If m and n are positive integers, show that: 3 (m + n)! ≥ m! + n!
We can conclude the proof of inequality : 3 (m + n)! ≥ m! + n! below.
What is factorial?In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. Mathematically, we can write -
[tex]$n! = n \times (n-1) \times \dots \times 1[/tex]
Given is the inequality -
3 (m + n)! ≥ m! + n!
We have -
3 (m + n)!
3 {(m + n)(m + n - 1)(m + n - 2) ....... (3)(2)(1)}
3 {m² + mn - m + nm + n² - n}(m + n + 2) ...... (3)(2)(1)
3 {m² + n² - m - n + 2mn}(m + n + 2) ........ (3)(2)(1)
3 {m(m - 1) + n(n - 1) + 2mn}(m + n + 2) ....... (3)(2)(1)
Now, for (m! + n!) --
(m! + n!) = m(m - 1) .... (3)(2)(1) + n(n - 1) ..... (3)(2)(1)
It can be seen that -
3 {m(m - 1) + n(n - 1) + 2mn}(m + n + 2) ....... (3)(2)(1) ≥
m(m - 1) .... (3)(2)(1) + n(n - 1) ..... (3)(2)(1)
Hence, it can be seen that -
3 (m + n)! ≥ m! + n!
Therefore, we can conclude that 3 (m + n)! ≥ m! + n!.

An exponential function has a starting value of 13 and a growth rate of 0.78%. Write an equation to model the situation.
Answer:
The equation that models the situation is [tex]A(t) = 13(1.0078)^t[/tex]
Step-by-step explanation:
Exponential equation:
An exponential equation has the following format:
[tex]A(t) = A(0)(1+r)^t[/tex]
In which A(0) is the starting value and r is the growth rate, as a decimal.
Starting value of 13 and a growth rate of 0.78%.
This means that [tex]A(0) = 13, r = 0.0078[/tex]
Write an equation to model the situation.
[tex]A(t) = A(0)(1+r)^t[/tex]
[tex]A(t) = 13(1+0.0078)^t[/tex]
[tex]A(t) = 13(1.0078)^t[/tex]
The equation that models the situation is [tex]A(t) = 13(1.0078)^t[/tex]

What is a fraction?A fraction can be described as the part of a whole variable, element or number.
The several types of fractions are;
Mixed fractionsProper fractionsImproper fractionsComplex fractionsSimple fractionsAlso, proportion can be defined as a mathematical comparison between two numbers
From the information given, we have that;
6 cups of soap = 1 /4 cup of syrup
Then 18 cups of soap = x cups of syrup
cross multiply, we get;
6x = 18(1/4)
multiply the values
6x = 18/ 4
Divide both sides by the coefficient of x , we get;
x = 18/ 4 × 1/6
x = 3/ 4 cup of syrup
Hence, the value is 3/4

36
Answer:
The answer is 36
When finding a percentage you would typically multiply the decimal. Example 20% of 100. Multiply 100 x 0.20 = 20
When trying to do the opposite you would do the inverse (opposite) operation. So the inverse (opposite) operation of mulitplication is division.
Example: 20% of what number w is 20? Divide 20/0.20 = 100
Okay now lets solve your problem!
25% of what number w is 9? Divide 9/0.25 = 36
Step-by-step explanation:
25% in decimal is 0.25
9 / 0.24 = 36

What if I only know the length of the shorter side consider the triangle equilateral triangle than determine the values of n and m without using a calculator
Answer: An equilateral triangle is a three-sided polygon with three equal sides and three equal angles of 60 degrees each. If you know the length of one of the sides of an equilateral triangle, you can use the formula for the area of an equilateral triangle to determine the values of n and m. The formula for the area of an equilateral triangle is:
Area = (sqrt(3)/4) * s^2
where s is the length of one of the sides of the triangle.
To determine the values of n and m, you can rearrange the formula to solve for s. For example, if you know that the area of the triangle is n and the value of m is the length of one of the sides of the triangle, you can rearrange the formula to solve for s:
s = sqrt(4n/sqrt(3))
Then, you can use the value of s to determine the value of m.

The first, second and fourth terms of
a proportion are 16, 24 and 54
respectively. Then the third term is:
Answer: 36
Step-by-step explanation:
This is a geometric progression. The formula for a geometric progression is given as:
= ar^n-1
where
a = first term = 16
r = common ratio = 24/16 = 1.5
n = 3
Therefore, the 3rd term will be:
= ar^n-1
= 16 × 1.5^3-1
= 16 × 1.5²
= 36
Therefore, the third term of the progression is 36.
Last Saturday an accident caused a traffic jam 13 miles long on a stretch of the
interstate.
a. How many vehicles do you think were in the traffic jam if the average car's
length measures approximately 15 feet? Explain your thinking and show all
calculations.
b. Would there be more or less vehicles if you were told there were a large
number of SUVs and trucks present in this traffic jam? Explain your thinking and
show all calculations.
There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.
What is logical reasoning?Logical or deductive reasoning involves using a given set of facts or data to deduce other facts by reasoning logically.
Given that, Last Saturday, an accident caused a traffic jam 13 miles long on a stretch of the interstate.
13 miles = 68,640 feet
One car is of 15 ft
Let there be x cars,
15x = 68,640
x = 4576
Therefore, there are 4576 cars in traffic.
If there are more SUVs and trucks, their length will be more than a car and which will make less number of vehicles involved in the traffic.
Hence, There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.

Which figures show shaded
amounts that are equivalent to 1/4
The image that shows the graph equivalent to the fraction 1/4 is option A, because only one part of the 4 available is shaded.
How to identify the correct graph?To identify the correct graph, we must first identify which fraction we must represent. In this case, the fraction is 1 / 4. To understand this fraction, we must take into account that the top number (1) refers to the number of parts that are shaded and the bottom number (4) refers to the number of total parts. into which the figure is divided.
According to the above, we can infer that it is a figure that is divided into 4 parts, and one of them is shaded. So the correct choice would be option A.
