Write the equation of a line that is perpendicular to y=½x - 9 and passes through the point (3, -2).
Answer:
y = - 2x + 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{2}[/tex] x - 9 ← is in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2 , then
y = - 2x + c ← is the partial equation
to find c substitute (3, - 2 ) into the partial equation
- 2 = - 2(3) + c = - 6 + c ( add 6 to both sides )
4 = c
y = - 2x + 4 ← equation of perpendicular line

a: theta equals pi over 3 comma 4 times pi over 3
b: theta equals pi over 3 comma 5 times pi over 3
c: theta equals 2 times pi over 3 comma 4 times pi over 3
d: theta equals 2 times pi over 3 comma 5 times pi over 3
The values in the interval [0, 2π) for which the two points would intersect as required is; Choice C; theta equals 2 times pi over 3 comma 4 times pi over 3.
What values of θ make the two functions intersect?Recall from the task content; the given functions are;
f (x) = 2cos2θ and g(x) = −1 − 4cos θ − 2cos2θ
Therefore, for intersection; f (θ) and g(θ):
2 cos²θ = −1 − 4cos θ − 2cos²θ
4cos²θ + 4cosθ + 1 = 0
let cos θ = y;
4y² + 4y + 1 = 0
y = -1/2
Therefore; -1/2 = cos θ
θ = cos-¹ (-1/2)
θ = 2π/3, 4π/3.
Ultimately, the correct answer choice is; Choice C; theta equals 2 times pi over 3 comma 4 times pi over 3.

Quadrilateral KLMN has vertices at K(6, 0), L(10, -5), M(5, -9), and N(1, -4).
Is KLMN a square? Justify your answer.
Yes, all sides are congruent, and KL and LM are perpendicular.
Yes, all sides are congruent, and KL and MN are parallel.
No, KL and LM are not perpendicular.
No, KL and MN are not parallel.
We have shown that KLMN has four congruent sides and opposite sides are parallel and perpendicular, which makes KLMN a square.
What is a graph?
A diagram (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables.
To determine if KLMN is a square, we need to check if all four sides are congruent and if opposite angles are congruent.
We can find the length of each side using the distance formula:
KL = sqrt((10 - 6)^2 + (-5 - 0)^2) = sqrt(16 + 25) = sqrt(41)
LM = sqrt((5 - 10)^2 + (-9 - (-5))^2) = sqrt(25 + 16) = sqrt(41)
MN = sqrt((1 - 5)^2 + (-4 - (-9))^2) = sqrt(16 + 25) = sqrt(41)
NK = sqrt((6 - 1)^2 + (0 - (-4))^2) = sqrt(25 + 16) = sqrt(41)
So all four sides have the same length of sqrt(41), which is a necessary condition for a square.
To check if opposite angles are congruent, we can find the slope of each pair of opposite sides:
slope KL = (-5 - 0)/(10 - 6) = -5/4
slope MN = (-4 - (-9))/(1 - 5) = 5/4
slope LM = (-9 - (-5))/(5 - 10) = -4/5
slope NK = (0 - (-4))/(6 - 1) = 4/5
We can see that the slopes of KL and MN are negative reciprocals, as are the slopes of LM and NK. This means that opposite sides are parallel and perpendicular, respectively, which is another necessary condition for a square.

What is graph?
A visual representation of the variation of one variable with relation to one or more other variables, such as a collection of dots, lines, line segments, curves, or regions.
To determine if KLMN is a square, we need to check if all four sides are congruent and if opposite angles are congruent.
We can find the length of each side using the distance formula:
KL = sqrt((10 - 6)² + (-5 - 0)²) = sqrt(16 + 25) = sqrt(41)

