Answer:
Area of the sector = \(20\pi units^{2}\)Step-by-step explanation:
Area of a sector = \(\frac{\theta}{360} * \pi r^{2}\)
Given radius r = 10units
\(\theta = \frac{2\pi}{5}\)
\(\pi = 3.14\)
substituting the given values into the equation above;
Area of the sector = \(\frac{2\pi}{5*360} * \pi *10^{2}\)
Area of the sector \(=\frac{100\pi}{5}\)
Area of the sector = \(20\pi units^{2}\)
ABC has vertices at A(-7,8). B (7,0), and C(-5, -8) Show that point A is equidistant from the endpoints of segment BC. [3 points]

A car loan worth 800,000 pesos is to be settled by making equal monthly payments at 7% interest compounded monthly for 5 years. How much is the monthly payment? How much is the outstanding balance after 2 years?
The monthly payment for the car loan is approximately 16,216.38 pesos. The outstanding balance after 2 years is approximately 650,577.85 pesos.
To find the monthly payment for the car loan, we can use the formula for the monthly payment on a loan:
P = (r * PV) / (1 - (1 + r)^(-n))
Where:
P is the monthly payment
r is the monthly interest rate
PV is the loan amount (present value)
n is the total number of payments
In this case, the loan amount PV is 800,000 pesos, the monthly interest rate r is 7% / 12 (since the interest is compounded monthly), and the total number of payments n is 5 years * 12 months/year = 60 months.
Substituting these values into the formula, we have:
P = (0.07/12 * 800,000) / (1 - (1 + 0.07/12)^(-60))
Calculating this expression, we find that P ≈ 16,216.38 pesos.
So, the monthly payment for the car loan is approximately 16,216.38 pesos.
To find the outstanding balance after 2 years, we need to calculate the remaining balance after making monthly payments for 2 years. We can use the formula for the remaining balance on a loan:
Remaining Balance = PV * (1 + r)^n - P * ((1 + r)^n - 1) / r
Where:
PV is the loan amount (present value)
r is the monthly interest rate
n is the number of payments made
Substituting the given values into the formula, we have:
Remaining Balance = 800,000 * (1 + 0.07/12)^24 - 16,216.38 * ((1 + 0.07/12)^24 - 1) / (0.07/12)
Calculating this expression, we find that the outstanding balance after 2 years is approximately 650,577.85 pesos.
So, the outstanding balance after 2 years is approximately 650,577.85 pesos.

The average height of 2 boys are 145cm.the height of one of the boys is 140cm.what is the height of the other boy
If the average height of two boys is 145 cm and one of the boys has a height of 140 cm, then the height of the other boy is 150 cm.
Let's denote the height of the other boy as x cm. We are given that the average height of the two boys is 145 cm.
According to the concept of average, the sum of the heights of the two boys divided by 2 should equal the average height.
So we can write the equation:
(140 cm + x cm) / 2 = 145 cm
Now, let's solve for x by multiplying both sides of the equation by 2:
140 cm + x cm = 290 cm
Subtracting 140 cm from both sides, we get:
x cm = 150 cm
Therefore, the height of the other boy is 150 cm.

three vectors have equal magnitudes and make 120° with each other. we can say that
the magnitude of the resultant is \(\sqrt{2}\) times the magnitude of each individual vector, not one-third.
No, that is incorrect. The magnitude of the resultant of three vectors having equal magnitudes and making an angle of 120 degrees with each other is not one-third the magnitude of the component vectors.
The magnitude of the resultant of three vectors depends on the angle between them, as well as their magnitudes. In general, the magnitude of the resultant of three vectors can be calculated using the law of cosines, which states that the square of the magnitude of the resultant (R^2) is equal to the sum of the squares of the magnitudes of the individual vectors (\(A^2, B^2, and C^2\)), plus twice the product of the magnitudes of two of the vectors multiplied by the cosine of the angle between them.
For three vectors of equal magnitude (A = B = C = m), the magnitude of the resultant can be calculated as:
\(R^2 = 3m^2 + 2m^2 * cos(120) = 3m^2 - m^2 = 2m^2\)
\(R = \sqrt{2} * m\)
Therefore, the magnitude of the resultant is sqrt(2) times the magnitude of each individual vector, not one-third.

