What is the constant of proportionality in the equation?
IrinaVladis [17]

Answer:

The constant of proportionality is option D i.e 5.

Step-by-step explanation:

Variation:

Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. There are two types of variation i.e.

  1. Direct variation
  2. Inverse variation

Direct Variation:

Mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.

Example y=kx

where, k  is constant of proportionality.

The above given example is of Direct Variation

∴ y = 5 x

∴ k = 5 = constant of proportionality.

Inverse Variation:

Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.

Example yx=k

where, k  is constant of proportionality.

X^lg(x)=100^x find x
Wittaler [7]

x^lg(x)=100^x<span>
</span>


X^lg(x)=100^x:x  |Solve \ for \ x|


<span>|Use \ logarithms \ of \ both \ sides \ of \ the \ base \ 10|&#10;&#10;</span>

<span>
</span>

<span>lg (x ^ lg (x)) = lg (100x)&#10;&#10;</span>

<span>
</span>

<span>lg ^ 2 (x) = 2 + lgx</span>

<span>
</span>

lg 2 ^ x-lg x -2 = 0


lg x = 2 x = 100


lg x = -1 x = \dfrac{1}{10} = 0.1