If a first sample has a sample variance of 12 and a second sample has a sample variance of 22 , which of the following could be the value of the pooled sample variance? 1 10 16 25
The value of the pooled sample variance is 25 when the first sample has a sample variance of 12 and a second sample has a sample variance of 22.
If a first sample has a sample variance of 12 and a second sample has a sample variance of 22, then the possible values of the pooled sample variance are given by the formula below:
Formula:
pooled sample variance = [(n₁ - 1) s₁² + (n₂ - 1) s₂²] / (n₁ + n₂ - 2)
Where s₁ and s₂ are the sample standard deviations of the first and second samples,
n₁ and n₂ are the sample sizes of the first and second samples, respectively.
Thus, substituting the given values into the formula above, we have pooled sample variance:
= [(n₁ - 1) s₁² + (n₂ - 1) s₂²] / (n₁ + n₂ - 2)
= [(n₁ - 1) 12 + (n₂ - 1) 22] / (n₁ + n₂ - 2)
Checking each of the answer options:
If pooled sample variance is 1, then:
(n₁ - 1) 12 + (n₂ - 1) 22
= (n₁ + n₂ - 2)(1)
= 12n₁ + 22n₂ - 34
= (12n₁ - 12) + (22n₂ - 22)
= 12(n₁ - 1) + 22(n₂ - 1)
The expression on the right-hand side of the equation is a sum of multiples of 12 and 22, and therefore, the expression itself will be a multiple of the greatest common divisor of 12 and 22, which is 2.
Since 34 is not a multiple of 2, the equation cannot be true if the pooled sample variance is 1.
Thus, 1 is not a possible value of the pooled sample variance.
If pooled sample variance is 10, then:
(n₁ - 1) 12 + (n₂ - 1) 22
= (n₁ + n₂ - 2)(10)
= 12n₁ + 22n₂ - 34
= (12n₁ - 12) + (22n₂ - 22)
= 12(n₁ - 1) + 22(n₂ - 1)
The expression on the right-hand side of the equation is a sum of multiples of 12 and 22, and therefore, the expression itself will be a multiple of the greatest common divisor of 12 and 22, which is 2.
Since 34 is not a multiple of 2, the equation cannot be true if the pooled sample variance is 10.
Thus, 10 is not a possible value of the pooled sample variance.
If pooled sample variance is 16, then:
(n₁ - 1) 12 + (n₂ - 1) 22
= (n₁ + n₂ - 2)(16)
= 12n₁ + 22n₂ - 34
= (12n₁ - 12) + (22n₂ - 22)
= 12(n₁ - 1) + 22(n₂ - 1)
The expression on the right-hand side of the equation is a sum of multiples of 12 and 22, and therefore, the expression itself will be a multiple of the greatest common divisor of 12 and 22, which is 2.
Since 34 is not a multiple of 2, the equation cannot be true if the pooled sample variance is 16.
Thus, 16 is not a possible value of the pooled sample variance.
If pooled sample variance is 25, then:
(n₁ - 1) 12 + (n₂ - 1) 22
= (n₁ + n₂ - 2)(25)
= 12n₁ + 22n₂ - 34
= (12n₁ - 12) + (22n₂ - 22)
= 12(n₁ - 1) + 22(n₂ - 1)
The expression on the right-hand side of the equation is a sum of multiples of 12 and 22, and therefore, the expression itself will be a multiple of the greatest common divisor of 12 and 22, which is 2.
Since 46 is a multiple of 2, the equation can be true if the pooled sample variance is 25.
Thus, 25 is a possible value of the pooled sample variance.

find the derivative of y equals 5 x squared sec to the power of short dash 1 end exponent (2 x minus 3 )
The derivative of the given function [tex]y = 5x^2 sec^{(-1)(2x-3)^2}[/tex] is [tex]dy/dx=-20x\sqrt{((2x-3)^2-1)}[/tex]
It can be derived as:
We can use the chain rule and the derivative of [tex]sec^{(-1)x}[/tex] which is [tex]-1/(x*\sqrt{(x^2-1)})[/tex]
First, we apply the chain rule to the function.
Let [tex]u = (2x-3)^2[/tex], then:
[tex]y = 5x^2 sec^{(-1)u}[/tex]
[tex]dy/dx = d/dx [5x^2 sec^{(-1)u}][/tex]
[tex]dy/dx = d/dx [5x^2 sec^{(-1)[(2x-3)^2]}][/tex]
[tex]dy/dx= 5x^2 d/dx[sec^{(-1)u}][/tex] (Using the chain rule)
Now, let [tex]v = u^{(1/2)} = (2x-3)[/tex].
Then:
[tex]dy/dx = 5x^2 d/dv [sec^{(-1)v}] dv/dx[/tex] (Using the chain rule again)
We have:
[tex]d/dv [sec^{(-1)v}] = -1/(v*\sqrt{(v^2-1)}) = -1/[(2x-3)*\sqrt{((2x-3)^2-1)}][/tex]
Also, [tex]dv/dx = 2[/tex]
Substituting these back into the equation:
[tex]dy/dx = 5x^2 d/dv [sec^{(-1)v}] dv/dx[/tex]
[tex]dy/dx= 5x^2 (-1/[(2x-3)*\sqrt{((2x-3)^2-1)}] (2)[/tex]
Simplifying this expression gives:
[tex]dy/dx = -20x (2x-3)/[(2x-3)*\sqrt{((2x-3)^2-1)}][/tex]
[tex]dy/dx = -20x\sqrt{((2x-3)^2-1)}[/tex]
Therefore, the derivative of y with respect to x is:
[tex]dy/dx = -20x\sqrt{((2x-3)^2-1)}[/tex]

