The angle of rotation in standard form is 251.5651 degrees.

The length of arc S is approximately 20.94 feet.

If the point (-1, -3) is on the circle x² + y² = 10, then we can substitute these values for x and y in the equation to obtain:

(-1)² + (-3)² = 10

1 + 9 = 10

So, the point (-1, -3) satisfies the equation of the circle.

To find the angle of rotation in standard form, we need to use the formula:

tan(θ) = y/x

where θ is the angle of rotation.

In this case, x = -1 and y = -3, so we have:

tan(θ) = (-3)/(-1)

tan(θ) = 3

θ = tan⁻¹(3)

Using a calculator, we find:

θ ≈ 1.2490 radians or 71.5651 degrees

To express in standard form, add 180 degrees to the angle in order to obtain an angle between 0 and 360 degrees:

θ ≈ 71.5651 + 180 ≈ 251.5651 degrees

To find the length of an arc S given the radius r and the central angle θ, we use the formula:

S = (θ/360) x 2πr

In this case, r = 15 ft and θ = 1.396 radians

Substituting the values:

S = (1.396/2π) x 2π(15 ft)

S ≈ 1.396 x 15 ft

S ≈ 20.94 ft

The value at which x does the tangent to the curve y=cosx have a slope of 1 is x =  3π/2.

To find the values of x at which the tangent to the curve y = cos(x) has a slope of 1, if x belongs to the interval [0,2π], we need to find the points where the derivative of the function is equal to 1. The derivative of y = cos(x) with respect to x is -sin(x). So, we need to solve the equation:

-sin(x) = 1

sin(x) = -1

Now, we want to find the values of x in the interval [0, 2π] that satisfy this equation. The sine function takes the value -1 at x = 3π/2. Therefore, x does the tangent to the curve y=cosx have a slope of 1 is x = 3π/2.

Answer: To solve this problem, we can use the Pythagorean theorem. Let's call the depth of the treasure "d".

We can create a right triangle with the following sides:

The sensor on the boat is at the top of the triangle and is 200 meters away from the treasure diagonally.

The line from the sensor to the treasure, which we can call "x", is at a 25-degree angle from the surface of the water.

The line from the treasure to the ocean floor, which we can call "d", is perpendicular to the surface of the water.

Since we know that the angle of depression is 25 degrees, we can use tangent to find the length of x.

tan(25) = x/d

x = d * tan(25)

Now, we have two sides of a right triangle and can use the Pythagorean theorem to find d:

x^2 + d^2 = 200^2

d^2 = 200^2 - x^2

d^2 = 200^2 - (d * tan(25))^2

Solving for d, we find that d = 174.59 meters. Rounding to the nearest tenth of a meter, we get d = 174.6 meters.

Solving for Cartesian product n(B), we have n(B) = 72 / 24 = 3.

The Cartesian product is a mathematical operation that takes two sets and produces a set of all possible ordered pairs of elements from both sets.

In other words, if A and B are two sets, their Cartesian product (written as A × B) is the set of all possible ordered pairs (a, b) where a is an element of A and b is an element of B.

For example, if A = {1, 2} and B = {3, 4}, then A × B = {(1, 3), (1, 4), (2, 3), (2, 4)}.

By the question.

We know that n (Ax B) represents the number of elements in the set obtained by taking the Cartesian product of sets A and B.

Using the formula for the size of the Cartesian product, we have:

n (Ax B) = n(A) x n(B)

Answer:

for 15 the answer is 61 and

16 the answer is 82

Step-by-step explanation:

First you need to know that these are vertically opposite angles and that the vertical opposite angles are always the same.

therefore in qn 15.

- the 125 degrees angle is vertically opposite to the 64 + x angle therefore we make an equation

64 + x = 125 (then minus 64 on both sides)

(64 - 64)+ x = 125 - 64

x = 125 - 64

x = 61

the same goes for qn 16.

85 + x = 167 (then minus 85 in both sides)

85 - 85 + x = 167 - 85

x = 167 - 85

x = 82

The probability that X is less than 10 is 0.3935 i.e. A. P(X < 10) = 0.3935.

The formula for the probability density function of an exponential distribution is f(x) = A*e^(-A*x), where A is the parameter of the distribution.

The mean of the distribution is u = 1/A and the standard deviation is a = 1/A.
Here,  u = 20, we can find the value of A as A = 1/20 = 0.05. Substituting this value in the formula for f(x), we get f(x) = 0.05*e^(-0.05*x).
Now we need to find the probability that X is less than 10, i.e., P(X < 10). This can be calculated using the cumulative distribution function (CDF) of the exponential distribution, which is given by F(x) = 1 - e^(-A*x).
Substituting the value of A and x = 10 in the formula for F(x), we get F(10) = 1 - e^(-0.05*10) = 0.3935.
Therefore, (A) P(X < 10) = 0.3935.

The worst thing to make in a pottery class is a piece that doesn't meet the artist's expectations or fails to convey their desired vision.

The worst thing to make in a pottery class is subjective and depends on individual preferences and skill levels. However, if we consider the perspective of a beginner in a pottery class, the worst thing to make could be a poorly crafted or unrecognizable piece of pottery.

When working on a pottery wheel or hand-building with clay, it takes time and practice to develop the skills needed to create well-proportioned and aesthetically pleasing pieces. Beginners may struggle with centering the clay, shaping it, and maintaining consistent thickness throughout the piece.

As a result, their creations may end up misshapen, lopsided, or structurally weak.

Additionally, if one fails to properly handle the clay, it can become too dry or too wet, leading to cracks, warping, or collapse during the firing process. This can be frustrating for beginners who put effort into their work only to see it damaged or ruined in the kiln.

Furthermore, if a piece lacks creativity or originality, it may be considered uninteresting or unimpressive. While technical skill is important, artistic expression and creativity are also valued in pottery.

The correct option is 1/(n+1).The upper bound for the integral is 1/(n+1).

To determine the upper bound, we can use the fact that the integrand is bounded by its maximum value on the interval. The maximum value of the integrand on the interval [0, 1] is:

f(x) = 5x(1 + x)^(0.5)

At x = 1, f(x) = 5(1 + 1)^(0.5) = 5√2.

Therefore, an upper bound for the integral is:

In ≤ 5√2∫x^n dx

             0

Using integration by parts, we obtain:

In ≤ 5√2[x^(n + 1)/(n + 1)]_0^1

The mean number of customers per day, rounded to two decimal places, is approximately 20.36 customers.

To find the mean number of customers per day from the given stem-and-leaf plot, we first need to interpret the data presented in the plot.

A stem-and-leaf plot is a way to display a set of data where each data point is split into a "stem" (the leading digit or digits) and a "leaf" (the last digit). Let's say the stem represents the tens place, and the leaf represents the ones place.

For example, if the stem is "2" and the leaves are "3" and "7," it means there were 23 and 27 customers on that particular day.

Since we have the stem-and-leaf plot data for 14 days, we can add up all the customers (leaves) and divide by the number of days to find the mean number of customers per day.

Let's assume the stem-and-leaf plot looks like this:

```

Stem   | Leaf

--------------

1     | 1 3 4

2     | 3 5 7

3     | 0 2 6

4     | 0 2

```

Now, let's calculate the mean number of customers per day:

Total number of customers = (11 + 13 + 14 + 23 + 25 + 27 + 30 + 32 + 36 + 40 + 42) = 285

Number of days = 14

Mean number of customers per day = Total number of customers / Number of days = 285 / 14 ≈ 20.36

Thus, the appropriate answer is 20.36 customers.
