The Cartesian equation 2xy = 1 has the following polar equation r²·sen2θ = 1.
To convert the Cartesian equation 2xy = 1 into polar equation form, we need to use the relationships between Cartesian coordinates and polar coordinates. The relationships are as follows:
x = r cos θy = r sin θSubstituting these relations in the Cartesian equation, we proceed to solve:
2 (r·cosθ)(r·sinθ) = 1
2r²·cosθ·sinθ = 1
r²·(2cosθ·sinθ) = 1
r²·sen2θ = 1
In conclusion, the polar equation has the following form: r²·sen2θ = 1.

Answer:
x = 30
Step-by-step explanation:
ΔABC is a right-angled triangle where:
∠C = 90°
Sum of interior angles in any triangle = 180°
Therefore:
x° + 2x° + 90°= 180°
3x° + 90° = 180°
3x° = 180° - 90°
3x° = 90°
x = [tex]\frac{90}{3}[/tex]
∴Value of x = 30
Answer:
[tex]x[/tex] is equal to [tex]30\textdegree[/tex]
Step-by-step explanation:
The sum of the interior angles in a triangle is 180 degrees. This is because a triangle is a polygon with three sides and three angles, and the sum of the angles in any polygon can be found by using the formula:
sum of interior angles = (n - 2) x 180 degrees
Note: n is the number of sides.
A triangle has 3 sides. So substituting 3 in for n gives us
(3 - 2) x 180 degrees = 180 degrees
So the sum of the interior angles in a triangle is always 180 degrees.
In this example we can say that [tex]\angle A +\angle B+ \angle C=180\textdegree[/tex]
We are given a right triangle. A right angle is equal to 90 degrees.
We can conclude that
[tex]x+2x+90=180[/tex]
Lets solve for [tex]x[/tex].
Subtract 90 from both sides.
[tex]x+2x=180-90[/tex]
[tex]x+2x=90[/tex]
Add [tex]x[/tex] and [tex]2x[/tex].
[tex]3x=90[/tex]
Divide both sides by 3.
[tex]x=\frac{90}{3}[/tex]
[tex]x=30[/tex]

What is 56 prime factors?
The prime factorization of 56 is the process of breaking 56 down into its prime factors. The prime factorization of 56 is 8 x 7, 2 x 2 x 2 x 7, or 2^3 x 7^1.
One way to calculate the prime factorization of 56 is to use a factor tree. To begin, find two numbers that multiply together to equal 56. The two factors that multiply together to equal 56 are 8 and 7. Since 8 and 7 are both prime numbers, they can be written as the prime factors of 56: 56 = 8 x 7.In mathematical terms, the prime factorization of 56 can be expressed as 56 = 2 x 2 x 2 x 7, where 2 is multiplied by itself three times and then multiplied by 7. This is because 56 can also be written as 2 x 2 x 2 x 7, which is the same as 8 x 7.The prime factorization of 56 can also be expressed as the product of the prime exponents: 56 = 2^3 x 7^1. Here, 2 is raised to the third power, and 7 is raised to the first power. This expression is equivalent to 8 x 7.In summary, the prime factorization of 56 is 8 x 7, 2 x 2 x 2 x 7, or 2^3 x 7^1.

Speedy Auto Repairs uses a job-order costing system. The company's direct materials consist of replacement parts installed in customer vehicles, and its direct labor consists of the mechanics' hourly wages. Speedy's overhead costs include various items, such as the shop manager's salary, depreciation of equipment, utilities, insurance and magazine subscriptions and refreshments for the waiting room.
The company applies all of its overhead costs to jobs based on direct labor-hours. At the beginning of the year, it made the following estimates:
Direct labor-hours required to support estimated output $12,000
Fixed overhead cost $114,000
Variable overhead cost per direct labor-hour $1.00
Required:
1. Compute the predetermined overhead rate.
2. During the year, Mr. Wilkes brought in his vehicle to replace his brakes, spark plugs, and tires. The following information was available with respect to his job:
Direct materials $626
Direct labor cost $292
Direct labor hours used 4
Compute Mr. Wilkes' total job cost.
3. If Speedy establishes its selling prices using a markup percentage of 40% of its total job cost, then how much would it have charged Mr. Wilkes?
(1) The predetermined overhead rate is $10.50 per direct labor-hour.
(2) Mr. Wilkes' total job cost is $960.
(3) Speedy Auto Repairs would have charged Mr. Wilkes $1344 for the job.
1) To compute the predetermined overhead rate, we need to add the fixed and variable overhead costs, and then divide by the estimated direct labor-hours:
$114,000 + ($1.00 * 12,000) = $126,000
Predetermined overhead rate = $126,000 / 12,000 = $10.50 per direct labor-hour
2) To find Mr. Wilkes' total job cost, we need to add up the costs of the direct materials and direct labor, and then apply the predetermined overhead rate to the direct labor hours used:
Direct materials cost: $626
Direct labor cost: $292
Total direct costs: $626 + $292 = $918
Overhead cost: $10.50 * 4 = $42
Total job cost: $918 + $42 = $960
3) To find the selling price, we need to add a markup of 40% of the total job cost:
Total job cost: $960
Markup: 40% * $960 = $384
Selling price: $960 + $384 = $1344
So, Speedy Auto Repairs would have charged Mr. Wilkes $1344 for the job.

