Ariana has a large piece of fabric that she wants to use to make some scarves. The number N of scarves she can make is inversely

AveGali [126]

Answer:

9 scarves.

Step-by-step explanation:

We have been given that the number N of scarves Ariana can make is inversely proportional to the area A of each scarf.

We know that equation of two inversely proportional quantities in in form $y=\frac{k}{x}$ , where, k is constant of variation and y is inversely proportional to x.

Let us find constant of variation using our given information.

$N=\frac{k}{A}$

$15=\frac{k}{3}$

$15*3=\frac{k}{3}*3$

$45=k$

Now, we will substitute $A=5\text{ and }k=45$ in our equation to solve for N.

$N=\frac{45}{5}$

$N=9$

Therefore, Ariana can make 9 scarves.

PART A) the initial value of the function is 150 at 0 weeks, that means that there are still 150 songs to be downloaded at the beginning.
 The rate of change is -30 songs each week, that is because the amount of songs left to be downloaded decrease by 30 each week.

PART B:
 lets use 2 points of the graph p1(0, 150), p2(1, 120)
calculate the slope:
m = (y2- y1)/(x2 - x1) = (120 - 150)/(1 - 0)
m = -30
and now use line equation in form point-slope:
y - y1 = m(x - x1)
y - 150 = -30(x - 0)
y = -30x + 150
