What is equation?An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x Plus 3" equals the number "9." The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. The variable x is raised to the second power in the equation "x2 + 2x - 3 = 0." Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.

For Sequence A, describe (in words) a way to produce each new term from the previous term. Write a definition for the nth term of Sequence B. If these sequences continue, which will be greater, A(9) or B(9)? Explain or show how you know.
Answer:
Sequence A is defined by subtracting 6 from the previous term and taking the absolute value, while Sequence B is the sum of the first n odd integers. B(9) > A(9).
For Sequence A, The first term is 19.To produce each new term from the previous term, subtract 6 from the previous term, then take the absolute value of the result. That is, if the previous term is x, then the next term is |x - 6|.
The nth term of Sequence B is defined as the sum of the first n positive odd integers. That is, B(n) = 1 + 3 + 5 + ... + (2n - 1) = n².To find A(9) and B(9), we can apply the rules we have for each sequence:
A(0) = 19
A(1) = |19 - 6| = 13
A(2) = |13 - 6| = 7
A(3) = |7 - 6| = 1
A(4) = |1 - 6| = 5
A(5) = |5 - 6| = 1
A(6) = |1 - 6| = 5
A(7) = |5 - 6| = 1
A(8) = |1 - 6| = 5
A(9) = |5 - 6| = 1
B(0) = 0 (the sum of the first 0 odd integers)
B(1) = 1
B(2) = 1 + 3 = 4
B(3) = 1 + 3 + 5 = 9
B(4) = 1 + 3 + 5 + 7 = 16
B(5) = 1 + 3 + 5 + 7 + 9 = 25
B(6) = 1 + 3 + 5 + 7 + 9 + 11 = 36
B(7) = 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49
B(8) = 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64
B(9) = 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 = 81
Therefore, we have A(9) = 1 and B(9) = 81. Since 81 is greater than 1, we know that B(9) is greater than A(9).Havermill Co. establishes a $400 petty cash fund on September 1.

The exact value of the trigonometric expression, given the conditions of sin and sec is -85/36.
The exact value of the trigonometric expression with u and v in Quadrant III is 304/425.
How to find the exact value ?We are given sin(u) = -3/5 with 3π/2 < u < 2π and cos(v) = 15/17 with 0 < v < π/2.
cos(v - u) = cos(v)cos(u) + sin(v)sin(u)
We are given cos(v) = 15/17 and sin(u) = -3/5. To find sin(v) and cos(u), we can use the Pythagorean identities:
sin^2(v) + cos^2(v) = 1
sin(v) = sqrt(1 - (15/17)^2) = 8/17
Similarly, for cos(u):
sin^2(u) + cos^2(u) = 1
cos(u) = -sqrt(1 - (-3/5)^2) = -4/5
Now we can find cos(v - u):
cos(v - u) = cos(v)cos(u) + sin(v)sin(u)
cos(v - u) = -36/85
Since sec(v - u) = 1/cos(v - u), we have:
sec(v - u) = 1/(-36/85) = -85/36
Since both u and v are in Quadrant III, sin(u) and cos(u) are both negative, and sin(v) and cos(v) are both negative. We are given sin(u) = -7/25 and cos(v) = -15/17.
To find sin(v) and cos(u), we can use the Pythagorean identities:
sin^2(u) + cos^2(u) = 1
cos(u) = -sqrt(1 - (-7/25)^2) = -24/25 (since u is in Quadrant III)
Similarly, for sin(v):
sin^2(v) + cos^2(v) = 1
sin(v) = -sqrt(1 - (-15/17)^2) = -8/17 (since v is in Quadrant III)
Now we can find cos(u + v):
cos(u + v) = (-24/25)(-15/17) - (-7/25)(-8/17)
cos(u + v) = 304/425

Consider the following polynomial.
q(x)=6x3+31x2+23x−20
Step 1 of 2 : Use the Rational Zero Theorem to list all of the potential rational zeros.
The potential rational zeros of the given polynomial are ±1, ±2, ±3, ±4, ±5, ±6, ±10, ±15, ±20, ±30, ±60, ±1/2, ±1/3, ±2/3, ±5/2, ±4/3, ±5/3, ±10/3, ±1/6, ±5/6, ±1/10, ±2/5, ±4/15, ±1/15, ±2/15.
How to calculate potential rational zeroes?
The Rational Zero Theorem states that if a polynomial with integer coefficients has any rational zeros, then they must have the form of a fraction p/q, where p is a constant term factor and q is a leading coefficient factor.
For the given polynomial q(x)=6x^3+31x^2+23x−20, the constant term is -20, and the leading coefficient is 6. Therefore, the potential rational zeros can be expressed as follows:
p/q = ± {factors of the constant term (-20)}/{factors of the leading coefficient (6)}
Possible factors of -20: ±1, ±2, ±4, ±5, ±10, ±20
Possible factors of 6: ±1, ±2, ±3, ±6
Therefore, the potential rational zeros are:
±1/1, ±2/1, ±4/1, ±5/1, ±10/1, ±20/1,
±1/2, ±2/2, ±4/2, ±5/2, ±10/2, ±20/2,

