Answer:
√21
Step-by-step explanation:
<u><em>Irrational number:-</em></u>
An irrational number is a type of real number which cannot be represented as a simple fraction . it cannot be expressed in the form of a ratio.
Example:-
√2,√3, ,......
Given option
√21 is a irrational number
A factor of 2 can be removed from the given line to put it in standard form. Then the given point can be substituted to find the new constant.
2x - y = 2(0.5) - 7 = -6
The equation you seek is
2x - y = -6

Answer:
Approximate length of the diagonal fencing needed is 45.25 cm.
Step-by-step explanation:
Here, each side of the square shaped land = 32 ft
Now, the diagonal fencing is made in side the plot so that the land is divided into two right triangles.
<u>In the triangle:</u>
Base side of the triangle = 32 cm
Perpendicular length of the triangle = 32 cm
Let us assume the hypotenuse of the triangle = k cm
⇒The length of the diagonal in the square = k cm
by <u>PYTHAGORAS THEOREM</u> in a right angled triangle:

⇒
or, k = 45.25 cm
Hence,the approximate length of the diagonal fencing needed to fence the square land is 45.25 cm.
