Answer:
The rational roots of the equation are:
x= -1.10355
x= 0.148953
x= 0.706883
x= -1
Step-by-step explanation:
We have to find the rational solutions of the algebraic equation:
This equation could also be written as:
for finding the roots of the equation we have to find the possible values of x.
Clearly the equation has 8 roots as the degree of the equation is 8.
from the graph of the following function we could see that the rational roots of the function are:
x= -1.10355
x= 0.148953
x= 0.706883
x= -1
The rest 4 roots of the equation are the complex roots.
X=15 Alt. Ext. Angles are congruent so just plug 84 into the equation 5x + 9. 84 being x.
The pyrite cube is, well, a cube, so it has a side length <em>s</em> such that the area of its base is
<em>s</em> ² = 5.76 cm²
which means
<em>s</em> = √(5.76 cm²) = 2.4 cm
Then its volume is
<em>s</em> ³ = 13.824 cm³
Pyrite is also known as "fool's gold" because it looks a lot like gold. So if gold has a unit price of €785/cm³, then a pyrite cube with volume 13.824 cm³ could be mistaken for a gold cube of the same volume, which would sell for a price of
(€785/cm³) × 13.824 cm³ = €10,851.80
You would divide 360 by 6 since there are 6 sides. Therefore each exterior angle is 60 degrees
