=3.1416... as 'pi' in your answer, otherwise use at least 3 decimal digits.
Answers
The sinusoidal function that matches the specified graph, expressed using π ≈ 3.1416 is; y ≈ 4·sin(0.628·(x + 3))
What is a sinusoidal function?A sinusoidal function is a periodic function that is based on either the sine or the cosine function.
The general form of a sinusoidal function is; y = A·cos(B·(x - C)) + D
The peak and the trough of the graph of the function indicates that the amplitude, A = (4 - (-4))/2 = 4
The vertical shift, D = (4 + (-4))/2 = 0
The period, P = 2·π/B
A cycle is completed in -0.5 - (-10.5) = 10 units of the x-value interval
P = 10 = 2·π/B
Therefore; B = π/5
When x = -8, y = 0, therefore;
0 = 4·sin((π/5)·((-8) - C)) + 0
4·sin((π/5)·((-8) - C)) = 0
sin((π/5)·((-8) - C)) = 0
(π/5)·((-8) - C) = 0
((-8) - C) = 0
C = -8
When x = 2, y = 0, therefore;
0 = 4·sin((π/5)·(2 - C)) + 0
4·sin((π/5)·(2 - C)) = 0
sin((π/5)·(2 - C)) = 0
(π/5)·(2 - C) = 0
(2 - C) = 0
C = 2
Similarly; When x = -3, y = 0, therefore; C = -3
y = 4·sin((π/5)·(x + 3))
The value C = -3, corresponds to the horizontal shift of the graph of the sine function, which is shifted 3 units to the left
The sinusoidal function, where π ≈ 3.1416 is therefore;
y ≈ 4·sin((0.628)·(x + 3))

(1,7π/6)
Answers
Answer: The Correct answer is E (2,pie/6)
Step-by-step explanation:
To find the polar coordinates of a point given its Cartesian coordinates (x, y), we can use the following formulas:
r = √(x^2 + y^2)
θ = atan2(y, x)
where r is the radial distance from the origin to the point, and θ is the angle measured counterclockwise from the positive x-axis to the line connecting the origin and the point.
Given the Cartesian coordinates (x, y) = (√3, 1), we can plug these values into the formulas to find the polar coordinates:
r = √(√3^2 + 1^2) = √(3 + 1) = 2
θ = atan2(1, √3)
Using a calculator, we can find that θ is approximately 0.5236 radians.
So, the polar coordinates of the point (√3, 1) are (r, θ) = (2, 0.5236 radians).

The sides of a triangle are 30, 64, and 90. Use the Pythagorean Theorem to determine if the triangle is right, acute, or obtuse.
Answers
Answer:
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Let's check if the triangle with sides of 30, 64, and 90 is a right triangle:
30^2 + 64^2 = 900 + 4096 = 4996
90^2 = 8100
Since 4996 is less than 8100, the triangle is not a right triangle.
In an acute triangle, all angles are less than 90 degrees. In an obtuse triangle, one angle is greater than 90 degrees.
To determine if the triangle is acute or obtuse, we need to find the largest side. The largest side is 90. Let's find the sum of the squares of the other two sides:
30^2 + 64^2 = 900 + 4096 = 4996
Since 4996 is less than 90^2, the triangle is acute.
Therefore, the triangle with sides of 30, 64, and 90 is an acute triangle.
the triangle is obtuse
Step-by-step explanation:
[tex] {90}^{2} = 8100[/tex]
[tex] {30}^{2} + {64}^{2} = 4996[/tex]
[tex] {30}^{2} + {60}^{2} < {90}^{2} [/tex]
triangle is obtuse because the square of the largest is greater than the sum of the square of the other 2 sides

Step-by-step explanation:
To find the partial sum for the sequence
[tex]\large \boxed{\mathrm{ \ 0, \ -1, \ -3, \ -6, \ -10,}}[/tex]
We first notice that the first term is
[tex]\large \boxed{\mathrm{0}}[/tex],
And each subsequent term is the sum of the previous term and the next integer in the sequence starting with [tex]-1.[/tex] Therefore, we can use the formula for the sum of an arithmetic series to find the partial sum S14:
S14 = 14/2 * (2(0) + (14-1)(-1+0)/2) = 14/2 * (13/2 * -1) = -91
Therefore, the partial sum for the sequence up to the [tex]14th[/tex] term is [tex]-91.[/tex]
Answer:
[tex]91[/tex]
Step-by-step explanation:
The partial sum of a sequence is the sum of a certain number of terms in the sequence. For the given sequence
{0, −1, −3, −6, −10, ...},
The nth term can be represented as Tn = n(n-1)/2. This means that the partial sum of the first 14 terms of the sequence, denoted by S14, can be calculated by adding up the first 14 terms using the formula: S14 = 0 + (-1) + (-3) + (-6) + (-10) + ... + T14.
Simplifying this expression using the formula for Tn, We get S14 = 91. Therefore, the partial sum for the given sequence up to the 14th term is equal to 91.

