Suppose that a rectangle has an area of 54 square meters. Express the perimeter P as a function of the length x of one of the si

Lapatulllka [165]

Answer:

$P(x) = 2\left(x+\dfrac{54}{x}\right)$

Step-by-step explanation:

The area of the rectangle can be written as:

$A = x*h$

here, x is one side length, and h is the other side length. This area is said to be equal to 54 square meters.

$54 = x*h$

The perimeter of a rectangle can be written as:

$P = 2x+2h$

To express perimeter only in terms of x (in other words making it a function P(x)). we need to replace h. And this can be done by using the equation of area that we derived earlier.

$54 = x*h$

$h=\dfrac{54}{x}$

now we can substitute this 'h' into our equation of the perimeter.

$P = 2x+2\left(\dfrac{54}{x}\right)$

$P = 2\left(x+\dfrac{54}{x}\right)$

and voila! we have expressed P in terms of x only.

this can be written as P as a function of x as:

$P(x) = 2\left(x+\dfrac{54}{x}\right)$

Answer:

sin( -∅ )

- 1 / csc ( ∅ )

1 / csc ( -∅ )

Step-by-step explanation:

Since sin(x) is and odd function (a function where f(-a) = f(a) ).

-sin( ∅ ) = sin( -∅ )

On the other hand, we know that sin( ∅ ) = 1 / csc ( ∅ )

Another odd function, so the same as before applies.

-sin( ∅ ) = -1 / csc ( ∅ )

-sin( ∅ ) = 1 / csc ( -∅ )
