perfect square trinomial conditions
Step-by-step explanation:
step 1. an example of difference of squares (dos) is (x + y)(x - y) = x^2 - y^2.
step 2. dos must have only 2 square rootable terms and a "-" between them.
step 3. 196x^2 - 121y^2 = (14x + 11y)(14x - 11y) works!
step 4. 5x^2 - 245 = 5(x^2 - 49) = 5(x + 7)(x - 7) works!
step 5. 27w^5 - 75w = 3w(9w^4 - 25) = 3w(3w^2 + 5)(3w^2 - 5) works!
step 6. x^4 - 100y^2 = (x^2 - 10y)(x^2 + 10y) works!

On the number line, which point is the closest pi .
A.
B.
C.
D.
The closest point to the number line is C.
Hence Option C is correct.
In the given number line
There are 10 equidistant points between 3.1 and 3.2
So, the set of points shown on the line is,
{3.1, 3.11, 3.12, 3.13, 3.14, 3.15, 3.16, 3.17, 3.18, 3.19, 3.2}
Therefore,
Point c represents point 3.14 approximately.
Since we know that π is an irrational number,
So it is non-terminating and non-repeating but for approximation,
π = 22/7
π ≈ 3.142
Hence,
The point C is very close to the π.

Cuatro meses después que se detuviera la publicidad, una compañia fabricante notifica que sus ventas han caido de 100.000 unidades por mes a 80.000. Si las ventas siguen un patron de decrecimiento exponencial, cuantas unidades habra despues de los siguientes dos meses?
Answer:
51,200 unidades
Step-by-step explanation:
Paso 1
Calculamos el porcentaje de disminución
= 100000 - 80000/100000 × 100
= 20000/100000 × 100
= 20%
Por lo tanto, el porcentaje de disminución cada mes = 20%
Paso 2
La fórmula de la disminución exponencial
y = a (1 - r) ^ t
a = 80.000
r = 20% = 0,2
t = tiempo en meses = 2
y = 80000 (1 - 0,2) ^ 2
y = 51.200 unidades
Usando una función exponencial, se encuentra que habra 71.554 unidades despues de los siguientes dos meses.
Una función exponencial decreciente tiene el siguiente formato:
[tex]A(t) = A(0)(1 - r)^t[/tex]
En que:
A(0) es la cuantia inicial.r es la tasa de desintegración.En este problema:
Inicialmente, 100000 unidades por mes, o sea, [tex]A(0) = 100000[/tex].Cuatro meses después, 80000 unidades por mes, o sea, cuando [tex]t = 4, A(t) = 80000[/tex], e esto es usado para encontrar r.[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]80000 = 100000(1 - r)^4[/tex]
[tex](1 - r)^4 = 0.8[/tex]
[tex]\sqrt[4]{(1 - r)^4} = \sqrt[4]{0.8}[/tex]
[tex]1 - r = 0.945742[/tex]
Por eso:
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]A(t) = 100000(0.945742)^t[/tex]
Apos el siguinte dos meses, hay el mes 6, por eso:
[tex]A(6) = 100000(0.945742)^6 = 71554[/tex]
Habra 71.554 unidades despues de los siguientes dos meses.

Answers:
Have a common difference Have a common factor Have a linear first difference============================================================
Explanation:
Linear functions, such as y = 2x+5, have a common difference. In that example, the common difference would be 2 since we add 2 to each term to get the next one. Consider when x = 1 and that leads to y = 7. Then when x = 2, we have y = 9. Then when x = 3, we have y = 11, and so on. The sequence of y values {7,9,11,...} shows we add 2 each time.
------------------
Exponential functions have us multiply the previous term by some common factor to get the next term. A sequence like {2,6,18,...} has us multiply by 3 each time and the exponential function modeling this sequence is y = 2(3)^(x-1) where x is a natural number. So this is an example showing that exponential functions have a common factor, or we can call this a common ratio.
------------------
Quadratic functions are a bit strange.
Let's consider the quadratic of y = x^2. The sequence of y values it generates is {1,4,9,16,25...} for positive integers x = 1, 2, 3, 4, 5....
Let's subtract the adjacent terms (larger - smaller)
4-1 = 39-4 = 516-9 = 725-16 = 9Note the results of 3,5,7,9 are in a linear sequence (we're adding 2 to each increment value, so the next increment would be +11). We can consider this a linear first difference.
------------------
For any of these functions, I'm restricting x to be an integer and x = 1 is the smallest input possible.

