Use an associative law to find an expression equivalent to
s + (r + 75)
As you can see below, both expressions result in the same value of 105. This demonstrates the application of the associative law in regrouping terms and maintaining the equivalence of the expression.
The associative law in mathematics states that the grouping of numbers in an addition or multiplication operation does not affect the result. In other words, you can regroup terms within parentheses without changing the value of the expression.
Using the associative law, we can regroup the terms in the expression s + (r + 75) by removing the parentheses and rearranging the terms:
s + (r + 75) = (s + r) + 75
The expression (s + r) + 75 is equivalent to s + (r + 75) because the addition operation is associative.
Let's take an example to illustrate this:
Suppose s = 10 and r = 20.
Using the original expression:
s + (r + 75) = 10 + (20 + 75) = 10 + 95 = 105
Using the expression with regrouped terms:
(s + r) + 75 = (10 + 20) + 75 = 30 + 75 = 105
As you can see, both expressions result in the same value of 105. This demonstrates the application of the associative law in regrouping terms and maintaining the equivalence of the expression.

b. The sum of two consecutive integers is 109. Determine the integers in 4 steps.
Step 1:
Step 2:
Step 3:
Step 4:
The value of the first and second integers are 54 and 55 respectively.
What are the consecutive integers?Let
First integer = x
Second integer = x + 1
Sum of the integers = 109
So,
First integer + Second integer = Sum of the integers
x + (x + 1) = 109
x + x + 1 = 109
2x + 1 = 109
Subtract 1 from both sides
2x = 109 - 1
2x = 108
divide both sides by 2
x = 108/2
x = 54
Ultimately,
First integer = x
= 54
Second integer = x + 1
= 54 + 1
= 55
Therefore, the solution in 4 steps are;
Step 1: x + (x + 1) = 109
Step 2: 2x + 1 = 109
Step 3: 2x = 108
Step 4: x = 54

Answer: B. It is a perfect square
Step-by-step explanation:
Radical Expressions
Melissa multiplied \(\sqrt{a}\) and \(\sqrt{b}\) and got a rational number.
We are also given that a and b are both natural numbers. It means their product must be not only rational but also a natural number.
We can write that product like:
\(\sqrt{a} \cdot \sqrt{b}=\sqrt{a\cdot b}\)
If the result is a natural number, then the product of a and b must be a perfect square. so the radical disappears.

Seward Elementary School plans to sell friendship bracelets. The bracelets can be purchased from three
companies.
Company C charges $27 for 15 bracelets, plus a flat rate of $18 for shipping any number of bracelets.
Let n be a number of bracelets, and let t be the total cost in dollars.
For Company C, write an equation for the total cost in dollars t in terms of the number of friendship
bracelets n.
t=
In +
Answer:
Step-by-step explanation:
For Company C, the total cost in dollars, denoted as t, can be calculated using the following equation:
t = 27n + 18
In this equation, 27n represents the cost of the bracelets (charging $27 per bracelet), and 18 represents the flat rate for shipping any number of bracelets. By summing these two components, we obtain the total cost of the friendship bracelets from Company C in terms of the number of bracelets, n.

The function g is related to one of the parent functions
g(x) = x^2 – 3
The parent function is:
f(x)= x^2
Use function notation to write g in terms of f.
We can write g in terms of f as: g(x) = f(x) - 3 = x² - 3
What is function?
In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range. In simpler terms, a function is a set of rules that takes an input value and produces a corresponding output value.
To write g in terms of f, we can use function composition, which involves plugging the function f(x) into g(x) wherever we see x.
So, we have:
g(x) = f(x) - 3
where f(x) = x².
Substituting f(x) into g(x), we get:
g(x) = (x²) - 3
Therefore, we can write g in terms of f as:
g(x) = f(x) - 3 = x² - 3.

You need to borrow $2550 to help contribute to an upcoming family reunion. You can borrow the money from two different banks.
Bank A will lend you $2550 for six months at an interest rate of 11.5%
How much money will you owe at the end of each period of time? Which bank offer will you choose and why?
Bank B will lend you $2550 for twelve months at an interest rate of 7.5%
Amount to be repaid for Bank A is $2,696.625 and Amount to be repaid for Bank B is $2,741.25. However, I will choose Bank B because it offers a lower interest rate.
How to calculate the simple interest?The formula to calculate the simple interest is;
I = PRT
Where;
P is principal
R is rate
T is time
Now, we are given that;
Bank A;
Principal amount; P = $2550
Interest rate; R = 11.5% = 0.115
Time; t = 6 months = 0.5 years
Thus;
I = (2550 * 0.115 * 0.5)
I = $146.625
Amount to be repaid = 2550 + 146.625
Amount to be repaid = $2,696.625
Bank B;
Principal amount; P = $2550
Interest rate; R = 7.5% = 0.075
Time; t = 12 months = 1 year
Thus;
I = (2550 * 0.075 * 1)
I = $191.25
Amount to be repaid = 2550 + 191.25 = $2,741.25
Thus, bank B offers a more favorable interest rate and as such would be the preferred bank.

determine whether each of the following transfer functions represents a bibo stable causal system: H(z)=z+1/z-1
The transfer function H(z) = (z + 1)/(z - 1) represents a BIBO stable causal system.
To determine if the system is BIBO stable, we need to check whether the impulse response of the system is absolutely summable.
For a causal system, the impulse response is the same as the coefficients of the transfer function.
So we need to check whether the sum of the absolute values of the coefficients is finite.
The transfer function H(z) is:
H(z) = (z + 1)/(z - 1)
The coefficients of the transfer function are 1 and 1 for the numerator, and -1 for the denominator.
So the impulse response of the system is:
h[n] = [1, 1, 0, 0, ...] * δ[n] - [-1, 0, 0, 0, ...] * δ[n]
where δ[n] is the discrete-time impulse function.
The absolute value of the coefficients of h[n] are |1| = 1, |1| = 1, and |-1| = 1.
So the sum of the absolute values of the coefficients is:
|1| + |1| + |-1| + |0| + |0| + ... = 3
Since the sum of the absolute values of the coefficients is finite, the system is BIBO stable.

Solve the problem. The surface area of a square pyramid is 116 in.2 and the total area of the pyramid’s four triangular faces is 80 in.2 What is the length of one of the sides?
The length of one of the sides of the square base is 6 inches.
Length calculation.
Let's denote the length of one of the sides of the square base by "s" and the height of the pyramid by "h". Then, the surface area of the pyramid can be expressed as:
Surface area = area of square base + sum of areas of four triangular faces
Surface area = s^2 + 4(1/2)(s)(h)
We know that the surface area is 116 in^2 and the sum of the areas of the four triangular faces is 80 in^2. So we can substitute these values into the equation:
116 = s^2 + 4(1/2)(s)(h)
80 = 4(1/2)(s)(h)
We can simplify the second equation to get:
20 = (1/2)(s)(h)
We can solve for h by substituting the value of (1/2)(s)(h) from the second equation into the first equation:
116 = s^2 + 4(20)
116 = s^2 + 80
s^2 = 36
s = 6
Therefore, the length of one of the sides of the square base is 6 inches.
