Q. The number of mosquitoes in Anchorage, Alaska (in millions of mosquitoes) as a function of rainfall (in centimeters) is modeled by:\newlinem(x)=−x2+14xm(x)=-x^{2}+14x\newlineHow many centimeters of rain will produce the maximum number of mosquitoes?\newlinecentimeters\text{centimeters}
  1. Given quadratic function: We are given the quadratic function m(x)=−x2+14xm(x) = -x^2 + 14x, which models the number of mosquitoes (in millions) as a function of rainfall xx (in centimeters). To find the number of centimeters of rain that will produce the maximum number of mosquitoes, we need to find the vertex of the parabola represented by this quadratic function. The xx-coordinate of the vertex will give us the amount of rainfall that maximizes the number of mosquitoes.
  2. Calculating the value of h: The vertex of a parabola given by the function f(x)=ax2+bx+cf(x) = ax^2 + bx + c is at the point (h,k)(h, k), where h=−b2ah = -\frac{b}{2a}. In our case, a=−1a = -1 and b=14b = 14. Let's calculate the value of h.\newlineh=−b2a=−142⋅−1=−14−2=7h = -\frac{b}{2a} = -\frac{14}{2 \cdot -1} = -\frac{14}{-2} = 7
  3. Rainfall that maximizes mosquitoes: The value of h=7h = 7 centimeters represents the amount of rainfall that will produce the maximum number of mosquitoes according to the model m(x)=−x2+14xm(x) = -x^2 + 14x.