±1/6, ±2/6, ±4/6, ±5/6, ±10/6, ±20/6.
Simplifying and eliminating duplicates, we get:
±1, ±2, ±4, ±5, ±10, ±20,
±1/2, ±2/2, ±4/2, ±5/2, ±10/2, ±20/2 (which simplifies to ±1, ±2, ±3, ±5, ±10, ±20),

What is the meaning of "[tex]x=a^{-1}b[/tex] is a solution since [tex]aa^{-1}b=1b=b[/tex]?
Here, a a⁻¹ b = 1b = b shows that a⁻¹ is indeed inverse of a, and x = a⁻¹b is a valid solution to the equation ax = b.
Define the solution of equation?An equation is a statement that two expressions are equal. A solution of an equation is a value (or a set of values) that makes the equation true.
In the equation ax = b, the solution x = a⁻¹b means that if we multiply a by its inverse a⁻¹, we get 1, the multiplicative identity. So, when we multiply both sides of the equation by a⁻¹, we get:
a⁻¹(ax) = a⁻¹b
Multiplying a⁻¹ and a on the left side of the equation gives:
1x = a⁻¹b
which simplifies to x = a⁻¹b. This shows that x = a⁻¹b is a solution to the equation ax = b.
The statement "a a⁻¹ b = 1b = b" means that when we multiply a by its inverse a⁻¹, we get the multiplicative identity 1, and when we multiply 1 by b, we get b. So, a a⁻¹ b = 1b = b shows that a⁻¹ is indeed the inverse of a, and x = a⁻¹b is a valid solution to the equation ax = b.

Justin is younger than Hassan. Their ages are consecutive integers. Find Justin's age if the product of their ages is 210.
Justin is 14 years old, and Hassan is 15 years old.
What are integers?
The Latin term "Integer," which implies entire or intact, is where the word "integer" first appeared. Zero, positive numbers, and negative numbers make up the particular set of numbers known as integers.
Let's assume that Justin's age is x. Then, Hassan's age is x + 1, since their ages are consecutive integers and Hassan is older than Justin.
We are given that the product of their ages is 210:
x(x + 1) = 210
Expanding the left-hand side and simplifying, we get:
x² + x - 210 = 0
This is a quadratic equation in standard form. We can solve for x by using the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
where a = 1, b = 1, and c = -210.
Plugging these values into the formula, we get:
x = (-1 ± √(1² - 4(1)(-210))) / 2(1)
x = (-1 ± √(1 + 840)) / 2
x = (-1 ± √(841)) / 2
We take the positive root because x represents Justin's age, which is a positive integer. Therefore:
x = (-1 + 29) / 2 = 14
So, Justin is 14 years old, and Hassan is 15 years old.

We need a sample size of at least 879 to be 99.5% confident that our estimate of the population mean will be within 1 of the true population mean.
To determine the required sample size, we use mathematical formula:
[tex]n = (z * σ / E) ^ 2[/tex]
Where:
n: sample size
z: z-score corresponding to desired level of confidence (99.5%)
σ: population standard deviation
E: margin of error (1 in this case)
Substitute given values into formula:

Hence, in order to be 99.5% confident that our estimate of the population mean would be within 1 of the actual population mean, we need a sample size of at least 879.
It's vital to remember that the estimate will be more accurate the larger the sample size. Larger sample numbers might, however, also be more costly and time-consuming to gather. Hence, while choosing the sample size, researchers must carefully weigh the trade-offs between the required level of confidence, the margin of error, and the resources at their disposal.

