Perfect competition – consider a perfectly competitive market that has 4 firms in it (assume it is perfectly competitive despite their being only 4 firms). two of the firms use technology a and two of the firms use technology b. the respective costs of producing using technology a and b are given by the cost functions: = 40 + + = 30 + + demand is given by ) = 20 − 1 5 p. a) determine short run equilibria, i. e. optimal outputs for each type of firm, equilibrium quantity for the market as a whole, and the equilibrium price, and then calculate equilibrium profits for each type of firm.

b) given your answers regarding profits of the type a and type b firms, what will you expect to happen in the long run? will other firms enter? will price stay the same? how will this impact the two types of firms differently? will both technologies be used in the long run? explain.

i can you with this sweetie!

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
