Which postulate should be used to show that the
triangles are congruent?
SSS should be used to show that the triangles are congruent.
What is the congruent triangle?
Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them. Two triangles must have the same angles and, as a result, must be congruent if their sides are the same.
From the given images of the triangles, it is clear that the the legs of the triangles are equal to each other.
If two legs of two triangles are equal, then the bases are equal to each other.
Thus to prove that the triangles are congruent to each other, apply SSS postulate.

A solution to a system of linear equations in two variables is an ordered pair that.
The solution to a system of linear equations is the ordered pair (or pairs) that satisfies all equations in the system.
What ordered pair is a solution to the system of linear equations?
An equation is said to linear when it is in ax+ by = c form where a , b and c are real numbers . System of linear equation consist of a set of two or more equation with same variables. such as ,
a₁ x + b₁ y = c₁
a₂ x + b₂ y = c₂
A solution to a linear system is an ordered pair (x ,y) that solves both the equations .
To check that an ordered pair is a solution ,we have to substitute the corresponding values of our variables (x ,y) into our equations and see if they satisfy both the equations.

Given the ordered pairs A(1,4) and B(0,-4), create a sine and cosine equation
The sine and cosine functions with the ordered pairs A(1,4) and B(0,-4) are given as follows:
Sine: f(x) = 4sin(π(x + π/2)).Cosine: g(x) = -4cos(πx).What is the definition of the trigonometric functions?Both the sine and the cosine functions have similar definitions, given as follows:
f(x) = asin(b(x+c))+d.g(x) = acos(b(x+c))+d.The meaning of the coefficients of the functions are presented as follows:
a is the amplitude of the trigonometric function.b: The period of the trigonometric function is of 2π/b.c is the phase shift of the trigonometric function.d is the vertical shift of the trigonometric function.The functions vary between -4 and 4, hence the amplitude is given as follows:
a = 4.
This is the standard oscillation for a trigonometric function with amplitude 4, between -4 and 4, hence the vertical shift is of:
d = 0.
The difference between the x-coordinates of the maximum and the minimum value is half the period, hence the period is of 2 x 1 = 2, and the coefficient b is:
2π/b = 2
b = π.
The cosine function has no phase shift, it just is inverted, as it should assume a value of 4 at x = 0, hence the definition is:
g(x) = -4cos(πx).
The sine function has a phase shift, as it should assume a value of -4 at -π/2, not π/2, hence it is shifted shift π/2 units, hence the definition is:
f(x) = 4sin(π(x + π/2)).

twenty tiles are numbered through and are placed into box . twenty other tiles numbered through are placed into box . one tile is randomly drawn from each box. what is the probability that the tile from box is less than and the tile from box is either even or greater than ? express your answer as a common fraction.
The probability of first tile is less than 15, is 70% and the second tile is even or greater than 25, is 60%.
In the given question we have to find the probability of first tile is less than 15 and the second tile is even or greater than 25.
Tiles numbered 1 through 20 are placed in a box.
Tiles numbered 11 through 30 are placed in a second box.
One tile is randomly drawn from each box.
Now finding the probability of first tile is less than 15.
Since in first box tile is numbered as 1 to 20.
So the outcomes of less than 15 = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14
So favourable outcome = 14
Total number of tile = 20
So the probability = 14/20 = 70%
Now finding the probability of second tile is even or greater than 25.
Since in second box tile is numbered as 11 to 30.
So the outcomes of even or greater than 25 = 12, 14, 16, 18, 20, 22, 24, 26, 27, 28, 29, 30
So favourable outcome = 12
Total number of tile = 20
So the probability = 12/20 = 60%
Hence, the probability of first tile is less than 15, is 70% and the second tile is even or greater than 25, is 60%.

The polynomial is . (Type an expression using x as the variable. Use integers or fractions for any numbers in the expression. Simplify your answer.)

The solution for this system of equations. 12x+ 15y = 34 -6x+ 5y = 3
is (x,y) =(2/3, 8/5)
Given a system of equations,
12x + 15y = 34 ------(1)
-6x + 5y = 3 ------(2),
To solve this we use the elimination method
In the elimination method, you either add or subtract the equations to get an equation in one variable.
Equation (1) + 2 × Equation (2),
We get,
(12x+15y=34)+(-12x+10y=6)
⇒ 15y+10y=34+6
⇒ 25y=40
⇒ y=40/25
⇒ y=8/5
From equation (2),
⇒ -6x+5(y)=6
⇒ -6x+5(8/5)=6
⇒ -6x+8=6
⇒ -6x=-2
⇒ x=2/3

The number of books in Hannah's home library can be described by n(x) = 4x + 2, where x is the number of months that have passed since she began expanding her library. Describe how n(x) is related to its parent function and interpret the function in the context of the situation.
n(x) is a vertical dilation of scale factor 4 followed by a translation of 2 units upwards of the parent linear function.
How is n(x) related to the parent function?
The parent linear function is:
f(x)= x
And the function n(x) is:
n(x) = 4x + 2
If first we apply a vertical dilation of scale factor 4 to the parent linear function, we will get:
n(x) = 4*f(x)
And if now we apply a translation of 2 units upwards, then we get:
n(x) =4*f(x) + 2
Replacing f(x) by x we get:
n(x) = 4*x + 2
And we returned to n(x), so these are the transformations that define our function in terms to the parent function.
And the slope 4 means that each month 4 books are added, the y-intercept 2 means that she starts with 2 books.

A poorly-built machine has three components that can independently fail with a
probability of 1/3. The machine will fail if any component fails. What is the probability
that the machine fails?
===========================================================
Explanation:
Each component has 1/3 as the probability of failure.
1 - 1/3 = 2/3 is the probability a particular component works.
Each component is independent of one another, allowing us to multiply the probabilities: (2/3)*(2/3)*(2/3) = 8/27
8/27 is the probability that all three components work simultaneously, and it's the probability that the machine works.
1 - 8/27 = 19/27 represents the probability that at least one component fails, and hence causes the entire machine to fail also.
19/27 = 0.7037 = 70.37% approximately. It appears this machine fails pretty often.

1/16 is the ratio of a blue and unbarred parrot as offspring
Dihybrid cross:
Dihybrid cross is a cross between two individuals with two observed traits that are controlled by two distinct genes. The idea of a dihybrid cross came from Gregor Mendel when he observed pea plants that were either yellow or green and either round or wrinkled. Crossing of two heterozygous individuals will result in predictable ratios for both genotype and phenotype in the offspring. The expected phenotypic ratio of crossing heterozygous parents would be Deviations from these expected ratios may indicate that the two traits are linked or that one or both traits has a non-Mendelian mode of inheritance.
When two heterozygous parents for color (Gg) and barring (Bb) are crossed, each parent's genotype is GgBb. Each parent produces four gametes, such as GB, Gb, gB, and gb. As a result, the total number of offspring will be 16, as each parent produces four gametes. Nine will be G B_, three will be G bb, three will be ggB_, and one will be ggbb.
Therefore, 1/16 is the ratio of a blue and unbarred parrot as offspring
