Each polygon is divided into a number of triangles. Find the number of triangles if the number of sides in a polygon is: (a) 6
Answer:
4 triangles
Step-by-step explanation:
the number of triangles in a polygon is (the number of sides in the polygon - 2)
The number of triangles inside a polygon with six sides are 4.
What is a polygon? What is a mathematical function, equation and expression? polygon : A polygon can be defined as a flat or plane, two-dimensional closed shape bounded with straight sides.function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that the number of sides in a polygon is 6.
If the polygon has {n} sides, then the number of triangle in a polygon is → (n – 2).For n = 6, the number of triangles would be - (6 - 2) = 4Therefore, the number of triangles inside a polygon with six sides are 4.

What is (f + g)(x)? f(x) = -5x + 3 g(x) = -3x? Write your answer as a polynomial or a rational function in simplest form.
Answer:
- 8x + 3
Step-by-step explanation:
(f + g)(x)
= f(x) + g(x)
= - 5x + 3 + (- 3x)
= - 5x + 3 - 3x ← collect like terms

A rectangular field, 360 m of length and 150 m of width, is divided in smaller square-size plots. The area of each of these plots is the biggest possible. What is the length of the side of a square plot?
Answer:
60
Step-by-step explanation:
Greatest common factor of 360 and 150 is 30
that means one side of square-size plots will be 30 m
our total area is 360x150
area of square-size plot is 30x30
360x150/30x30 = 12x5 = 60

Divide. 9x4−12x3+103x2+2
Answer:
208
Step-by-step explanation:
The division result is: Quotient: [tex]3x^2 + 9x^2 - 107x^2[/tex], Remainder: -33 Here's the polynomial division step by step: [tex]3x^2 + 1 | 9x^4 - 12x^3 + 103x^2 + 2[/tex]
Step 1: Divide the highest degree term of the dividend by the highest degree term of the divisor:
[tex]3x^2 + 1 | 9x^4 - 12x^3 + 103x^2 + 2[/tex]
[tex]9x^4 + 3x^2[/tex]
---------------
[tex]-12x^3 + 103x^2[/tex]
Step 2: Multiply the divisor by the result from step 1 (3x^2 + 1) and subtract the result from the dividend:
[tex]3x^2 + 1 | 9x^4 - 12x^3 + 103x^2 + 2\\[/tex]
[tex]9x^4 + 3x^2[/tex]
---------------
[tex]-12x^3 + 103x^2[/tex]
[tex]-12x^3 - 4x^2[/tex]
---------------
[tex]107x^2 + 2[/tex]
Step 3: Divide the highest degree term of the new dividend (107x^2) by the highest degree term of the divisor (3x^2), and perform the division:
[tex]3x^2 + 1 | 9x^4 - 12x^3 + 103x^2 + 2[/tex]
[tex]9x^4 + 3x^2[/tex]
---------------
[tex]-12x^3 + 103x^2[/tex]
[tex]-12x^3 - 4x^2[/tex]
---------------
[tex]107x^2 + 2 \\ 107x^2 + 35[/tex]
-------------
-33
Since the result (-33) has a lower degree than the divisor (3x^2 + 1), we can't proceed with further division.
So, the division result is:
Quotient: [tex]3x^2 + 9x^2 - 107x^2[/tex]
Remainder: -33

Hi ;-)
[tex](r+2)(r-3)=0\\\\r+2=0 \ \vee \ r-3=0\\\\\boxed{r=-2} \ \vee \ \boxed{r=3}[/tex]
Answer:
r = -2 , 3
Step-by-step explanation:
(r + 2)(r -3) = 0
r + 2 = 0 ; r - 3 = 0
Subtract 2 from both sides ; add 3 to both sides
r = -2 ; r = 3
r = -2 , 3

Answer: The profit percent is 20%
Step-by-step explanation:
CP = Rs 10,000
SP = Rs 12,000
so
Profit% = (12,000-10,000)/10,000 * 100%
= 2,000/10,000 * 100%
= 1/5 * 100%

What is the solution to the system of equations?
Help me get the anwser to this Equation
Answer:
The answer depends on x.value
Step-by-step explanation:
I. It's linear equation
y = mx + b
when y is output, x is input, m is slope and b is addition
So if x = -1
y = -4/3(-1) - 2
= 4/3 - 2
= (4-6)/3
y = -2/3
It will be something like this (-1, -2/3) when -1 is x.value, -2/3 is y.value
You can given x.value be anything like 0, 1, 2, 3 the graph will be like this

where

In our example the vertex

Given that this passes through the point

Find the constant of proportionality (r) in the equation y=rx
Answer:
r = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given the proportional equation
y = rx ← r is the constant of proportion
Divide both sides by x
[tex]\frac{y}{x}[/tex] = r
Use any ordered pair from the table.
Using (8, 2 ) , then
r = [tex]\frac{2}{8}[/tex] = [tex]\frac{1}{4}[/tex]
Answer:
1/4
Step-by-step explanation:
Multiplying the input (x) by (1/4) results in the output. This is direct proportion, and the constant of proportionality is (1/4).

Answer:
Step-by-step explanation:
Those two angles are equal. They are corresponding angles. In two parallel lines crossed by a transversal. 8 angles are produced. 4 have one value and the other 4 are supplementary to the first four.
These 2 are part of the first group of 4.
So 12x - 8 = 104
12x - 8 + 8 = 104 + 8

put the following equation of a line into slope intercept form simplifying all fractions 5x + 2y = -6
Answer:
The general equation of a slope-intercept form is as below;
[tex]y = mx + c[/tex]
m » slope / gradient
c » y - intercept
x » x - intercept
Since our equation is 5x + 2y = -6, make y the subject:
[tex]5x + 2y = - 6 [/tex]
subtract 5x from either sides:
[tex](5x + 2y) - 5x = - 6 - 5x \\ 2y = - 5x - 6[/tex]
apply the division rule of equality:
[tex] \frac{2y}{2} = \frac{ - 5x}{2} - \frac{6}{2} \\ \\ { \boxed{ \boxed{answer : \: y = - \frac{5}{2} x - 3}}}[/tex]
slope » -5/2

Currently, you have made
78, 83, and an 80 on your tests in math. What do you need to make on the next test in order to get an average of an 82?
Answer:
87
Step-by-step explanation:
Mean(or average) = 82
let 'x' be the last test marks
Sum of marks of tests/Number of tests = Mean
(78 + 83 + 80 + x)/4 = 82
241 + x = 82 × 4
241 + x = 328
x = 328 - 241
x = 87

2. What might be a problem with using interval lengths that are too small?
A major problem with interval lengths that are too small is that it masks the shape of the distribution.
The interval length used in a distribution may be described as the size of the class or the class width. The interval length is usually important when drawing histograms and other related graphs for a grouped distribution.
The most significant effect of using a class interval which is too small is that it masks the actual shape of distribution, Hence preventing it from being distinct.
For best practice, it is essential that the class interval is of moderate width, hence enabling us to have a distribution which isn't maksed nor exaggerated.
