Solve as a difference equation.
zhannawk [14.2K]

Solution :

Let y = amount of caffeine at a given time in body.

n = number of hours

So $\frac{dy}{dn}= - \ Y$

$\Rightarrow \frac{dY}{Y}=- 0.01 \ dn

ln Y = -0.01 n + C

At n = 0, Y = 130 mg

ln 130 = -0.01 x 0 + C

C = ln 130

$ \ln \frac{Y}{130} =- 0.01 \ n$

$Y = 130 \ e^{-0.01n}$

When Y = 65

$65 = 130 \ e^{-0.01 n }$

$\frac{65}{130}=e^{-0.01n}$

$\ln \frac{1}{2} = -0.01 \ n$

n = 69.315 hours

At n = 24 hours

$Y = 130 \ e^{-0.01 \times 24}$

Y = 102.26 mg

Write an equation for the line in slope-intercept form.
STatiana [176]

Answer:

y=2x+2

Step-by-step explanation:

the equation for slope intercept form is y=mx+b where b is the y intercept and m is the slope. From the graph we can see that where x is 0 y is 2 which makes 2 be the y intercept, and when x is 1 y is 4 which then you replace y for 4 and x for 1 which would be 4=m(1)+2,now u subtract 2 from both sides which leaves you with 2=m(1) and m times 1 is m so now your left with 2=m which means the slop is 2
