Answers
The area of sector FIJ is 233.4cm².
What is the area of the sector?
The quantity of space included within the sector's perimeter is referred to as the sector's area in a circle. A sector always starts at the circle's center. The area of a circle encompassed between its two radii and the arc next to them is known as the sector of a circle.
Here, we have
Given: FI = 13cm and angle = 160°
The area of a sector is given as
= (θ/360)×π×r²
= (160/360)×π×13²
= 0.44×3.14×13²

Answer:
Yes, the company will break even at some point in time
Step-by-step explanation:
I am not sure what methodology your teacher has been using. I am going to provide a simple methodology
The polynomial function for profit is[tex]p(x) = x^3 - 4x^2 - 1[/tex]If [tex]p(x)[/tex]has at least one zero then that means it will intersect the x-axis and the company will break even(Revenue = Costs)
The zeros of [tex]p(x)[/tex] are the values of x where [tex]p(x) = 0[/tex]
So if we can find out if [tex]p(x)[/tex] ever crosses the x-axis then that would indicate that the company will break-even at some value of [tex]x[/tex] years. If not, the company will never break even.
There is a rule to determine how many zeros a polynomial will have or in other words how many times it crosses the x-axis. This is known as Descartes' Rule of Signs.
Briefly the rule states that the number of zeros can be determined by the number of sign changes in the polynomial for consecutive termsp(x) can be re-written as:
+x³ - 4x² - 1If we look at the signs we see + - -Therefore there is one sign change from + to -This means p(x) will have one zero
Therefore the company will break-even at some point
Other Notes
You can also solve for the roots of the polynomial and see how many real roots are there. In this case there is one real root at [tex]x\approx \:4.0606[/tex]. But that is a lot of workAnother way to approach this problem is to simply graph the function and see if it crosses the x axis. I have provided the graph of this function and you can see that it does cross the x-axis at [tex]x = 4.06[/tex]I hope that helps you

scientific notation is used to keep track of very small and vary large numbers during mathematical calculations. truefalse
Answers
It is true that very small and very large and small numbers can be expressed in terms of scientific notation.
What is Scientific Notation ?Scientific notation is a method of expressing numbers in terms of a decimal number between 1 and 10, but not 10 itself multiplied by a power of 10.
The general for of scientific notation is
In scientific notation, all numbers are written in the general form as
N × [tex]10^{m}[/tex]
N times ten raised to the power of m, where the exponent m is an integer, and the coefficient N is any real number. The integer m is called the order of magnitude and the real number N is called the significand.
The digit term in the scientific notation indicates the number of significant figures in the number. The exponential term only places the decimal point. As an example,
4660000 = 4.66 x 106
This number only has 3 significant figures. The zeros are not important, they are just placeholders. As another example,
0.00053 = 5.3 x 10-4
This number has 2 significant figures. The zeros are only placeholders.
Scientific Notation Rules:
While writing the numbers in the scientific notation we have to follow certain rules they are as follows:
The scientific notations are written in two parts one is the just the digits, with the decimal point placed after the first digit, followed by multiplication with 10 to a power number of decimal point that puts the decimal point where it should be.
If the given number is greater than 1 and multiples of 10 then the decimal point has to move to the left, and the power of 10 will be positive
Example: Scientific notation for 8000 will be 8 × 103.
If the given number is smaller than 1 means in the form of decimal numbers, then the decimal point has to move to the right, and the power of 10 will be negative.
Example: Scientific notation for 0.008 will be 8 × 0.001 or 8 × 10-3.

Write the equation in standard form for the circle passing through (–
8,2) centered at the origin.
Answers
The standard form for a circle is (x - h)2 + (y - k)2 = r2, where (h, k) is the center and r is the radius. Since the radius is not given, we need to plug in the information given. Since the center is at the origin, this is the point (0, 0). Since another point on the circle is (6, 8), that is the (x, y) value. So let's plug it into the equation:
(8 - 0)2 + (8 - 0)2 = r2 --> 82 + 82 = r2 --> 100 = r2 --> 10 = r.
Since r = 10 and the center is (0, 0), the standard form equation of this circle is (x - 0)2 + (y - 0)2 = 102 or just x2 + y2 = 100.
What is radius?In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the latin radius, meaning ray but also the spoke of a chariot wheel.A radius is a straight line from the center of a circle to the circumference of a circle.

flight of a rocket the altitude in feet attained by a model rocket t seconds into flight is given by the function h(t). find the maximum altitude (in ft) attained by the rocket. (round your answer to the nearest foot.) h(t)
Answers
the maximum altitude attained by the rocket is 300 ft (rounded to the nearest foot) with time.
To find the maximum altitude attained by the rocket, we need to find the vertex of the function h(t). We can do this by taking the derivative of the function and setting it equal to 0.
h'(t) = -32t + 300
Setting h'(t) = 0, we get
-32t + 300 = 0
32t = 300
t = 300/32
hence the time t ≈ 9.375
Now, we can substitute the value of t in the original equation h(t) to get the maximum altitude attained by the rocket.
h(9.375) = -16(9.375)2 + 300(9.375)
h(9.375) = 300 ft
Therefore, the maximum altitude attained by the rocket is 300 ft (rounded to the nearest foot).
The complete question is :
flight of a rocket the altitude in feet attained by a model rocket t time seconds into flight is given by the function h(t). find the maximum altitude (in ft) attained by the rocket. (round your answer to the nearest foot.) h(t)= -16t2 + 300t

Is △XYZ equilateral, isosceles, or neither? Explain your reasoning. (Make sure to include how/why you know which of these categories the triangle falls into!)
Answers
Answer:
equilateral
Step-by-step explanation:
You want to know if the given triangle with angles marked (2x)°, (2x)°, and (3x-30)° is equilateral, isosceles, or neither.
AnglesOn the face of it, the triangle is at least isosceles, as two angles are marked identically as (2x)°.
When we apply the angle sum theorem, we find ...
(2x)° +(2x)° +(3x -30)° = 180°
7x -30 = 180
7x = 210
x = 30
2x = 2(30) = 60
3x -30 = 3(30) -30 = 60
All of the angles have the same measure, 60°, so the triangle is equilateral.
Answer:
3 equal angles = equilateral triangle
Step-by-step explanation:
the sum of the interior angles in a triangle is 180°
2x + 2x + 3x - 30 = 180
7x = 210
x = 210 : 7
x = 30
find angle Y & Z2 x 30 = 60°
find angle x3 x 30 - 30 = 60

Answers
In kite wxyz where m∠zwy=43° and m∠xyw=12°, m∠wxy = 125°
Therefore the answer is 125.
A kite is a quadrilateral with pair of two adjacent equal sides. In the given kite wxyz, adjacent sides wx = wz and zy = xy
Here, from the figure it is evident that Δwyz is congruent to Δwyx as wx = wz, xy = zy and wy as common side by SSS congruent criteria. Thus
m∠xwy = m∠zwy = 43°
Now considering Δxwy, m∠xwy + m∠xyw + m∠wxy = 180° by angle sum property of triangle. Angle sum property of triangle states that the sum of interior angles of a triangle is 180°. Therefore,
m∠wxy = 180° - m∠xwy - m∠xyw
