There are three different whole numbers are factors of 2020.
What is Prime factorization ?
Prime factorization is defined as a way of finding the prime factors of a number, such that the original number is evenly divisible by these factors. As we know, a composite number has more than two factors, therefore, this method is applicable only for composite numbers and not for prime numbers.
Prime factors of 2020 = 2,2,5,101
different whole numbers are = 2,5,101
As these three numbers are prime numbers, these are the different whole numbers for 2020.
Therefore, there are three different whole numbers are factors of 2020.

Solve for the following equation . x^6-9x^3+10=0
Answer:
x = ∛10x = -∛10/2 +(∛10√3)/2ix = -∛10/2 -(∛10√3)/2ix = -1x = 1/2 -(√3)/2ix = 1/2 +(√3)/2iStep-by-step explanation:
You want to solve the 6th-degree equation x^6 -9x^3 +10 = 0.
QuadraticThe equation is basically quadratic in x^3. Substituting z = x^3, we have ...
z^2 -9z +10 = 0
(z -10)(z +1) = 0 . . . . . factored form
z = 10, z = -1 . . . . . . . values of z that make the factors zero
CubicsNow, we have two cubic equations to solve:
x^3 = 10 ⇒ x = ∛10x^3 = -1 ⇒ x = ∛(-1) = -1The real root is given by the cube root function. The imaginary roots are that value multiplied by 1∠±120° = (-1/2 ±(√3)/2i). Then the six roots are ...
x = ∛10x = -∛10/2 +(∛10√3)/2ix = -∛10/2 -(∛10√3)/2ix = -1x = 1/2 -(√3)/2ix = 1/2 +(√3)/2i__

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.From the points, we have that:

Composition of transformationsThe composition ...
[tex]T_{-3,-1}\circ r_{\text{x-axis}}[/tex]
is interpreted to mean reflection in the x-axis occurs first, then translation by (-3, -1).
That is, a composition of transformations is evaluated right to left.
ReflectionReflection in the x-axis moves a point from below the x-axis to the same distance above the x-axis. That is, the sign of the y-coordinate changes:
(-4, -6) ⇒ (-4, 6) . . . reflection in the x-axis
TranslationThe translation vector is added to the coordinates of the point:
(-4, 6) +(-3, -1) = (-4-3, 6-1) = (-7, 5)

What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
In item a, the vertex is at (-6,-2), hence:
f(x) = a(x + 6)² - 2
When x = -8, f(x) = -6, hence we use it to find a as follows:
-6 = 4a - 2
4a = -4
a = -1.
Hence:
f(x) = -(x + 6)² - 2.
In item b, the vertex is at (6,2), hence:
g(x) = a(x - 6)² + 2
When x = -2, g(x) = 4, hence we use it to find a as follows:
4 = 64a + 2
64a = 2

Using the concept of linear equation we can conclude that the number of marbles sold by Mark is 23 and the number of marbles sold by Don is 72.
What is a linear equation?An equation is said to be linear if the highest power of the variable is 1. It is also called as one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variable is x and A is the coefficient of x, while B is a constant.
Let the number of marbles Mark sells be ‘x’
then, the number of marbles Don sells can be given by ‘3x+3’
Total number of marbles sold=95
We can for equation by adding the number of marbles Mark sells and the number of marbles Don sells to the total number of marbles sold. The equation formed is
x+3x+3=95
4x+3=95
4x=95-3
4x=92
x=23
The number of marbles Mark sells =23
Number of marbles Don sells=3x+3
Substituting value of ‘x’
Number of marbles Don sells=(3×23)+3
Number of marbles Don sells=69+3
Number of marbles Don sells=72

The hotel should order 39000 bars of soap if the hotel goes through on an average of 750 soaps each week.
In everyday terms, an average is one number chosen to represent a list of numbers; it is often the sum of the numbers divided by the number of numbers in the list (the arithmetic mean).
Average is calculated by dividing the sum of the data by the frequency of the data.
Average=sum ÷ frequency
For example if the average of the data set {1,2,3,5,10}=(1+2+3+5+10)÷5=21÷5=4.2
Now for the given question average is given as 750 bars of soap.
We know that there are 52 weeks in a year. ∴ frequency=52
Hence sum of all the averages will give the total number of soap ordered by the hotel in a year.
Sum=average × frequency
or, sum=750 × 52
