Find the area of the sector in a circle whose radius is 6 and the angle measure is 140 degrees. Round your answer to the nearest hundredth.

The electrician needs approximately 296.26 feet of wire.

The links between triangle's sides and angles are studied in the mathematic discipline known as trigonometry. It entails an examination of triangle's angles, lengths, and areas as well as their angles' mathematical properties (such as sine, cosine, and tangent).

The situation described can be modeled as a right triangle, where the wire from the electric box to the pole is the hypotenuse, and the angle of elevation is one of the acute angles. Let x be the length of the wire needed in feet.

Using trigonometry, we can write:

sin(17°) = opposite / hypotenuse

where the opposite side is the height of the connection on the pole above the ground. We can solve for the hypotenuse (the length of wire needed) as follows:

hypotenuse = opposite / sin(17°)

To find the opposite side, we can use the fact that the angle of elevation is 17° and the distance from the pole to the point on the ground directly beneath the connection is 85 feet. This distance is the adjacent side of the triangle, so we can write:

tan(17°) = opposite / 85

Solving for the opposite side, we get:

opposite = 85 tan(17°)

Substituting this into the formula for the hypotenuse, we get:

hypotenuse = (85 tan(17°)) / sin(17°)

hypotenuse ≈ 296.26 feet

Therefore, the electrician needs approximately 296.26 feet of wire.

The vertex of the quadratic functions are (-3, -6), (7, 2) and  (4, 0).

The vertex of a quadratic function in the form y = a(x - h)² + k is given by the point (h, k).

To find the vertex, we need to rewrite the quadratic function in this form by completing the square.

a) y = (x + 3)² - 6:

We can rewrite this equation as y = (x - (-3))² - 6, which is in the form y = a(x - h)² + k.

Therefore, the vertex is (h, k) = (-3, -6).

b) y = (x-7)² + 2:

We can rewrite this equation as y = (x - 7)² + 2, which is in the form y = a(x - h)² + k.

Therefore, the vertex is (h, k) = (7, 2).

c) y = (x-4)²:

We can rewrite this equation as y = (x - 4)² + 0, which is in the form y = a(x - h)² + k.

Answer: the answer is d) 0.3466.

Step-by-step explanation:

Starting with the equation:

6e^(4x) - 3 = 21

Add 3 to both sides:

6e^(4x) = 24

Divide both sides by 6:

e^(4x) = 4

Take the natural logarithm of both sides:

ln(e^(4x)) = ln(4)

Use the property of logarithms that ln(e^y) = y:

4x ln(e) = ln(4)

Simplify:

4x = ln(4)

Solve for x by dividing both sides by 4:

x = (1/4) ln(4)

Using a calculator, we get:

x ≈ 0.3466

Therefore, the answer is d) 0.3466.

They form a parallelogram because opposite sides of the given points have an equal slope.

The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).

To prove that the four points (2,1), (-1,-5), (1,5), and (-2,-1) are the vertices of a parallelogram, we need to show that opposite sides are parallel.

First, we can find the slope of the line connecting (2,1) and (-1,-5):

m1 = (1 - (-5)) / (2 - (-1)) = 6/3 = 2

Next, we can find the slope of the line connecting (1,5) and (-2,-1):

m2 = (5 - (-1)) / (1 - (-2)) = 6/3 = 2

Since the slopes are the same, the line segments connecting these points are parallel.

Now, we can find the slope of the line connecting (2,1) and (1,5):

m3 = (5 - 1) / (1 - 2) = -4

Next, we can find the slope of the line connecting (-1,-5) and (-2,-1):

m4 = (-1 - (-5)) / (-2 - (-1)) = 4/3

Since the slopes are different, the line segments connecting these points are not parallel.

However, we can also see that the line connecting (1,5) and (-1,-5) has the same slope as the line connecting (-2,-1) and (2,1), which is:

m5 = (5 - (-5)) / (1 - (-1)) = 10/2 = 5

Therefore, the line segments connecting (1,5) and (-1,-5), and (-2,-1) and (2,1) are parallel.

Since opposite sides are parallel, the four points (2,1), (-1,-5), (1,5), and (-2,-1) form a parallelogram.

Therefore, they form a parallelogram because opposite sides of the given points have an equal slope.

the condition for a function's graph to pass through the origin in polar coordinates is that the function's value at θ=0 is equal to zero, while the condition for a function's graph to pass through the origin in rectangular coordinates is that the function's value at (0,0) is equal to zero.

How to solve the question?

In polar coordinates, a graph of a function passes through the origin if and only if the function's value at θ=0 is equal to zero. This is because the origin in polar coordinates represents the point (r=0, θ), where r is the distance from the origin and θ is the angle of the point with respect to the positive x-axis. When a function's value at θ=0 is equal to zero, it means that the point on the graph at θ=0 lies on the positive x-axis and has a distance of r=0 from the origin, which is the origin itself.

In contrast, a graph of a function in rectangular coordinates passes through the origin if and only if the function's value at (0,0) is equal to zero. This is because the origin in rectangular coordinates represents the point where the x and y axes intersect, and a point on the graph with coordinates (x,y) passes through the origin if and only if x=0 and y=0, which means the function's value at (0,0) is equal to zero.

In summary, the condition for a function's graph to pass through the origin in polar coordinates is that the function's value at θ=0 is equal to zero, while the condition for a function's graph to pass through the origin in rectangular coordinates is that the function's value at (0,0) is equal to zero.

The cost of the envelope and stamp may vary depending on the location and the method of delivery. In this example, we assumed that the cost of the envelope is $0.15 and the cost of the stamp is $0.39, but these values may change based on the specific circumstances.

What is cost?

Cost" is the amount of money or resources that are required to produce, acquire, or obtain something. In other words, cost refers to the expenses that are incurred in the process of acquiring or producing a good or service.

