Express a decimal number ( ie 0.768) - process description please - as a rational number (96/125)?
Stels [109]

The decimal representation of any number is a linear combination of powers of 10. In other words, given a number like 123.456, we can expand it as

1\cdot10^2+2\cdot10^1+3\cdot10^0+4\cdot10^{-1}+5\cdot10^{-2}+6\cdot10^{-3}

10^{-n}=\dfrac1{10^n} for any n, so the above is the same as

100+20+3+\dfrac4{10}+\dfrac5{100}+\dfrac6{1000}=\dfrac{100000+20000+3000+400+50+6}{1000}=\dfrac{123456}{1000}

Similarly, we can write

0.768=\dfrac{768}{1000}

Now it's a question of reducing the fraction as much as possible. We have \mathrm{gcd}(768,1000)=8 so

\dfrac{768}{1000}=\dfrac{96\cdot8}{125\cdot8}=\dfrac{96}{125}

Which represents the inverse of the function f(x) = 4x? h(x) = x + 4 h(x) = x – 4 h(x) = three-quartersx h(x) = one-quarterx
aalyn [17]

Answer:

\large\boxed{f^{-1}(x)=h(x)=\dfrac{1}{4}x}

Step-by-step explanation:

f(x)=4x\to y=4x\\\\\text{exchange}\ x\ \text{to}\ y\to x=4y\\\\\text{solve for}\ y:\\\\4y=x\qquad\text{divide both sides by 4}\\\\\dfrac{4y}{4}=\dfrac{x}{4}\\\\y=\dfrac{1}{4}x

Need help ON THESE TOO PLEASE WILL MARK BRAINLY
LenKa [72]

Answer:

1)

angle 2WZX = angle ZYX ( Since all angles and sides of a rhombus are equal)

ZYX = 2 x 29.5

59

2)

4x - 10 =90 (since all angles of a rhombus intersect at 90°)

x=90+10/4

x=100/4

x=25

hope this helps

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

<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
