A kite is flying 86 ft off the ground, and its string is pulled taut. The angle of elevation of the kite is 56 degrees . Find the length of the string. Round your answer to the nearest tenth.

Answers

Answer 1
The Answer of The Question Is 112.2 Feet

The Explanation :

We can use trigonometry to solve this problem. Let's denote the length of the string as x.From the diagram, we can see that the opposite side of the triangle is the height of the kite above the ground, which is 86 ft. The angle of elevation is the angle between the hypotenuse (the string) and the horizontal.Using the definition of the tangent function, we can write:tan(56°) = opposite / adjacentwhere the opposite side is 86 ft and the adjacent side is x. Solving for x, we get:x = opposite / tan(56°) = 86 / tan(56°) ≈ 112.2 ftTherefore, the length of the string is approximately 112.2 ft when rounded to the nearest tenth.

What is a sample space?

In probability theory, sample space refers to the set of all possible outcomes of a random experiment.

For example, if we toss a coin, the sample space would consist of two possible outcomes, heads or tails. Similarly, if we roll a die, the sample space would consist of six possible outcomes, the numbers 1 through 6.

The sample space is an important concept because it allows us to define the probabilities of events. In order to calculate the probability of an event, we divide the number of outcomes that are favorable to the event by the total number of possible outcomes in the sample space.

Answer:

Step-by-step explanation:

(a)

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 7 , then

sum = 180° × (7 - 2) = 180° × 5 = 900°

(b)

since the polygon is regular then the 7 interior angles are congruent

each interior angle = 900° ÷ 7 ≈ 128.6° ( to 1 decimal place )

(c)

the sum of the exterior angles of a polygon is 360°

since the polygon is regular then the 7 exterior angles are congruent

each exterior angle = 360° ÷ 7 ≈ 51.4° ( to 1 decimal place )

Answer:

a) 900°

b) 128,6°

c) 51,4°

Step-by-step explanation:

a) s = (n - 2) × 180°

n - the number of sides (in this case, it's 7)

s - the sum of interior angles

s = (7 - 2) × 180° = 5 × 180° = 900°

.

b) In order to find the size of each angle, we have to divide the sum by the number of sides:

900° / 7 128,6°

.

c) Since the sum of exterior angles of a polygon is 360°, we can find the size of one exterior angle by dividing this sum by the number of sides:

360° / 7 51,4°

What is a dilation?

In Mathematics and Geometry, a dilation simply refers to a type of transformation which typically changes the size of a geometric object, but not its shape.

This ultimately implies that, the size of the geometric shape would be increased (stretched or enlarged) or decreased (compressed or reduced) based on the scale factor applied.

Next, we would apply a dilation to the coordinates of the pre-image by using a scale factor of 0.5 centered at the origin as follows:

Ordered pair A (-4, 3) → Ordered pair A' (-4 × 1/2, 3 × 1/2) = Ordered pair B' (-2, 1.5).

Ordered pair B (4, 4) → Ordered pair B' (4 × 1/2, 4 × 1/2) = Ordered pair B' (2, 2).

a fifth-degree polynomial can have a maximum of how many relative extrema and points of inflection? explain. a fifth-degree polynomial can have at most critical numbers, and hence relative extrema. it can have at most points of inflection.

Answers

A fifth-degree polynomial can have at most 4 critical numbers, and hence 4 relative extrema. It can have at most 3 points of inflection.

Explanation:
1. A polynomial function of degree n has (n-1) critical numbers, which are points where the derivative is either zero or undefined. Since a fifth-degree polynomial has a degree of 5, it can have at most (5-1)=4 critical numbers.

2. Relative extrema are local maximum or minimum points of the function. A relative extrema occurs at a critical number where there is a change in the sign of the first derivative (going from positive to negative or negative to positive). Since we have at most 4 critical numbers, there can be at most 4 relative extrema for a fifth-degree polynomial.
3. Points of inflection are points on the graph where the function changes its concavity (from concave up to concave down or vice versa). This occurs when the second derivative of the function changes sign. To find the points of inflection, we need to find the critical numbers of the first derivative, which is a fourth-degree polynomial (one degree less than the original polynomial). A fourth-degree polynomial has at most (4-1)=3 critical numbers.
4. Therefore, a fifth-degree polynomial can have at most 4 relative extrema and 3 points of inflection.

a boat is tied with a rope to a dock that is 12 feet tall. along the water, the boat is 16 feet from the dock. how long is the rope connecting the boa

Answers

Answer:

Step-by-step explanation:

dock is 12 ft tall

boat is 16 ft from dock

how long is the rope?

