<span><span>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.
</span> 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.</span>
<span><span>PART B:
</span><span> 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</span></span>
Answer:
a = 16 π cm² Exact answer
a = 50.24 cm² Decimal approximation
Step-by-step explanation:
Radius of the circle
16/2 = 8
Area of the circle
a = πr²
a = π4²
a = 16 π cm² Exact answer
a = 16 * 3.14
a = 50.24 cm² Decimal approximation
Answer:
C
HOWEVER: "Less Than" is usually depicted as a dashed line at the border. and there MUST be an OR between these two equations to include all of the blue area. An "and" there would exclude the area between the edge lines.
Step-by-step explanation:
2x + y < 10
y < -2x + 10
3x + 2y < 12
2y < -3x + 12
y < -1.5x + 6
Answer
x+3=17
Step-by-step explanation:
The answer is about 0.02439.
I simply just put it into the calculator.
