My teacher keeps adamantly telling me that the answer is D, and I insist it’s B. Am I right or is she right?
My reasoning, question asks for an ALWAYS true statement. Question gives 6 defined points that if plotted will show it will need to cross the x axis twice to connect all the points while being continuous. Yet functions aren’t always straight and simple so two is the bare mininum and there may be more as in between those defined points the line may have crossed multiple times. However D and C assume its exactly 2 or more than 2, therefore they are wrong. If D and C merged together then that would be better than B. Yet B is still correct on the terms of being an “always” correct statement.
Answers
the picture below is more or less some quick mockup of what that might be, and yes, 2 solutions or zeros is the bare minimum, because we know only 5 points on this continuous line, but it could have jumped a few times before going forwards and we are not privy to those points.
well, we can say that
f(x) has more than one zero
f(x) has exactly two zeros
I think within the circumstance both are acceptable, exactly 2 zeros is also acceptable, but is not exclusively the only valid choice, if any we could say "exactly 2 zeros" is a subset of the superset "more than one zero".
kinda like saying Sandra has Felines and she also has 3 cats, well, 3 cats are an exact number, but the plural Felines contains them, so both statements are equally valid, one is more general than the other, is all

Step-by-step explanation:
Look at image.
Hope it helps
The length of the hypotenuse in the right-angle triangle of length and base is 6.5 cm.
From the Pythagoras theorem, the sum of squares of the two sides of a right-angle triangle is equal to the square of the hypotenuse.
We can calculate the third side using Pythagoras' theorem, as the base and perpendicular sides are given.
Given:
Sides, x = 6 cm and y = 2.5 cm
From Pythagoras' theorem:
x² + y² = z²
6² + 2.5² = 6.5 cm
Hence, the length of the hypotenuse in the right-angle triangle is 6.5 cm.

Let logp/n=5 and logm/n=9
Answers
Answer:
we know that
log (P/N) = log P - log N
so
log P - log N = 5----------------> equation 1
log (M/N) = log M - log N
so
log M - log N = 9 ------------------> equation 2
If you subtract equation 2 from equation 1,
you have
log M - log P = 4
That means that log (M/P) = 4 ----> 10^4 = M/P ---> M = 10000P
the answer is
the relationship between P and M is
M = 10000P

The following function height_range in python language will accept a list of integers and return the difference between the tallest and shortest height.
What is a python programming language?Python is a well-liked computer programming language used to build websites and software, automate procedures, and conduct data analysis. Since Python is a general-purpose language, it may be used to create a wide range of applications and isn't specifically designed to address any particular problems. Because of its high-level built-in data structures, dynamic typing, and dynamic binding, it is appropriate for Rapid Application Development as well as for use as a scripting or glue language to connect existing components.
Given that, the Function should accept a list of integers as arguments, and the return type should be an integer value which is the difference between the maximum and minimum element from the list function will be:

What does a midpoint of a line segment create? a) a point that is equidistant to all points on the segment b) two line segments of equal length c) a point equidistant from the two endpoints
Answers
The option b and c is correct.
To solve this problem we must be aware of the concepts of line segment. And also what is a mid point.
When we connect two dots or two points it forms a line segment or we can say that line segment is part of line which is bounded by two points.
Mid-point of any line or line segment is that point which divides the line segment into two equal parts and also a point which is equidistant from the two endpoints.
So, a midpoint of a line segment divides the line segment in two equal parts and is also equidistant from the two endpoints.
Here, the appropriate option is b and c.

D) 121 degrees
Step-by-step explanation:
A linear pair is a pair of angles that share a side and a base. In other words, they are the two angles created along one line when two lines intersect. Linear pairs are always supplementary.
In this case, since supplementary angles add up to 180 degrees, we set up an equation:
<A+<B=180
(6x-19)+(11x-22)=180
17x-41=180
17x=221
x=13
Now we plug in x=13 for angle B:
11x-22
11(13)-22
143-22
121
Therefore, the measure of angle B is 121 degrees

City C; −32 is farthest from 0 on a number line.
City D; 0.5 has the least absolute value.
Answers
Answer:
The correct answer is City D.
Step-by-step explanation:
When you say the phrase, "closer to sea level" you mean the closest to the very top of the sea, like "0" on a number line.
This means, that whether it is to the left of the right of the number line (or above or below the sea) whichever one has the lowest absolute value is the closest.
Therefore, the correct answer is City D.

Answer:
[tex]x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]
Thus, -2 comes under the interval domain of the inequality (-∞, 3].
Hence, (-2, 6) is a solution to the linear inequality.
Step-by-step explanation:
Given the linear inequality
x ≤ 3
substitute the value of x = -2
-2 ≤ 3
TRUE
It is clear that -2 is indeed less than 3. Thus, the ordered pair (-2, 6) is a solution to the linear inequality.
Also,
[tex]x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]
Thus, -2 comes under the interval domain of the inequality (-∞, 3].

Answers
According to the given statement Andrea have to mark 440 yards out of 1760 for her race course.
The yard is defined as:A yard (yd) is a length unit used in various different systems, including US customary measures, Imperial units, and historic English units. It is 3 feet, 36 inches, or 0.9144 meters.
What exactly seems to be the conversion factor?A conversion factor seems to be a number that can be used to multiply and otherwise divide one set of units by another set of units. The right conversion factor must be used when converting to something like an equivalent value. For example, to convert inches to feet, the appropriate conversion value equals 12 inches equals 1 foot.
According to the given information:Want quarter-mile course for a race.
Total yards she has is a = 1760
We know that:
1 mile = 1760 yards
quarter-mile (.25) which means = 1760/4
