Suppose a hospital patient receives a medication that is used up in the body according to the equation M=200(0.8)^t with M in milligrams and t in hours. What does 0.8 represent in the equation??

There is 80% of the medication remaining in the patient each hour

Step-by-step explanation:

M = 200(0.8)^t

200 = initial value

0.8 = decay factor

t = time (in hours)

There is 80% of the medication remaining each hour

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
