Step-by-step explanation:

Given function:

y = |x + 4| - 1

See the graph below

According to the graph we see that

The minimum is (-4, -1) and zero's are (-5, 0) and (-3, 0)

Function is positive:

When x < - 5 and x > -3

Negative:

When x is between -5 and -3

Increasing:

When x > -4

Decreasing:

When x < -4

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

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

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

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

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

we take log

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

Mark bought a notebook for $1.45 and some pencils for $0.42 each. If the total cost was $6.91, how many pencils did he buy?

Lesechka [4]

B - 13

Okay, we know that Mark brought 1 notebook and the totally is 6.91 while one pencil costs $0.42.

x= number of pencils he brought.
we know the price of 1 notebook + the cost of pencils times the numbers of pencils he brought = total cost.

So the equation will be:

1.45 + 0.42x = 6.91 subtract 1.45 on both sides.
0.42x = 5.46 Then we solve for x by dividing both sides by 0.42
x= 13

So the number of pencils he brought is 13.
