The graph shows how the volume, V, of the cube changes as the length of the sides, S, changes
Artemon [7]

Solution:

The graph shows how the volume, V, of the cube changes as the length of the sides, S, changes.

On analysing the graph ,

\left\begin{array}{ccc}s&v\\0&0\\2&1\\4 &8\end{array}\right

This table shows how the volume, V, of the cube changes as the length of the sides, S, changes.

Option C is the correct option for the table that matches the graph.

An equation in point slope form (2,1) and has a slope of m=2
Svet_ta [14]

Answer:

y=2x-3

Step-by-step explanation:

<em>Since we know that the slope-intercept form is </em><em>y=mx+b</em><em>, we can plug in the formula with what we already know to find b!</em>

<em>In the coordinates (2,1): </em>

  • 2 is the x
  • 1 is the y

<em>Now, we will plug these numbers in:</em>

1=2*2+b

1=4+b

b=-3

<em>Now we can rewrite the equation since we found b:</em>

y=2x-3

Hope this helped! :)

Alan needs to manufacture a circular metal plate with a perimeter of `10pi` centimeters. If the allowed error tolerance in the p
AnnZ [28]

The ideal radius Alan must control is \frac{1}{2\pi } cm.

<h3>Define perimeter of circle.</h3>

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The area of a circle determines the space it takes up. A circle's diameter is equal to the length of a straight line traced through its center. Usually, it is stated in terms of units like cm or m.

Given data -

Perimeter of circular plate = 10\pi cm

We know that perimeter of a circle is 2\pir

Therefore   10\pi = 2\pir

r = 5 cm

The given error Alan can make is +-1 cm.

Minimum radius is given by

2\pir = 10\pi - 1

r = \frac{10\pi - 1 }{2\pi }

r = 5 - \frac{1}{2\pi }

Maximum radius is given by

2\pir = 10\pi + 1

r = \frac{10\pi + 1 }{2\pi }

r = 5 + \frac{1}{2\pi }

The ideal radius Alan must control is \frac{1}{2\pi } cm.

The number of customers for a new online business can be modeled by y = 8x2 + 100x + 250, where x represents the number of month
kenny6666 [7]
The best prediction for the number of customers is 5450.

To find this value, you just need to plug in 20 for x into the expression. Then, evaluate it using the order of operations.

8(20)^2 + 100(20) + 250
8(400) + 100(20) + 250
3200 + 2000 + 250
5450
