An epidemic has hit clinton city. its population is declining 22% every hour. in just 4 hours, there are only 35,542 people left in the city. what was the initial population in the city before the epidemic broke out?

85688

Step-by-step explanation:

The exponential decay function is given by :-

, where A is the initial amount , r is the rate of decay (in decimal) and t is the time period.

The according to the question we have :_

Hence,  the initial population in the city before the epidemic broke out= 85688

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

∞ this is your sign
