A water canal has a rectangular cross section 3 meters wide and 2 meters deep. How much water is contained in a 30-meter length
Alex
Basically you are finding the volume of a rectangular prism of 3 by 2 meters cross section and 30 meters length.  Volume = (3 m)(2 m)(30 m) = 180 cubic meters.

If 60% of the water has evaporated, 40% is left.  Find 40% of 180 cubic meters to answer the 2nd part of this question.

The domain of both
Margarita [4]

Answer:

The domain of function h(x) is set of all real numbers.

Domain: (-∞,∞)

Step-by-step explanation:

Given:

f(x)=x-6

g(x)=x+6

the domain of both the above functions is all real number.

To find domain of :

h(x)=f(x)g(x)

Substituting functions f(x) and g(x) to find h(x)

h(x)=(x-6)(x+6)

The product can be written as difference of squares. [a^2-b^2=(a+b)(a-b)]

∴ h(x)=x^2-36

The degree of the function h(x) is 2 as the exponent of leading term x^2 is 2. Thus its a quadratic equation.

For any quadratic equation the domain is set of all real numbers.  

So Domain of h(x) is (-∞,∞)
