Q. Guillermo is a professional deep water free diver. His altitude (in meters relative to sea level), x seconds after diving, is modeled by g(x)=201x(x−100) How many seconds after diving will Guillermo reach his lowest altitude? seconds
Find Parabola Vertex: To find the lowest altitude, we need to find the vertex of the parabola represented by g(x)=201x(x−100).
Vertex Form Explanation: The vertex form of a parabola is g(x)=a(x−h)2+k, where (h,k) is the vertex.
Calculate x-coordinate of Vertex: The x-coordinate of the vertex, h, is the value of x that makes x(x−100) equal to zero. This is the average of the roots of the equation x(x−100)=0.
Find Roots of Equation: The roots of the equation x(x−100)=0 are x=0 and x=100.
Calculate Average of Roots: The average of the roots is (0+100)/2=50.
Final Result: So, the x-coordinate of the vertex is 50, which means Guillermo will reach his lowest altitude 50 seconds after diving.
