What term should be inserted in m² +........+ 1/m² it a perfect square?
Answer: The given expression is:
m² +........+ 1/m²
We can notice that the expression has an even number of terms, and the first and last term are perfect squares, which suggests that it might be possible to write the expression as the square of a binomial.
Let's try to write the expression in the form of (a + b)²:
(a + b)² = a² + 2ab + b²
If we set a = m and b = 1/m, we get:
(a + b)² = m² + 2(m)(1/m) + (1/m)² = m² + 2 + 1/m²
Comparing this with the given expression, we see that it is the same as the given expression with 2 added to it.
Therefore, to make the given expression a perfect square, we need to add 2 to it.
So, the term to be inserted is 2.
The expression m² +........+ 1/m² can be written as (m + 1/m)² - 2.

What is truth table in discrete mathematics?
In discrete mathematics, a truth table is a table that lists all possible combinations of truth values for a given set of logical variables and shows the resulting truth values of a compound proposition.
In discrete mathematics, a truth table is a table that lists all possible combinations of truth values (usually either true or false) for a given set of logical variables and shows the resulting truth values of a compound proposition (a logical expression formed by combining the variables using logical operators such as AND, OR, and NOT). Each row of the truth table represents one possible combination of truth values, and the columns represent the variables and the various intermediate steps of the logical calculation. Truth tables are often used to determine the truth values of complex propositions and to test the validity of logical arguments.

A boat traveled 165 miles each way downstream and back. The trip downstream took 11 hours.
The trip back took 15 hours. What is the speed of the boat in still water? What is the speed of
the current?
The speed of the boat in still water is 20.625 km/hr. and the speed of the current is 66 km/hr.
What is the relation of speed and distance?The speed formula is speed = distance / time.
Consider x= speed of current and y = speed of still water
The speed of the boat in still water can be calculated by dividing the total distance traveled by the total time taken;
(165 km x 2 = 330 km)
(5 hours + 11 hours = 16 hours).
Therefore, the speed of the boat in still water
330 km/16 hours = 20.625 km/hr.
The speed of the current can be calculated by dividing the total distance traveled by the total time taken for the downstream trip ;
(165 km x 2 = 330 km)
(5 hours).
Therefore, the speed of the current = 330 km/5 hours = 66 km/hr.
Hence,
speed of still water = 20.625 km/hr.
speed of current = 66 km/hr

a. How much is the down payment?
b. What is the total amount of the monthly payments?
c. How much did Jean pay for the snow thrower on the installment plan?
d. What is the total finance charge?
Down payment = $198, total monthly payment = $2088, installment price = $2286, finance charge = $1782
What is down payment?Down payment is the amount of money that a purchaser needs to pay at the early stage of purchasing an expensive goods.
How to calculate down payment, total monthly payment and total finance charge?
Given, purchasing price = $1980, 18 monthly payments of $116 each.
down payment = 10%
amount of down payment = $1980 × 10/100
= $198
Total amount of monthly payment = $116 × 18 = $2088
Total paid for the snow thrower on the installment plan = Down payment + all monthly payment = $198 + $2088
Total installment price = $2286
total finance charge = Stated purchased price - down payment
= $1980 - $198

There are 2 questions.
Answer:
27) #3 --> 12x - 24 = 60
29) 2x^2 + x - 15
Step-by-step explanation:
27) If x represents the number of boxes, and there are 12 cookies in each box, multiplying 12 by x results in the total number of cookies Kendal bought. However, she kept 2 boxes for herself, which is the same as 2(12) = 24 cookies. Kendal ended up with 60 cookies at the party, so subtracting 24 cookies from the total number of cookies (12x) equals 60 cookies.
29) (3 + x)(2x - 5)
3 * 2x = 6x
3(-5) = -15
x * 2x = 2x^2
x(-5) = -5x
6x - 15 + 2x^2 - 5x =

