Answer:
d
Step-by-step explanation:
inverse property of addition is going back to zero with the equation so adding 2 to negative 2 will go back to zero
C= 3.14d
C= 3.14 x 9.06
C= 28.45
4^-5=1/1024 or 2/2048 or 3/3072
PART A)
The rate of change is -40 songs each week, because the amount of songs left to be downloaded decrease by 40 every week.
<span>the initial value is 200 at 0
weeks, which means that there are 200 songs to be downloaded at the
beginning</span>
PART B)
<span><span><span>
<span><span>calculate the slope:
</span><span>
m = (y2- y1)/(x2 - x1) = (160 - 200)/(1 - 0)
m = -40
now use the line equation in form of point-slope
y - y1 = m(x - x1)
y - 200 = -40(x - 0)
y = -40x + 200</span></span>
