area of the segment?

Area Of The Segment?

Answers

Answer 1

Answer:

A ≈ 34.91 m²

Step-by-step explanation:

the area (A) of the sector is calculated as

A = area of circle × fraction of circle

  = πr² × [tex]\frac{40}{360}[/tex] ( r is the radius )

  = π × 10² × [tex]\frac{1}{9}[/tex]

  = [tex]\frac{100\pi }{9}[/tex]

  ≈ 34.91 m² ( to 2 decimal places )

Answer 2

Answer:

34.88m²

(round 35m²)

Step-by-step explanation:

a round angle, that of the circle, is 360°, here we have a portion of 40°, we divide 360° by 40° and we have the percentage with respect to the circle

360° : 40° = 9  

we now know that the wedge is 1/9 of the circlefind the area of ​​the whole circle having the radius (10m)

Area of Circle Formulas · Area = π × r2, where 'r' is the radius

Area = π × r2

Area = π × 10²

Area = π × 100

Area = 3.14 × 100

Area = 314 m²

now we divide by 9 and we have the area of ​​the wedge

314 : 9 = 34.88m² (round 35m²)

let r(x) = f(g(h(x))), where h(1) = 2, g(2) = 4, h'(1) = 4, g'(2) = 4, and "f '(4) = 7". find r'(1). r'(1)

Answers

Answer: To find r'(1), we need to use the chain rule of differentiation, which states that:

r'(x) = f'(g(h(x))) * g'(h(x)) * h'(x)

In this case, we know that:

h(1) = 2, g(2) = 4, h'(1) = 4, g'(2) = 4, and f '(4) = 7

Therefore:

r'(1) = f'(g(h(1))) * g'(h(1)) * h'(1) = f'(g(2)) * g'(2) * h'(1) = 7 * 4 * 4 = 112

So, the derivative of r(x) with respect to x at x = 1 is 112

The median of a sample will always equal the 50th percentile.

What is median?

The median is the value in the middle of a data set, which means that 50% of the data points have a value less than or equal to the median, and 50% of the data points have a value greater than or equal to the median. The statistical median is the number in the middle of a series of numbers. To find the median, sort each number by size; the number in the middle is the median. The median is the value in the middle of a set of data. First, organize and sort the data in ascending order from smallest to largest. Divide the number of observations by two to find the midpoint value. If there are an odd number of observations, round that number up to the nearest whole number, and the value in that position is the median.

if the image of point (x,5) is (-6, y) when it is translated by the vector t(6 -2) Find the vaue of x and y

Answers

If the image of point (x,5) is (-6, y) when it is translated by the vector t(6 -2), then the values of x = -12 and y = 3.

What is mean by translated by vector?

Vector translation is a mathematical concept that describes how an object is moved in space. It involves the use of a vector, which is a quantity that has both magnitude and direction. A vector can represent a displacement, a velocity, an acceleration, or any other physical quantity that has both magnitude and direction.

When an object is translated by a vector, it moves a certain distance in a specific direction. This is usually done by adding the vector to the current position of the object. The magnitude of the vector determines the distance of the translation, while the direction of the vector determines the direction of the translation.

Additionally, the vector can be used to rotate the object. This is done by multiplying the vector by the object’s rotation matrix. The result is the object's new orientation in space, which can be used to orient the object in a different direction.

Vector translation is used in a variety of applications, including computer graphics, robotics, and navigation systems. It i also used in mathematics and physics to represent physical phenomena, such as forces, velocities, or accelerations.

Let the point P(x,5) be translated by the vector t(6,-2).

The image of point P is (x',y') = (x+6,5-2) = (-6,y)

Therefore, x+6 = -6

=> x = -6-6 = -12

Similarly, 5-2 = y

=> y = 5-2 = 3

So the value of x is -12 and y is 3.

The length of PQ in terms of MO if ∠POQ = 120° is PQ = -x * √3/3.

Let MO = x.

Since MO is perpendicular to plane α, MP and MQ form right angles with MO.

Using the Pythagorean Theorem, we have:

MP = x * tan(30°) = x * √3/3

MQ = x * tan(60°) = x * √3

Since ∠POQ = 120°, we have:

PQ = MP * 2 * cos(120°)

a) The binomial expansion of (1+12x)^1/2 is given by:

(1+12x)^1/2 = 1^1/2 + (1/2)(1^-1/2)(12x) + (1/2)(1^-1/2)(-1/2)*(12x)^2 + ...

