The concentration, in parts per million, of a type of antibiotic in a human's bloodstream after h hours can be modeled by the polynomial -0.06h^2+2h+4=a(h). what is the concentration of the antibiotic after 4 hours

The concentration of antibiotic after 4 hours will be 11.04 ppm (parts per million).

Step-by-step explanation:

Given that the concentration of antibiotics after h hours can be given by the polynomial:

-0.06h^2+2h+4=A(h)

For h=4, equation will be:

-0.06 (4)² + 2 (4)+4= A (4)

11.04 = A (4)

The concentration of antibiotic after 4 hours will be 11.04 ppm (parts per million).
