The office manager ordered 140 reams of printer paper. Based on average daily use, they know that 140 reams of paper will last a

Paul [167]

Let

x--------> the number of days

y--------> the number of reams of paper

we know that

For x=0 days y=140 reams of paper--------> point A(0,140)

<u>The point A is the y-intercept </u>-----> remember that the y-intercept is the value of y when the value of x is equal to zero

For x=80 days y=0 reams of paper--------> point B(80,0)

<u>The point B is the x-intercept </u>-----> remember that the x-intercept is the value of x when the value of y is equal to zero

Step 1

Find the equation in slope-intercept form

<u>Find the slope of the points A and B</u>

m=(y2-y1)/(x2-x1)

substitute

m=(0-140)/(80-0)-------> m=-140/80

$m=-1.75 \frac{reams}{day}$

the equation in slope-intercept form is equal to

y=mx+b

b is the coordinate of y in the y-intercept point

so

b=140

substitute

$y=-1.75x+140$

therefore

<u>the answer part 1) is </u>

the equation in slope-intercept form is equal to $y=-1.75x+140$

Step 2

<u>Find the reasonable domain for this situation</u>

the domain are the values for x

$x\geq0\\x\leq 80\\0\leq x \leq80$

therefore

the domain is the interval-------> [0,80]

Step 3

Find the reasonable range for this situation

the range are the values for y

$y\geq0\\y\leq 140\\0\leq y \leq140$

therefore

the range is the interval-------> [0,140]

Step 4

What is the rate of change and what does it represent?

the rate of change is the slope of the equation of the line

in this problem

$m=-1.75\frac{reams}{day}$

the rate of change represents the amount of reams that are consumed per day, is negative because each day is becoming smaller

Step 5

What does the x-intercept represent in this situation?

For x=80 days y=0 reams of paper--------> point B(80,0)

<u>The point B is the x-intercept </u>-----> remember that the x-intercept is the value of x when the value of y is equal to zero

The x-intercept represents the day 80, day in which the amount of reams is zero

Step 6

What does the y-intercept represent in this situation?

For x=0 days y=140 reams of paper--------> point A(0,140)

<u>The point A is the y-intercept </u>-----> remember that the y-intercept is the value of y when the value of x is equal to zero

The y-intercept represents the day 0, day in which the amount of reams is 140

Elena L [17]

Answer:

20:5

Step-by-step explanation:

1. What is the ratio for B and H?

Ratio = 4 to 1 or 4:1

2. What is the question asking?

The question is increasing 5 to 20. What is the quotient of 20 and 5? 4! The question is basically multiplying B by 5. Now, since math is a very jealous subject, it needs to be done on the other side too! So you need to multiply the B, which is 1, by 5.

3. 1 x 5?

5

4. Answer

So, since B is 20 and H is 5, the ratio would be 20:5!

Hiii, so I REALLY want to rank up, and I just need 4 more Branliests, so if you liked my answer, can you please give me one? Thank you so much, and thanks for the points!!

Which of the following functions represent exponential decay?

Zina [86]

Option C: $f(x)=3^{5}\left(\frac{1}{3}\right)^{x}$ is the function that represent exponential decay.

Explanation:

The exponential decay can be represented by

$f(x)=a \cdot b^{x}$ where $a>0$ and $0$

Option A: $f(x)=3(1.7)^{x-2}$

From the function, we can see that $a=3$ and $b=1.7$

Thus, $a>0$ and $b>1$

Thus, the function $f(x)=3(1.7)^{x-2}$ does not represent exponential decay.

Hence, Option A is not the correct answer.

Option B: $f(x)=3(1.7)^{-2 x}$

From the function, we can see that $a=3$ and $b=1.7$

Thus, $a>0$ and $b>1$

Thus, the function $f(x)=3(1.7)^{-2 x}$ does not represent exponential decay.

Hence, Option B is not the correct answer.

Option C: $f(x)=3^{5}\left(\frac{1}{3}\right)^{x}$

From the function, we can see that $a=3^5=243$ and $b=\frac{1}{3} =0.3333$

Thus, $a>0$ and $0$

Thus, the function $f(x)=3^{5}\left(\frac{1}{3}\right)^{x}$ represent exponential decay.

Hence, Option C is the correct answer.

Option D: $f(x)=3^{5}(2)^{-x}$

From the function, we can see that $a=3^5=243$ and $b=2$

Thus, $a>0$ and $b>1$

Thus, the function $f(x)=3^{5}(2)^{-x}$ does not represent exponential decay.

Hence, Option D is not the correct answer.
