Answer:
Step-by-step explanation:
Given there are 12 babies in a photograph ,Out of which 9 babies have their eyes open .So by intuition one can say that the other babies have their eyes closed.Let the number of babies with their eyes closed be "c". Then
Total number of babies=12
number of babies with their eyes open=9
number of babies with their eyes closed=c
Total number of babies= number of babies with their eyes open + number of babies with their eyes closed.

Answer:
The depth of the reflector is 0.84 feet
Step-by-step explanation:
<em>(See the figure below)</em>
The equation of a parabola centered at the origin with an axis of symmetry on y-axis is:
(1)
With p the distance from the origin to the focus using p=6, the equation (1) of the parabola becomes:
(2)
Note that the point B is on the parabola, so this point should satisfy the parabola equation (2) that allow us to use the value x=4.5 to find the y value associated to it, that it is the depth (h) of the reflector:
, solving for y
