The cartesian equation for the curve given by r = 9 tan(θ) sec(θ) is:
y = x(sec(x))^2, where x = θ - π/2.
The given polar equation can be simplified using the trigonometric identity for tangent and secant:
r = 9 tan(θ) sec(θ)
r = 9 sin(θ) / cos(θ) * 1 / cos(θ)
r = 9 sin(θ) / cos^2(θ)
Converting to cartesian coordinates using r^2 = x^2 + y^2 and x = r cos(θ), y = r sin(θ), we get:
(x^2 + y^2) = 81 y / x^2
Multiplying both sides by x^2, we get:
x^2 + y^2 = 81y / x^2 * x^2
x^2y^2 + x^4 - 81y = 0
Substituting x = θ - π/2, we get:
(y / (θ - π/2))^2 + (y / (θ - π/2))^4 - 81y = 0
Simplifying this expression gives us the cartesian equation for the curve:
y = x(sec(x))^2, where x = θ - π/2.

You have a balance of 17,426 on your credit card. Your minimum monthly payment is 461 . If your interest rate is 15.5%, how many years will it take to pay off your card assuming you don't add any debt? Enter your response to two decimal places (ex: 1.23)
With a credit card balance of $17,426, a minimum monthly payment of $461, and an interest rate of 15.5%, we need to calculate the number of years it will take to pay off the card without adding any additional debt.
To determine the time required to pay off the credit card, we consider the monthly payment and the interest rate. Each month, a portion of the payment goes towards reducing the balance, while the remaining balance accrues interest.
To calculate the time needed for repayment, we track the decreasing balance each month. First, we determine the interest accrued on the remaining balance by multiplying it by the monthly interest rate (15.5% divided by 12).
We continue making monthly payments until the remaining balance reaches zero. By dividing the initial balance by the monthly payment minus the portion allocated to interest, we obtain the number of months needed for repayment. Finally, we divide the result by 12 to convert it into years.
In this scenario, it will take approximately 3.81 years to pay off the credit card (17,426 / (461 - (17,426 * (15.5% / 12))) / 12).

What is the slope y =- 5x 3?
Parallel lines are two straight lines that never cross. For this to happen, the lines have to have the same slope.
In this case, the equation given is in what's called "slope-intersect" form. The general form of the slope intercept formula is y=mx + b where m is the slope of the line and b is the point on the Y-axis where the line crosses.
The equation given is y=5x+3 and since the 5 is in the place of m from the general equation, 5 is the slope. Since parallel lines have the same slope, 5 is the answer.
Slope-Intercept Form:
When we're given a linear equation we can immediately see if it's in the slope-intercept form if it follows the format y=mx+b. As long as y does not have a coefficient the slope and y-intercept are the values of m and b.

if it wants to reduce the dollars flowing out of the country, the United States can limit the number of Japanese cars being imported by imposing an Import Quota.
Import Quota:
An import quota is a type of trade restriction that places a physical limit on the amount of goods that can be imported into a country during a specific period of time. Like other trade restrictions, quotas are generally used to the benefit of commodity producers in a given economy (protectionism). The essence of import quotas is to limit the amount of foreign goods that can be brought into a country. Quotas work by allowing only those authorized through a license or government contract to bring in the amount specified in the contract. When the quantity specified in the quota is reached, no more goods can be imported during this period.
There are also quota insurance programs where liability and premiums are distributed proportionately among insurers. For example, three companies have a $1,000,000 fire insurance policy per quota, Company A receives 50% ($500,000), Company B receives 30% ($300,000), and Company C receives 20% ($200,000). If the annual bonus is $5,000, Company A will receive $2,500, Company B will receive $1,500 and Company C will receive $1,000. Company A pays 50%, company B 30% and company C 20% for each claim.

A parcel of land is created by three intersecting roads, as shown. The parcel of land is in the shape of an isosceles triangle. The lengths of the sides of a 45o - 45o - 90o triangle has relationships as shown (the lengths of the legs are congruent and the length of the hypotenuse is the length of the leg(s) times the square root of 2). If the length of the longest side is approx. 240.42 yards, what is the length of the legs and what is the AREA of the parcel of land? Round your answers to the nearest yd2.
The AREA of the parcel of land area is 14382 sq yd nearest square yard
How to calculate the AREA of the parcel of land areaWe can see that the parcel of land is an isosceles triangle with two 45-degree angles. Therefore, the triangle is a 45-45-90 triangle, and the length of each leg is equal to x (say).
We know that the longest side (hypotenuse) is approximately 240.42 yards. Using the relationship in a 45-45-90 triangle, we can write:
longest side = x√2
240.42 = x√2
x = 240.42/√2
x ≈ 169.71
Therefore, the length of each leg is approximately 169.71 yards.
To find the area of the triangle, we can use the formula for the area of a triangle:
area = 1/2 * base * height
In a 45-45-90 triangle, the base and height are equal (since the triangle is isosceles), so we can use either leg as the base and height.
Using x = 169.71 as the base and height, we get:
area = 1/2 * 169.71 * 169.71
area ≈ 14382.42
Rounding to the nearest square yard, we get: area ≈ 14382 sq yd.

