6. Challenge Problem: One owl hoots every 3 hours, a second owl hoots every 8 hours, and
a third owl hoots every 12 hours. If they all hoot together at the start, how many times
during the next 80 hours will just two of the owls hoot together?
Answer:
9 times
Step-by-step explanation:
The least common multiple (henceforth written as LCM) of 3 and 8 is 24. Therefore, these 2 owls hoot 72/24 = 3 times. The LCM of 3 and 12 is 12. These 2 owls hoot 72/12 = 6 times. The LCM of 8 and 12 is 24. These 2 owls hoot 72/24 = 3 times. Altogether, these owls hoot the LCM of 3, 8, AND 12, or 72/24 = 3 times. 3+3+6-3 = 9 times.
If they all hoot together at the start, 9 times during the next 80 hours will just two of the owls hoot together.
What is number theory?Number theory is the study of integers and functions of arithmetic.
One owl hoots every 3 hours.
Second owl hoots every 8 hours.
Third owl hoots every 12 hours.
If they all hoot together at the start, how many times during the next 80 hours will just two of the owls hoot together
Number theory indicates that the multiples of the periods of hooting are;
The multiples of 3 are; 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72,75, 78, 81, 82
The multiples of 8 are; 8, 16, 24, 32, 40, 48, 56, 64, 72, 80
The multiples of 12 are; 12, 24, 36, 48, 60, 72,
The least common multiple of 3 and 8 is 24, these 2 owls hoot 72/24 = 3 times.
The LCM of 3 and 12 is 12, these 2 owls hoot 72/12 = 6 times.
The LCM of 8 and 12 is 24, these 2 owls hoot 72/24 = 3 times.
Altogether, these owls hoot the LCM of 3, 8, AND 12, or 72/24 = 3 times. 3+3+6-3 = 9 times.
Therefore, 9 times during the next 80 hours will just two of the owls hoot together.

2. Abigail and Curtis Siebert: $270,000 mortgage at 7% for 20 years.
M = 270,000 * (0.5833% * (1 + 0.5833%)^240) / ((1 + 0.5833%)^240 - 1). Calculating this equation will give us the monthly mortgage payment for Abigail and Curtis Siebert.
Abigail and Curtis Siebert have a $270,000 mortgage at an interest rate of 7% for a term of 20 years.
To calculate the monthly mortgage payment, we can use the formula for an amortizing mortgage:
M = P * (r * (1 + r)^n) / ((1 + r)^n - 1),
where M is the monthly mortgage payment, P is the principal amount (loan amount), r is the monthly interest rate, and n is the total number of monthly payments.
First, we need to convert the annual interest rate to a monthly interest rate. Since there are 12 months in a year, the monthly interest rate is 7% divided by 12, which is approximately 0.5833%.
The total number of monthly payments is the term of the mortgage multiplied by 12. In this case, it's 20 years * 12 months, which equals 240 months.
Now, we can substitute the values into the formula:
M = 270,000 * (0.5833% * (1 + 0.5833%)^240) / ((1 + 0.5833%)^240 - 1).
Calculating this equation will give us the monthly mortgage payment for Abigail and Curtis Siebert.

Find the surface area of each prism. Round to the nearest tenth if necessary while doing your calculations as well as in your final answer. 360 units2 586 units2 456 units2 552 units2
Answer:
correct answer is 456 sq units.
Step-by-step explanation:
Let us have a look at the formula for Surface Area of a prism:
\(A =p \times h+2 \times B\)
Where p is the perimeter of base
h is the height of prism
and B is the base area of prism.
Given that:
h = 7.5 units
Hypotenuse of prism's base = 20 units
One of the Other sides = 12 units
Pythagorean theorem can be used to find the 3rd side of right angled base.
Square of hypotenuse = Sum of squares of other two sides
\(20^2=12^2+side^2\\\Rightarrow 400=144+side^2\\\Rightarrow side =\sqrt{256}\\\Rightarrow side =16\ units\)
Area of base = area of right angled triangle:
\(B = \dfrac{1}{2} \times \text{Base Length} \times \text{Perpendicular Length}\\\Rightarrow B = \dfrac{1}{2} \times 16\times 12 = 96\ sq\ units\)
Perimeter \(\times\) height = (12+20+16) \(\times\) 7.5 = (48) \(\times\) 7.5 = 360 sq units
Now putting the values in formula:
Surface area, A = 360+96 = 456 sq units
So, correct answer is 456 sq units.

