I think its A hope this helps you
God Bless
Option A.
Step-by-step explanation:
Rational numbers -
- Numbers that can be written as fraction of two whole numbers.
- They can be positive, negative or zero.
- They are numbers that can be written as fractions.
- So, options B and C are examples of rational numbers.
Vinculum or Bar numbers -
- These numbers are repeating decimals.
- They are written with a line or a bar on top of the repeating numbers.
- Bar numbers are irrational numbers.
- So, option A is not a rational number.
This is the concept of quadratic equations, solving the equation 2x^2-12x+20=0 using the formula we get:
x=[-b+/-sqrt(b^2-4ac)]/(2a)
from our equation, a=2,b=-12 and c=20
x=[-(-12+/-sqrt((-12)^2-4*2*20)]/(2*2)
x=[12+/-sqrt(144-160]/4
x=[12+/-sqrt(-16)]/4
x=[12+/-4i]/4
x=[3+\-i]
the answer is A] 3+/-i

16.n=35
Step-by-step explanation:
I think this is asking what power when the first number given is raised to it will equal the number within the parentheses. So, for example, the answer to the first question would be 5 because 2^5 = 32. 10^3 = 1000, so the answer is 3, and so on.
