Answer:
Step-by-step explanation:
60 · 60 · 60
60³ = 180
Diameter - 8
3 sides, diameter 8 = answer.
You need to use the distance formula to find the radius of the circle.
The radius is 3.
The circumference is
Answer:
Domain: (−∞,∞), {x | x ∈ R}
Range: [3,∞), {y | y ≥ 3}
Graph the equation to find the domain and range.
Yes. When graphed each input will only have one output.
Answer:
f(x) and g(x) are closed under multiplication because when multiplied, the result remains a polynomial.
Step-by-step explanation:
First, to be closed means that once an operation has commenced, the result is a polynomial, just like the two original ones.
When polynomials are multiplied, exponents simply add together, and constants are multiplied. A polynomial is a finite sum of terms in which all variables have whole numbered exponents.
In this scenario, when we multiply polynomials, exponents are solely added together, and one whole number plus another is still a whole number. Similarly, constants multiplied by constants stay as constants, and constants multiplied by variables keeps it in polynomial form. (e.g. 3 * x² makes it 3x², and 3x² is fine in a polynomial).
Therefore, given these facts, f(x) and g(x) are closed under multiplication because when multiplied, the result remains a polynomial.
