Suppose that when a perfectly competitive firm produces 500 units of output a day, it earns an economic loss. if the price of each unit of output is $1.50, then, in the short run, it's clear that this firm:
a) is not maximizing its profit.
b) should shut down.
c) should produce more than 500 units a day.
d) should not shut down if its total variable cost is less than $750.

The correct answer is d) should not shut down if its total variable cost is less than $750.

Explanation:

In the event that this value is exceeded, it would not be feasible to continue carrying out the work because they will not obtain returns in the short term and the company does not have other income that will allow it to subsist even in a perfectly competitive market.

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.