(a) To find the probability that a taxi driver earns less than $1500 in a day, we need to standardize the value using the given mean and standard deviation, and then find the corresponding probability from the standard normal distribution table:
z = (1500 - 1062.5) / 350 = 1.20
Using the standard normal distribution table, the probability of a standard normal random variable being less than 1.20 is approximately 0.8849. Therefore, the probability that a taxi driver earns less than $1500 in a day is approximately:
P(X < 1500) = P(Z < 1.20) = 0.8849
(b) We need to find the value of k such that 93.7% of the drivers earn more than $k a day. This means that the probability of a driver earning less than or equal to $k a day is 1 - 0.937 = 0.063. We can standardize k using the given mean and standard deviation, and then find the corresponding z-score from the standard normal distribution table:
z = (k - 1062.5) / 350
Using the standard normal distribution table, we find that the z-score corresponding to a probability of 0.063 is approximately -1.51. Therefore:
-1.51 = (k - 1062.5) / 350
k = -1.51 * 350 + 1062.5 = $499.25 (rounded to the nearest cent)
(c) The mean of the total daily earning is:
μT = μ1 + μ2 = 1062.5 + 235.5 = 1298
The variance of the total daily earning is the sum of the variances of the two earnings, since they are assumed to be independent:
σT² = σ1² + σ2² = 350² + 84.5² ≈ 128681
Therefore, the standard deviation of the total daily earning is:
σT ≈ √128681 ≈ 358.5
(rounded to the nearest integer)
(d) To find L1 and L2, we need to find the z-scores corresponding to the lower and upper 2.2% tails of the standard normal distribution:
z1 = -1.81
z2 = 1.81
Then we can use the formula for standardizing a normal random variable to find the corresponding values of T:
z1 = (L1 - μT) / σT
z2 = (L2 - μT) / σT
Solving for L1 and L2, we get:
L1 = μT + z1σT ≈ 1298 + (-1.81) * 358.5 ≈ $645
L2 = μT + z2σT ≈ 1298 + 1.81 * 358.5 ≈ $1951
(rounded to the nearest integer)
Question 2:
(a) We can model the transaction time of a single customer as a normal random variable with mean 20 and standard deviation 5. Then the total transaction time for 6 customers can be modeled as a normal random variable with mean 6 * 20 = 120 and standard deviation √(6 * 5²) = 15. To find the probability that 5 customers can finish the transaction within 20 seconds, we need to standardize the value using this mean and standard deviation, and then find the corresponding probability from the standard normal distribution table:
z = (5 * 20 - 120) / 15 = -0.53
Last year, an investor purchased 120 shares of stock A at $90 per share and 35 shares of stock B at $145 per share. What is the difference in overall loss or gain between selling at the current day's high price or low price?
Therefore, the overall difference in loss or gain between selling at the current day's high price or low price would be $3460.
What is expression?An expression is a mathematical or logical statement that represents a value or a result. It can consist of numbers, variables, operators, and/or functions that are combined in a specific way to form a valid statement. Expressions can be simple, such as a single number or variable, or complex, involving multiple operations and functions. In mathematics, expressions can be used to represent mathematical operations such as addition, subtraction, multiplication, division, exponentiation, and more.
Here,
To calculate the difference in overall loss or gain between selling at the current day's high price or low price for the stocks purchased, we need to know the current day's high and low prices for stock A and stock B. Once we have that information, we can use the following formula:
Difference = (Current day's high price - Purchase price) * Number of shares
Let's assume the current day's high price for stock A is $100 per share and the low price is $80 per share, while the high price for stock B is $150 per share and the low price is $130 per share.
For stock A:
Purchase price = $90 per share
Number of shares = 120 shares
Difference in overall loss or gain for stock A when selling at the high price:
Difference = ($100 - $90) * 120
= $1200
Difference in overall loss or gain for stock A when selling at the low price:
Difference = ($80 - $90) * 120
= -$1080
For stock B:
Purchase price = $145 per share
Number of shares = 35 shares
Difference in overall loss or gain for stock B when selling at the high price:
Difference = ($150 - $145) * 35
= $175
Difference in overall loss or gain for stock B when selling at the low price:
Difference = ($130 - $145) * 35
= -$525
So, the overall difference in loss or gain between selling at the current day's high price or low price would be the sum of the differences for stock A and stock B:
Overall difference in loss or gain = (Difference for stock A when selling at the high price + Difference for stock B when selling at the high price) - (Difference for stock A when selling at the low price + Difference for stock B when selling at the low price)
Overall difference in loss or gain = ($1200 + $175) - (-$1080 + -$525)
= $1855 + $1605
= $3460

each tank has a diameter of 6 ft and a height of 2 ft the cost is $5 per cubic use 3.14
It would cost $282.60 to fill a cylindrical tank with a diameter of 6 feet and a height of 2 feet.
What is cylinder?A cylinder is a three-dimensional geometric shape that consists of two parallel circular bases of equal size and shape, connected by a curved side.
According to given information:To calculate the cost of filling a tank with a diameter of 6 feet and a height of 2 feet, assuming a cost of $5 per cubic foot and using the value of pi as 3.14, we first need to calculate the volume of the tank.
The volume of a cylinder (which is the shape of the tank) is given by the formula:
V = π[tex]r^2h[/tex]
where V is the volume, r is the radius (half the diameter), and h is the height.
Since the diameter of the tank is 6 feet, the radius is 3 feet. Therefore:
V = 3.14 x [tex]3^2[/tex] x 2
= 56.52 cubic feet
Multiplying the volume of the tank by the cost per cubic foot gives us the total cost of filling the tank:
Total cost = 56.52 x $5
= $282.60
Therefore, it would cost $282.60 to fill a tank with a diameter of 6 feet and a height of 2 feet, assuming a cost of $5 per cubic foot and using the value of pi as 3.14.
