Answer:

  • k = 2

Step-by-step explanation:

<u>Take some reference points on the graph of f and g:</u>

  • f(2) = 1, g(2) = 2
  • f(4) = 2, g(4) = 4
  • f(8) = 4, g(8) = 8

<u>According to the numbers above we can state:</u>

  • g(x) = 2f(x)

So the value of k is 2

Again, look for repeated entries in the domain.  If present, the relation cannot be a function.  1 maps 6 to 1, 2, and 3; 2 maps 5 to -1 and 9; 3 maps 1 to -6 and 0; and only 4 has no double mapping.  Therefore 4 is a function and the answer.

Answer:

59)

Therefore the height of the pyramid is 14 meter.

60)

Therefore the Diameter of Cone is 17.32 cm.

Step-by-step explanation:

59 )

Given:

Shape is Rectangular Pyramid,

Length = 3 meter

Width = 8 meter

Volume of Rectangular Pyramid = 112 cubic meter

To Find:

Height:

Solution:

We Know,

\textrm{Volume of Rectangular Pyramid}=\frac{1}{3}(Length\times Width\times Height)

Substituting the given values we have

112=\frac{1}{3}(3\times 8\times Height)\\ \\\therefore Height=\frac{336}{24}\\\\\therefore Height=14\ meter\\

Therefore the height of the pyramid is 14 meter.

60 )

Thee shape is of Cone

Given:

Height= 5 cm

Volume of cone = 125 π cm³

To Find:

Diameter of a cone = d = ?

Solution:

We know,

\textrm{Volume of cone}=\frac{1}{12}\pi (Diameter) ^{2}\times Height

Substituting the given values we have

125\pi =\frac{1}{12}\pi  d^{2}\times 5\\ \\d^{2}=25\times 12\\  \\d^{2}=300\\\\d=17.32\\   \therefore Diameter = 17.32\ cm

Therefore the Diameter of Cone is 17.32 cm.

X^2 - 18x + 81 = 0 x=?
levacccp [35]

Answer:

x = 9

Step-by-step explanation:

Solve for x:

x^2 - 18 x + 81 = 0

Write the left hand side as a square:

(x - 9)^2 = 0

Take the square root of both sides:

x - 9 = 0

Add 9 to both sides:

Answer:  x = 9
