Answer:

Step-by-step explanation:

We see that we can factor out 2x from the equation! So our equation becomes 2x(x-2) = 0.

Since the only way for things to multiply to equal to zero is if at least one of the numbers is 0.

So if x-2 is the 0, then x = 2.

If 2x is the 0, then x = 0.

So our answer is C. 0,2

Consider two countries, A and B, whose respective industries produce goods A and B. Total world output of the good is given by Q

castortr0y [4]

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

a) Determine total world emissions when both countries compete in a Cournot fashion

Q = 63

therefore Total world emission = 0.5 ( Q )

= 0.5 ( 63 ) = 31.5

attached below is the detailed solution

b) Determine the total world emissions after Country A enacts a carbon tax

Q = 49

Therefore Total world emission after tax = 0.5 ( Q )

= 0.5 ( 49 ) = 24.5

attached below is the detailed solution

Can someone please help me with this question? Thank you!

Goryan [66]

Answer: A

Step-by-step explanation:

$\stackrel\frown{XY}$ ≅ $\stackrel\frown{YZ}$

⇒ ∠XOY ≅ ∠ZOY

$\overline{XO}$ ≅ $\overline{ZO}$ since they are both a radius

$\overline{OY}$ ≅ $\overline{OY}$ based on reflexive property

∴ ΔXOY ≅ ΔZOY by SAS

So, $\overline{XY}$ ≅ $\overline{ZY}$ by CPCTC

ZY = 10.2 is given

so, XY = 10.2 by substitution property

Formula: total = principal x (1 + (interest rate x loan time))

total = 1000 x (1 + (0.055 x 2))

total = 1000 x (1 + 0.11)

total = 1000 x 1.11

total = $1110
