Because the altitude of parallelogram is perpendicular to the base and it is the height of the parallelogram so in this way every choices B. and C. are right sure
but than you check so choice - but there is something mistake bc. you wrote two choices D. so the second what say ,,it is used in finding area of a parallelogram" is right too
hope helped

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>
