The rectangular coordinates of the polar coordinates are as follows:-

a) x = 0 and  y = ( -2 )

b) x = ( -√3/2 ) and y = 1

To convert these polar coordinates to rectangular coordinates, we calculate the following,

a) ( 2, 3π/2 ) :

r=2 ; θ = 3π/2

x = r * cosθ

x = 2 * cos( 3π/2 )

x = 2 * 0

Therefore, x = 0

y = r * sinθ

y = 2 * sin( 3π/2 )

y = 2 * ( -1 )

Therefore, y = ( -2 )

b) ( 1, 5π/6 ) :

r = 1 ; θ = 5π/6

x = r * cosθ

x = 1 * cos( 5π/6 )

x = 1 * ( -√3/2 )

Therefore, x = ( -√3/2 )

y = r * sinθ

y = 2 * sin( 5π/6 )

y = 2 * ( 1/2 )

Therefore, y = 1

The given equation is x2−9/18​−x−3/12​=x+3/x

(a) The restrictions on x are that x cannot equal 0, 6, or -4. This is because if x were to equal any of these values, the denominator of one of the fractions in the equation would equal 0, which is undefined.

(b) The least common denominator of the fractions in the equation is 36. This is because 36 is the smallest number that is divisible by 18, 12, and x.

(c) To solve the equation, we can multiply each term by the least common denominator to eliminate the fractions:

36x2 - 18(9) - 36x - 3(3) = 36x + 3(36)

Simplifying and rearranging the terms gives us:

36x2 - 72x - 207 = 0

Using the quadratic formula, we can find the values of x:

x = (-(-72) ± √((-72)2 - 4(36)(-207)))/(2(36))

Simplifying gives us:

x = (72 ± √12960)/72

So the solutions are x = (72 + √12960)/72 and x = (72 - √12960)/72.

However, we must check these solutions against the restrictions on x. The first solution, (72 + √12960)/72, is approximately 6.8, which does not violate any of the restrictions. The second solution, (72 - √12960)/72, is approximately -0.8, which also does not violate any of the restrictions. Therefore, the solutions to the equation are x = (72 + √12960)/72 and x = (72 - √12960)/72.

The y-intercept of the continuous function in the table is (0, –6) which can be determined by looking at the first point, (0, –6).

A continuous function is a function that is defined for all values of its independent variable, and whose graph is a continuous line without breaks or gaps. It typically means that a function's value for an input can be calculated without having to consider the values of the function for other inputs.

The y-intercept of a continuous function is the point at which the graph of the function crosses the y-axis. It is the point where the x-coordinate is zero. In other words, it is the point where the graph of the function intersects the y-axis.

In the given table, the y-intercept can be determined by looking at the first point, (0, –6). This means that the y-coordinate is –6 when the x-coordinate is 0. Therefore, the y-intercept of the continuous function in the table is (0, –6).

The y-intercept also helps us to determine the slope of the function. The slope is the rate at which the function changes as we move along the x-axis. The slope can be calculated by looking at the change in the y-coordinate for a given change in the x-coordinate.

The monthly house payment will be $375.84. The annual payment  for A farmer that purchased 265 acres of land for $4,300/acre  will be $75,436.20. The annual payment  of  Larry purchased a new combine that cost $240,500will be $64,514.88.

To calculate the monthly house payment for a home loan of $55,000 at 5.25% APR for 20 years, we can use the formula:

M = P * (r / (1 - (1 + r)^(-n)))

Where M is the monthly payment, P is the principal amount, r is the monthly interest rate, and n is the number of monthly payments.

In this case, P = $55,000, r = 5.25% / 12 = 0.004375, and n = 20 * 12 = 240.

Plugging in these values, we get:

M = $55,000 * (0.004375 / (1 - (1 + 0.004375)^(-240)))

M = $375.84

Therefore, the monthly house payment will be $375.84.

#2
To calculate the annual payment for a loan of 265 acres of land at $4,300/acre with a 25% down payment and 6.75% APR over 20 years, we can use the same formula as above, but with different values for P, r, and n.

In this case, P = 265 * $4,300 * (1 - 0.25) = $845,625, r = 6.75% / 12 = 0.005625, and n = 20 * 12 = 240.

Plugging in these values, we get:

M = $845,625 * (0.005625 / (1 - (1 + 0.005625)^(-240)))

M = $6,286.35

Since this is the monthly payment, we can multiply it by 12 to get the annual payment:

A = $6,286.35 * 12 = $75,436.20

Therefore, the annual payment will be $75,436.20.

