if the area for 2pi radians (full circumference) is --------------> 1109.80 m²
for 2pi/15----------------------------------> X
X=(2pi/15)*1109.80/2pi----------> 73.99
the answer is 73.99 m²
Answer:
74.02 square meters.
Step-by-step explanation:
We are asked to find the area of sector of circle, whose central angle is [tex]\frac{2\pi}{15}[/tex].
We will use area of sector formula to solve our given problem.
[tex]\text{Area of sector}=\frac{\theta}{2\pi}\times \pi r^2[/tex], where, r represents radius of circle.
Upon substituting our given values in above formula, we will get:
[tex]\text{Area of sector}=\frac{\frac{2\pi}{15}}{2\pi}\times \pi (18.8)^2[/tex]
Using fraction rule [tex]\frac{\frac{a}{b}}{c}=\frac{a}{bc}[/tex], we will get:
[tex]\text{Area of sector}=\frac{2\pi}{15\times 2\pi}\times \pi (18.8)^2[/tex]
[tex]\text{Area of sector}=\frac{1}{15}\times \pi \times 353.44[/tex]
[tex]\text{Area of sector}=23.5626666\times \pi[/tex]
[tex]\text{Area of sector}=74.0243004\approx 74.02[/tex]
Therefore, the area of given sector of circle is 74.02 square meters.

Answers
We have then:
The standard equation of the line is:
y-yo = m (x-xo)
m = (y2-y1) / (x2-x1)
A line of best fit crosses the y-axis at 10 and passes through the point 6 and 4
m = (4-10) / (6-0)
m = -1
(xo, yo) = (6, 4)
The line is:
y-4 = -1 (x-6)
y-4 = -x + 6
y = -x + 10
Where,
y: number of hours slept.
x: number of coffee cups.
for x = 9
y = - (9) +10
y = 1 hour

-5.8c+4.2-3.1+1.4c combine like terms to create an equivalent expression
Answers
The equivalent expression to the given expression is:
[tex]-4.4c+1.1[/tex]
Step-by-step explanation:We are given an algebraic equation in terms of the variable c as follows:
[tex]-5.8c+4.2-3.1+1.4c[/tex]
Now, we will first combine the like term i.e. the terms with the same variable term and the constant terms are combined altogether i.e. the expression is given as follows:
[tex]-5.8c+4.2-3.1+1.4c=-5.8c+1.4c+4.2-3.1[/tex]
On simplifying this expression we get :
[tex]-5.8c+4.2-3.1+1.4c=-4.4c+1.1[/tex]
Final answer:
To combine like terms in the expression -5.8c + 4.2 - 3.1 + 1.4c, we add the coefficients of the terms with 'c' and separately combine the constant terms. The simplified expression is -4.4c + 1.1.
Explanation:
To combine like terms and create an equivalent expression for -5.8c + 4.2 - 3.1 + 1.4c, we must identify and combine terms that have the same variable to the same power, which in this case are the terms with 'c' and the constant terms without variables.
Combining like terms with 'c':
-5.8c + 1.4c = -4.4c
Combining constant terms:
4.2 - 3.1 = 1.1
Equivalent Expression:
The equivalent expression by combining like terms is -4.4c + 1.1.
Jason buys a pizza for $15.59 . He also buys 6 sodas. Each soda costs the same amount. He spends $23.33 on the pizza and the sodas. Jason finds the cost of each soda by calculating (23.33 − 15.59) ÷ 6 .
Answers
Jason found that each soda costs $1.29 by calculating (23.33 - 15.59) ÷ 6.
Explanation:Jason spends $23.33 on the pizza and the sodas, and the total cost of the pizza is $15.59. Let's find out the total cost of the sodas by subtracting the cost of the pizza from the total amount spent. So, $23.33 - $15.59 = $7.74.
Now, to find the cost of each soda, we need to divide the total cost of the sodas by the number of sodas purchased. In this case, there were 6 sodas, so $7.74 ÷ 6 = $1.29.
Therefore, Jason found that each soda costs $1.29 by calculating (23.33 - 15.59) ÷ 6.
Cost of each soda (x) is approximately $1.29.
Jason buys a pizza for $15.59.
The cost of the pizza is $15.59.
He also buys 6 sodas:
The total cost of the pizza and sodas is $23.33.
Each soda costs the same amount:
Let's denote the cost of each soda as x.
He spends $23.33 on the pizza and the sodas.
The total cost can be expressed as the sum of the cost of the pizza and the cost of the sodas:
15.59+6x=23.33.
Now, Jason finds the cost of each soda by calculating (23.33 − 15.59) ÷ 6.
This expression represents the cost of each soda.
Let's calculate it:
[tex]\frac{7.74}{6} \approx 1.29[/tex]
So, Jason finds that each soda costs approximately $1.29.