suppose that each day the price of a stock moves up 1/8th of a point with probability 1/3 and moves down 1/8th of point with probability 2/3. if the price fluctuations from one day to another are independent, what is the probability that after 6 days the stock has its original price?
After 6 days, the probability that the stock has its original price is 5/16.
There are two possible scenarios that can take place when the stock price fluctuates from one day to the next. Either the price goes up by 1/8th of a point with probability 1/3 or it goes down by 1/8th of a point with probability 2/3.
The price of the stock after six days can be denoted as S6. The price of the stock after the first day can be represented as S0.
Since the price fluctuates either up or down by 1/8th of a point on each day, the price after six days can be represented as follows:S6 = S0 + (up, up, up, up, up, up), (up, up, up, up, up, down), (up, up, up, up, down, up), ... , (down, down, down, down, down, down)
In order to return to the original price, the stock must go up and down by the same amount. As a result, there must be an equal number of ups and downs in the six-day period.
As a result, we must calculate the probability of obtaining an equal number of ups and downs over six days.
Let's represent an increase in the stock price as 'U' and a decrease as 'D.'
The total number of ways in which the stock can go up and down over six days is [tex]2^6 = 64[/tex].
The total number of ways in which the stock can return to its original price can be calculated as follows: [tex]N(UUUDDD) = 6! / (3! * 3!) = 20[/tex]
The probability of the stock returning to its original price after six days can be calculated as:
[tex]P = N(UUUDDD) / 64 = 20 / 64 = 5 / 16[/tex]
Therefore, the probability that after 6 days the stock has its original price is 5/16.

To solve the question asked, you can say: Therefore, the final answers expressions are: E(X) = 5.8; E(X²) = 59.8; V(X) = 21.16 and E(3X + 2) = 20.4
what is expression ?In mathematics, an expression is a set of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation that represent quantities or values. Expressions can be as simple as "3 + 4" or as complex as they can contain functions like "sin(x)" or "log(y)" . Expressions can be evaluated by substituting values for variables and performing mathematical operations in the order specified. For example, if x = 2, the expression "3x + 5" is 3(2) + 5 = 11. In mathematics, formulas are often used to describe real-world situations, create equations, and simplify complex math problems.
To calculate these values, we first need to compute the mean (expected value) and variance of X, which are given by:
E(X) = ∑[x * p(x)]
= 1 * 0.05 + 2 * 0.10 + 4 * 0.35 + 8 * 0.40 + 16 * 0.10
= 5.8
E(X²) = ∑[x² * p(x)]
= 1² * 0.05 + 2² * 0.10 + 4² * 0.35 + 8² * 0.40 + 16² * 0.10
= 59.8
V(X) = E(X²) - [E(X)]²
= 59.8 - 5.8²
= 21.16
E(3X + 2) = 3E(X) + 2
= 3(5.8) + 2
= 20.4
E(3X² + 2) = 3E(X²) + 2
= 3(59.8) + 2
= 179.4
V(3X + 2) = V(3X)
= 9V(X)
= 9(21.16)
= 190.44
E(X + 1) = E(X) + 1
= 5.8 + 1
= 6.8
V(X + 1) = V(X)
= 21.16
Therefore, the final answers are:
E(X) = 5.8
E(X²) = 59.8
V(X) = 21.16
E(3X + 2) = 20.4
E(3X² + 2) = 179.4
V(3X + 2) = 190.44
E(X + 1) = 6.8
V(X + 1) = 21.16