The dimensions form a right tringle.

Use Pythagorean,

a² + b² = c²

12²  +  16² = c²

144 +  256 = c²

400 = c²

√400 = √c²

20 = c

The rope is 20 ft long.

The length of the rope connecting the boat to the dock is approximately 20 feet. This can be answered by the concept of Pythagorean theorem.

To calculate the length of the rope, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the rope is the hypotenuse, and the distance between the boat and the dock (16 feet) and the height of the dock (12 feet) are the other two sides. So we have:

Rope length² = 16² + 12²

Rope length² = 256 + 144

Rope length² = 400

Rope length = √400 = 20 feet

Therefore, the length of the rope connecting the boat to the dock is approximately 20 feet

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has included probability to forecast the likelihood of certain events. The degree to which something is likely to happen is basically what probability means.

Probability is a way to gauge how likely something is to happen. Several things are difficult to forecast with absolute confidence. With it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can vary from 0 to 1, with 0 being an impossibility and 1 denoting a certainty. For pupils in Class 10, probability is a crucial subject since it teaches all the fundamental ideas of the subject. One is the probability of every event in a sample space.

we have, μ = 2.4, σ = 0.8

(a) z1 = (x1 - μ)/σ = (2 - 2.4)/0.8 = -0.5

z2 = (x2 - μ)/σ = (3 - 2.4)/0.8 = 0.75

P(2 < x < 3) = P(-0.5 < z < 0.75) = 0.4648

(b) P(x > 3) = P(z > 0.75) = 0.2266

(c) z = (1.7 - 2.4)/0.8 = -0.875

P(x < 1.7) = P(z < -0.875) = 0.1908, which is 19.08%.

Kristen’s job is to drive to sites for a construction company. Each month she is paid the same salary. She is also paid extra money for the number of miles she drives her car each month.

In March, Kristen drove 58 miles and was paid a total of $7,748.00.
In April, Kristen drove 72 miles and was paid a total of $8,532.00.
Write an equation in slope intercept form (y=mx+b) that can be used to find y, the total amount she is paid in a month if she drives x miles.

Answers

y = (46.5 - (0.5b / 58))x + b This equation allows us to plug in any value for x (the number of miles driven) and calculate Kristen's total pay for that month.

To write an equation in slope intercept form to find Kristen's total pay, we need to first determine the variable values for the equation. In this case, we know that Kristen is paid the same salary each month, so we can assign a constant value to represent her base pay. Let's call this value "b" for simplicity.

Next, we need to determine the relationship between the number of miles Kristen drives and the extra pay she receives. We can do this by calculating the rate at which she is paid per mile. To do this, we can use the formula:

Pay per mile = (Total pay - Base pay) / Number of miles driven

Using the values given in the problem, we can calculate the pay per mile for March and April as follows:

March:

Pay per mile = ($7,748.00 - b) / 58 miles

April:

Pay per mile = ($8,532.00 - b) / 72 miles

To find the overall slope of the equation, we can calculate the difference in pay per mile between March and April:

Slope = (Pay per mile for April - Pay per mile for March) / (Number of miles driven in April - Number of miles driven in March)

Slope = (($8,532.00 - b) / 72 miles) - (($7,748.00 - b) / 58 miles)) / (72 miles - 58 miles)

Simplify the equation and solve for the slope:

Slope = 46.5 - (0.5b / 58)

Now that we have the value of the slope, we can write the equation in slope intercept form:

y = mx + b

y represents Kristen's total pay, m represents the slope we just calculated, x represents the number of miles she drives, and b represents her base pay.

