Answer: OPTION D.
Step-by-step explanation:
The vertex form of a quadratic function is:
Where (h, k) is the vertex of the parabola and "a" is the coefficient of the squared in the parabola's equation.
We know that the vertex of this parabola is at (5,5) and we also know that when the x-value is 6, the y-value is -1.
Then we can substitute values into and solve for "a". This is:
The gievn equation is ,
where t is the time in seconds and h is the no.of hamburgers assembled.
put h = 2 in equation (1).
blank A assembles 2 hamburges in 22.6 seconds.
put h = 3 in equation (1)
blank B assembles 3 hamburgers in 33.9 seconds.
put h = 5 in equation (1)
blank C assembles 5 hamburgers in 56.5 seconds.
put h = 8 in equation (1)
blank D assembles 8 hamburgers in 90.4 seconds.