Tom made some beads and packed all the bead in 14 small boxes and 3 large boxes. She filled each small box with the same number of beads and each large box with the same number of beads. There were 4 more beads in each large box than in each small box. 7/9 of the beads made were packed in the small boxes. How many beads were there in each small box?
Answers
Answer:
Each small box has 24/17 beads.
Step-by-step explanation:
Let's call the number of beads in each small box "s" and the number of beads in each large box "l".
We know that there are 14 small boxes, so the total number of beads in the small boxes is 14s. We also know that there are 3 large boxes, so the total number of beads in the large boxes is 3l.
From the problem, we know that there are 4 more beads in each large box than in each small box, so we can write:
l = s + 4
We also know that 7/9 of the total number of beads were packed in the small boxes, so we can write:
14s + 3l = 7/9(total number of beads)
We can simplify this expression by substituting l = s + 4:
14s + 3(s + 4) = 7/9(total number of beads)
Expanding and simplifying:
17s + 12 = 7/9(total number of beads)
Now, we need one more equation to solve for s. We know that the total number of beads is equal to the sum of the beads in the small and large boxes:
total number of beads = 14s + 3(s + 4)
Simplifying:
total number of beads = 17s + 12
Now we have two equations that we can use to solve for s:
17s + 12 = 7/9(total number of beads)
total number of beads = 17s + 12
We don't know the total number of beads, but we do know that it is a multiple of both 14 and 3 (since there are 14 small boxes and 3 large boxes). The smallest multiple of both 14 and 3 is 42, so let's assume that the total number of beads is 42x, where x is some number.
Substituting 42x for "total number of beads" in the two equations:
17s + 12 = 7/9(42x)
42x = 17s + 12
Simplifying:
153s + 108 = 98x
42x = 17s + 12
Now we have two equations and two unknowns (s and x). We can solve for s in terms of x by isolating s in the second equation:
17s = 42x - 12
s = (42x - 12)/17
We can substitute this expression for s into the first equation:
17((42x - 12)/17) + 12 = 7/9(42x)
Simplifying:
42x - 12 + 12 = 14x
28x = 24
x = 24/28 = 0.857
Now we know that the total number of beads is:
42x = 42(0.857) = 36
And we know that each small box has:
s = (42x - 12)/17 = (36 - 12)/17 = 24/17
So each small box has 24/17 beads.

The diameter of a bicycle wheel is 60 centimeters. How far does the wheel travel when it makes 35 revolutions? Give your answer in. meters( Math in focus singapore math course 1 B)
Answers
Answer:
The circumference of a circle is given by the formula "C = pi x d" where "d" is the diameter and "pi" is the mathematical constant with an approximate value of 3.14.
In this problem, the diameter of the bicycle wheel is 60 centimeters, so its circumference is:
C = pi x d = 3.14 x 60 = 188.4 centimeters
When the wheel makes one revolution, it travels one circumference distance. Therefore, when the wheel makes 35 revolutions, it will travel:
distance = 35 x circumference = 35 x 188.4 = 6584 centimeters
We can convert centimeters to meters by dividing the distance by 100:
distance = 6584 ÷ 100 = 65.84 meters
Therefore, the wheel travels 65.84 meters when it makes 35 revolutions.

x =
Answers
Answer: The market demand is x = 750.
Step-by-step explanation:
Answer: The market demand is x = 750.
Explanation:
To find the market demand, we need to set the demand function equal to the supply function and solve for x:
d(x) = s(x)
600 − 0.8x = 0.4x
Combining like terms, we get:
600 = 1.2x
Dividing both sides by 1.2, we get:
x = 500
However, we need to find the positive value of x. Since x represents the quantity demanded, it cannot be negative.
Substituting x = 500 into both the demand and supply functions, we find that:
d(500) = 600 - 0.8(500) = 200
s(500) = 0.4(500) = 200
Since d(500) = s(500), x = 500 is not the market demand.
Substituting x = 750 into both the demand and supply functions, we find that:
d(750) = 600 - 0.8(750) = 0
s(750) = 0.4(750) = 300
Since d(750) = s(750), x = 750 is the market demand.
Therefore, the market demand is x = 750.

