Answer:
The area of a sector can be calculated using the formula:
A = (θ/360)πr^2
where θ is the central angle measure in degrees, r is the radius, and π is the mathematical constant pi.
Substituting the given values, we get:
A = (15/360)π(11)^2
≈ 16.2 ft^2
Rounding this to the nearest tenth gives:
A ≈ 15.8 ft^2
Therefore, the area of the sector rounded to the nearest tenth is 15.8 ft^2.

What is polynomial?A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. Polynomials can have constants and variables, and they usually have multiple terms that are separated by addition or subtraction.
1. The leading coefficient of a polynomial is the coefficient of the highest degree term. In the graph, the highest degree term is x3, and it is positive. Therefore, the leading coefficient of the polynomial on the right is positive.
The degree of a polynomial is the highest power of the variable in the equation. In the graph, the highest power of the variable is 3, so the minimum degree of the polynomial is 3.
2. The number of real zeros of a polynomial is the number of times the polynomial crosses the x-axis. In the graph, the polynomial crosses the x-axis twice, so it has 2 real zeros.
The number of imaginary zeros of a polynomial is the number of times the polynomial bounces off the x-axis. In the graph, the polynomial bounces off the x-axis once, so it has 1 imaginary zero.
3. The polynomial p(x) bounces off the x-axis at x=3 because the polynomial changes direction at this point.
The polynomial p(x) crosses the x-axis at x=1 and x=5 because the polynomial intersects the x-axis at these points.

Answer: Click THANKS if you like my answer. have a good day sir/maam #keep safe
D. The x-intercepts cannot be compared because either p or q does not have an x-intercept.
The function q is a constant function and its graph is a horizontal line passing through y = -1. It does not intersect the x-axis, so it does not have an x-intercept.
The function p is a logarithmic function, and its x-intercept is the point at which the graph of p intersects the x-axis. To find the x-intercept of p, we need to set p(x) = 0 and solve for x.
log₂ (x - 1) = 0
2^0 = x - 1
1 = x - 1
x = 2
So the x-intercept of p is x = 2.
Since q does not have an x-intercept, we cannot compare the x-intercepts of p and q. Therefore, the correct answer is D.

You deposit $1000 each year into an account earning 8% compounded annually.How much will you have in the account in 10 years?
Answer:
If you deposit $1000 each year into an account earning 8% compounded annually, you will have $13,366.37 in the account in 10 years. Using the compound interest formula A = P(1 + r/n)^(nt), where A is the amount, P is the principal, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years, we can calculate the amount. Plugging in the values, we get A = 1000(1 + 0.08/1)^(1*10) = $2,159.15. Therefore, the total amount after 10 years will be $13,366.37, which is the sum of the principal and the interest earned.
Given,
Annual deposit = $1000
Rate = 8% compounded annually
Time(n) = 10 year
Amount = ?
As we know the formula ,
Amount = P(1+r/100)ⁿ
Amount = 1000(1+8/100)¹⁰
Amount = 1000(1+0.08)¹⁰
Amount =1000(1.08)¹⁰
Amount = 1000 × 2.15892
Amount = $2158.92
Hence, amount in 10year will be $2158.92
ABCD Is a rectangle that represents a park.
The lines show all the paths in the park.
The circular path is in the centre of the rectangle and has a diameter of 15m.
Calculate the shortest distance from A to C across the park,using only the lines shown.
The circumference's shortest distance between points A and C is 102.91m.
What is a rectangle?A rectangle is a quadrilateral with four right angles in the Euclidean plane.
It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal.
A square is a rectangle with four equally long sides.
As a result, a square is a particular form of rectangle since it has rectangles with equal-length sides.
So, we know that:
AC = 80 m
CD = 50 m
Apply the Pythagorean theorem to the right triangle using ADC.
AC = √AD² + CD²
AC = √80² + 50²
AC = 94.34m
The shortest path through the park from point A to point C must only follow the lines depicted in the diagram.
Hence, we must deduct AC by 15 meters in diameter.
94.34m - 15m = 79.34m
The shortest distance is 79.34 miles plus one-half a circle's circumference.
As the circle's diameter is 15 meters, the radius is 15/2 = 7.5m.
The circumference would be:
2*π*r = 47.14m
The half circumference would be:
47.14/2 = 23.57m
Then,
79.34m + 23.57m = 102.91m
Therefore, the circumference's shortest distance between points A and C is 102.91m.

What’s 4559.886 rounded to the nearest inch
Answer:
Step-by-step explanation:
Assuming that the original measurement is in millimeters, since they are commonly used in precision applications, we know that 1 millimeter is equal to 0.03937 inches. Therefore, we can convert 4559.886 millimeters to inches by multiplying by 0.03937:
4559.886 mm * 0.03937 in/mm = 179.72467632 in (rounded to 8 decimal places)
To round this to the nearest inch, we need to look at the first decimal place after the decimal point. In this case, the digit in the first decimal place is 7, which is greater than or equal to 5. Therefore, we round up to the nearest inch, which gives us:
179.72467632 in rounded to the nearest inch is 180 in.
Therefore, 4559.886 rounded to the nearest inch is 180.

