Given the expression
[tex]\:x^3+25\:[/tex]
Please note that the given expression could not factor further.
But, wait!
Let me take a sample expression and factor that sample expression so that you could get an idea of how to factorize the expression
Given the sample expression
[tex]x^2-5x+6[/tex]
Breaking the expression into groups
[tex]\:x^2-5x+6=\left(x^2-2x\right)+\left(-3x+6\right)[/tex]
Factor out x from x²-2x: x(x-2)
Factor out -3 from -3x+6: -3(x-2)
[tex]=x\left(x-2\right)-3\left(x-2\right)[/tex]
Factor out the common term (x-2)
[tex]=\left(x-2\right)\left(x-3\right)[/tex]
Thus, factorizing the expression such as:
[tex]x^2-5x+6=\left(x-2\right)\left(x-3\right)[/tex]

X+1 , 2x+3 and X+7 are the second, third and fourth terms of an arithmetic series. Find the value of X and hence calculate the common difference.
Answer:
x = 1,
Common Difference = -3
Step-by-step explanation:
Each number in series has the same difference, hence
(x + 1) - (2x+3) = (2x + 3) - (x + 7) Solve to find => x = 1Plug in value of x into (x+1) - (2x+3)Which solves for -3
Answer:
x=1

Pattern
dx/dy = - sin(x)
d^2/dx^2 = -cos(x)
d3/dx^3 = sin(x)
d4/dx^4 = cos(x)
So if you divide 107 by 4 what's the remainder?

The circumference of the base of a cone is 10π cm. The circumference of the base of a second similar cone is 20π cm. What is the ratio of the surface area of the first cone to that of the second cone?
Given:
The circumference of the base of a cone is 10π cm.
The circumference of the base of a second similar cone is 20π.
To find:
The ratio of the surface area of the first cone to that of the second cone.
Solution:
Let the radii of base of two cones are [tex]r_1[/tex] and [tex]r_2[/tex] respectively.
Circumference of the circular base is [tex]2\pi r[/tex], where, r is radius.
We have,
[tex]2\pi r_1=10\pi\text{ cm}[/tex]
[tex]r_1=\dfrac{10\pi}{2\pi}\text{ cm}[/tex]
[tex]r_1=5\text{ cm}[/tex]
And,
[tex]2\pi r_2=20\pi\text{ cm}[/tex]
[tex]r_2=\dfrac{20\pi}{2\pi}\text{ cm}[/tex]
[tex]r_2=10\text{ cm}[/tex]
It two cons are similar, then ratio of there areas is equal to square of the ratio of there corresponding dimensions, i.e., radius or heights.
[tex]\dfrac{A_1}{A_2}=\left(\dfrac{r_1}{r_2}\right)^2[/tex]
[tex]\dfrac{A_1}{A_2}=\left(\dfrac{5}{10}\right)^2[/tex]
[tex]\dfrac{A_1}{A_2}=\left(\dfrac{1}{2}\right)^2[/tex]
[tex]\dfrac{A_1}{A_2}=\dfrac{1}{4}[/tex]
The ratio form is
[tex]V_1:V_2=1:4[/tex]
Therefore, the ratio of the surface area of the first cone to that of the second cone is 1:4.
The ratio of the surface area of first cone to that of the second cone is; 1:4
Surface AreaFormula for the circumference of the base of a cone is;
C = 2πr
Where;
C is circumference
r is radius
Thus;
For the first cone;10π = 2πr
r = 10π/2π
r = 5
For the second cone;20π = 2πr
r = 20π/π
r = 10
Now, formula for surface area of the base is;
A = πr²
Thus, ratio of both area of first cone to second cone is;
A1/A2 = 5²/10²
A1/A2 = 25/100
A1/A2 = 1/4
Thus, ratio of first cone to that of the second cone is; 1:4

Answer:
B. 2:1, for every two yellow fish there is one orange fish
Step-by-step explanation:
So you have 6 yellow fish and 3 orange fish.
You can divide both these values by 3 to get:
2 yellow fish: 1 orange fish
Therefore, the simplified version of the ratio is 2:1
In context this means for every 2 yellow fish there is 1 orange fish.
The answer is then B.

Complete Question:
An object dropped from rest from the top of a tall building on Planet X falls a distance d(t)=13t^2 feet in the first t seconds. Find the average rate of change of distance with respect to time as t changes from t1=2 to t2=10. This rate is known as the average velocity, or speed.
The average velocity as t changes from 2 to 10 seconds is _______ feet/sec?
Answer:
[tex]v = 156[/tex]
Step-by-step explanation:
Given
[tex]d(t)=13t^2[/tex]
Time Interval: (a,b)
[tex]a = 2[/tex]
[tex]b = 10[/tex]
Required
Determine the average rate of change (v)
This is calculated as thus:
[tex]v = \frac{d(b) - d(a)}{b - a}[/tex]
Substitute values for b and a
[tex]v = \frac{d(10) - d(2)}{10 - 2}[/tex]
[tex]v = \frac{d(10) - d(2)}{8}[/tex]
Calculate d(10): Substitute 10 for t
[tex]d(t)=13t^2[/tex]
[tex]d(10) = 13 * 10^2[/tex]
[tex]d(10) = 13 * 100[/tex]
[tex]d(10) = 1300[/tex]
Calculate d(2): Substitute 2 for t
[tex]d(t)=13t^2[/tex]
[tex]d(2) = 13 * 2^2[/tex]
[tex]d(2) = 13 * 4[/tex]
[tex]d(2) = 52[/tex]
The equation [tex]v = \frac{d(10) - d(2)}{8}[/tex] becomes
[tex]v = \frac{1300 - 52}{8}[/tex]
[tex]v = \frac{1248}{8}[/tex]
[tex]v = 156[/tex]
Hence, the average rate of change is 156ft/s