Let f:R→S be a surjective homomorphism of rings with identity.
(a) If R is a PID, prove that every ideal in S is principal.
(b) Show by example that S need not be an integral domain.
Every ideal of S is principal when f:R⇒S be a surjective homomorphism of rings with identity.
In a homomorphism, corresponding elements of two systems behave very similarly in combination with other corresponding elements. For example, let G and H be groups. The elements of G are denoted g, g′,…, and they are subject to some operation ⊕.
In algebra, a homomorphism is a structure-preserving map between two algebraic structures of the same type (such as two groups, two rings, or two vector spaces). The word homomorphism comes from the Ancient
Let f:R⇒S be a surjective homomorphism of rings with identity.
We have to find if R is a PID, prove that every ideal in S is principal.
We know that,
Let I be the ideal of S
Since f is sufficient homomorphism.
So, f⁻¹(I) is an ideal of R.
Since R is PID so ∈ r ∈ R such that

Quadrilateral JKLM can BEST be described as
Quadrilateral JKLM has sides with equal lengths (√85), and the slopes of opposite sides are equal. However, it is not a special type of quadrilateral like a rectangle or a square.
To describe quadrilateral JKLM, let's first plot the given points J(9, 7), K(2, 1), L(0, -8), and M(7, -2) on a coordinate plane:
J(9, 7) K(2, 1)
L(0, -8) M(7, -2)
To find the slopes and lengths of each side of the quadrilateral, we can use the distance formula and the slope formula.
Slope of JK:
Slope (m) = (change in y) / (change in x)
m(JK) = (7 - 1) / (9 - 2) = 6/7
Length of JK:
Length (d) = √[(x2 - x1)^2 + (y2 - y1)^2]
d(JK) = √[(9 - 2)^2 + (7 - 1)^2] = √(49 + 36) = √85
Slope of KL:
m(KL) = (-8 - 1) / (0 - 2) = -9/2
Length of KL:
d(KL) = √[(0 - 2)^2 + (-8 - 1)^2] = √(4 + 81) = √85
Slope of LM:
m(LM) = (-2 - (-8)) / (7 - 0) = 6/7 (same as slope of JK)
Length of LM:
d(LM) = √[(7 - 0)^2 + (-2 - (-8))^2] = √(49 + 36) = √85
Slope of MJ:
m(MJ) = (7 - (-2)) / (9 - 7) = 9
Length of MJ:
d(MJ) = √[(7 - 9)^2 + (-2 - (-8))^2] = √(4 + 36) = √40
Based on the calculations, we can describe quadrilateral JKLM as follows:
The slope of JK and LM is 6/7.
The slope of KL is -9/2.
The slope of MJ is 9.
The length of each side (JK, KL, LM, MJ) is √85.
The quadrilateral is not a rectangle or a square since the slopes of opposite sides (JK and LM) are not perpendicular.

Answer:
Practical Domain: 0 ≤ g ≤ 22
Practical Range: 0 ≤ C(g) ≤ 78.32
Step-by-step explanation:
The domain is the input of the function, usually, x, but it is g in this problem.
The input here is the number of gallons you can get. The tank holds a maximum of 22 gallons, so if the tank is already full, you will get 0 gallons. If the tank is completely empty, you can get up to 22 gallons. The domain is the values of the input of the function. Since the input is from 0 gallons to 22 gallons, we get this for the domain:
Practical Domain: 0 ≤ g ≤ 22
The range is the output of the function. Usually it is f(x), but in this problem it is C(g). When you input the number of gallons into the function, the output is the cost of that number of gallons. The domain is from 0 to 22 gallons. Now we use the function to find the cost of 0 gallons and the cost of 22 gallons.
Here is the function:
C(g) = 3.56g
What is the cost of 0 gallons? In this case, g = 0.
C(0) = 3.56(0) = 3.56 × 0 = 0
0 gallons cot 0 dollars, which makes sense.
What is the cost of 22 gallons, the greatest amount of fuel you can fit in the tank?
C(g) = 3.56g
Here, g = 22.
C(22) = 3.56(22) = 3.56 × 22 = 78.32
22 gallons cost 78.32 dollars.
The range of the function is from 0 dollars to 78.32 dollars.
Practical Range: 0 ≤ C(g) ≤ 78.32

