Answer:
It is Commutative
Step-by-step explanation:
An operation ∆ is said to be Commutative if a∆b=b∆a ∀ a,b ∈ ℝ.
Given the operation ∆ defined by:
a∆b=a X b

a∆b=
=3
Similarly, for the right hand side.

Therefore:
b∆a=
=3
These are the two ways of solving this problem and we have in fact shown that the operation is commutative as:
a∆b=b∆a=3
Answer:
False
Step-by-step explanation:
A number that can expressed as
,
Where, p and q are integers such that q ≠ 0, is called a rational number.
Also, a decimal number with repeating pattern is a rational number,
( for eg : 0.333.... =
)
Since,
√3 = 1.73205080757.....
∴ There is no repeating pattern
Thus, √3 is not a rational number.
Given statement is FALSE.
Answer is:
It includes points in quadrant II and it doesnt include points in quadrant I
Explanation:
For odd functions a rule is:
f(x) = -f(-x) or in other words
f(x) + f(-x) = 0
Because of this function can be in quadrants I and III or in quadrants II and IV as in pairs...
The 20% statement is useless
80% of $295 is what?
80%×295=??
.80 × 295 = $236.00 in savings
