Answer:
<h3>The given set of polynomials f(x) and g(x) are closed under subtraction.</h3>
Step-by-step explanation:
Given that the functions f ad g are defined by
and 
respectively.
<h3>To show that the set of polynomials is closed under subtraction :</h3>
Now subtract the given polynomials
∴ 
- When subtracting the polynomials the variables and their exponents remains same only variation in their coefficients.
<h3>Hence the given polynomials f(x) and g(x) are closed under subtraction.</h3>
∴ are closed under subtraction,
Hence showed.
<h3>Given : </h3>
- Radius of circle = 7 inches
<h3>To Find : </h3>
- Circumference of circle = ?
<h3>Solution :</h3>
We are given radius, r = 7 inches
We know that :
Circumference = 2πr
⟹ Circumference = 2π × 7 inches
⟹ Circumference = 14π inches
Hence, circumference of circle is 14π inches.
Answer:
Step-by-step explanation:
Area of sector formula
- A = πr²*θ/360, where θ is the central angle of sector
Substitute and solve
- A = 3.14*6²*60/360 = 18.84 cm²
Correct choice is A
Answer:
4m
Step-by-step explanation:
If you put it into a calculator, you get 35/8 as a fraction and you can change it to a decimal and get 4.375.