An employee is considering two job offers.
First offer: $57,000 yearly salary with an 8% matching 401k
Second offer: $63,000 yearly salary with a 4% matching 401k
Let's calculate the total value of the second offer after 4 years:
Yearly salary is : $63,000
Total gross income after 4 years: $63,000 x 4 = $252,000
The company matches 5% of the employee's salary.
So, the employee contributes 5% of $63,000 = $3,150 per year
After 4 years,
Company matches: $3,150 x 4 = $12,600
Employee contributions: $3,150 x 4 = $12,600
Total 401k contributions: $12,600 + $12,600 = $25,200
The total value of the second offer after 4 years is:
Total value: $252,000 + $25,200 = $277,200
Now, let's compare this to the total value of the first offer, which is : $255,360.
Therefore, the second job offer is better by:

Let f = x^4 − 5.
(a) Determine the Galois group of f over R.
b)Let F be the splitting field of f over Q. Show that the Galois group
AutQ(F) is a non-abelian group of order eight which is generated by automorphisms φ and σ, where φ has order four and σ order two. Prove or give a counterexample: Each intermediate field of F/Q is a Galois extension of Q.
Answers
The Galois group of f over R is isomorphic to the symmetric group S4. The given statement "Each intermediate field of F/Q is a Galois extension of Q." is true because f is separable.
The roots of f are given by
x = ±(√(5) + √(2)), ±(√(5) - √(2))
Let φ be the automorphism defined by
φ(√(5) + √(2)) = √(5) + i√(2)
φ(√(5) - √(2)) = √(5) - i√(2)
φ(-√(5) + √(2)) = -√(5) - i√(2)
φ(-√(5) - √(2)) = -√(5) + i√(2)
where i is the imaginary unit. Then φ has order four since φ⁴ is the identity automorphism. Let σ be the automorphism defined by
σ(√(5) + √(2)) = -√(5) + √(2)
σ(√(5) - √(2)) = √(5) - √(2)
σ(-√(5) + √(2)) = -√(5) - √(2)
σ(-√(5) - √(2)) = √(5) + √(2)
Then σ has order two since σ² is the identity automorphism. It can be shown that the Galois group of f over Q is generated by φ and σ. Since φ has order four and σ has order two, the Galois group is a non-abelian group of order eight.
To prove or disprove that each intermediate field of F/Q is a Galois extension of Q, we need to show that each intermediate field is a splitting field of a separable polynomial over Q. Since F is the splitting field of f over Q, any intermediate field of F/Q is also a splitting field of f over Q. Since f is separable (its roots are distinct), every intermediate field of F/Q is a Galois extension of Q, and hence a splitting field of a separable polynomial over Q. Therefore, the statement is true.

graph the piecewise function. f(x)= {3x-5 if x is less than or equal to -1. -2x+3 if -1 is less than x is less than 4. 2 if x is greater than of equal to 4.
Answers
First, let's graph the function f(x) = 3x - 5 for x ≤ -1. This is a line with slope 3 and y-intercept -5 that passes through the point (-1,-8) since the inequality includes the endpoint.
Next, let's graph the function f(x) = -2x + 3 for -1 < x < 4. This is a line with slope -2 and y-intercept 3 that passes through the point (-1,5) and (4,-5) since the inequality does not include the endpoints.
Finally, let's graph the function f(x) = 2 for x ≥ 4. This is a horizontal line at y = 2.
Now we can combine the three graphs to get the graph of the piecewise function. The graph consists of three line segments: a line segment with slope 3 from negative infinity to -1, a line segment with slope -2 from -1 to 4, and a horizontal line at y = 2 from 4 to infinity.
I hope this helps!
Answer:
Here's how to graph the piecewise function:
First, we graph the function for the first interval, which is f(x) = 3x - 5 when x ≤ -1. This is a straight line with a slope of 3 and a y-intercept of -5. Since this interval includes -1, we draw a closed circle at x = -1 to indicate that it is included in the interval. The line is decreasing as x increases.
Next, we graph the function for the second interval, which is f(x) = -2x + 3 when -1 < x < 4. This is also a straight line, but with a slope of -2 and a y-intercept of 3. Since this interval does not include -1, we draw an open circle at x = -1 to indicate that it is not included in the interval. We also draw an open circle at x = 4 to indicate that it is not included in the interval. The line is increasing as x increases.
Finally, we graph the function for the third interval, which is f(x) = 2 when x ≥ 4. This is a horizontal line at y = 2. Since this interval includes 4, we draw a closed circle at x = 4 to indicate that it is included in the interval.
When we put all three intervals together, we get a graph that looks like this:

A contractor needed a small workshop. He found a preengineered steel building advertised for $12,099. If the building is a 36-ft by 36-ft square, what is the cost of the
building per square foot?
The cost of the building per square foot is $(Round to the nearest cent as needed.)
Answers
Answer:
$9.34 per square foot
Step-by-step explanation:
You want the cost per square foot of a 36 foot square building that costs $12,099.
Cost per square footThe cost per square foot is found by dividing the cost by the number of square feet. That area is found as the square of the side length:
A = s²
A = (36 ft)² = 1296 ft²
Then the cost is ...
cost per square foot = ($12099)/(1296 ft²) ≈ $9.34/ft²
The cost of the building is about $9.34 per square foot.
