Answer:
12
Step-by-step explanation:
Given that the concentration has been modeled by the formula:
C(t)=50t/(t^2+25)
where:
t is time in hours.
The concentration after 5 hours will be given by:
t= 5 hours
plugging the value in the equation we get:
C(5)=(50(5))/(5^2+25)
simplifying the above we get:
C(5)=250/(50)=5 mg/dl
Answer: 5 mg/dl
Answer:
x = 3
Step-by-step explanation:
8x -6 = 18
Add 6 to both sides.
8x = 24
Divide both sides by 8 to isolate x.
x = 3
