n divided by 6 equals 42 please explain
The value of n when is divided by 6 and it gives 42 is 252
What is division?Division is the opposite of multiplication. If 3 groups of 4 make 12 in multiplication, 12 divided into 3 equal groups give 4 in each group in division and 12 divided by 4 gives 3 in each group. This means that 3 and 4 are factors of 12
When dividing a number by another number that is not it's factor, there will be remainder for example 12 divided by 5 . It will give 2 remainder 2. This is because 5 is not a factor of 12.
Similarly, n divided by 6 to give 42. This means that 42 and 6 are factors of n
Therefore to find n we multiply 42 and 6.
n = 42×6

I NEED HELP!!!! Use the graph of the polynomial equation y=x^4-10x² + 16 to describe its concavity. How many points of inflection does this curve have?
Points of inflection does this curve have is:
Concave Up: [tex]$\left(-\infty,-\sqrt{\frac{5}{3}}\right),\left(\sqrt{\frac{5}{3}}, \infty\right)$[/tex]
Concave Down: [tex]$\left(-\sqrt{\frac{5}{3}}, \sqrt{\frac{5}{3}}\right)$[/tex]
Points of Inflection: [tex]$(-1.2910,2.1111),(1.2910,2.1111)$[/tex]
To find the concavity of a function?
We need to take the second derivative.
y' = 4x^3 - 20x
y'' = 12x^2 - 20
Finding the points of inflection involves setting the second derivative equal to 0. Add 20 over, divide by 12, and take the square root. The positive and negative square roots of 5/3 are the potential points of inflection.
Setting up a number line can help to determine concavity. Let's plug in -2 into the second derivative. From this, we have found that from negative infinity to the negative square root of 5/3, the graph is concave up, as f''(-2) > 0. f''(0) < 0, so from the negative square root of 5/3 to the positive square root of 5/3, the graph is concave down. f''(2) is also > 0, and therefore from the positive square root of 5/3 to infinity, the graph is concave up.
Since the graph shifted direction at both potential points of inflection, they are both actually points of inflection. To find the y-values for each point of inflection, plug the x-value back into the original polynomial equation.

Ron refills the oil in his car using a funnel. The upper rim of the funnel has a diameter of 8 inches. What is the rim's radius?
4 inches is the rim's radius
What is the rim's radius?The formula for finding the radius of a circle is r=d/2, where r is the radius and d is the diameter.The diameter of the funnel rim is 8 inches, so the radius is 8/2 = 4 inches. This can also be expressed as a mathematical equation as follows: r = 8/2 or r = 4. The radius of a circle is the distance from the center of the circle to its circumference.It is a measure of the size of the circle, and is used to calculate the area of a circle using the formula A = πr², where A is the area and r is the radius.The radius of the funnel rim is 4 inches, so the area can be calculated using the equation A = π(4)² = 16π. The radius is an important part of understanding the size and shape of a circle. When refilling oil in a car, a funnel with a larger radius can help to increase the flow of the oil.The radius of the funnel should be large enough to allow the oil to flow easily but not so large that it causes a mess.

In the first week of July a record 1,120 people went to the local swimming pool in the second week 125 fewer people went to the pool than in the first week in the third week 130 more people went to the pool than in the second week in the fourth week 229 fewer people went to the pool than in the third week what is the percent decrease in the number of people who went to the pool over these four weeks
There is 20% decrease in the number of people who went to the pool over these four weeks.
What is percentage?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of anything, we mean that it is 50% of everything.
Attendance of pool in first week of July = 1120
In second week, 125 fewer people joined.
Thus, attendance in second week is = 1120-125 = 995
In third week, 130 more people joined.
Thus, attendance in third week is = 995+130 = 1125
In fourth week, 229 fewer people joined.
Thus, attendance in fourth week is = 1125-229 = 896
Difference of attendance in first and fourth week = 1120-896 = 224
Percentage decrease = (Decrease number/Initial number)×100%
= (224/1120)×100%
= 0.20×100%
= 20%
Thus, there has been a 20% decrease over the four weeks.

This means that each item can either be included in the subset (x[i] = 1) or not included in the subset (x[i] = 0).
The sum of the weights of the items in the subset should not exceed the maximum capacity constraint, m. So the bounding condition for the weight of the subset is:
∑(w[i] * x[i]) <= m (for all i such that 1 <= i <= n)
This means that the sum of the weights of the items in the subset should be less than or equal to the maximum capacity constraint.

What is exponential decay?
The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, and is the initial amount, b is the decay factor, and y is the final amount.
Here, we have
This is a compound decay problem, which goes by the formula:
F = P(1-r)ˣ
Where
F is the future amount (we want it to be 20)
P is the present amount (240 now)
r is the rate of decay per minute (17.4% = 17.4/100 = 0.174)
x is the time it takes (what we want to find)
Substitute all values in the formula and we get
20 = 240(1-0.174)ˣ
20 = 240(0.826)ˣ
0.0833 = 0.826ˣ
㏑0.0833 = ㏑0.826ˣ
㏑0.0833 = x ㏑0.826

Let f(d)=-6d+54 represents the amount of firewood purchased and each night you burn six pieces of firewood. D = number of days and F = pieces of firewood. when will there be 36 pieces of firewood left?
Answers: a. end of first day B. End of second day C. end of third day D. End of fourth day
Answer: C. End of third day
Step-by-step explanation:
The question is asking when there will be 36 pieces left, so you start with the equation:
-6d + 54 = 36
Then, solve this equation:
-6d + 54 = 36
-6d = -18 (subtract 54 from both sides)
d = 3 (divide both sides by -6)
It will take 3 days until there are 36 pieces left, which is the end of the third day.
