Graph with x-axis labeled as number of price increases, and the y-axis labeled as profit. The curve begins at (0, 50), increases to (2.5, 81.25), and then decreases through (6.531, 0).
What is the approximate number of price increases needed to maximize profit?

2.5
50
81
The approximate number of price increases needed to maximize profit is 2.5
How to determine the number of price?From the question, we have the following parameters that can be used in our computation:
x = number of price increases
y = Profit
Also from the question, we have
Begins at (0, 50)
Increases to (2.5, 81.25)
Decrease through (6.531, 0)
This means that
Maximum = (2.5, 81.25)
Recall that
x = number of price increases
So, we have
x = 2.5
Hence, the number of price increases is 2.5

Thank you.
a toy store manager wants to display 7 identical stuffed dogs, 4 identical stuffed cats, and 3 identical stuffed teddy bears on a shelf. how many different arrangements can be made?
120120 Different number of arrangements can be made.
7 identical stuffed dogs
4 identical stuffed cats
3 identical stuffed teddy bears
Total number of objects a toy store managers want
to display = 14.
We know formula to arrange n objects in which p are identical:
There are n!/p! ways to arrange n objects in a row, and p of those ways are exactly the same.
Similarly for this problem we can say:
Different number of arrangements possible.
Here in this question value of n =14 total number of objects.
Total number of arrangements possible for 14 objects is 14! but some objects are duplicate that may be counted more than ones so we have to divide them.
number of arrangements = 14!/ (7!*4!*3!).
by solving this we get
number of arrangements = 120120.
So we can say 120120 Different number of arrangements can be made.

a random square has a side length that is a uniform [0, 1] random variable. find the expected area of the square.
The expected area of a random square which has a side length that is uniform random variable is 1/3.
What is Continuous uniform distribution?A family of symmetric probability distributions includes the continuous uniform distribution and rectangular distribution. The distribution describes an experiment with a random result that falls within predetermined bounds.
The parameters, a and b, which represent the minimum and maximum values, define the bounds. The interval may be closed (for example, [a, b]) or open (for example, (a, b)). common abbreviation for the distribution is U (a, b), where U stands for uniform distribution.
The length of the interval is defined by the difference between the bounds; intervals with the same length on the distribution's support are equally likely.
Let, side of the square = X
we know that the area of a square = side × side
= X × X
= X^{2}
now, by using Continuous uniform distribution,
E[ X^{2} ] = [tex]\int\limits^1_0 X^{2} \, dx[/tex]
= [tex][\frac{1^{3} }{3} - \frac{0^{3} }{3} ][/tex]

If g(x) is the inverse of f(x), what is the value of f(g(2))?
It is discovered that the (1) graph represents a function whose inverse is also a function using the concept of an inverse function.
What is a graph?The set of ordered pairs is the graph of a function f in mathematics, where these pairs are Cartesian coordinates of points in two-dimensional space and so form a subset of this plane in the typical situation when x and f(x) are real integers.
To develop a graph is to make a diagram that depicts the relationship between two or more objects.
Make a sequence of bars on graph paper as an example of a graph.
Since there is only one value of x in the first graph for any value of y, the inverse is also a function, making this the right answer.
The inverse is not a function in the second graph since, for instance, y = 0 when x = -1 and when x = 1.
For instance, in the third graph, the inverse is not a function because y = -3 when x = 0 and x = 2.
For instance, in the fourth graph, y = 1 for two different values of x, proving that the inverse is not a function.

find an equation of the curve that passes through the point (0, 1) and whose slope at (x, y) is 5xy.
The equation of the curve that passes through the point (0, 1) and whose slope at (x, y) is 5xy is [tex]e^{\frac{5x^2}{2} }[/tex] .
The slope of the curve is 5xy.

Since, the curve passes through (0,1) .
Therefore, x=0 and y=1 for solving 2
ln(1) = 0/2 + C
0 = 0 + C

Linsey bought 3 bags of jolly
ranchers that weighed 18 ounces
each. Bonnie bought 2 bags of jolly
ranchers that weighed 2 pounds
each. Who bought more jolly
ranchers and why?
Bonnie bought more jolly because the weight of her 2 bags is more than that of Linsey.
What is a pound weight?The pound or pound-mass is a unit of mass used in British imperial and United States customary systems of measurement.
If each Linsey's bag of jolly weighs 18 ounces then 3 bags would weigh 18 x 3 = 54 ounces
If each Bonnie's bag of jolly weighs 2 pounds then the 2 bags would weigh 2 x 2 = 4 pounds.
converting 4 pounds to ounces at the rate of 16 ounces per pound we have 16 x 4 = 64 ounces
So Bonnie bought more jolly than Linsey as the weight of the bags of Bonnie is heavier than that of Linsey.
In conclusion Bonnie bought more than Linsey as the weight of bags of Bonnie outweighs Linsey's

What is Combination ?A combination in mathematics is a choice made from a group of separate elements where the order of the selection is irrelevant.
According to the given information
Whether you can repeat numbers or not will determine which of two possibilities
First Way
If you cannot repeat the digits
Then
You might perform 6 ! or 6x5x4x3x2x1 = 720
This is so that the initial digit, which can have up to six numbers, can never be repeated. As a result, one digit cannot be repeated, therefore
6 - 1 = 5. The third digit is the same, but since you've already used two of the six digits, you can only have 4.
The alternative
If you're able to repeat :
either [tex]6^{6}[/tex] or 6x6x6x6x6

explain how you got your answer
Answer: c = -14 over 3 (c = -14/3)
Step-by-step explanation:
1. Distribute: 5c + 4 = 2(c - 5) --> 5c + 4 = 2c - 10
2. Subtract 4 From Both Sides: 5c + 4 = 2c - 10 --> 5c + 4 - 4 = 2c - 10 - 4
3. Simplify: 5c = 2c - 14
4. Subtract 2c From both sides: 5c = 2c - 14 --> 5c - 2c = 2c - 14 - 2c
5. Simplify: 3c = 14
6. Divide Both Sides By The Same Factor: 3c divided by 3 = -14 divided by 3

In other cases, it might even be more logical to do so. An infinitive is a verb's to form, such as "to go" or "to be."
When it is said that infinitives should never be split, it means an adverb should never come before the verb in the sentence "to confidently proceed."
As we know split infinitive is one in which the word "to" and the verb in the base (infinitive) form of the verb are separated by one or more words.
Adverbs are the words that split infinitives the most frequently.

The radius of the base of a cone is decreasing at a rate of 222 centimeters per minute. The height of the cone is fixed at 999 centimeters. At a certain instant, the radius is 131313 centimeters. What is the rate of change of the volume of the cone at that instant (in cubic centimeters per minute)?.
If the radius of the base of a cone is decreasing at rate of 2 cm/minute and the height is kept constant at 9 cm, the rate of change of the volume at radius 13 cm is 489.4 cm³/minute
To calculate the rate of change, we need to take the derivative of the variables with respect to time.
The volume of a cone is given by:
V = 1/3 . πr²h
Where:
r = radius of the base
h = height
Since the height of the cone is held constant, then the derivative with respect to time is:
dV/dt = 1/3 h. 2πr dr/dt
Parameters given:
dr/dt = 2 cm/minute
h = 9 cm
r = 13 cm
Hence,
dV/dt = 1/3 x 9 x 2π x 13 x 2
dV/dt = 489.4 cm³/minute
Hence, at radius 13 cm, the rate of change of the volume is 489.4 cm³/minute
