After doing the research, he found out that demand for mask N95 are growing at a rapid pace continuously and in the near future the demand will not be declining. Taking advantage of this opportunity, he developed his website and social media pages and he approached a marketing research firm to provide the demand function for this particular business. A predicted demand function given by firm is

q= f(p) =1800-7.5 p

a. Determine the quadratic total revenue function. R=h(p)
b. What is the concavity of the function?
c. What is q-intercept?
d. What does total revenue of Ahmed business equal at a price of $50?
e. How many mask N95 will be demanded at this price?
f. At what price will total revenue be maximized?

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