you lease a car vauled at 23495 for 3 years
at 429.95/month
The amount of interest paid over the 3-year lease is $4,643.64 for a car.
What is a monthly payment?A monthly payment is a payment made every month to disburse loans or advances.
First, we need to calculate the total amount paid over the 3-year lease.
The monthly payment is $429.95, and there are 36 months in the lease, so:
Total lease payments = 36 x $429.95 = $15,478.20
The down payment of $500 is separate from the lease payments, so we don't include it in this calculation.
Next, we need to calculate the interest paid over the 3-year lease. We are told that interest is 30% of the monthly payment, so:
Monthly interest = 30% of $429.95 = $128.99
To find the total interest paid over the 3-year lease, we can simply multiply the monthly interest by the number of months in the lease:
Total interest paid = 36 x $128.99 = $4,643.64
Therefore, the amount of interest paid over the 3-year lease is $4,643.64.

two angles are supplementary if the sum of their measures is 180. angles A and B are supplementary. if the measure of angle A is 78 write and solve an addition equation to find the measure of angle B.
Answer:
78° + B = 180°
B = 102°
Step-by-step explanation:
"Supplementary" means angle A and B added together are 180°.
We know A is 78, but we don't know B
Write an equation:
A + B = 180°
Fill in what we know.
78° + B = 180° this is the equation the question is asking for.
To solve, subtract 78 from both sides of the equation.

Using trigonometric identities to simplify the following expression:
tan(θ)cot(θ)
Answer:
Step-by-step explanation:
The expression tan(θ)cot(θ) can be simplified using the trigonometric identity:
tan(θ) = sin(θ) / cos(θ)
cot(θ) = cos(θ) / sin(θ)
So,
tan(θ)cot(θ) = (sin(θ) / cos(θ)) x (cos(θ) / sin(θ))
= sin(θ) x cos(θ) / (cos(θ) x sin(θ))
= sin^2(θ) / sin^2(θ)
= 1
Therefore, tan(θ)cot(θ) = 1.

what is 8.75 as a fraction?
The number 8.75 is equivalent to the fraction 35/4 in its simplest form.
To convert 8.75 to a fraction, we can write it as a fraction with a denominator of 1. We then multiply both the numerator and denominator by 100 to get rid of the decimal point. This gives us:
8.75 = 8.75/1
= 875/100
Next, we want to get rid of the decimal point, which we can do by multiplying both the numerator and denominator by a power of 10 that moves the decimal point of the numerator to the right until it disappears. In this case, we can multiply both the numerator and denominator by 100, which gives us:
8.75/1 x 100/100 = 875/100
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 25. This gives us:
875/100 = (875/25) / (100/25) = 35/4
Therefore, we conclude that 8.75 is equivalent to the fraction 35/4 in its simplest form.

If a shopkeeper gives you a 15%discount on shirt of having total price 50. What price will you give after discount ?
If a shopkeeper gives you a 15% discount on shirt of having total price 50, the price you will give after the 15% discount is 42.5 dollars.
If the original price of the shirt is 50 dollars, and the shopkeeper gives a discount of 15%, then the discount amount is calculated by:
Discount = Original price x Discount rate
Discount = 50 x 0.15
Discount = 7.5 dollars
The discounted price is calculated by subtracting the discount from the original price:
Discounted price = Original price - Discount
Discounted price = 50 - 7.5
Discounted price = 42.5 dollars
The discount rate of 15% means that you will save 15% of the original price, which is 7.5 dollars in this case. The discounted price is the price after subtracting the discount amount from the original price.

Step-by-step explanation:
The given situation can be expressed as an inequality as p + n ≤ 20.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given that,
Ethan has p pennies and n nickels.
Number of pennies = p
Number of nickels = n
Total number of coins is no more than 20.
This means that the combined total of pennies and nickels does not exceed 20.
sum of p and n is less than or equal to 20.
p + n ≤ 20
Hence the required inequality expression is p + n ≤ 20.