Sarah's charges per hour for working during the week will be $9.5.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Sarah is a nanny who bills clients at various prices depending on whether she is working during the week or on the weekend. She worked 45 hours in a single week for a salary of $902.50, of which 5 hours were on the weekend. She worked 50 hours the next week, 10 of which were on the weekend, and made 1045 dollars.
Let x be the charge per working hour and y be the number of charges per hour during the weekend. Then the equation will be
45x + 5y = 902.5 ...1
50x + 10y = 1045
25x + 5y = 522.5 ...2
Subtract equation 2 from equation 1, then we have
45x - 25x = 902.5 - 522.5
20x = 380
x = 19
And the value of y will be
25 (19) + 5y = 522.5
475 + 5y = 522.5
5y = 47.5

Based upon the central limit theorem, what is the standard deviation of a sample distribution? The sample distribution standard deviation is the population standard deviation divided by the square roo
The standard deviation of a sample distribution, according to the central limit theorem, is equal to the population standard deviation divided by the square root of the sample size.
The central limit theorem states that when independent random variables are added, their sum tends toward a normal distribution, regardless of the shape of the original variables' distribution. This holds true under certain conditions, such as a sufficiently large sample size.
To calculate the standard deviation of a sample distribution, we divide the population standard deviation by the square root of the sample size. This adjustment accounts for the fact that as the sample size increases, the variability of the sample means decreases.
In summary, the standard deviation of a sample distribution is obtained by dividing the population standard deviation by the square root of the sample size. This relationship is based on the central limit theorem, which allows us to make inferences about a population based on a sample.

.Let α,ß ∈ R ,such that 2(α -1)^3+ 3(α - 1)^2+ 6α = 0 and 2(1-ß)^3+ 3(1-ß)^2 - 6ß + 12 = 0 and α ≠ ß, also graph of y=f(x) is symmetric about point (1,0). If ∫ α ß f(x).dx = K(α+ß), then value of K is equals to.
To find the value of K, we start by analyzing the given equations and the properties of the graph of the function f(x).
From the equation 2(α - 1)^3 + 3(α - 1)^2 + 6α = 0, we can simplify and solve for α:
2α^3 - 6α^2 + 6α - 2 + 3α^2 - 6α + 3 + 6α = 0
2α^3 - 3α^2 + 3 = 0
Similarly, from the equation 2(1 - ß)^3 + 3(1 - ß)^2 - 6ß + 12 = 0, we can simplify and solve for ß:
2 - 6ß + 6ß^2 - 2ß^3 + 3 - 6ß + 12 = 0
-2ß^3 + 6ß^2 - 12ß + 17 = 0
Since α ≠ ß, these equations represent two different values for α and ß.
Next, we are given that the graph of y = f(x) is symmetric about the point (1, 0). This means that if (x, y) is a point on the graph, then (2 - x, y) is also a point on the graph. In other words, the function f(x) satisfies the symmetry property:
f(2 - x) = f(x)
Now, let's consider the integral ∫α ß f(x) dx. Since the graph of f(x) is symmetric about (1, 0), we can rewrite the integral as:
∫α ß f(x) dx = ∫1 α f(x) dx + ∫1 ß f(x) dx
Using the symmetry property, we can rewrite the second integral as:
∫1 ß f(x) dx = ∫1 2-ß f(x) dx
Combining the two integrals, we have:
∫α ß f(x) dx = ∫1 α f(x) dx + ∫1 2-ß f(x) dx
Now, if we let K = ∫1 2 f(x) dx, we can rewrite the above equation as:
∫α ß f(x) dx = ∫1 α f(x) dx + ∫1 2 f(x) dx - ∫2-ß 1 f(x) dx
Since the graph of f(x) is symmetric about (1, 0), the integral ∫2-ß 1 f(x) dx is equal to ∫1 2 f(x) dx. Therefore, we can simplify the equation further:
∫α ß f(x) dx = ∫1 α f(x) dx + ∫1 2 f(x) dx - ∫2-ß 1 f(x) dx
∫α ß f(x) dx = ∫1 α f(x) dx + ∫1 2 f(x) dx - ∫1 2 f(x) dx
∫α ß f(x) dx = ∫1 α f(x) dx
Since ∫α ß f(x) dx = K(α + ß), we can equate it to ∫1 α f(x) dx:
K(α + ß) = ∫1 α f(x) dx
Now, to find the value of K, we need to solve this equation for K. It depends on the specific form of the function f(x) and the limits of integration α and 1.

much money would you have in 4 years? Round to the nearest dollar.
Answer:
Step-by-step explanation:
Assuming that your salary is $1, your savings after each year would be:
End of year 1: $1 x 1.015 = $1.015
End of year 2: $1.015 x 1.015 = $1.03023
End of year 3: $1.03023 x 1.015 = $1.04586
End of year 4: $1.04586 x 1.015 = $1.06186
Therefore, after 4 years of saving your entire salary with a 1.5% increase each year, you would have approximately $1.06.
