Answer:
The probability of the number cube showing a 3 = 0.1667
Step-by-step explanation:
A number cube with the numbers 1 through 6 is rolled.
So, The numbers which are marked on the cube : 1, 2, 3, 4, 5, 6
Total no. of numbers which are marked on the number cube = 6
No. of times the number cube is rolled = 1
We need to find the theoretical probability, as a decimal, of the number cube showing a 3.
Therefore, The probability of the number cube showing a 3 is given by :

The length of rectangle B is 25% greater than the length of rectangle A. The width of rectangle B is 3/5 X the width of rectangle A. Find the fraction Area of B/Area of A Give your answer in its simplest form.
Answer:
The value of Area of B/Area of A is 0.75.
Step-by-step explanation:
It is provided that:
The length of rectangle B is 25% greater than the length of rectangle A. The width of rectangle B is 3/5 X the width of rectangle A.Consider the diagram below.
The area of a rectangle is:
[tex]\text{Area}=\text{Length}\times \text{Breadth}[/tex]
Compute the area of rectangle A as follows:
[tex]\text{Area of A}=l\times b[/tex]
Compute the area of rectangle B as follows:
[tex]\text{Area of B}=1.25\ l\times \frac{3}{5}\ b=0.75\ (l\times b)[/tex]
Compute the value of Area of B/Area of A as follows:
[tex]\frac{\text{Area of B}}{\text{Area of A}}=\frac{0.75\ (l\times b)}{l\times b}=0.75[/tex]
Thus, the value of Area of B/Area of A is 0.75.
6w-19 + k when
w=8 and k = 2
Answer:
31.
Step-by-step explanation:
1. Write out the problem.
6w-19 + k; w=8 and k=2
2. Figure out the first part of the problem.
So, if w=8 and 6 and w are next to each other, we should multiply 6*8, which is 48. Next, it says to subtract 19. 48-19=29.
3. Find out what the last part of the problem is.
Since the first part of the problem is 29 and k=2, we should add 29+2=31, which is the final answer.

What is the logarithmic function?In mathematics, the logarithmic function is an inverse function to exponentiation. The logarithmic function is defined as
For x > 0 , a > 0, and a ≠1,
y= logₐ x if and only if x = a^y
Then the function is given by
f(x) = logₐx
Given here log x= 3 ⇒x=10³

find a polynomial f(x) of degree 3 with real coefficients and the following zeros. 4, 2-1
Answer:
[tex]P(x)=x^3-5x^2+2x+8[/tex]
Step-by-step explanation:
If the polynomial has the following zeros: x= 4, x=2, and x=-1, then it must have the following factors which guarantee the polynomial will render zero at the given points:
[tex]P(x)=C (x-4)\, (x-2) \,(x+1)[/tex]
where C is any multiplicative constant. Since there is no other condition imposed on the polynomial, we can adopt a simple constant C = 1 to facilitate our final calculation of writing the polynomial in standard form:
[tex]P(x)=(x-4)\, (x-2) \,(x+1)\\P(x)=(x^2-2x-4x+8)\,(x+1)\\P(x)= (x^2-6x+8)\,(x+1)\\P(x)=x^3+x^2-6x^2-6x+8x+8\\P(x)=x^3-5x^2+2x+8[/tex]

If x, y, and z are positive integers such that 6xyz+30xy+21xz+2yz+105x+10y+7z=812, find x+y+z.
Answer:
[tex]x+y+z \Rightarrow 2+2+6 = 10[/tex]
Step-by-step explanation:
First we have to factor the equation:
[tex]6xyz+30xy+21xz+2yz+105x+10y+7z=812[/tex]
The commom factor of first three terms and [tex]105x[/tex] is [tex]3x[/tex]. Note that [tex]105x=3x(35)[/tex]
[tex]3x(2yz+10y+7z+35)+2yz+10y+7z=812[/tex]
[tex]3x(2yz+10y+7z+35)+(2yz+10y+7z)=812[/tex]
In order to have two equal factors add 35 both sides:
[tex]3x(2yz+10y+7z+35)+(2yz+10y+7z+35)=847[/tex]
Let's factor [tex](2yz+10y+7z+35)[/tex]
[tex](2yz+10y+7z+35) \Rightarrow 2y\left(z+5\right)+7\left(z+5\right) \Rightarrow \left(z+5\right)\left(2y+7\right)[/tex]
Now we have:
[tex]3x(z+5)\left(2y+7\right)+\left(z+5\right)\left(2y+7\right)=847[/tex]
[tex](3x + 1) (2y + 7) (z + 5) = 847[/tex]
Now it is the interesting part: You have to figure out that 3 numbers multiplied by each other will result in 847.
We have [tex]847 = 7 \cdot 11 \cdot 11[/tex]
Let's try
[tex]2y+7=7\\2y=0[/tex]
I will stop right here. This is not true.
Let's try then
[tex]2y+7=11\\2y=4\\y=2[/tex]
Now let's try
[tex]z+5 = 11\\z=6[/tex]
Now let's try
[tex]3x+1=7\\3x=6\\x=2[/tex]
Note that in this case I didn't considered [tex]3x+1=11[/tex] because it would not be an integer.
Therefore,
[tex]x+y+z \Rightarrow 2+2+6 = 10[/tex]

The area of rectangle ABCD is 9 cm2 show that x2 +5x=3
Answer: x² + 5x = 3
Step-by-step explanation:Step-by-step explanation:
The rectangle has been divided into a square and three rectangles.
The area of
a square = (x)(x) = x²
a rectangle #1 = (2)(x) = 2x
a rectangle #2 = (3)(x) = 3x
a rectangle #3 = (2)(3) = 6
The area of a large rectangle is the sum of the square area and three rectangles, and is 9 cm². Therefore we have the equation:
x² + 2x + 3x + 6 = 9 subtract 6 from both sides
x² + 5x + 6 - 6 = 9 - 6
x² + 5x = 3
The equation is proven.
What is an area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
The rectangle has been divided into a square and three rectangles.
The areas are;
square = (x)(x) = x²
rectangle 1 = (2)(x) = 2x
rectangle 2 = (3)(x) = 3x
rectangle 3 = (2)(3) = 6
The area of a large rectangle is the sum of the square area and three rectangles, and is 9 cm². Therefore, we have the equation:
x² + 2x + 3x + 6 = 9
x² + 5x + 6 - 6 = 9 - 6
x² + 5x = 3
Hence, proved.

f(x) = x² - 81 = ( x+ 9)(x - 9) Difference of two squares
g(x) = x+9/x-9
g(x) . f(x) = x + 9/ x - 9 × (x+9)(x - 9)