Explanation:
First, we need to find the prime factorization of every number. So 14, 21, and 40 are equal to the product of the following prime number:
14 = 2 x 7
21 = 3 x 7
40 = 2 x 2 x 2 x 5
Now, we need to identify all the prime numbers and the maximum number of times that every prime appears. So, the prime numbers are:
2 = Appears maximum 3 times
3 = Appears 1 time
5 = Appears 1 time
7 = Appears maximum 1 time
So, the LCM is the multiplication of the prime numbers as:
LCM = 2 x 2 x 2 x 3 x 5 x 7
LCM = 840
Therefore, the LCM is 840

Diagram 3 shows a trapezium.
Given the area of trapezium is (4x+4) cm². Find the value of x.
Answer:
B) 4
Step-by-step explanation:
The formula for calculating the area of a trapezium:
\(area = \frac{a + b}{2} \times h\)
Where a and b are parallel sides and is the height.
a = 2x+3
b = 3-x
h = x
area = 4x+4
Substitute these values in the equation:
\(4x + 4 = (\frac{2x+3+3-x}{2} )×x\)
\(4x + 4 = ( \frac{x + 6}{2} ) \times x\)
Now multiply the numerator (x+6) with x:
\(4x + 4 = \frac{x {}^{2} + 6x }{2} \)
Multiply both sides by 2 which cancels out the fraction on the right:
\(2(4x + 4) = x {}^{2} + 6x\)
\(8x + 8 = x {}^{2} + 6x\)
Bring 8x and 8 to the right by subtracting them on both sides:
\(8x + 8 - 8x - 8 = x {}^{2} + 6x - 8x - 8\)
\(0 = x {}^{2} + 6x - 8x - 8\)
\(0 = {x}^{2} - 2x - 8\)
Now we can solve for x by factorising:
What two numbers multiply to make -8 and add to make -2? The two numbers are -4 and 2, so we can factor it as:
\(0 = (x - 4)(x + 2)\)
Solving for the first solution :
\((x - 4) = 0\)
\(x = 4\)
Solving for the second solution:
\((x + 2) = 0\)
\(x = - 2\)
x is equal to 4 and -2, however, we cannot have a negative length of -2
Hence x = 4

a certain juggler usually tosses balls vertically to a height2.2yd. to what height must they be tossed if they are to spend twice as much time in the air?
To spend twice as much time in the air, the juggler must toss the balls to a height of 4.4 yards.
The time it takes for an object to fall to the ground is given by the equation:
t = sqrt(2h/g)
where h is the height of the object and g is the acceleration due to gravity (9.8 m/s²).
If the juggler wants the balls to spend twice as much time in the air, they need to toss them to a height that is four times higher. So, the new height must be:
h = 4 * 2.2 = 4.4 yards
Therefore, the juggler must toss the balls to a height of 4.4 yards if they want them to spend twice as much time in the air.
Here are some other things to consider:
The juggler's technique may also affect how long the balls stay in the air. For example, if they throw the balls with a lot of force, they will stay in the air for longer.
The air resistance may also affect how long the balls stay in the air. For example, if the air is very humid, the balls will slow down more quickly and will not stay in the air for as long.

Find the value of k and yz if y is between x and z. x y = 3 k − 2 , y z = 7 k 4 , x z = 4 k 38
Considering that y is between x and z, we have that:
The value of k is of k = 6.The length of yz is 46 units.How to find the value of k and of yz?We consider that y is between x and z, hence the length of the segment is given by:
xz = xy + yz
The separate lengths are given as follows:
xz = 4k + 38.xy = 3k - 2.yz = 7k + 4.Hence:
4k + 38 = 3k - 2 + 7k + 4.
4k + 38 = 10k + 2
6k = 36
k = 6.
Hence the length of yz is given by:
yz = 7k + 4 = 7(6) + 4 = 42 + 4 = 46 units.

(Q2) The set of line segments _____ meet the requirements to form a triangle.8 cm4 cm3 cm
To form a triangle, the set of line segments must satisfy the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore, we need to check if the given line segments 8 cm, 4 cm, and 3 cm meet this requirement.
We can start by checking if the sum of the two smaller sides (3 cm and 4 cm) is greater than the largest side (8 cm). 3 cm + 4 cm = 7 cm, which is less than 8 cm. Therefore, these three line segments cannot form a triangle.
In general, for a set of line segments to form a triangle, the largest side must be smaller than the sum of the other two sides. In this case, the line segment of 8 cm is too long compared to the other two sides, which makes it impossible to form a triangle.
In conclusion, there are no line segments that meet the requirements to form a triangle with lengths of 8 cm, 4 cm, and 3 cm.
