The value of 8 cube 512

As we know the cube of a number is the value that are obtained when a number is multiplied by itself three times.

If n be any real valued number then the cube of p is the product of number n  three times.

i.e., n × n × n

The cube of number is represented by the third power (exponent = 3) of that number.

For above the cube of number 'n' is represented by n³

Here we need to find the cube of number 8.

From definition of cube of number,

8³ = 8 × 8 × 8

8³ = 64× 8

8³ = 512

Thus the cube of number 8 = 512

The product of two sets is the set of ordered pair of elements from each set.

We know that the set is nothing but the collection of well-defined objects or elements or numbers.

The elements of sets are written in the curly brackets, seperated by comma.

A set is represented by a capital letter symbol.

For example., the set of natural numbers is denoted by N.

N = {1, 2, 3, 4, . . .}

As we know the Cartesian Product of sets M and N is defined as the set of all ordered pairs (x, y) such that x belongs to set M and y belongs to set N.

It is denoted as M × N = {(x,y) | x ∈ M and y ∈ N}

For example, consider a set P = {1, 2}

and set M = {3, 4, 5},

From the definition of the Cartesian Product of P and M,

Answer:

  y = 900(0.91^t)

Step-by-step explanation:

You want a function that describes the value of a $900 sound system that decreases in value by 9% per year.

When the amount of change is proportional to the amount, the amount is described by an exponential function:

  y = ab^x

where 'a' is the initial value, and 'b' is the "growth factor."

Here, the change is expressed as a "growth rate" of -9% per year. The growth factor is 1 added to the growth rate:

  b = 1 +(-9%) = 1 -0.09 = 0.91

The initial value is given as ...

  a = 900

So the function you want is ...

  y = 900(0.91^t)

__

Additional comment

The independent variable in this case is time, and the problem statement tells you to use 't' to represent it. The decay rate is given as a percentage per year, so the units of t will be years.

What is the solution to an equation?

In order to make the equation's equality true, the unknown variables must be given values as a solution. In other words, the definition of a solution is a value or set of values (one for each unknown) that, when used as a replacement for the unknowns, transforms the equation into equality.

Vertical angles are equal

2x+1=53

=> 2x=53-1 = 52

x=52/2 = 26 degrees

similarly,

5x+1=66

D) The term "imaginary roots" describes the roots of the equation 3x2 - 4x + 5 = 0 the best.

The formula is the quadratic equation ax2 + bx + c = 0 in standard form.

x = [-b ± √(b2 - 4ac)]

/ 2a

It follows that

3x2 - 4x + 5 = 0

Here, an equals 3, b equals -4, and c equals 5.

Using these numbers as replacements in the formula

x = [-(-4) ± √((-4)2 - 4 × 3 × 5)]

/ (2 × 3)

By even more simplifying

x = [4 ± √(16 - 60)]

/6

x = [4 ± √-44]/ 6

As a result,

x = [4 ± 2√-11]/ 6

x = [2 ± I √11]/ 3

Additionally, b2 - 4ac = -44 0 is the discriminant. So, we have invented roots.

The ant population increases by factor of 5 every week. After 3 weeks, there will be 800 ants in the farm.

The problem can be solved by considering the ant population growth as a geometric sequence.

In a geometric sequence, a term is obtained by multiplying the previous term by a constant, which is called a common ratio. We can consider this common ratio as a growth factor.

In this case, the common ratio = 5

week 1 = 32 ants

week 2 = 32 x 5 ants = 160 ants

week 3 = 160 x 5 ants = 800 ants

We can also find the number of ants using the geometric sequence formula for the nth term:

a(n) = a . rⁿ⁻¹

Where:

a = first term = 32

r = common ratio = 5

Hence,

a(3) = 32 x 5² = 800 ants

Assume that log₂(7) is rational. This means that it can be written as the ratio of two integers, a/b, where a and b are integers and b is not equal to zero.

Then, using the definition of a logarithm, we have: 2^(a/b) = 7

Multiply both sides by b, we have: 2^a = 7b

Now we have a problem, because 7b is not necessarily a power of 2. This means that our assumption that log₂(7) is rational leads to a contradiction, and therefore log₂(7) must be irrational.

What is the price of an item after a 30% discount if the original price of the item is 56 dollars?

We know that the average price of a gallon of milk in 2000 was $2.78 and that it increased by about $0.11 per year. To find the years in which the price of a gallon of milk is between $3 and $4, we can use the following inequality:

2.78 + 0.11y < x < 4

Where x is the price of a gallon of milk in a given year y, and y represents the number of years since 2000.

The inequality can also be written as:

2.78 + 0.11y < x < 4

That can be simplified as

y > (3-2.78) / 0.11 = (0.22) / 0.11 = 2

y < (4-2.78) / 0.11 = (1.22) / 0.11 = 11

So, the years in which the price of a gallon of milk is between $3 and $4 are y > 2 and y < 11

1st purchase     5                8            $20.25

2nd purchase    1                3              $6.50

Let the cost of bottles of water = b and the cost of slices of pizza = p

Equation 1: 5b + 8p = 20.25

Equation 2: b + 3p = 6.50

Multiply Equation 2 by 5:

Equation 3: 5b + 15p = 32.50

Subtract Equation 1 from Equation 3:

5b + 15p = 32.50

-

5b + 8p = 20.25

7p = 12.25

p = 1.75

The cost of one slice of pizza (p) = $1.75

Check:

b + 3p = 6.50

b + 3(1.75) = 6.50

b + 5.25 = 6.50

any negative exponent of 1.3 means we have to consider it as 1/1.3 with the positive exponent.

so, if the given temperature (x) is negative, 1.3 has a positive exponent and gets bigger and bigger the lower (smaller) x gets.

if the given temperature (x) is positive, 1.3 has a negative exponent and gets smaller and smaller the higher (bigger) x gets.

the domain is the interval or set of all valid x-values.

there is no need for any restriction for x.

so, the domain is all real numbers.

the question is : up to what temperature will there be heating ?

at 5°C ? yes, sure.

at 10°C ? yes, sure.

at 15°C ? some people still need heating.

at 20°C ? most likely not.

but f(20) = $0.042094266... ≈ $0.04

so, still a tiny little bit of heating is happening for the function, but in reality most likely not at all.

the information about such a limit is missing in the question. so, again no limit for x.

f(-8) means that x = -8.

f(-8) = 8(1.3)^--8 = 8(1.3)⁸ = 8×8.15730721 =

The linear equation perpendicular to the line y = 1/2x - 4 is:

y = -2x + 25

A general linear equation can be written as:

y = m*x + b

Where m is the slope and b is the y-intercept.

And two lines are perpendicular if the product between the slopes is -1, then if we want to find a line perpendicular to:

y = 1/2x - 4

Then the slope m must be sch that:

m*(1/2) = -1

m = -2

Then the line is like:

y = -2*x + b

And we know that this passes through (10, 5), replacing these values:

5 = -2*10 + b

5 = -20 + b

5 + 20 = b
