Answer:

Step-by-step explanation:
A)360/6 = 60. 180-60 =120 degrees i think
b) 360/8 = 32.5. 180-32.5= 147.5 degrees i think
Part 1:
Given that a<span>
store had 235 MP3 players in the month of January and that every month, 30% of
the MP3 players were sold and 50 new MP3 players were stocked in the
store.
</span>The number of MP3 players in the store after the previous months sale is given by 0.7f(n - 1) and <span>the number of MP3 players in the store after new MP3 were added is 0.7f(n - 1) + 50.
Therefore, the </span><span>recursive function that best represents the number of MP3 players in the store f(n) after n months is given by </span><span>f(n) = 0.7 x f(n − 1) + 50, f(0) = 235, n > 0
Part 2:
The average rate of change of a function from a to b is given by

Given that the </span><span>equation showing the value of her investment after x years is given by

Thus, </span><span>the average rate of change of the value of Sophia's investment from the second year to the fourth year is given by

Therefore, the </span><span>average rate of change of the value of Sophia's investment from the second year to the fourth year is 28.25 dollars per year.</span>
