A triangle is a polygon with three edges and 3 vertices. The terminology for categorizing triangles is more than two thousand years vintage, having been defined on the first actual page of Euclid's elements.
In Euclidean geometry, any three factors, while non-collinear, decide a completely unique triangle and simultaneously, a unique plane (i.e. a -dimensional Euclidean space). In different words, there's best one plane that consists of that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is the best one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is not real. this text is ready triangles in Euclidean geometry, and in particular, the Euclidean plane, except wherein otherwise stated.

What is the slope of y =- 2x 10?.
The slope of the equation y=-2x+10 is -2.
The slope of a line is a measure of its steepness and direction. In the equation y = -2x + 10, the slope is -2.
To understand this, let's first look at the slope-intercept form of a linear equation: y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).
In this case, the equation is already in the slope-intercept form and we can see that the slope is -2. The negative sign indicates that the line is sloping downward. The bigger the absolute value of the slope, steeper the line is.
In other words, the slope of a line tells us how much y changes for each unit of change in x. In this case, the slope is -2, which means that for each unit increase in x, y decreases by 2 units.
It's also worth noting that, if the slope is positive, the line will rise from left to right, if the slope is negative, the line will fall from left to right.
Therefore, The slope of the equation y=-2x+10 is -2.

The descriptors that are applicable for factor by grouping is 4 terms and 3 terms.
What is group factorization?
Factorization by grouping requires that we first group the terms according to their common factors. Method of factorization by term grouping:
(i) A factor can be extracted from each group of the supplied expression's groupings.
(ii) Factorize each group.
(iii) Next, eliminate the factor shared by the newly created group.
To factorize 4 terms use the method -
The first step is to group the first and last two terms together.
Then create a GCF by factoring each individual binomial.
Factor out the common binomial in step three.
To factorize 3 terms use the method -
Factoring out the GCF of the full phrase is the first step (from all 3 terms). There might not always be a GCF to account for (that is, the GCF is 1).
Next, select two terms to think about jointly (we may need to split a term into two parts). Subtract the two terms' GCFs.
Consider the remaining terms along with the factored pair and determine if there is any additional factoring that can be done (if anything).
A binomial cannot be factored by factor by grouping method as it contain only two terms which doesn't require further factoring using grouping method.
Both terms are not always perfect squares, there can be times when the factors are written as roots.
Therefore, descriptors are 4 terms and 3 terms.

What is linear equation ?
A linear equation is an equation in which the highest power of the variable is 1. Linear equations can be written in the form of y = mx + b, where m is the slope of the equation, x is the variable, and b is the y-intercept, the point where the line crosses the y-axis. These equations are called linear because they describe a straight line when graphed.
It depends on the specific equations and the values of a, b, d and e in the system of equations. Multiplying both sides of an equation by a non-zero constant does not change the solution set of the equation.
However, if Jim wants to use the method of elimination, which is multiplying one equation by a constant and adding or subtracting it from the other equation, then it is important to ensure that the coefficients of one variable in the two equations are opposite in sign after the multiplication. This will enable him to eliminate one variable and find the value of the other variable.

What is the domain of CD X?.
The domain of function, (cd)(x) is all real values of x except x = 2, i.e., (−∞,2)∪(2,∞).
The domain of a function is defined as a set of values accepted by function. In this case, we have a rational function. A rational function will only be defined if the denominator is not equal to zero. We have, two functions, c(x) = 5/ x - 2 and
d(x) = x + 3. We should determine the domain of (cd) (x). The product of two is (cd) (x) = c(x) . d(x)
=> (cd)(x) = (5/(x - 2) )(x + 3) = 5(x+3)/(x -2)
Which is a rational function. So, the function will be defined if the denominator is not equal to zero, i.e., x - 2 ≠ 0 => x ≠ 2. Thus, domain set of function contains all real numbers values except 2. Therefore, the required domain of function (cd) (x) is all real values of x except 2.

