The concentration of a drug in an organ at any time t (in seconds) is given by C(t) =
0.25 - 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 10 sec? (Round your answer to three decimal places.)
mg/cm
the organ after 26 sec? (Round your answer to three decimal places.)
(c) What is the concentration of the drug
mg/cm3

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
