A volleyball reaches its maximum height of 13 feet, 3 seconds after its served. Which of the following quadratics could model th
e height of the vollyball over time after it is served. Select all that apply. A: f(x)=2x^2+12x+5
B: f(x)=-2x^2+12x-5
C: f(x)=-2x^2-12x+5
D: f(x)=-2(x-3)^2+13
E: f(x)=-2(x+3)^2+13
Hello here is a solution : <span> the radius of the circle is OA A(5;-12) and O (0;0) OA= </span><span> square root ((5-0)² + (-12-0)²) </span> = <span> square root (25+144) </span> = <span> square root(169) </span> OA = 13
