Answer:
Monopoly, Monopolistic Competition, and Oligopoly.
Step-by-step explanation:
Lets look at each of the options one by one:
Perfect Competition: This type describes a market structure, in which a large number of small firms compete against each other. A single firm does not have any significant market power and so is the seller. As a result, the industry as a whole produces the socially optimal level of output, because none of the firms have the ability to influence market prices.
Monopoly: It is a type of market structure where a single firm or seller controls the entire market. The firm has the highest level of market power because consumers do not have any alternatives. Consequently, monopilists often reduce output deliberately to increase prices and earn more profit.
Monopolistic Competition: It is a kind of market structure, where a large number of small firms or sellers compete against each other but they sell slightly differentiated products. And that gives them a certain degree of market power which allows them to charge higher prices within a certain range.
Oligopoly: In this market structure it is dominated by only a limited number of firms or sellers. Resulting in a state of limited competition. The sellers can either compete against each other or can collaborate. This way they can use their market power to drive up prices and earn more profit.
So basically there are three kinds of market structures in which sellers can have some control over price and they are Monopoly, Monopolistic Competition, and Oligopoly.
Answer:
no real roots
Step-by-step explanation:
9x²+12x+14
recall that for a quadratic equation ax²+bx+c, the discriminant = b²- 4ac
In our case,
discriminant,
= b²- 4ac
= 12² - 4(9)(14)
= 144 - 504
= -360
because the discriminant is negative, there are no real roots.

Answer:
900 times
Step-by-step explanation:
A doctor takes a sample of Laura's blood. There are 
red blood cells and 5000 white blood cells.
Now, we are asked to get how many times more red blood cells are there than white blood cells in the sample.
There were = 4500000 red blood cells in the sample.
Hence, 
And there are 900 times more red blood cells than white blood cells in the sample. (Answer)
