Answer:

Sin(2x)+sin(x)+cos(2x)-1

Step-by-step explanation:

The equation in x and y for the line tangent to the curve is x - √3y - √3 = 0

A given curve can be defined by both its cartesian coordinates that is in x-y  form or in polar coordinates that is in terms of r and θ there exists a relationship between two sets of coordinates

x = r cosθ

y = r sinθ

The tangent to any curve f(x) is defined by f'(x) . In order to find tangent to a given terms of r and θ , we can calculate from the above to expressions f'(x)

f'(x) = dy/dx = dx/dθ ÷ dy/dθ

It is given in the question that

r = 2 sinθ

Replacing the value of r to the standard equation,

x = (2 sinθ )cosθ = sin2θ

At θ = π/3 , x = √3 / 2

y = (2 sinθ)sinθ = 2sin²θ

At θ = π/3 , y = 3/2

Differentiating both w.r.t θ

=> dx / dθ = 2cosθ

=> dy/dθ = 4sinθcosθ

So, dy/dx = 2cosθ / 4sinθcosθ

=> 1 / 2sinθ

Therefore , slope of tangent : m = 1/2sinθ ( θ = π/3)

=> m = 1 / 2sin(π/3)

=> m = 2 / 2√3

=> m = 1 /√3

Hence , the equation of line is

( y - 3/2 ) = 1 /√3 (x -  √3 / 2)

=> √3y - 3√3/2 = x - √3/2

=> x - √3y - √3 = 0

Answer:

The amount of weeks is your independent variable, or X variable, and the height is you dependents variable.

Step-by-step explanation:

I don't know what this question is about so I'm gonna use plants as an example. The amounts of weeks that you are growing a plant is not dependent on anything. Nothing can cause change to that variable, so it would be your X. The height that your plant has grown DOES depend on how long you've grown it, so the amount of weeks, making it your Y variable.

The triangle with sides 44, 73, and 86 is an obtuse triangle.

The Pythagorean Theorem states that the square of the length of the hypotenuse (the side opposite the right angle) in a right triangle is equal to the sum of the squares of the lengths of the other two sides, can be used to determine whether the triangle is right, acute, or obtuse.

In an acute triangle, the square of the hypotenuse length is less than the sum of the squares of the other two sides; in an obtuse triangle, the square of the hypotenuse length is greater than the sum of the squares of the other two sides.

Begin by calculating the square of each side:

\(44^2 = 1936\)

\(73^2 = 5329\)

\(86^2 = 7396\)

Let us now see if the triangle fulfils the Pythagorean Theorem:

1936 + 5329 = 7265

We know the triangle is not obtuse because 7265 is less than 7396.

1936 + 7396 = 9332

We know the triangle is not acute because 9332 is greater than 5329.

5329 + 7396 = 12725

We know the triangle is obtuse because 12725 is greater than 7265 but less than 9332.

As a result, the triangle with sides 44, 73, and 86 is obtuse.

The line of reflection of the given image is:

A reflection across y = -3

A line of reflection is a line that lies between two identical mirror images, so the distance of any point of one figure from the line will equal the distance of the same point of the mirror image (flipped figure).

The definition above tells us that if we are given two images, such as mirror images of each other, the line of reflection can be determined by calculating the midpoint from any two points of the figures.

Looking at the given image, the center point of the mirror images is seen as y = -3

By finding the equations for the length of the candles as a function of time, we will see that the answer is 3.27 hours.

Here we assume that:

Both candles have the same original length L, and both decrease a constant rate.

Candle 1 is consumed in 6 hours, so it is consumed at a rate of:

L/6h.

This means that after a time t in hours, the length of candle 1 is:

L₁(t) = L - (L/6h)*t

For candle 2, the rate is:

L/9h

And the function for the length of candle 2 is:

L₂(t) = L - (L/9h)*t

Now we want to find the value of t such that:

L₂(t) = 3*L₁(t)

So we just solve:

L - (L/9h)*t = 3*(L - (L/6h)*t)

L - (L/9h)*t = 3L - (L/2h)*t

(L/2h)*t -  (L/9h)*t = 3L - L = 2L

(5.5L/9h)*t = 2L

t = 2*(9h/5.5) = 3.27 h

After 3.27 hours, candle 2 will have 3 times the wax that candle 1 has.

