Answer:
is irrational
Step-by-step explanation:
Let us assume that is rational. Thus, it can be expressed in the form of fraction 
, where x and y are co-prime to each other.
=
Squaring both sides,
Now, it is clear that x is an even number. So, let us substitute x = 2u
Thus,
Thus, 
is even, which follows the fact that y is also an even number. But this is a contradiction as x and y have a common factor that is 2 but we assumed that the fraction was in lowest form.
Hence, is not a rational number. But is a an irrational number.

Two common points of the graphs (two intersects) means two solutions.
Răspuns:
95.999
Explicație pas cu pas:
Care este cel mai mic număr între 95.999; 96.959; 99.595 și 99.995, unde numărul de mii este 5
95.999 = Nouăzeci și cinci de mii nouă sute nouăzeci și nouă
96.959 = Nouăzeci și șase de mii nouă sute cincizeci și nouă
99595 = Nouăzeci și nouă de mii cinci sute nouăzeci și cinci
99995 = Nouăzeci și nouă de mii, Nouă sute nouăzeci și cinci.
Folosind cunoștințele despre linia numerică:
95.999 <96.959 <99.595 <99.995
Answer:
Step-by-step explanation:
The answer is 1 and 3
m∠BAC = 27°
Solution:
ABCD is a quadrilateral.
AB and CD are parallel lines.
Given m∠BCD = 54°
AC bisect ∠BCD.
m∠DCA + m∠CAB = m∠BCD
m∠DCA + m∠DCA = 54° (since ∠ACB = ∠DCA)
2 m∠DCA = 54°
Divide by 2 on both sides, we get
m∠DCA = 27°
AB and CD are parallel lines and AC is the transversal.
<em>If two parallel lines cut by a transversal, then the alternate interior angles are equal.</em>
m∠BAC = m∠DCA
m∠BAC = 27°
Hence m∠BAC = 27°.
