Answer:

486√3 ft² ≈ 841.8 ft²

Step-by-step explanation:

The area of a regular hexagon with side length s is ...

A = (3√3)/2s²

For the side length of 18 ft, the area is ...

A = (3√3)/2(18 ft)² = 486√3 ft² ≈ 841.8 ft²

Identify the vertex for the graph of y = −2x2 − 12x 1.

RUDIKE [14]

Answer: (-3,19)

Step-by-step explanation:

Here the given function is,

$y = -2x^2-12x+1$

$\implies y = -2(x^2+6x)+1$

$\implies y = -2(x^2+6x)+1+18-18$

$\implies y = -2(x^2+6x+9)+19$

$\implies y = -2(x+3)^2+19$

$\implies y = -2(x-(-3))^2+19$

Since, the standard equation of a quadratic function is $y = a(x - h)^2 + k$

Where (h,k) is the vertex of the function.

On comparing the equation of given function with this standard form,

We get, the vertex of the given function is (-3,19)

⇒ First option is correct.

If, in a monopoly market, the demand for a product is p = 185 − 0.10x and the revenue function is r = px, where x is the number

never [62]

Answer:

The price that'll maximize revenue is $p=92.5$

Step-by-step explanation:

We know that the revenue function is $r = px$ where <em>x</em> is the number of units sold and <em>p</em> is the demand function given by $p = 185 - 0.10x$ .

Therefore,

$r = px \\r=(185 - 0.10x)x\\r=185x-0.1x^2$

The maximums of a function are detected when the derivative is equal to zero so, to find what value of x maximizes the revenue function, we must find the derivative of the revenue function ( $\frac{dr}{dx}$ ) and set it equal to 0.

$\frac{d}{dx} r=\frac{d}{dx} (185x-0.1x^2)\\\\\frac{d}{dx} r=\frac{d}{dx}\left(185x\right)-\frac{d}{dx}\left(0.1x^2\right)\\\\\frac{d}{dx} r=185-0.2x$
