Explanation:

Given that, the height of the tide measured at a seaside community varies according to the number of hours t after midnight. The height is given by the equation as :

$h=-\dfrac{1}{2}t^2+6t-9$

When the tide first be at 6 ft, put h = 6 ft in above equation as :

$-\dfrac{1}{2}t^2+6t-9=6$

$-t^2+12t-18=0$

On solving the above equation to find the value of t. It is equal to :

t = 3.551 seconds

or

t = 8.449 seconds

So, the tide of 6 ft is at 3.551 seconds and 8.449 seconds. Hence, this is the required solution.

A scientist designs an experiment in which a light source is pointed at a substance and a light detector is placed on the opposi

Lostsunrise [7]

The answer is D. Either absorbed or reflected. The reason is because if no light is being shown on the other side, the substance is not letting any light pass through. Since we do not know anything else about the substance, we do not know which one of the two it is doing. The scientist would not see any light on the detector if 100% of the light is reflected and the same thing would happen if 100% of the light was absorbed.
