exponential decay doesnt have to have a decreasing halving time. it just decays at a certain percentage every time, which might be 50% or might not
false
True
positive
A quantity is said to be subject to exponential decay if it decreases at a rate proportional to its value. The time required for the decaying quantity to fall to one half of its initial value.Radioactive decay is a good example where the half life is constant over the entire decay time.In non-exponential decay, half life is not constant.

$75
True
False
That would be an exponential decay curve or negative growth curve.
depends it can be true or false Apex: False

The quantity is decreasing.
No
A signal is a function that represents a physical quantity,a function may be defined by two or more variable. e.g a Sinosoidal signal require three parameters to define it completely that are amplitude,frequency and phase.
a quantity expressed asa number raised to a power
Yes, a value can represent a quantity or amount.
Exponential growth occurs when a quantity increases exponentially over time.