In ∆ABC,
∠A = 60°∠B = 60°BC = 12 units∠BDC = 90°To Find :Area of ∆ABC = ?Solution :As, we have :
∠A = 60°∠B = 60°So, By angle sum property of triangle :
∠A + ∠B + ∠C = 180°
[tex] \tt : \implies 60\degree + 60\degree + \angle C = 180\degree[/tex]
[tex] \tt : \implies 120\degree + \angle C = 180\degree[/tex]
[tex] \tt : \implies \angle C = 180\degree - 120\degree[/tex]
[tex] \tt : \implies \angle C = 60\degree[/tex]
Now, we have :
∠A = 60°∠B = 60°∠C = 60°As, all angles are of same length, therefore it is a equilateral triangle.
We know that sides of equilateral triangle are equal.
[tex] \tt : \implies AB = BC = AC[/tex]
Now, we have BC = 12 units.
Hence, all sides are of 12 units.
Now, we know that area of equilateral triangle is :
[tex] \large \underline{\boxed{\bf{Area_{(equilateral \: triangle)} = \dfrac{\sqrt{3}}{4} side^{2}}}}[/tex]
[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{4} \times (12 \: units)^{2}[/tex]
[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{\cancel{4}} \times \cancel{144} \: units^{2}[/tex]
[tex] \tt : \implies Area = \sqrt{3} \times 36 \: units^{2}[/tex]
[tex] \tt : \implies Area = 36\sqrt{3} units^{2}[/tex]
So, Area of given triangle is 36√3 units².
Is y=x^2+7 a linear equation?
Answer:
No, it is not a linear equation
Step-by-step explanation:
This equation contains the term x², meaning that it is a quadratic function (parabola)
So, it is not a linear equation.
If it were a linear equation, x would not be squared, and the equation would have been in y = mx + b form.
The answer is no, it is not a linear equation.
Answer:
Given :-[tex] \large \sf \bullet \: y = {x}^{2} + 7[/tex]
To Find :-Is it a linear Equation
Solution :-We may notice that
x has power as 2.
So,
We know that
A linear Equation doesn't consist of power. Linear equation only consist of variable and constant.
No,

Find the sum of the first 33 terms of the following series, to the nearest
integer.
2,8, 14, ...
Answer:
3234
Step-by-step explanation:
The series is arithmetic with a common difference = d = 6
First we need to find the 33rd term. Use the formula [tex]a_{n} = a_{1} + (n - 1)d[/tex] where n = 33 and [tex]a_{1} = 2[/tex]
[tex]a_{33} = 2 + (33 - 1)6 = 2 + 32(6) = 194[/tex]
Now the formula for the sum of an arithmetic series is [tex]S_{n} = \frac{n(a_{1} + a_{n} )}{2}[/tex]
So, [tex]S_{33} = \frac{33(2 + 194)}{2}[/tex]
= [tex]\frac{33(196)}{2}[/tex]

Renee bought 7 potatoes at the supermarket. The shortest diameter of each, in centimeters, is shown below
Answer:
2, 3, 4
Step-by-step explanation:
Renee bought 7 potatoes at the supermarket. The shortest diameter of each,
in centimeters, is shown below.
2, 3, 4, 4, 6, 6, 7
After Renee used one potato to make dinner, the median diameter of the remaining potatoes was 5 centimeters. Which of these could be the diameter, in centimeters, of the potato Reneetsed?
Solution:
The median of a group of numbers is the middle number when the group of numbers are arranged in a sorted manner, either ascending or descending.
The median of an even group of numbers, is gotten by taken the average of the two innermost numbers.
Given that the diameter of the potato as:
2, 3, 4, 4, 6, 6, 7
Given that after removing one potato, the median of the remaining potatoes was 5 centimeters.
After removing one potato, the remaining would just be 6. 6 is an even number, hence the median would be the average of the 2 middle numbers.
To get 5 cm, it has to be the average between 4 and 6. This is only possible when a potato of diameter 2,3 or 4 is removed.
If potato with diameter 2 is removed, the remaining is 3, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 3 is removed, the remaining is 2, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 4 is removed, the remaining is 2, 3, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
