Are there answer choices i really dont under stand the question
Answer: hello your question is poorly written attached below is the complete question
answer :
a) 31.5
b) 24.5
Step-by-step explanation:
Total world output of good given ( Q ) = qA + qB
world demand ( P ) = 100 - Q
cost function for country A = cA (qA) = 8qA
cost function of country B = cB(qB) = 3qB
total world emission = 0.5Q
emission per unit good = 0.5
<u>a) Determine total world emissions when both countries compete in a Cournot fashion</u>
Q = 63
therefore Total world emission = 0.5 ( Q )
= 0.5 ( 63 ) = 31.5
attached below is the detailed solution
<u>b) Determine the total world emissions after Country A enacts a carbon tax</u>
Q = 49
Therefore Total world emission after tax = 0.5 ( Q )
= 0.5 ( 49 ) = 24.5
attached below is the detailed solution
Answer:
neither
Step-by-step explanation:
The second and 3rd one can be modeled by by y = 100/x but the first one and the fourth one do not follow that, so the answer is neither. The first and fourth are y = 80/x
Put the values in and you will see the equations for yourself.
One
y = 80/2
y = 40
The 80 came from looking at this as an indirect variation. y = k/x
y = 40
x = 2
y = k/x
40 = k/2 Multiply both sides by 2
40 * 2 = k
k = 80
Two
y = k/x
20 = k/5
k = 20 * 5
k = 100
The height of the pole is 12.5 feet.
<h3>What is Unitary method?</h3>
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Cindy's shadow is 5 feet.
length of the shadow of the pole at the same time, she finds it to be 12.5 feet.
So,
12.5/5=x/5,
62.5=5x
x= 12.5 feet.
Hence, the height of the pole is 12.5 feet.