#3
To calculate the annual payment for a loan of $240,500 for a new combine with a rebate of $4,500, a trade-in of $9,500, and a down payment of $5,000 at 8% APR over 4 years, we can use the same formula as above, but with different values for P, r, and n.

In this case, P = $240,500 - $4,500 - $9,500 - $5,000 = $221,500, r = 8% / 12 = 0.006667, and n = 4 * 12 = 48.

Plugging in these values, we get:

M = $221,500 * (0.006667 / (1 - (1 + 0.006667)^(-48)))

M = $5,376.24

Since this is the monthly payment, we can multiply it by 12 to get the annual payment:

A = $5,376.24 * 12 = $64,514.88

Therefore, the annual payment will be $64,514.88.

Answer:16.67%.

Step-by-step explanation:

The ratio of raisins to almonds is 2:10, which can be simplified to 1:5.

This means that for every 6 parts of the mix, 1 part is raisins.

To find the percentage of raisins in the mix, we need to divide the amount of raisins by the total amount of mix, and then multiply by 100 to convert to a percentage.

So if we let x be the total amount of mix (in any unit of measurement), then the amount of raisins is (1/6)x.

The percentage of raisins in the mix is:

[(1/6)x / x] x 100% = 16.67%

Therefore, the percent of the raisins in the mix is 16.67%.

The ramp rises about 10.4 inches off the ground to the nearest inch.

A ramp is an inclined plane that connects two different levels, allowing people or objects to move between them with less force than if they had to be lifted vertically.

We can use trigonometry to solve this problem. Let's call the height of the ramp "h". Then we have:

tan(3.2°) = h/15

To solve for h, we can multiply both sides by 15:

h = 15 tan(3.2°)

Using a calculator, we get:

h ≈ 0.87 feet

To convert this to inches, we can multiply by 12:

h ≈ 10.4 inches

So, the ramp rises about 10.4 inches off the ground to the nearest inch.

To find a linear function h(x) given two points, we can use the formula for the slope of a line:
m = (y2 - y1) / (x2 - x1)
Where m is the slope, (x1, y1) and (x2, y2) are the two points.

In this case, the two points are (-3, -4) and (-9, -5). Plugging in the values into the formula, we get:
m = (-5 - (-4)) / (-9 - (-3))
m = (-1) / (-6)
m = 1/6
Now that we have the slope, we can use the point-slope form of a linear equation to find the function h(x):
y - y1 = m(x - x1)
Plugging in the slope and one of the points, we get:
y - (-4) = (1/6)(x - (-3))
y + 4 = (1/6)(x + 3)
y = (1/6)x + 3/6 - 4
y = (1/6)x - 21/6

Simplifying the equation, we get:
y = (1/6)x - 7/2

Therefore, the linear function h(x) is:
h(x) = (1/6)x - 7/2

Answer:

The difference in elevation between the bottom of the canyon and the bird's nest is the sum of the depths, which is:

72 1/2 + 719 2/5

To add these two mixed numbers, we first convert them to improper fractions:

72 1/2 = 145/2

719 2/5 = (3595/5) + (2/5) = 3597/5

Now we can add them:

145/2 + 3597/5

To add fractions with different denominators, we need to find a common denominator. The smallest common multiple of 2 and 5 is 10, so we can rewrite the fractions with a denominator of 10:

145/2 × 5/5 = 725/10

3597/5 × 2/2 = 7194/10

Now we can add the fractions:

725/10 + 7194/10 = 7929/10

Finally, we can simplify the fraction and convert it back to a mixed number:

7929/10 = 792 9/10

Therefore, the difference in elevation between the bottom of the canyon and the bird's nest is 792 9/10 feet.

The angle between the vectors "[−12​] and [6−1​]α" is approximately 2.03 radians.

To find the angle between the vectors, we can use the formula:

cos(α) = ([tex]V{1}[/tex] • [tex]V{2}[/tex]) / (||[tex]V{1}[/tex]|| ||[tex]V{2}[/tex]||)

Where v1 and v2 are the two vectors, and ||[tex]V{1}[/tex]|| and ||[tex]V{2}[/tex]|| are the magnitudes of the vectors.

For the given vectors:

[tex]V{1}[/tex] = [−1 2] and [tex]V{2}[/tex] = [6 −1]

[tex]V{1}[/tex]• v2 = (−1)(6) + (2)(−1) = −6 + −2 = −8

||[tex]V{1}[/tex]|| = √((-1)^2 + 2^2) = √(5)

||[tex]V{2}[/tex]|| = √(6^2 + (-1)^2) = √(37)

cos(α) = (−8) / (√(5) √(37)) = −8 / √(185)

α = cos^-1(−8 / √(185))