Is equal to 5 times its complement determine its measure?.
The measure of an angle is 5π/12 radians
Let us assume that the complement of the angle measures x degrees.
We have been given the measure of the angle is five times its complement.
So we get the measure of the angle = 5 × x
We know that two angles are complementary when their measures add to 90 degrees (π/2 radians).
So from the definition of complementary angles we get an equation,
x + 5x = π/2
We solve above equation to find the value of x.
x + 5x = π/2
6x = π/2
x = π/12 radians
This means, the measure of complement of angle is π/12 radians.
So, the measure required angle would be,

Julian's average speed for the whole journey was 8 miles per hour.
To find Julian's average speed for the whole journey, we can use the formula:
average speed = total distance / total time
We know that Julian walked from his house to the library for 2 hours at a speed of 4 miles per hour and then returned home by bicycle at a speed of 12 miles per hour.
To find the total distance, we can add the distance he walked to the distance he rode his bicycle:
total distance = distance walked + distance rode by bicycle
To find the distance he walked, we can use the formula:
distance = speed x time
distance walked = 4 miles/hour x 2 hours = 8 miles
distance rode by bicycle = 12 miles/hour x 2 hours = 24 miles
total distance = 8 miles + 24 miles = 32 miles
We know that Julian walked for 2 hours and rode for 2 hours, so we can add those times to find the total time:
total time = time walked + time rode by bicycle = 2 hours + 2 hours = 4 hours
Now we can use the formula to find Julian's average speed for the whole journey:
average speed = total distance / total time = 32 miles / 4 hours = 8 miles/hour
Therefore, Julian's average speed for the whole journey was 8 miles per hour.

Anita' lab partner corrected her by aying the actual volume of the olid wa 0. 50 cubic centimeter. What i the percent error for Anita' meaurement?
The percent error for Anita's measurement is 8%
To calculate the percent error, you need to find the difference between the measured value and the actual value, then divide that by the actual value and multiply by 100. The formula for percent error is:
% error = (|measured value - actual value| / actual value) x 100
In this case, the measured value is 0.46 cubic centimeter and the actual value is 0.50 cubic centimeter.
% error = (|0.46 - 0.50| / 0.50) x 100
% error = (0.04 / 0.50) x 100
% error = 0.08 x 100

x = - 2
2(- 2) - y = 8
- 4 - y = 8 ( add 4 to both sides )
- y = 12 ( multiply both sides by - 1 )
y = - 12 ← value of A
x = 0
2(0) - y = 8
0 - y = 8- y = 8 ( multiply both sides by - 1 )

To write an equation of the line that passes through (-3, 5) and is perpendicular to the line y = -3x - 1, we can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.
First, we need to find the slope of the line that passes through (-3, 5). Since the line is perpendicular to y = -3x - 1, we know that the slope of the line is the negative reciprocal of -3, which is 1/3. So the slope of the line is 1/3.
Next, we can use the point-slope form of a linear equation, y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
Plugging in the point (-3, 5) and the slope 1/3, we get:
y - 5 = (1/3)(x + 3)
Simplifying we get:
y = (1/3)x + (20/3)
Hence, the equation of the line that passes through (-3, 5) and is perpendicular to the line y = -3x - 1 is y = (1/3)x + (20/3).

Figure B's cone has a volume of 678.24 cu ft.
The Volume of Cone in figure B is 678.24 cu ft.
Given:
Figure A~ Figure B
Figure A: where V = 25.12 cu ft and r = 2 feet
Figure B: r= 6 ft
Now, the formula for volume of cone
= 1/3 πr²h
As, Figure A and B are similar
So, [tex]r(B) / r(A) =h(A) / h(B)\\[/tex]
[tex]= 6/2[/tex]
=3
Now, r(B) = 3 r(A)
and, h(B) = 3 h(A)
So, the volume of figure B is
V = 1/3 π(3 r(A))² (3h (A))
[tex]V = 1/3 \times 27\times 3\times \pi r^2(A) h(A)[/tex]
V = 27 πr(A)²h(A
V = 27 V(A)
V = 27 * 25.12
V = 678.24 cu ft
Thus, the volume is 678.24 cu ft.
