Q. The number of mosquitoes in Anchorage, Alaska (in millions of mosquitoes) as a function of rainfall (in centimeters) is modeled by:m(x)=−x2+14xHow many centimeters of rain will produce the maximum number of mosquitoes?centimeters
Given quadratic function: We are given the quadratic function m(x)=−x2+14x, which models the number of mosquitoes (in millions) as a function of rainfall x (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 x-coordinate of the vertex will give us the amount of rainfall that maximizes the number of mosquitoes.
Calculating the value of h: The vertex of a parabola given by the function f(x)=ax2+bx+c is at the point (h,k), where h=−2ab. In our case, a=−1 and b=14. Let's calculate the value of h.h=−2ab=−2⋅−114=−−214=7
Rainfall that maximizes mosquitoes: The value of h=7 centimeters represents the amount of rainfall that will produce the maximum number of mosquitoes according to the model m(x)=−x2+14x.
