What is Piecewise Function?A function that is defined piecemeal is one that has numerous subfunctions, each of which applies to a distinct interval in the domain. Instead of being a property of the function itself, piecewise definition is a means to express the function.
A piecewise function is a function that is constructed from bits of various functions across various time intervals.

It is impossible to prove that AABC = ADEF with the information given. In order for us to prove that these two figures are congruent, we would need to know the measures of all the angles in both figures and the lengths of all the sides.

Which is the last sentence of the proof? because f e = 1, a2 b2 = c2. because f e = c, a2 b2 = c2. because a2 b2 = c2, f e = c. because a2 b2 = c2, f e = 1.
The last sentence of the proof is Because f+e=c, [tex]a^{2} + b^{2} = c^{2}[/tex]. Hence, option b is the correct answer to this question.
We have that △ABC and △CBD are right-angled triangles.
We have to prove [tex]a^{2} + b^{2} = c^{2}[/tex].
We are given the proof too.
Because △ABC and △CBD both have a right angle, and the same angle B is in both triangles, the triangles must be similar by AA.
Likewise, △ABC and △ACD both have a right angle, and the same angle A is in both triangles, so they also must be similar by AA.
The proportions and are true because they are ratios of corresponding parts of similar triangles. The two proportions can be rewritten as
[tex]a^{2}[/tex] = cf and [tex]b^{2}[/tex] = ce.
Adding [tex]b^{2}[/tex] to both sides of the first equation, [tex]a^{2}[/tex] = cf, which results in the equation [tex]a^{2} + b^{2} = cf +b^{2}[/tex].
Because [tex]b^{2}[/tex] and ce are equal, ce can be substituted into the right side of the equation for [tex]b^{2}[/tex], resulting in the equation [tex]a^{2}+b^{2}[/tex] = cf + ce.
Applying the converse of the distributive property results in the equation [tex]a^{2}+b^{2}[/tex]= c(f + e).
Now Because f+e=c, [tex]a^{2} + b^{2} = c^{2}[/tex] .
Hence, the last sentence of this proof is Because f+e=c, [tex]a^{2} + b^{2} = c^{2}[/tex].

c. Because [tex]a^{2} + b^{2} = c^{2}[/tex], f + e = c.
d. Because [tex]a^{2} + b^{2} = c^{2}[/tex], f + e = 1.
Because △ABC and △CBD both have a right angle, and the same angle B is in both triangles, the triangles must be similar by AA. Likewise, △ABC and △ACD both have a right angle, and the same angle A is in both triangles, so they also must be similar by AA.

To get rid of the split infinitive move the term that separates the infinitive from the split position.
In the given question we have to explain, how we remove split infinitives.
As we know that,
Split infinitives are grammatical constructions in which the "to" and "infinitive" halves of what is more often referred to as the to-infinitive in modern linguistics are separated by an adverb or adverbial phrase.
When an adverb is inserted between the word "to" and the infinitive verb, a split infinitive results. Move the term that separates the infinitive from the split position to get rid of the split infinitive.

two numeric variables x and y exhibit a negative correlation if a. the value of y tends to decrease as the value of x decreases. b. the value of y tends to increase as the value of x decreases. c. the value of y tends to increase as the value of x increases. d. the values of x and y always have the same difference.
If x and y are two numerical variables, they will have a negative correlation. As the value of x declines, the value of y tends to do the same.
Statistics uses the terms correlation or dependency to describe any statistical relationship between two random variables or bivariate data, regardless of whether it is causal or not. When two variables are negatively correlated, one drops when the other grows.Therefore, if the value of x decreases, the value of y will decrease as well.A negative correlation between x and y means that when x increases, y decreases, and when x decreases, y also decreases. This is expressed by the formula y = -x.

What are basic theorems of Right angle Triangle?The Pythagoras Theorem defines the relationship between a triangle's perpendicular, hypotenuse, and base. The right-angled triangle theorem is another name for this. The Pythagoras theorem states that a triangle is said to be right-angled if the sum of the squares of the perpendicular and base is equal to the square of the hypotenuse. It can be said in the following way:
If Angle equals 90° then Hypotenuse = Perpendicular∧2+ Base∧2.
The base is the side that the right angle is connected to, the neighboring side of the right angle is connected to the hypotenuse by the perpendicular, and the side that the angle is opposite to is known as the hypotenuse. The legs of the hypotenuse are another name for the base.

Garrick's measurement was 20% off and Zan's was 12% off.How to complete the statements?The complete question is added at the end of this solution
From the question, we have the following parameters that can be used in our computation:
Garrick's plant:
Actual height = 10 mmMeasured height = 8 mmZan's plant:
Actual height= 100 mmMeasured height = 88 mmGarrick's plant is shorter than Zan's plant and the difference in heights is
Actual difference = 100 mm - 10 mm = 90 mm
Measured difference = 88 mm - 8 mm = 80 mm
The percentage errors are calculated using
Percentage errors = Difference/Actual measurement * 100%
So, we have
Garrick's actual error = (10 - 8)/10 *100% = 20%
Zan's actual error = (100 - 88)/10 * 100% = 12%
Hence, Garrick's measurement was 20% off and Zan's was 12% off.

Ruby is going to a carnival that has games and rides. Each game costs $1.25 and each ride costs $2.50. Ruby spent $15 altogether at the carnival and the number of games she played is twice the number of rides she went on. Graphically solve a system of equations in order to determine the number of games Ruby played, x, and the number of rides Ruby went on, y.
$15 = 1.25x + 2.50y
x number of games, y = number of rides
Graphing this will show a line with coordinates (x, y) on it who 'fit' in this equation to make it = 15
I graphed points where both x and y are whole numbers.
These are answers to the equation that make it = 15.
Graph the line 2x = y (2 times the number of games is the number of rides)
Where the lines intersect is where number of rides is twice taht of games, and the price is 15.
Visually, we can determine that they intersect at (2.4, 4.8)
To verify that this is correct, plug them into the first function to see if this gives you 15.
It does equal 15.
While these are not whole numbers, they do make the equations true, but in the real world we would not have numbers like this.

Why might it be important to small subgroups of populations that you use a random sample?
The subgroup can be those who differ from the majority because of physical, ethnic, religious, or other differences. Include an example of a real-life situation that involves a subgroup that supports your response.
Read and reply to another student's post. Your reply should include questions and comments that add to the discussion. For example, you might point out additional reasons that subgroups benefit from random sampling, or how other subgroups might benefit in similar ways to those discussed in the post.