The residual value of Sally's leased car is 75%.
So, the answer is d. 75%.
To find the residual value of Sally's leased car, we can divide the value claimed by the leasing company by the original MSRP and multiply by 100 to express the answer as a percentage.
MSRP stands for Manufacturer's Suggested Retail Price. It is the price recommended by the manufacturer of a product for its retail sale.
Residual value refers to the estimated value of an asset at the end of its lease or at a specified future date. It is used in the context of lease financing or depreciation calculations and is usually expressed as a percentage of the original value of the asset. In the context of a car lease, the residual value refers to the estimated value of the car at the end of the lease term.

Step 1: –10 + 8x < 6x – 4 Step 2: –10 < –2x – 4 Step 3: –6 < –2x Step 4: ________ What is the final step in solving the inequality –2(5 – 4x) < 6x – 4?
Answer: The final step in solving the inequality -2(5 - 4x) < 6x - 4 would be to isolate x on one side of the inequality. In the previous step (-6 < -2x), we have -2x on one side of the inequality and -6 on the other. To isolate x, we divide both sides of the inequality by -2:
-6 ÷ -2 < -2x ÷ -2
Since dividing by a negative number reverses the inequality direction, we get:
3 > x
So, the final solution to the inequality -2(5 - 4x) < 6x - 4 is x > 3. This means that all values of x that are greater than 3 satisfy the inequality.

What is a fraction?Fraction is a mathematical term, which represents the portion or sub-parts of the whole thing. Basically, It has two parts: numerator and denominator.
Numerator is a number which lies on the top side, it indicates the number of equal parts taken and denominator is on the bottom side, it indicates the equal parts of the whole number.
To find the fraction of the box that Evangeline puts in each bowl, we need to divide the total amount of nuts in the box by the number of bowls.
The amount of nuts she has is 3/5 of a box.
To find the amount of nuts in each bowl, we need to divide 3/5 by 6:
(3/5) ÷ 6
To divide by a fraction, we can multiply by its reciprocal:
= (3/5) ÷ (6/1)
= (3/5) x (1/6)

(-2 -2) and y=8/3x-5 in slope intercept form
The equation of a line perpendicular to line y = 8/3x-5 in slope-intercept form that contains point (-2, -2) is y = -3x/8 - 11/4.
What is the point-slope form?Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y are the points.In Mathematics, a condition that must be met for two lines to be perpendicular is given by:
m₁ × m₂ = -1
8/3 × m₂ = -1
m₂ = -3/8.
At data point (-2, -2), a linear equation of this line can be calculated in point-slope form as follows:
y - (-2) = -3/8(x - (-2))
y + 2 = -3/8(x + 2)
y = -3x/8 - 3/4 - 2

What is the Constant of Proportionality?If the corresponding elements of two sequences of numbers, frequently experimental data, have a constant ratio, known as the coefficient of proportionality or proportionality constant, then the two sequences of numbers are proportional or directly proportional.
When two variables are directly or indirectly proportional to one another, their relationship can be expressed using the formulas y = kx or y = k/x, where k specifies the degree of correspondence between the two variables.
The proportionality constant, k, is often used.
So, the Constant of Proportionality is as follows:
C = y/x
Now, insert values as follows:
C = y/x
C = 13.35/3.56
