What is the equation of the line graphed below?
andrew-mc [135]

Answer: y=-\frac{1}{3}x

Step-by-step explanation:

From the origin we can see to get to the point plotted we have to go down 1 and right three giving us the slope \frac{-1}{3}

These are in the form of y=mx+b

b is the y-intercept and m is the slope

since the y-intercept is 0 b is 0 and isn't need leaving us with y=mx

We can put our slope into the equation giving us the answer in C

Nana has a water purifier that filters \dfrac13 3 1 ​ start fraction, 1, divided by, 3, end fraction of the contaminants each ho
Fiesta28 [93]

Given:

Nana has a water purifier that filters \dfrac{1}{3} of the contaminants each hour.

Water has contaminants = \dfrac{1}{2}

To find:

The function that gives the remaining amount of contaminants in kilograms, C(t), t hours after Nana started purifying the water.

Solution:

Let C(t) be the remaining amount of contaminants in kilograms after t hours.

Initial amount of contaminants = \dfrac{1}{2}

Decreasing rate is \dfrac{1}{3} .

Using the exponential decay model:

C(t)=C_0(1-r)^t

where, C_0 is initial amount of contaminants, r is the decreasing rate and t is time in hours.

Substituting the values, we get

C(t)=\dfrac{1}{2}(1-\dfrac{1}{3})^t

C(t)=\dfrac{1}{2}(\dfrac{2}{3})^t

Therefore, the required function is C(t)=\dfrac{1}{2}(\dfrac{2}{3})^t.
