rodikova [14]3 years ago
7 0

3999991=4000000-9=2,000^2-3^2=(2000-3)(2000+3)=1997\cdot2003

As we can see, the number 3999991 can be expressed as a product of two numbers that are not 1 and the number 3999991 itself, therefore that number is not prime.

Find the value of x for which the graph of y = 3x^2 - 8x + 7 achieves its minimum y-value.​
gulaghasi [49]

Answer:

<h3>The y value achieves its minimum at x = 4/3</h3>

Step-by-step explanation:

Given the graph of y to be 3x² - 8x + 7, to get the value of x for which the graph function achieves its minimum y value, we need to find its turning point first.

At the turning point, dy/dx = 0

Given y = 3x² - 8x + 7

\frac{dy}{dx} = 6x-8\\ at\ turning\ point\ 6x-8 = 0

6x = 8\\x = \frac{8}{6}\\ x =\frac{4}{3}

The y value achieves its minimum at x = 4/3

Priya's rectangular prism measures inches by inches by 2 inch.
dedylja [7]

The number of cubes with edge length ⅕ inch that will fit in the prism is: 1,920 cubes

<h3>Volume of a Rectangular Prism</h3>

Volume of a rectangular prism = length × width × height

<h3>Volume of a Cube</h3>

A cube has equal edge length. Therefore, the volume of a cube = a³, where a is the edge length.

Given the following,

Dimensions of Priya's Rectangular Prism:

2⅖ = 2.4 inches

3⅕ = 3.2 inches

2 inches

Volume of the Rectangular Prism = 2.4 × 3.2 × 2 = 15.36 in.³

Dimension of the cubes:

edge length = ⅕ inch

Volume of the cube = (⅕)³ = 0.008 in.³

The number of ⅕ inch edge cube that will fit in the prism = Volume of Prism / Volume of Cube

= 15.36/0.008 = <em>1,920 cubes </em>
