Answer:
C. a number whose square root is a whole number
Step-by-step explanation:
A number whose square root is a terminating decimal is not a perfect square.
A negative whole number cannot be a perfect square.
A number times itself is squared, the number itself is not a perfect square.
The correct answer is option C, a number whose square root is a whole number. For example: 4 is a perfect square.
The square root of a perfect square is always a whole number.

The given model would make the least sense to use for x=-2.75.
the given function is:
a quadratic relationship,
where
h is the height in feet
x is the time in seconds
<h3>what is kinetic energy?</h3>Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
as we know that time always appears to run forward, never backward. cannot take negative values so option 1 i.e 2.75 is not possible. Also, after a certain period of time object will vanish all its kinetic energy, resulting in h=0 but h(-2.75)= -21 which is meaningless.
h(-2.75) =
h(0.25) =
h(1.75) =
h(25) =
therefore, x=-2.75 this model would make the least sense to use
