Answer:
A) rate of change would be dividing the number of songs wanted (150) by the number of weeks downloading (5)
150/5 = 30
since the total quantity wanted is becoming less every week the rate of change would be negative so it becomes -30
Initial value is 150, which is the total number of songs they want
B) rate of change would be dividing the number of songs wanted (150) by the number of weeks downloading (5)

Answer:
15:17
Step-by-step explanation:
Since the triangle has a right angle, we may find the length of the unknown side using the trigonometric notations SOH CAH TOA where
SOA stands for
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
With respect to ∠B given that ∠D=90°,
BD is the adjacent side
CB is the hypotenuse side
and DC is the opposite side
Hence Sin B = 15/17
Answer:
the answer is (-2,2)
Step-by-step explanation:
Answer:
f(x) = 4/7x + 20/7
Step-by-step explanation:
If we were to graph this function, we would see that the two points would be, (-5, 0), and (2, 4). First, we have to find the slope, which is equal to:
<u>(first y-coordinate - the second y coordinate)</u>
(first x-coordinate - second x coordinate)
= <u>(0 - 4)</u>
(-5 - 2)
= -4/-7 = 4/7. now, we multiple -5 by 4/7 and get -20/7. we have to add 20/7.
Thus, the answer is f(x) = 4/7x + 20/7
