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:

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:

646.0 and 0.1 but you might have to keep the second one the same .125

Step-by-step explanation:

The nearest tenth is the number behind the decimal, and the number in the hundredths place is what you use to see if where to round it. If it is 4 or less keep it the same it it is 4-9 change is up by one.

EX: 1.58  you would round it to 1.6 because the number in the hundredths place is bigger than 4 so you up the number in the tenths place one.

The product of 645.99 and 0.125 would be 80.7 which is rounded to the nearest tenth.

The decimal point is followed by the number that is closest to the tenth, and the hundredth place number is used to determine whether or not to round the number. If it is four or fewer, leave it alone; if it is four to nine, move it up one.

We have to determine the product of 645.99 and 0.125

⇒ 645.99 × 0.125

⇒ 80.74875

Rounded to the nearest tenth, we get

⇒ 80.7

You would diminish the number in the tenth place by one because the number in the hundredth place is less than 5, thus you would round it to 80.7.

Therefore, the product of 645.99 and 0.125 would be 80.7 which is rounded to the nearest tenth.

Answer:

The range of the function is [-∞,6]

Step-by-step explanation:

Range of a Function

It's the set of values the function takes when x moves into the function's domain.

It can be graphically determined by placing imaginary horizontal lines from minus infinite to plus infinite. Where the line meets the function, that value of y belongs to the range.

The given function is:

[tex]f(x)=-x^2+6x-3[/tex]

Using a graphing tool, we draw the graph shown in the image below.

It can be clearly seen that if we imagine horizontal lines from above y=6 to infinity, they won't ever touch the graph of the function. From y=6 and below, every horizontal line will touch the function one time or twice.

We can conclude the range of the function is [-∞,6]

Step-by-step explanation:

The spread between the maximum and minimum is almost 1/3 of the average of those values (0.8 vs 2.6). We expect repeated measurements of the same physical value to be well within 5% of their mean if they are done carefully.

Answer:

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
