What is leaf plot?
A stem and leaf plot, also known as a stem and leaf diagram, is a way to arrange data so that it is simple to see how frequently various sorts of values occur. It is a graph that displays ordered numerical data. A stem and a leaf are divided into each piece of data.
In this instance, the number on the left of the division stands in for the number in the tens place. The value or values on the right side are the ones that fall between the tens and ones places. The number "9.1" is the equivalent of the word "911," for instance. When a number appears more than once on the right side of a division, that number appears more than once in the tens place. In this case, the three numbers 9.1, 9.4, and 9.7 are represented by the string "9 | 147".
Hence, There is an ordered array when reading the stem and leaf plot from top to bottom:
9.1 9.4 9.7 10.0 10.2 10.2 10.3 10.8 11.1 11.2 11.5 11.5 11.6 11.6 11.7 11.7 12.2 12.2 12.3 12.4 12.8 12.9 13.0 13.2

A photographer takes 12 different photographs. There are 3 sunsets, 4 oceans, and 5 mountains.
How many possible arrangements are there if all the photographs of the mountains are next to each other?
Answers
Answer:

the graph of h(x)=-x^2+4x+4
Answers
Answer:
Step-by-step explanation:
the coefficients of this quadratic are -1, 4 and 4, and so the discriminant b^2 - 4ac works out to 16 - 4(-1)(4), or 0. Thus this graph has two real, equal roots which are the same point on the graph, the vertex, the maximum of the function.
Letting x = 0, we find that y is 4. Thus, the y-intercept is (0, 4). Plot this.
Using the formula x = -b / [2a], we find the axis of symmetry:
x = -4 / [2*(-1)] = -4 / [-2] = +2
The axis of symmetry is the vertical line x = 2.
At x = 2, y = -(2)^2 + 4(2) + 4, OR -4 + 8 + 4, or 0.
The vertex and maximum value are (2, 0). The graph touches the x-axis in only one place.
Draw the axis of symmetry x = 2. Plot the vertex (2, 0) and the y-intercept. Reflect the y-intercept about the axis of symmetry to obtain a second point on the graph at the same y-value as (0, 4).

QUICK PLEASE IM COuNTING ON YOU!!!!!!! If you were to connect three light bulbs in parallel and then connect three light bulbs in series, from which circuit will the light bulbs be brighter?
Answers
Answer:
SeeStep by Step explanation
Step-by-step explanation:
Currently, light bulbs need nominal voltage in their operation ( that is if your system is 120 V phase-neutral ) they will have a nominal voltage 120 (v). For that reason, all of them need this voltage for their proper operation, which follows that in any circuit the bulbs must be installed in parallel.
If you install them in series, the first will get most of the 120 (v) let´s say 90 (V), and maybe work, but the next one won´t work because the voltage will drop and between the terminals of the second bulbs you surely measure 20 (V) or less, the third one will be working with 10 (V) according to kirchhoff´s second law
How do you find the nature of the roots of a given quadratic equation?
Answers
To find the nature of the roots of a given quadratic equation, use the quadratic formula, which is [tex]x= \frac{(-b±\sqrt{b^2-4ac} )}{2a}[/tex].
Finding the Nature of Roots of a Quadratic EquationSubstitute the values of a, b, and c from the given equation into the formula and solve for x. The nature of the roots can then be determined by examining the sign of the discriminant, b² - 4ac.
If the discriminant is positive, the quadratic equation will have two real roots; if the discriminant is zero, the quadratic equation will have one real root; and if the discriminant is negative, the quadratic equation will have two complex roots.

The scale factor of the blueprint of a gymnasium to the actual gymnasium is 1 in15 ft . The area of the floor on the blueprint is 114 in2 . What is the area of the actual gymnasium
Answers
The area of the actual gymnasium is 25,650 square feet.
We know that the scale factor of the blueprint to the actual gymnasium is 1 in 15 ft, which means that every 1 inch on the blueprint represents 15 feet in the actual gymnasium. To find the area of the actual gymnasium, we can use the formula:
Area of actual = (Area of blueprint) x (Scale factor)²
We know that the area of the floor on the blueprint is 114 square inches, so we can plug that into the formula:
Area of actual = 114 in² x (15 ft/1 in)² = 114 in² x 225 ft² = 25,650 ft²
Therefore, the area of the actual gymnasium is 25,650 square feet.

The variable is going to be the amount of money Jason has before his grandmother gives him money.

False, because a logarithmic function is defunded only for positive real numbers
False, because a logarithmic function is defined only for non-negative real numbers
False, because a logarithmic function is defined only for negative real numbers
Answers
Answer: Choice A
False, because a logarithmic function is defined only for positive real numbers.
===========================================================
Explanation:
Using your calculator, you should see that ln(0) is undefined or it leads to some kind of error. The same happens when you try ln(-1) or any other negative number. So ln(x) only allows x > 0. This applies to any log function, and not just the natural log function.
This is why choice A is the answer. Choice B is close, but the use of "non-negative" is not correct because that means 0 is involved. But as explained above, 0 is not allowed as part of the domain.
-----------------
Extra info (optional section)
As for why 0 and negative numbers are not allowed, you have to look carefully at what logs are designed for. They were formed to help solve exponential equations. Consider the following equation
2^x = 16
We could do guess and check to see which value would replace x. You should find that x = 4 is the solution. Though another way to solve is to use logs. The given equation converts to the log form of [tex]x = \log_2(16)[/tex]; note how the number inside the parenthesis is positive. We can't have 2^x equal to a negative value, due to powers of a positive number being a positive result. So that's why we rule out negative numbers as part of the domain. Zero is excluded for similar reasoning.

The difference between log with base 10 and log with base e is that the log with base 10 is called a common logarithmic function and the log with base e is called a Natural Logarithmic Function .
What is Logarithmic Function ?
The logarithm is defined as a power to which a number must be raised in order to get some other values. Log is the most convenient way to express the large numbers.
The Logarithm with base 10 is defined as a power to which the number must be raised to get some other number. It can also be called as the logarithm of base 10, or common logarithm.
The general form of Common logarithm is written as: [tex]log_{10} (x)[/tex] ;
The Logarithm with base e is called as Natural Log , where e is an irrational number .

Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.

When you're looking for f(3), you want the y-value that corresponds to the x-value of 3. Find it by locating 3 on the x-axis. Then follow the vertical grid line to the point where the function value is shown. From there, identify the y-coordinate of that point. That y-coordinate is f(3).
f(3) = -2

The open dots at the ends of the curves at x=3 mean the function is not defined at those points: (3, 1) or (3, -9). The solid dot at (3, -2) tells you the function value at x=3 is -2.