For example, the cost of producing a product may include the cost of raw materials, labor, overhead expenses, and other related costs. Similarly, the cost of acquiring a product may include the purchase price, taxes, shipping costs, and any other fees or expenses associated with the purchase. Overall, cost is a crucial factor in business and economics, as it determines the profitability of a venture and helps to make informed decisions regarding investments and pricing strategies

To find the cost of the laptop after the mail-in rebate and the cost of the envelope and stamp, we can follow these steps:

Subtract the mail-in rebate from the original price of the laptop:

$2,149.99 - $200 = $1,949.99

Add the cost of the envelope and stamp to the cost of the laptop after the mail-in rebate:

$1,949.99 + $0.15 + $0.39 = $2,090.53

Therefore, the cost of the laptop after the mail-in rebate and the cost of the envelope and stamp is $2,090.53.

To explain this calculation, we first subtract the mail-in rebate of $200 from the original price of the laptop, which gives us the price of the laptop after the rebate. Then, we add the cost of the envelope and the stamp to this price to get the total cost of the laptop after the rebate and the cost of the envelope and stamp.

Therefore, The cost of the envelope and stamp may vary depending on the location and the method of delivery. In this example, we assumed that the cost of the envelope is $0.15 and the cost of the stamp is $0.39, but these values may change based on the specific circumstances.

An equation that expresses the relationship between the lengths of the three sides is a^2 + b^2 = c^2.

In a right triangle, the side opposite the right angle is called the hypotenuse, while the other two sides are called the legs.

The relationship between the lengths of the three sides in a right triangle is described by the Pythagorean Theorem, which states that the sum of the squares of the lengths of the legs equals the square of the length of the hypotenuse.

Mathematically, this can be represented as:

a^2 + b^2 = c^2

where a and b are the lengths of the legs, and c is the length of the hypotenuse.

For the given right triangle with lengths 5, 2.2360679775, and 5.47722557505, we can plug in the values of a, b, and c to get:

5^2 + 2.2360679775^2 = 5.47722557505^2

The curve xy²=2+xy has two horizontal or vertical tangent lines, namely x = 2/3 and y = -1/3, and x = -1/3 and y = 1/3.

To find the horizontal or vertical tangent lines of the curve xy²=2+xy, we need to take the derivative with respect to x and y and solve for when the derivative equals zero.

Taking the derivative with respect to x, we get:

y^2 + 2xy(dy/dx) = y(dy/dx) + 2x

Simplifying, we get

(dy/dx)(y^2 - y) = 2x - y^2

Taking the derivative with respect to y, we get

2xy + x(dy/dy)(2y) = dy/dy + x

Simplifying, we get

(dy/dy)(x-2y) = 1-x

Setting both derivatives equal to zero, we have

(dy/dx)(y^2 - y) = 2x - y^2 ...(1)

(dy/dy)(x-2y) = 1-x ...(2)

From (2), we get

dy/dy = (1-x)/(x-2y)

Substituting into (1), we get

(1-x)/(x-2y)(y^2 - y) = 2x - y^2

Simplifying, we get

y^3 - 3xy^2 + (2x^2-1)y + x = 0

This is a cubic equation in y, which can have up to three solutions. To find the horizontal or vertical tangent lines, we need to set dy/dx = 0 or dy/dy = 0.

Setting dy/dx = 0, we get

2x - y^2 = 0

Setting dy/dy = 0, we get

x - 2y = 1

By using slope intercept , These were the two points on the line: (0,-2) and (7,2).

A line is defined by the equation y = mx + b, which is also known as the slope-intercept form. When the line is graphed, m represents the slope and b the point at which the line intersects the y-axis.

We may use the slope-intercept form of a line, which is y=mx+b where m is the slope and b is the y-intercept, to graph the line y=4/7x-2. Therefore, m=4/7 and b=-2.

These variables allow us to plot two spots along the line. Since the line crosses the y-axis at (0,-2) (the y-intercept), that location will be one of the points.

We can utilize the slope of 4/7 to locate a different point along the line. This indicates that we advance up 4 units in the y direction for every 7 units we move to the right (in the x direction). We can therefore move 7 units to the right and then 4 units up, starting at (0,-2), to reach (7,2).

So now we have two points on the line: (0,-2) and (7,2). These points can be plotted on a coordinate plane, and then a straight line can be drawn through them to create the graph.

Answer:

P = 11 + (1/2)π(11) = 11 + 5.5π = 28.279 cm

Letting π = 3.142:

P = 11 + (1/2)(3.142)(11) = 28.281 cm

Answer:

y = (1/25)x^2 - 1

Step-by-step explanation:

To begin, we can use the fact that the x-intercepts of the parabola are at (5, 0) and (-6, 0) to determine the x-intercepts form of the equation. The x-intercepts form of a parabola is given by:

(x - r)(x - s) = 0,

where r and s are the x-coordinates of the x-intercepts.

Using this form, we can write:

(x - 5)(x + 6) = 0

Expanding this equation gives:

x^2 + x - 30 = 0

Next, we use the fact that the vertex of the parabola is at (0, -1) to determine the y-intercept form of the equation. The y-intercept form of a parabola is given by:

y = a(x - h)^2 + k,

where (h, k) is the vertex.

Substituting (0, -1) into this equation gives:

y = a(x - 0)^2 - 1

Simplifying gives:

y = ax^2 - 1

Now we can use the fact that the parabola passes through the point (5, 30) to determine the value of a. Substituting x = 5 and y = 0 into the equation above gives:

0 = a(5)^2 - 1

Solving for a gives:

a = 1/25

Substituting this value of a into the equation above gives the final equation of the parabola:

y = (1/25)x^2 - 1
