Is there some type of image for this?
Answer: The 1st option is correct! :D
Hopefully this will help others as well!
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
We can observe relationship between demand and price in the sense that, price of a commodity can influence the demand for such commodity. However, we must understand that price is usually not the only explanatory variable for demand in most cases.
Meanwhile, for this question, demand is the dependent variable because it is a function of price. That is:
==> Demand = f(Price)
And price is the independent variable.
We assume that if price of a commodity increase, the demand will decrease if there is a substitute goods in the market.
But, in a monopoly, any increase in price of the commodity might cause decrease in demand only for a while particularly if such goods is a daily necessities. This is largely due to the fact that, the consumers has no other substitute and the goods is important to their daily needs. Hence, any increase in price will rather cause economic hardship on the consumer in a monopoly market.
In conclusion, price determines demand! Thus, the situation can be described by a function. The dependent variable is the demand and the independent variable is the price.
Answer:
a = 15
Step-by-step explanation:
Substitute b = 12 , a = 9 into the equation
12 = 
12 = 
← square both sides
144 = a² - 81 ( add 81 to both sides )
225 = a² ( take square root of both sides )
± 
= a , then
a = ± 15
a > 0 , so a = 15
Answer:
25%
Step-by-step explanation:
Let us first derive an equation for the productivity.
Given
No. of houses = 1 (Assumption)
Amount of Chemicals = 30 (10 x A, B, C)
Now the formula for productivity is as follow
Productivity % (P) = (Output/Input) * 100
Assuming the current productivity is 100%. We get the value for required output but using the value of 30 (Amount of Chemicals) as Input
Since we now know the value for desired output. We replace the value of input by 40, since 10 lbs of Chemicals have been increased per house.
The new Productivity is 75%
There is a reduction of 25% in productivity