Putting it all together, the final equation for Kristen's total pay in a month given the number of miles she drives is:

y = (46.5 - (0.5b / 58))x + b

This equation allows us to plug in any value for x (the number of miles driven) and calculate Kristen's total pay for that month.

T=(7,−11)

Explanation:

let the midpoint be

M(4,−3)

since M is the midpoint then

SM=MT

⇒m − s = t − m

⇒t = 2m - s

⇒t = 2(4/−3)−(1/5)

⇒t = (8 /− 6)−(1/5

=(7−11)

⇒coordinates of T =(7,−11)

The coordinate of point S given the midpoint is 1, 5)

Calculating the coordinate of point S

To find the coordinates of S, we first need to use the midpoint formula to find the coordinates of M.

The midpoint formula states that the coordinates of the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) are:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

We are given that the midpoint of ST is M = (4, -3), and we know the coordinates of T are T = (7, -11).

Using the midpoint formula, we can write:

M = ((x1 + 7)/2, (y1 - 11)/2)

Solving for x1 and y1, we get:

x1 + 7 = 2 * 4 = 8

y1 - 11 = 2 * (-3) = -6

x1 = 8 - 7 = 1

y1 = -6 + 11 = 5

Therefore, the coordinates of S are S = (1, 5).

What is an expression?

It is preferable to make use of shifting integer values that can be increasing, reducing, or blocking rather than approximations generated at random. They were only able to assist one another by exchanging resources, knowledge, or answers to problems. A declaration of truth equation may include the justifications, components, and mathematical.

Here,

We need to determine a common denominator for the two fractions in order to combine the rational expressions 4/x + 10/y. Here, xy is the common factor.

As a result, 4/x can be rewritten as (4y)/xy and 10/y as (10x)/xy.

We can now combine the two fractions:

=> (10x)/xy + (4y)/xy

=> (4y + 10x)/xy

=> 2(2y + 5x)/xy

As a result, 4/x + 10/y can be expressed as 2(2y + 5x)/xy.

Shown below is a circle inside of a square, ABCD.
The circle touches the 4 sides of the square.
The area of the circle is 105cm²
Find the area of the square, ABCD.

Answers

The area of the square ABCD is approximately 420/π cm².

To find the area of the square, follow these steps:
1. Calculate the radius of the circle:
Since the area of the circle is 105 cm², you can use the formula for the area of a circle,

which is A = πr²,

where A is the area and r is the radius.
105 = πr²
Divide both sides by π:
r² = 105/π
Take the square root of both sides:
r = √(105/π)
2. Calculate the side length of the square:
Since the circle touches all 4 sides of the square, the diameter of the circle is equal to the side length of the square. The diameter is twice the radius (d = 2r), so:
d = 2√(105/π)
3. Calculate the area of the square:
Now, use the formula for the area of a square, which is A = s²,

where A is the area and s is the side length. In this case, s = d:
A = (2√(105/π))²
A = 4 * (105/π)
4. Multiply to find the area:
A = 420/π cm².

Stella has a bag that contains orange chews, apple chews, and lime chews. She performs an experiment. Stella randomly removes a chew from the bag, records the result, and returns the chew to the bag. Stella performs the experiment 21 times. The results are shown below: A orange chew was selected 12 times. A apple chew was selected 7 times. A lime chew was selected 2 times. If the experiment is repeated 1100 more times, about how many times would you expect Stella to remove a apple chew from the bag? Round your answer to the nearest whole number.

Answers

By Probability , You expect Stella to remove a apple chew from the bag

 For apple ,  Pₐ = 7/21

    For lime ,  Pi = 2/21

What is probability with and example?

Probability is a measure of how likely or likely-possible something is to happen. For instance, there is a 1 in 2 chance of receiving a head when flipping a coin, and there are 2 potential outcomes overall (a head or tail). P(heads) = 12 is what we write.

Out of 21 times that the experiment was performed

A orange chew was selected 12 times

A orange chew was selected 7 times

A lime chew was selected 2 times

then for the orange ones we have a relative frequency (that can be thought as the probability ) of

          P₀ = 12/21

    For apple ,  Pₐ = 7/21

    For lime ,  Pi = 2/21
