Answer:Length and angle measure
Step-by-step explanation:
The length measure is the distance along the curve (arc) and the angle measure is the angle that the arc makes with the center of the circle.
2,2 and 4.5 would be a circle in this point
Answer:
Compound Events
Step-by-step explanation:
What operations would the set of quadratics be closed under? For each operation, explainwhy it is closed or provide an example showing that it isn’t.Type your response here:x^2-1+(x^2+2x+1)=2x^2+2x closed under addition.(x^2-1)-(x^2+2x+1)=-2x-2 not a quadratic(x^2-1)(x^2+2x+1)=x^4+2x^3-2x-1 no above degree 2(x^2+2x+1)/(x^2-1)=1+(3x+1)/(x^2+2x+1) not a quadratich. Is there a set of expressions that would be closed under all four operations? Explain.Type your response here: Polynomials with a degree of 0, real numbers, andrational numbers.
