This is a warmup for your first project. The drug valium is eliminated from the bloodstream through a decay process with a half-

frosja888 [35]

Step-by-step explanation:

a. We have v as the amount of drug(mg) in the blood at time t (hrs)

b. Flow rate in = k litre/he

For a circulatory system we have the flow rate in and flow rate out to be the same

Therefore,

Flow rate out = k litre/hr

concentration of drug going in = 0mg/litre

Concentration of drug going out = v mg/litre

V(0) = 20mg since 20mg was taken at midnight

V(0) = 20

Half life t1/2 = 36 hours

V(36) = v(0)/2

= 20/2

= 10mg

C. $ivp = \frac{dv}{dt}$ $= -kv$

$v(0) = 20mg\\v(36) = 10mg$

d. solution

$\frac{dv}{dt} = -kt\\ln(v) = ln(c) - kt$

$\frac{v}{c} = e^{-kt} = v=ce^{-kt}$

v(0) = 20

$ce^{-k(0)} =20$

c = 20

so

$v(t) = 20e^{-kt}$

e.

$t\frac{1}{2}=36hours\\ v(36)= 10$

$10 = 20e^{-36k}$

$\frac{1}{2} =e^{-36k}$

we take log

$k=\frac{ln(2)}{36}$

Ms.Anlonzo orderd 4,000 markers for her store.Only 1 tenth of them arrived.How many markers did she receive?

PSYCHO15rus [73]

So only 1/10 of 4000 markers arrived.

So 1/10, or 0.1 of 4000, can be found by multiplying 1/10 by 4000.

1/10 * 4000 = 400

So she received 400 markers.

If z is inversely proportional to r, and z= 32 when r=1.5, find r when z=8.

lions [1.4K]

Inversely proportional: z = k/r
k = 32 * 1.5 = 48
Plug that into equation
8 = 48/r
Multiply both sides by r
8r = 48
Divide by 8
r = 6
