In a village, the cases of a particular infectious disease have been exponentially decreasing at a rate of 95% per year since the people started receiving the vaccine. If there were 200 cases in the village to start with, predict the number of cases after 2 years. First, complete the equation: Remaining Amount = 200(1 - [?])0

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer:

c) the x-coordinate of the center of the circle increases by 3