Binomial expression: what is it?

A polynomial with only terms is a binomial. An illustration of a binomial is x + 2, where x and 2 are two distinct terms. Additionally, in this case, x has a coefficient of 1, an exponent of 1, and a constant of 2. As a result, a binomial is a two-term algebraic expression that contains a constant, exponents, a variable, and a coefficient.

The first four terms, in ascending powers of x, are:

1, (1/2)(12x), (1/8)(12x)^2, (1/16)*(12x)^3

b) To use x=1/36 in the expansion, you would substitute x=1/36 into the expansion, and keep only the terms up to x^3 (the fourth term in the expansion). This will give an approximation of the value of (1+12x)^1/2 when x=1/36.

This will be an approximation of √12 because x=1/36 corresponds to 12x = 1 and the initial value of the expansion is 1 + 12x .

We can use this approximation to approximate square root of 12 and also for other square roots by using appropriate x values.

Here we would like to find out the value of given trigonometric ratio . A right angled triangle is given to us with perpendicular= 8 and hypotenuse= 11 . Firstly let's calculate the base using Pythagoras theorem as ,

[tex]\longrightarrow h^2=p^2+b^2\\[/tex]

[tex]\longrightarrow 11^2 = 8^2+b^2\\ [/tex]

[tex]\longrightarrow 121 = 64 + b^2\\ [/tex]

[tex]\longrightarrow b^2=121-64=57\\ [/tex]

[tex]\longrightarrow b =\sqrt{57}=7.54 \\ [/tex]

Now we know that,

[tex]\longrightarrow \tan\theta =\dfrac{p}{b}\\ [/tex]

so substitute the respective values,

[tex]\longrightarrow \tan\theta =\dfrac{8}{7.54}\\ [/tex]

[tex]\longrightarrow\underline{\underline{ \tan\theta = 1.06 \approx \boxed{1}}} [/tex]

and we are done!

Baumgartner, Prosser, and Crowell are grading a calculus exam. There is a true-false question with ten parts. Baumgartner notices that one student has only two out of the ten correct and remarks, "The student was not even bright enough to have fipped a coin to determine his answers. " "Not so clear," says Prosser. "With 340 students I bet that if they all ?ipped coins to determine their answers there would be at least one exam with two or fewer answers correct. " Crowell says, "I’m with Prosser. In fact, I bet that we should expect at least one exam in which no answer is correct if everyone is just guessing. " Who is right in all of this?

According to Bernoulli's theorem, the success rate for the situation is 0.7173.

In math Bernoulli's theorem is states that that random experiment with exactly two possible outcomes, "success" and "failure" in which the probability of success is the same every time the experiment is conducted.

In order to calculate p we must sum the possible permutations of getting 0 success of 10 trials, 1 success of 10 trials, and 2 successes of 10 trials, and divide this sum by the total possible subsets from 10 elements, then it can be written as,

=> P = (10 1) (10 2) (10 1) / 2¹⁰

When we simplify this one, then we get,

=> P = 56/1024

=> P = 0.0547

When we apply the value on Bernoulli's theorem, then we get,

=> B(340, 0.0547, 0) = ( 340 0 ) x (1/1024) x (1023/1024)³⁴⁰

When we simplify this one then we get,

=> B = 0.7173

Gabriella has a loyalty card good for a discount at her local hardware store. The item she wants to buy is priced at $34, before discount and tax. After the discount, and before tax, the price is $27. 88. Find the percent discount

Answers

The percent discount is 18%.

Now, According to the question:

Based on the given condition:

Formulate:

(34 - 27.88) ÷ 34

Calculate the sum or difference:

= 6.12/34

Convert decimal into fraction:

[tex]=\frac{612}{\frac{100}{34} }[/tex]

Divide a fraction by multiplying its reciprocal:

[tex]\frac{612}{100}[/tex] × [tex]\frac{1}{34}[/tex]

Write as a single fraction:

= 612/ (100 × 34)

Cross out the common factor:

= 18/100

= 9/50

Multiply a number to both numerator and denominator:

[tex]\frac{9}{50}[/tex] × [tex]\frac{2}{2}[/tex]

= 18/100

Rewrite a fraction with denominator equals 100 to a percentage: 18%

Hence,  the percent discount is 18%.
