The concentration of a drug in an organ at any time t (in seconds) is given by s 0.25t - 15(1 - e-t/60) if osts 20 | 15e-t/60 – 10e-(t - 20)/60 if t> 20 where c(t) is measured in milligrams per cubic centimeter (mg/cm3). (a) What is the initial concentration of the drug in the organ? 0 mg/cm3 (b) What is the concentration of the drug in the organ after 14 sec? (Round your answer to three decimal places.) x mg/cm3 38 (c) What is the concentration of the drug in the organ after 40 sec? (Round your answer to three decimal places.) mg/cm3 Need Help? | Read It

Step-by-step explanation:
the formula for the circumference of a circle is
C = d
with d= diameter

C ≈ 51.52 miles
Answer:
M= -4/2 B=5
Step-by-step explanation:
First we know that when a line is slanted like this \ it is automatically negative. So then we plot 2 points on the line , make a right traingle and count the points across the x axis and then up the Y axis . X will be on the bottom(2) and Y on the top(4). Add the negative sign. Therefor M = -4/2
Now to find B we need to find the point where the line intercepts the Y axis. we see that it touches the Y axis at 5. Therefor B= 5
