Find three rational numbers between 1 and 0.​

Mathematics
1 answer:
Alex73 [517]3 years ago
4 0

Answer:

1/2, 1/4 & 3/4

Step-by-step explanation:

mean of 0 &1 is\frac{0+1}{2} =\frac{1}{2} \\

mean of 0 and 1/2 is (0+\frac{1}{2} )/2=\frac{1}{2} /2=\frac{1}{2} *\frac{1}{2} =\frac{1}{4}

mean of 1/2 and 1 is (\frac{1}{2} +1)/2=\frac{3}{2} /2=\frac{3}{2} *\frac{1}{2} =\frac{3}{4}

So the three rational numbers are 1/2, 1/4 & 3/4

9. 1/3(x+6) =8
babunello [35]
9.       ¹/₃(x + 6) = 8
    ¹/₃(x) + ¹/₃(6) = 8
           ¹/₃x + 2 = 8
           <u>       - 2  - 2</u>
            3 · ¹/₃x = 6 · 3
                     x = 18

15.       ¹/₅(x + 10) = 6
      ¹/₅(x) + ¹/₅(10) = 6
                ¹/₅x + 2 = 6
                <u>       - 2  - 2</u>
                 5 · ¹/₅x = 4 · 5
                         x = 20

20.       ¹/₈(24x + 32) = 10
      ¹/₈(24x) + ¹/₈(32) = 10
                     3x + 4 = 10
                     <u>      - 4   - 4</u>
                           <u>3x</u> = <u>6</u>
                            3     3
                             x = 2

32.        5 - ¹/₂(x - 6) = 4
      5 - ¹/₂(x) - ¹/₂(-6) = 4
              5 - ¹/₂x + 3 = 4
              5 + 3 - ¹/₂x = 4
                    8 - ¹/₂x = 4
                 <u>- 8            - 8</u>
                -2 · (-¹/₂x) = -4 · (-2)
                             x = 8

33.      ²/₃(3x - 6) = 3
     ²/₃(3x) - ²/₃(6) = 3
                2x - 4 = 3
                <u>    + 4 + 4</u>
                     <u>2x</u> = <u>7</u>
                      2     2
                       x = 3¹/₂

Find the area of the surface the part of the plane y=x^2 y^2 cylinder x^2 z^2=16
Anestetic [448]

The area of the surface is 144.708

The equation of the given surface is,

z=g(x,y)=xy

Solving the partial derivatives,

∂g∂x=y,∂g∂y=x

Substituting to the formula

S=∬√1+( ∂g∂x)2+(∂g∂y)2dA

Thus,

S=∬√1+(y)2+(x)2dAS=∬√1+x2+y2dA

The region in the XY-plane is defined by the intervals  0≤θ≤2π,0≤r≤4

Converting the integral into polar coordinates,

S=∫2π0∫40√1+r2rdrdθ

Integrating with respect to r

S=∫2π0[13(1+r2)32]40dθ

S=∫2π0(17√173−13)dθ

Integrating with respect to θ

S=(17√173−13)[θ]2π0

S≈144.708
