 [7]3 years ago
3 0
<h3>Answer: True</h3>

The key word here is "may" meaning that we could easily have 3 rational roots as well. An example of a cubic having 3 irrational roots would be

(x-1)(x-2)(x-3) = x³ - 6x² + 11x - 6

This has the rational roots x = 1, x = 2, x = 3.

However, we could easily replace 1,2,3 with any irrational numbers we want. So that's why the statement "a cubic has three irrational roots" is sometimes true.

In some cases, a cubic may only have 1 real root and the other 2 roots are imaginary.

Illusion [34]

Answer:

D. 1.6 yd

Step-by-step explanation:

Use the law of sines.

\dfrac{c}{\sin C} = \dfrac{a}{\sin A}

\dfrac{c}{\sin 28^\circ} = \dfrac{2~yd}{\sin 36^\circ}

c = \dfrac{2~yd \times \sin 28^\circ}{\sin 36^\circ}

c = 1.6~yd

The areas of two similar triangles are 72dm^2 and 50dm^2. The sum of their perimeters is 226dm. What is the perimeter of each of
Kruka [31]

Answer:

Per2 = 102.727 dm

Per1 = 123.272 dm

Step-by-step explanation:

We know that the area of similar triangles are related to the square of their perimeters.

This means that

(Per1^2)/(Per2^2)  =  Area1 / Area2

If we take the square root of the previous equation

(Per1)/(Per2)  =  \sqrt{Area1 / Area2}

(Per1)/(Per2)  =  \sqrt{72/ 50}

(Per1)/(Per2) = 1.2

We also know that

Per1 + Per2 = 226 dm

So,

1.2*Per2 + Per2 = 226 dm

2.2*Per2 = 226 dm

Per2 = 102.727 dm

Per1 = 1.2*Per2 = 123.272 dm
