what is a constant interval and how does it appear on a graph?
Answers
A function is said to have a constant interval if, for any input, the output is the same. The graph of a function with a constant interval is parallel to the axis of the range, i.e., a horizontal line.
A constant interval refers to a specific type of interval that remains the same or constant over its entire length. In other words, the difference between any two consecutive points or numbers in a constant interval is always the same.
Let's assume that f(x) = c is a function with a constant interval.
Then,
for any [tex]x_1\leq x_2[/tex] or [tex]x_1\geq x_2[/tex],
[tex]f(x_1) = f(x_2)[/tex].
Thus, a function whose output remains constant for every input is called a function with constant intervals.

Only false statements have counterexamples. true or false
Answers
The statement 'Only false statements have counterexamples' is false.
A counterexample is an instance that disproves a statement by providing an example where the premises are true, but the conclusion is false. Thus, only false statements have counterexamples can be considered false. A true statement cannot have a counterexample because that would contradict its truth.
For example, consider the statement 'All swans are white.' A single observation of a black swan would be a counterexample that disproves this statement, showing it is false.

A) 23
B) 46
C) 371
D) 1299
Answers
Answer:
Step-by-step explanation:
Alright, lets get started.
The area of octagon is given [tex]= 10391.9[/tex]
The formula for area of octagon with side a is = [tex]2(1+\sqrt{2} )a^2[/tex]
[tex]10391.9 = 2(1+\sqrt{2} )a^2[/tex]
hence ,
[tex]a^2 = \frac{10391.9}{2(1+\sqrt{2} )}[/tex]
[tex]a^2 = 2152.2329[/tex]
[tex]a = 46.39[/tex]
Hence the length of the side of the octagon is 46 : Answer
Now perimeter of the octagon will be = [tex]8*side length[/tex]
Hence the perimeter = [tex]8*46.39 =371.1[/tex]
hence the perimeter of the octagon is 371 : Answer

Given the expression 5a2b – 13ab + 7a3 – 4b, do the following as instructed below:
1. Write the polynomial in descending order.
2. Classify the polynomial by the number of terms.
3. State the degree of the polynomial.
Thank you !!
Answers
A. The descending order of this expression is 7a^3+5a^2b-13ab-4b.
B. This is a polynomial.
C. This is a 3rd degree polynomial.
The given expression is
[tex]5 {a}^{2} b - 13ab + 7 {a}^{3} - 4b[/tex]
To write the polynomial in descending order means we should write in decreasing powers of
[tex]a[/tex]
So in descending order we have,
[tex]7 {a}^{3} + 5 {a}^{2}b - 13ab - 4b[/tex]
ANSWER TO QUESTION 2
When a polynomial is in simplified form and it has one term, we call it a monomial.
If a simplified polynomial has two terms,it is called a binomial.
If a simplified polynomial has three terms, it is called a trinomial.
If a simplified polynomial gas four or more terms, we just call it a polynomial.
The given polynomial
[tex]5 {a}^{2} b - 13ab + 7 {a}^{3} - 4b [/tex]
has four terms and it us in simplified form, so it is classified as polynomial.
ANSWER TO QUESTION 3.
The degree of the polynomial is the highest degree the polynomial has.
We calculate the degree by adding the exponents of the two variables of each term.
For instance the first term is
[tex]7 {a}^{3} = 7 {a}^{3} {b}^{0} [/tex]
[tex]degree = 3 + 0 = 3[/tex]
Since the highest degree is 3, we say the degree of the polynomial 3.
two wheels are rolled simultaneously. The radius of the smaller wheel is r feet and the radius of the larger wheel 2r feet. If both wheels did a total of 4 rotations, how much further did the large wheel travel? PLEASE SHOW STEPS TYSM
Answers
So if we open the circumference of the circle into a straight line segment, the length of this segment is C=2πR≈2*3.14*R=6.28R
4 rotations mean 4 circumferences that is 4 segments of length 6.28R,
which makes a linear distance of 4*6.28R=25.12R
i: the radius of the smaller wheel is R=r, thus it covers a distance of 25.12r feet
ii: the radius of the smaller wheel is R=2r, thus it covers a distance of 25.12*2r=50.24r (feet)
50.24r is twice 25.12r, thus the larger wheel traveled Twice the distance of the smaller one.
Answer: the larger covered twice the distance of the smaller.
A rectangular aquarium is 2/3 filled with water and then is tilted on its side until the water level coincides with one edge of the bottom. During the process, 6 quarts of water are poured out. What is the volume of the tank in quarts?
Answers
Answer:
36 Quarts
Step-by-step explanation:
Let the volume of the Aquarium be x quarts.
Hence amount of water filled in it will be
[tex]\frac{2x}{3}[/tex] quarts
Also problem says that the tank is tilted until water level coincides with one edge of the bottom. At this position , the amount of water filled in the tank will be half of the total volume , as the slant water level will be the diagonal of the tank and a diagonal divides the tank in two halves.
Hence current volume of water in the tank will be
[tex]\frac{x}{2}[/tex]
And in this process the amount of water poured out is 6 quarts. It will the difference between the amount of water earlier in the tank and the amount of water in the tank now. Hence
[tex]\frac{2x}{3}-\frac{x}{2}=6[/tex]
[tex]\frac{4x-3x}{6}=6[/tex]
[tex]x=36[/tex]
Hence the volume of the tank is 36 quarts.
