Answer:
A counterexample for a conjecture is the statement that disproves a conjecture.
Step-by-step explanation:
To find : What is a counterexample for the conjecture?
Solution :
A conjecture is an educated guess but not yet proven. It is possible that next example shown the conjecture wrong.
A counterexample is an example that disproves or disagree a conjecture.
For example : Prime numbers - 3,7,11,23
Conjecture - All prime numbers are odd
Counterexample - 2
→ 2 is a prime number but not odd, it is an even number.
Answer:
4x² - x - 1
Step-by-step explanation:
(f - g)(x) = f(x) - g(x) , thus
f(x) - g(x)
= 4x² - (x + 1) ← distribute parenthesis by - 1
= 4x² - x - 1

Answer:
Step-by-step explanation:
1st . 1.3^2= 1.69
1.4^2= 1.96
It's not bettween 1.3 & 1.4
2. 1.4^2=1.96
1.5^2= 2.25
it's betteen 1.4 & 1.5
3 . 1.4 & 1.5 so it's eqaul 1.4
Answer:
In terms of Pi: 
km
Exact value (rounded): 15.42477 km
Approximated (3.14): 15.42 km
Step-by-step explanation:
Hello!
A semicircle's perimeter can be found using the formula: 
We can plug in the values to solve for the perimeter.
<h3>Solve</h3>
In terms of Pi, it is ,
Exact value of Pi, it is 15.42477
Approximation of Pi (3.14), it is = 15.42
