Answer:

domain= {x/x€R/x≠0}

Step-by-step explanation:

The domain of the equation y = 2/5x - 4 is all the real values of x.

Function is a combination of different types of variable and constants in which for the different values of x the value of function y is unique.

The given equation is,

y = 2/5x - 4.

The graph of the given equation is given below.

Since, the domain of the function is all the values of x,

For the given function, the values of x varies from -∞ to +∞.

Implies that, the value of x is the real value.

Therefore, the domain of the given equation is all real values.

Answer:

Largest: 800,499

Smallest: 799,500

The required largest number is 8,00, 499 and the smallest number is 7,99, 500.

Given that,
800,000 rounded to the nearest hundred thousand.
To determined the largest and smallest number.

What is rounding of values?

The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.

Here,
Any number range -500 and + 499 to 8,00,000 will be the smallest and largest number that could be rounded to 8,00,000.

smallest number  = 8,00,000 - 500 = 7, 99, 500

largest number = 8,00,000 + 499 = 8,00,499

Thus, the required largest number is 8,00, 499 and the smallest number is 7,99, 500.

Answer:

[tex]2.5\; \rm m^3[/tex].

Step-by-step explanation:

Let [tex]V_1[/tex] and [tex]P_1[/tex] denote the volume and pressure of this gas before the change. Let [tex]V_2[/tex] and [tex]P_2[/tex]denote the pressure of this gas after the change.

The ratio between the volume of this gas before and after the change would thus be [tex]\displaystyle \frac{V_1}{V_2}[/tex].

The ratio between the pressure of this gas before and after this change would be [tex]\displaystyle \frac{P_1}{P_2}[/tex].

Because the volume of a given mass of (ideal) gas varies inversely with pressure, these two ratios should be reciprocal of each other. That is:

[tex]\displaystyle \frac{V_1}{V_2} = \frac{1}{\displaystyle \displaystyle \left(\frac{P_1}{P_2}\right)}[/tex].

In other words:

[tex]\displaystyle \frac{V_1}{V_2} = \frac{P_2}{P_1}[/tex].

Rearrange and solve for [tex]V_2[/tex], the volume of this gas after the change:

[tex]\displaystyle V_1 = V_2\cdot \left(\frac{P_2}{P_1}\right)[/tex].

[tex]V_2 = \displaystyle V_1 \cdot \left(\frac{P_1}{P_2}\right)[/tex].

From the question:

Solve for [tex]V_2[/tex]:

[tex]\begin{aligned} V_2 &= V_1 \cdot \left(\frac{P_1}{P_2}\right) \\ &= 2\; \rm m^3 \times \frac{500\; \rm N \cdot m^{-2}}{400\; \rm N \cdot m^{-2}} = 2.5\; \rm m^3\end{aligned}[/tex].

Answer:

4 inches

Step-by-step explanation:

hi! so there are 64 cubes with 1 inch side lengths. if we are trying to fill a container which is the size of a cube, we must take the cube root of 64, which is 4. this is because 4*4*4 is 64, and we are using cubes to fill up a larger cube. this means that there are going to be 4 1-inch cubes on each side of the larger cube. when filling this up, the volume is 64 cubic inches, which makes sense because of the 64 smaller 1-inch cubes. im not 100% sure by what you mean by "edge length", but if it is the normal length of the cube, the answer is 4 inches because the cube root of 64 is 4. however, if you are talking about the diagonal from edge to edge, you have to split up a 4 by 4 square into two congruent triangles by putting a diagonal line down the middle, and use the pythagorean theorem to find the length of the diagonal.

4^2+4^2=c^2

16+16=sqrt 32

sqrt 32

if this is the case, sqrt 32 inches is the answer.

Answer:

Convergent

Step-by-step explanation:

This is an alternating series where bn = 2n / eⁿ.  Apply the alternating series test:

lim(n→∞) bn

= lim(n→∞) (2n / eⁿ)

Use L'hopital's rule:

= lim(n→∞) (2 / eⁿ)

= 0

For n ≥ 1, the series is decreasing. 2(n+1) / eⁿ⁺¹ < 2n / eⁿ.

Therefore, the series converges.

Hi There!

Your answer is:

Alyssa ran 2 and a half miles if she ran 2/3rds of the loop.

Step-by-step explanation:

1 loop= 3 & 3/4ths miles

WE NEED: 2/3rds of a loop

1 loop/ 3 = 3& 3/4ths miles /3

CHANGE MILES TO IMPROPER FRACTION!

1/3 loop = 15/4ths divided by 3

Multiply 15/4ths by the inverse of 3

15/4ths * 1/3 = 15/ 12

SIMPLIFY

1 & 3/12 or 1& 1/4

1/3loop = 1 & 1/4th mile

To get 2/3rds loop, multiply both sides by 2

2/3rds loop = 2 & 1/2 Miles
