Answer:
7
Step-by-step explanation:
Use secant-tangent product theorem.
1. Set up the equation
(x-3)(x-3+5) = (x-1)²
2. Solve
(x-3)(x+2) = (x²-2x+1)
(x²-x-6) = (x²-2x+1)
3. Solve for x
Subtract x² from both sides
-x-6 = -2x+1
Add 2x and 6 to both sides
x = 7

Answer: Medication in Lexi's system on day t becomes,

Step-by-step explanation:
Since we have given that
Initial amount Sofia takes of a medicine = 10 mg
Concentration in blood decreases by a factor of one half every day.
So, it becomes,

According to question, four days later, it becomes,

We have given that Lexi takes 10 mg of the same medicine.
So, it becomes,

Hence, Medication in Lexi's system on day t becomes,

The nearest hole number would be 4 , if it is .5 and above then it gets rounded up to the next number and if it is .4 or less that you round it to the whole number