The 5 ft by 8 ft dimensions of the car and the (width) 2 ft by (height) 3 ft dimensions of the chair, indicates that the vehicle can haul both chairs in one trip.
What are the dimensions of a rectangularly shaped solid?The dimensions of rectangularly shaped solid are the height, the width and the length of the solid.
The possible dimensions of the vehicle and the chair obtained from a similar online question are;
Length of the vehicle = 8 feet
Width of the vehicle = 5 feet
The height of one chair = 3 feet
The width of one chair = 2 feet
Therefore;
The width of the vehicle of 5 feet indicates that the vehicle can contain the two chairs placed side by side with their widths of 2 feet each, to get;
Width of the two chairs = 2 feet + 2 feet = 4 feet < 5 feet
The two chairs placed horizontally, such that we get;
The total length of the horizontally placed chairs = 3 feet + 3 feet = 6 feet
The combined height of the two chaires, of 6 feet is less than the length of the car which is 8 feet, therefore;
The car can haul both chairs placed horizontally in a single trip.
The vehicle could therefore be used to haul both chairs in a single trip.

3. There are 15 students in class 7 who need the school shirt of same size and 2 meter of
cloth is required to make a shirt.
(a) Find the total length of the cloth required to make the shirt to them.
(b) How many shirts can be made from a piece of cloth 9 meter long?
Convert the length of cloth required for a shirt in decimal.
1
If the length of a piece of cloth is 36.25 meter, how many meters of cloth is left? 1
Answer:
Step-by-step explanation:
(a) Since each student needs a shirt of the same size, and 2 meters of cloth is required to make one shirt, the total length of cloth required to make shirts for 15 students would be:
Total length of cloth = 15 x 2 = 30 meters
Therefore, 30 meters of cloth would be required to make shirts for 15 students.
(b) If 2 meters of cloth are required to make one shirt, then the number of shirts that can be made from 9 meters of cloth would be:
Number of shirts = 9 / 2 = 4.5 shirts
However, since we cannot make half a shirt, the actual number of shirts that can be made from 9 meters of cloth would be 4 shirts.
To convert the length of cloth required for a shirt into decimal form, we can simply divide the length in centimeters by 100. Therefore, 2 meters of cloth would be equivalent to 200 centimeters, which is 2.00 meters in decimal form.
(c) If the length of a piece of cloth is 36.25 meters, and we use 30 meters to make shirts for 15 students, then the remaining length of cloth would be:
Remaining length of cloth = 36.25 - 30 = 6.25 meters
Therefore, 6.25 meters of cloth would be left.

How far is the satellite from station A?
How High is the satellite above the ground?
Round all answers to 3 decimal places.
The distance of the satellite from station A is approximately 47 miles
The satellite is approximately 911 miles above ground
How to find the distanceLet the distance from station A to the satellite be a and the distance from the station B to the satellite be a + 48
Using trigonometry
tan 87 degrees = height of the satellite above the ground, h / a
tan 87 degrees = h / a
h = a * tan 87
while
tan 84 degrees = h / a + 48
h = (a + 48) tan 84
substituting for h
a * tan 87 = (a + 48) tan 84
a (tan 87 - tan 84) = 48 tan 84
a (9.567) = 48 tan 84
a = 48 tan 84 / 9.567
a = 47.436

Which equation can you use to find the number of chocolate bars b the counselor puts on the table?
3/4b = 3 1/4
b - 3/4 = 3 1/4
b + 3 1/4 = 3/4
b + 3/4 = 3 1/4
Answer:
The correct equation is:
b - 3/4 = 3 1/4
Explanation:
Lily used 3/4 of a chocolate bar, so the remaining chocolate bars can be found by subtracting 3/4 from the total number of chocolate bars b:
b - 3/4 = remaining chocolate bars
The problem tells us that there are 3 1/4 remaining chocolate bars, so we can substitute this value in the equation and solve for b:
b - 3/4 = 3 1/4
b = 3 1/4 + 3/4
b = 4

We can claim that after answering the above question, the As a result, angles the regular polygon has ten sides.
what are angles?An angle is a shape in Euclidean geometry that is made up of two rays, known as the angle's sides, that meet at a point in the middle known as the angle's vertex. Two rays may combine to generate an angle in the plane in which they are located. An angle is formed when two planes collide. They are known as dihedral angles. In plane geometry, an angle is a potential configuration of two rays or lines that share a termination. The English term "angle" derives from the Latin word "angulus," which means "horn." The vertex is the point at where the two rays, also known as the angle's sides, converge.
The interior angle of a regular polygon with n sides is calculated as follows:
(n-2) * 180° / n = interior angle
The internal angle of the polygon is presented to us as 144°. When we plug this into the formula, we get:
144° = (n - 2) * 180° / n
144° * n = (n - 2) * 180°
