Answer: B. exponential decay
Step-by-step explanation:
From the given table, we can observe that y is decreasing as x is increasing.
So it must be a decay function.
Also it can not models a linear relationship, since the rate of change is not constant throughout the table.
then it must be exponential decay function.
An exponential decay is represented by
. where x is the time period, A is the initial amount and r is the rate of decay
Just a couple of rules are needed to solve this.
a) When secants cross inside a circle, the measure of the angle where they cross is the average of the measures of the intercepted arcs.
b) When secants meet outside the circle, the measure of the angle where they meet is half the difference of the measures of the intercepted arcs.
c) As a corollary to the first rule, if the secants meet on the circle, the angle where they meet is half that of the intercepted arc (because the other angle in the averge is zero).