What is the equation of p(x) in vertex form?
p(x) = 2(x − 1)2 − 2
p(x) = 2(x + 1)2 − 2
p(x) = 3(x − 1)2 − 2
p(x) = 3(x + 1)2 − 2
The equation of p(x) in vertex form is;
p(x) = 9.67(x + 1.04)² - 10.25
The closest answer choice is:
p(x) = 3(x - 1)² - 2, which is not correct.
What is vertex?In the context of a quadratic function, the vertex is the highest or lowest point on the graph of the function. It is the point where the parabola changes direction. The vertex is also the point where the axis of symmetry intersects the parabola.
To find the vertex form of the quadratic function p(x), we need to first find the vertex, which is the point where the function reaches its maximum or minimum value.
To find the vertex, we can use the formula:
x = -b/2a, where a is the coefficient of the x² term, b is the coefficient of the x term, and c is the constant term.
Using the table, we can see that the highest value of p(x) occurs at x = 5, and the value is 46.
We can then use the formula to find the vertex:
x = -b/2a = -5/2a
Using the values from the table, we can set up two equations:
46 = a(5)² + b(5) + c
1 = a(0)² + b(0) + c
Simplifying the second equation, we get:
1 = c
Substituting c = 1 into the first equation and solving for a and b, we get:
46 = 25a + 5b + 1
-20 = 5a + b
Solving for b, we get:
b = -20 - 5a
Substituting b = -20 - 5a into the first equation and solving for a, we get:
46 = 25a + 5(-20 - 5a) + 1
46 = 15a - 99
145 = 15a
a = 9.67
Substituting a = 9.67 and c = 1 into b = -20 - 5a, we get:
b = -20 - 5(9.67) = -71.35
Therefore, the equation of p(x) in vertex form is:
p(x) = 9.67(x - 5)² + 1
Simplifying, we get:
p(x) = 9.67(x² - 10x + 25) + 1
p(x) = 9.67x² - 96.7x + 250.85 + 1
p(x) = 9.67x² - 96.7x + 251.85
Rounding to the nearest hundredth, we get:
p(x) = 9.67(x - 5² + 1 = 9.67(x + 1.04)² - 10.25
Therefore, the answer is:
p(x) = 9.67(x + 1.04)² - 10.25
The closest answer choice is:
p(x) = 3(x - 1)² - 2, which is not correct.

(x -1 (1/3) ) * ( x +3) * (x -4/5)
and the zeroes are located at:
x = 1.33333333... x = -3 and x = .8
Step-by-step explanation:
Answer:
\(\boxed{\sf \ \ \ f(x)=(x+3)(5x-4)(3x-4) \ \ \ }\)
Step-by-step explanation:
We need to factorise the following function
\(f(x)=15 x^3+13 x^2-80 x+48\)
-3 is a trivial solution, we can notice that f(-3)=0
so we can factorise by (x+3)
let s note a, b and c real and let s write
\(f(x)=15 x^3+13 x^2-80 x+48=(x+3)(ax^2+bx+c)\)
\((x+3)(ax^2+bx+c) = ax^3+bx^2+cx+3ax^2+3bx+3c=ax^3+(b+3a)x^2+(3b+c)x+3c\)
let s identify...
the terms in \(x^3\)
15 = a
the terms in \(x^2\)
13 = b + 3a
the terms in x
-80 = 3b+c
the constant terms
48 = 3c
so it comes, c=48/3=16, a = 15, b = 13-3*15=13-45=-32
so \(f(x)=(x+3)(15x^2-32x+16)\)
\(\Delta=32^2-4*15*16=64\)
so the roots of \((15x^2-32x+16)\) are
\(\dfrac{32-8}{15*2}=\dfrac{24}{30}=\dfrac{12}{15}=\dfrac{4}{5}\)
and
\(\dfrac{32+8}{15*2}=\dfrac{40}{30}=\dfrac{20}{15}=\dfrac{4}{3}\)

Which coordinate does not belong to the equations y = 2x + 5 or x = -3?
O (-3,7)
O (-3,1)
O (1,7)
O (0,-5)
O (-3,-1)
Answer:
O✓ (0,-5)
Step-by-step explanation:
Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
The triangles are similar. Complete the similarity statement
Answer:
ABC
Step-by-step explanation:
Answer:
YZX ~ ABC
Step-by-step explanation:
For Angle Y, there is one curved line, so you must go to the other triangle and find which angle has one curved line too, in this case that is angle A. Then, Angle Z has three curved lines, and in the other triangle, Angle B has three curved lines, so you now have AB, which only leaves C left. So your final answer is ABC.
Copy and complete the statement.
1. If HG = HK, then ____ = ____
2. If KHJ = KJH, then ____ = ____
Please add explanation as to why
Answer:
If HG = HK, then HG = HK. This statement is true by definition, as both sides of the equation are equal to the same value.
If KHJ = KJH, then KHJ = KJH. This statement is also true by definition, as both sides of the equation are equal to the same combination of letters.
Find the perimeter of this semi-circle with diameter,
d
= 38cm.
Give your answer as an expression in terms of
π
.
The perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a circle with diameter of 38 cm.
Diameter = 38 cm
The radius of the circle = 38/2 = 19 cm
Perimeter of the circle = 2πr = 2π(19) = 38π cm
Perimeter of the semicircle = 38π/2 = 19π cm
Thus, the perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.