The acceleration due to gravity is the constant of variation. What is the acceleration due to gravity of a falling object? 4.9 9.8 10.2 19.6
Answers
Final answer:
The acceleration due to gravity on Earth is approximately 9.80 m/s² and is symbolized as g, which represents a constant rate of acceleration for free-falling objects in the absence of air resistance.
Explanation:
The acceleration due to gravity is a constant that plays a fundamental role in physics, particularly when discussing free-fall motion. On Earth, the acceleration due to gravity of a falling object, when air resistance is negligible, is approximately 9.80 m/s². This value, denoted by the symbol g, is used to calculate various parameters in the kinematic equations of motion for an object subject only to the force of gravity.

Assuming that a sample (n = 504) has a sample standard deviation of 2.26, what is the upper bound of a 95% confidence interval if the sample mean is 2.96?
Answers
We find the standard error by dividing the standard deviation by the square root of the sample size:
[tex]\frac{\sigma}{\sqrt{n}}=\frac{2.26}{\sqrt{504}}=\frac{2.26}{22.45}=0.10[/tex]
To calculate the margin of error, we multiply the standard error by 2:
0.1(2) = 0.2
For the upper bound, we add this to the mean:
2.96+0.2 = 3.16
The upper bound of a 95% confidence interval if the sample mean is 2.96 is 3.16.and this can be determined by using the formula of standard error and margin of error.
Given :
Assuming that a sample (n = 504) has a sample standard deviation of 2.26.95% confidence interval.The sample mean is 2.96.First, evaluate the standard error by using the below formula:
[tex]\rm SE = \dfrac{\sigma}{\sqrt{n} }[/tex]
Now, put the values of n and [tex]\sigma[/tex] in the above equation in order to determine the standard error.
[tex]\rm SE = \dfrac{2.26}{\sqrt{506} }[/tex]
SE = 0.10
In order to determine the margin of error multiplies the standard error by 2.
ME = 0.1 [tex]\times[/tex] 2
ME = 0.20
Now, add the margin of error and the sample mean in order to evaluate the upper bound.
= 2.96 + 0.20b
= 3.16
The upper bound of a 95% confidence interval if the sample mean is 2.96 is 3.16.

If a ship sailed due south from Iceland to Antarctica, it would sail through an angel of rotation of about 140° around Earths center. Find this measure in radians. Then , using 3960 miles for earth radius, find how far the ship would travel.
Answers
To convert the angle in degrees to radians, multiply the angle by π and divide by 180. The ship would travel approximately 3081.23 miles.
Explanation:To find the measure in radians, we need to convert the given angle from degrees to radians. There are 2π radians in a full circle, which is equal to 360°. Therefore, to convert 140° to radians, we can use the formula: radians = (degrees × π) / 180. Substituting the given angle, we get: radians = (140 × π) / 180 = (7π / 9) radians.
Next, to find how far the ship would travel, we need to calculate the arc length. The formula for the arc length of a circle is: arc length = radius × angle in radians. Given that the radius of Earth is 3960 miles and the angle of rotation is (7π / 9) radians, we can calculate the arc length as follows: arc length = 3960 × (7π / 9) ≈ 3081.23 miles.

The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct? Explain your reason by describing both forms.
Answers
y-y₁ = m(x-x₁), where,
m = (y₂-y₁)/(x₂-x₁) is the slope of the line
(x₁,y₁) and (x₂,y₂) are the coordinates of the two points
On the other hand, the slope-intercept form is written as:
y = mx + b, where,
m is the slope of the line
b is the y-intercept
In this case, since only two points were given, the y-intercept of the line is not readily known. Thus, it is only through the point-slope form that the equation of the line can be determined. This is because it only requires the substitution of the x and y-coordinates of the points in the equation.
The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct? Explain your reason by describing both forms.
Sample Response: Both are correct. Using either form will result in the same equation. The slope-intercept form uses slope and a point to find the y-intercept. Point-slope form uses the slope and a point to solve for y to generate the equation.
