Answer: C. 24x⁴ - 12x³

Step-by-step explanation:

The area of a rectangle is length × width.

4x² × (6x²– 3x) to answer this, we multiply 4x² for each term inside the parentheses.

4x² × 6x² = 24x⁴ (4 × 6 = 24 and x² × x² = x⁴)

4x² × -3x = -12x³ (4 × -3 = -12 and x² × x = x³)

So the answer is 24x⁴ - 12x³

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the

kenny6666 [7]

Given:

The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation

$y=-29x^2+1388x-10040$

To find:

The maximum amount of profit the company can make, to the nearest dollar.

Solution:

If a quadratic equation is $f(x)=ax^2+bx+c$ , then the vertex is

$Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)$

If a>0, then vertex is the minimum point and if a<0, then the vertex is the maximum point.

We have,

$y=-29x^2+1388x-10040$

Here, $a=-29,b=1388, c=-10040$ . Clearly, a<0. So, the vertex is the point of maxima.

$-\dfrac{b}{2a}=-\dfrac{1388}{2(-29)}$

$-\dfrac{b}{2a}=-\dfrac{1388}{-58}$

$-\dfrac{b}{2a}\approx 23.931$

Putting x=23.931 in the given equation, we get

$y=-29(23.931)^2+1388(23.931)-10040$

$y=-16608.09+33216.228-10040$

$y=6568.138$

The vertex is at (23.931,6568.138).

Therefore, the maximum profit is $6568.138 when x=23.931.

(time limit!) what is the volume below? A) 112 B) 224 C) 784 D) 896

Radda [10]

To find a volume of a cylinder we use the following formula:
$v = \pi {r}^{2} h$
Plug in the values:

$v = \pi \times {8}^{2} \times 14$
Take the square:
$v = \pi \times 64 \times 14$
Multiply the numbers:
$v =896 \pi {m}^{2}$