Answer: 27 Dresses and 50 Pants

Step-by-step explanation:

If she sold 9 pairs of pants and

9 x 2 = 18

18 + 9 = 27

20 + 10 = 30

30 + 20 = 50

Evelyn sold 9 dresses and 20 pairs of pants on Friday, and on Saturday, she sold 18 dresses and 30 pairs of pants.

Evelyn's sales of dresses and pants over two days, Friday and Saturday. We'll use some mathematical expressions and reasoning to find out how many dresses Evelyn sold on each day.

Let's start by assigning some variables to represent the number of dresses and pants Evelyn sold on Friday and Saturday. We'll use "F" for Friday and "S" for Saturday. So, let \(D_F\) be the number of dresses sold on Friday, \(D_S\) be the number of dresses sold on Saturday, \(P_F\) be the number of pants sold on Friday, and \(P_S\) be the number of pants sold on Saturday.

According to the problem, on Friday, Evelyn sold 9 dresses, which can be expressed as:

\(D_F\) = 9

She also sold 20 pairs of pants on Friday:

\(P_F\) = 20

Now, let's move on to Saturday's sales. It says she sold twice as many dresses as Friday, which means the number of dresses on Saturday is double that of Friday's sales:

\(D_S = 2 * D_F\)

Additionally, she sold 10 more pairs of pants on Saturday compared to Friday:

\(P_S = P_F + 10\)

We already know that \(D_F = 9\), so we can find the number of dresses sold on Saturday by substituting this value into the equation for \(D_S\):

\(D_S = 2 * 9 = 18\)

Next, we'll calculate the number of pants sold on Saturday using the given information. Since \(P_F = 20\), we can find \(P_S\):

\(P_S = 20 + 10 = 30\)

So, to summarize, Evelyn sold 9 dresses and 20 pairs of pants on Friday, and on Saturday, she sold 18 dresses and 30 pairs of pants.

Answer:

Step-by-step explanation:

I just did process of elimination, the line crosses the y-axis through a positive area, and all the other answers had a negative y-intercept, so it couldn't be any of those.

The midpoints are not the same, indicating that the diagonals PR and QS do not bisect each other.Based on these calculations, we can conclude that the quadrilateral formed by the given points P, Q, R, and S is not a parallelogram.

To determine if the quadrilateral formed by the points P(-4, 2), Q(6, 4), R(11, -2), and S(2, -3) is a parallelogram, we need to examine its properties.

A quadrilateral is a parallelogram if opposite sides are parallel. In addition, we can also check if the diagonals bisect each other.First, let's calculate the slopes of the sides PQ, QR, RS, and SP:

Slope of PQ = (4 - 2) / (6 - (-4)) = 2/10 = 1/5

Slope of QR = (-2 - 4) / (11 - 6) = -6/5

Slope of RS = (-3 - (-2)) / (2 - 11) = -1/9

Slope of SP = (2 - (-3)) / (-4 - 2) = 5/6

We observe that the slopes of opposite sides are not equal. Therefore, the sides PQ and RS are not parallel, and the sides QR and SP are not parallel.Additionally, we can calculate the midpoint of the diagonals PR and QS:

Midpoint of PR = ((-4 + 11) / 2, (2 - 2) / 2) = (3.5, 0)

Midpoint of QS = ((6 + 2) / 2, (4 - 3) / 2) = (4, 0.5).

The length of z in the triangle is 97 inches.

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

Therefore, let's find the side z of the triangle XYZ using sine law as follows:

a / sin A = b / sin B = c / sin C

Hence,

500 / sin 117 = z / sin 10

cross multiply

500 sin 10 = z sin 117

divide both sides by sin 117

z = 500 sin 10  / sin 117

z = 86.8240888335 / 0.89100652418