Reduce each expression to a polynomial
((y-b)^(2))/(y-b+1)+(y-b)/(y-b+1)
The given expression ((y-b)²/(y-b+1)+(y-b)/(y-b+1) after being reduced to a polynomial, can be represented as y-b.
In order to reduce the given equation to a polynomial, we are required to simplify and combine like terms. First, we can simplify the expression in the numerator by expanding the square:
((y-b)²/(y-b+1) = (y-b)(y-b)/(y-b+1) = (y-b)²/(y-b+1)
Now, we can combine the two terms in the equation by finding a common denominator:
(y-b)²/(y-b+1) + (y-b)/(y-b+1) = [(y-b)² + (y-b)]/(y-b+1)
Next, we can combine the terms in the numerator by factoring out (y-b):
[(y-b)² + (y-b)]/(y-b+1) = (y-b)(y-b+1)/(y-b+1)
Finally, we can cancel out the common factor of (y-b+1) in the numerator and denominator to get the polynomial:
(y-b)(y-b+1)/(y-b+1) = y-b
Therefore, the equation ((y-b)²)/(y-b+1)+(y-b)/(y-b+1) after being simplified, is equivalent to the polynomial y-b.

Don bought the furniture listed below he paid $500 and will make monthly payments of $85 for the remaining amount how long will it take to pay for the furniture
Answer:
it will take approximately 5.88 months for Don to pay off the remaining amount of $R = $85t = $85(5.88) = $499.80
Step-by-step explanation:
Don paid $500 upfront and will make monthly payments of $85 for the remaining amount. Let's assume the remaining amount he needs to pay is $R. The total cost of the furniture is the sum of the amount paid upfront and the remaining amount:
Total Cost = $500 + $R
Since he will be paying $85 per month, we can set up an equation to determine the time it will take to pay off the remaining amount:
$R = $85t
where t is the number of months it will take to pay off the remaining amount.
Substituting $R = $85t in the total cost equation, we get:
Total Cost = $500 + $85t
Since we want to find the time it will take to pay off the furniture, we need to solve for t. We can equate the total cost to the amount Don will pay at the end of the payment period, which is:
Total Cost = Amount Paid
$500 + $85t = $500 + $85t + $R
$85t = $R
$500 + $85t = $500 + $85t + $85t
$500 + $170t = $500 + $R
$170t = $R
Substituting $R = $85t, we get:
$170t = $85t
t = $500/$85
t = 5.88 (rounded to two decimal places)

The average rate of change for the interval from x = 8 to x = 9 is 13,122 (3⁸to 3⁹).
What is function?Function is a self-contained block of code that performs a specific task. It is used to separate logical code into separate parts and make the code more manageable. A function can accept inputs, known as parameters, and return an output, known as a return value. Functions can be reused throughout a program, making the code more efficient and easier to debug.
This can be calculated by subtracting the starting value (3⁸ = 6561) from the ending value (3⁹ = 19683) and then dividing the result by the interval (9 - 8 = 1). Mathematically, this is expressed as (19683 - 6561) / (9 - 8) = 13,122. This result shows that the rate of change for the exponential function between x = 8 and x = 9 is 13,122.

Step-by-step explanation:

Dakota earned $6.00 in interest in Account A and 30.00$ in interest in Account B after months. If the simple interest rate is 4% for Account A and 5% for Account B, which account has the greater principal? Explain.
the principal in Account B is 4.8 times the principal in Account A.
How to solve?
Let the principal in Account A be P and the principal in Account B be Q. Also, let n be the number of months.
From the given information, we have:
Interest earned in Account A = $6.00
Interest rate in Account A = 4%
Number of months = n
Using the formula for simple interest, we have:
Interest earned in Account A = (P × 4%× n) / 12
Substituting the given values, we get:
6.00 = (P × 4% × n) / 12
P× n = 150
Similarly, we have:
Interest earned in Account B = $30.00
Interest rate in Account B = 5%
Number of months = n
Using the formula for simple interest, we have:
Interest earned in Account B = (Q× 5% × n) / 12
Substituting the given values, we get:
30.00 = (Q× 5% ×n) / 12
Q × n = 720
To compare the principals, we can divide the equation for Account B by the equation for Account A:
(Q × n) / (P× n) = 720 / 150
Simplifying, we get:
Q / P = 4.8
Therefore, the principal in Account B is 4.8 times the principal in Account A.
Since the interest rate in Account B is higher than the interest rate in Account A, we can conclude that the principal in Account B is greater than the principal in Account A.

What is X and Y?
I WILL GIVE BRAINLY IF U DONT USE CALCULATOR
The value of X is 42.5 and Y is 90.98.
How to solve equations?
To solve an equation, you need to perform the same operation on both sides of the equation until you isolate the variable on one side and have a numerical value on the other side. The process of solving an equation generally involves the following steps:
Simplify both sides of the equation by combining like terms and following the order of operations.
Add or subtract the same value from both sides of the equation to isolate the variable term.
Multiply or divide both sides of the equation by the same non-zero value to isolate the variable term.
Check your solution by plugging it back into the original equation and verifying that it satisfies the equation.
Solving the given equations :
To solve for X, we can use inverse operations to isolate the variable. Since 10 is multiplied by X, we can use the inverse operation of division by 10 to isolate X. So, dividing both sides of the equation by 10 gives:
[tex]10x/10 = 425/10[/tex]
Simplifying the left side of the equation gives:
[tex]x = 42.5[/tex]
Therefore, X is 42.5.
To solve for Y, we can use similar steps. Since 81729 is divided by Y, we can use the inverse operation of multiplication by Y to isolate Y. So, multiplying both sides of the equation by Y gives:
[tex]81729 = 898.12 \times Y[/tex]
Simplifying the right side of the equation gives:
[tex]Y = 81729 / 898.12[/tex]
[tex]Y = 90.98[/tex]
Therefore, Y is 90.98.

It takes 120 unit cubes to completely fill a rectangular prism. The prism is 10 unit cubes high. What are the other possible dimensions of the rectangular prism?
the possible dimensions of the rectangular prism are:
1 unit by 12 units by 10 units
2 units by 6 units by 10 units
3 units by 4 units by 10 units
Let the length and width of the rectangular prism be represented by l and w, respectively. Since the height of the prism is 10 unit cubes, we know that the volume of the prism is:
V = l × w × 10
We are also given that the prism requires 120 unit cubes to fill completely, which means:
V = l × w × 10 = 120
Dividing both sides by 10, we get:
l × w = 12
Now we need to find pairs of positive integers l and w that multiply to 12. These are:
1 × 12
2 × 6
3 × 4
Therefore, the possible dimensions of the rectangular prism are:
1 unit by 12 units by 10 units
2 units by 6 units by 10 units
3 units by 4 units by 10 units
Note that these dimensions are not unique, as we can also obtain different dimensions by exchanging the length and width, or by rotating the prism.

A package is delivered 3 hours 25 minutes after it is collected, it is collected at 15:39
at what time is the package delivered
Given the data in the question we calculate that the package is delivered at 18:44.
If the package is collected at 15:39 and delivered 3 hours and 25 minutes later, we can add that amount of time to the collection time to find the delivery time.
First, we need to convert 3 hours and 25 minutes to just minutes. To do this, we multiply 3 by 60 (to convert hours to minutes) and then add 25:
3 hours and 25 minutes = (3 × 60) + 25 = 185 minutes
Now we can add 185 minutes to the collection time of 15:39:
15:39 + 185 minutes = 18:44
Therefore, the package is delivered at 18:44. The delivery time of a package is the time it takes for the package to be transported from the sender to the receiver. In this case, the package was collected at 15:39 and delivered 3 hours and 25 minutes later. To find the delivery time, we added the duration of 3 hours and 25 minutes to the collection time. It is important to keep track of delivery times to ensure timely and efficient shipping, especially for time-sensitive or perishable items. Timely delivery is crucial for businesses that rely on shipping to meet customer expectations and maintain customer satisfaction.
