Write a sinusoidal function with amplitude 4, period 3???? and
vertical shift down 8 units.
A sinusoidal function is a type of periodic function that can be written in the form y = a sin(bx + c) + d, where a is the amplitude, b is the frequency, c is the phase shift, and d is the vertical shift.
Given the parameters in the question, we can plug them into the general form of a sinusoidal function to find the specific function.
Amplitude = 4
Period = 3π
Vertical shift = -8
The period of a sinusoidal function is related to the frequency by the equation period = (2π)/b. Therefore, we can solve for b to find the frequency:
3π = (2π)/b
b = (2π)/(3π)
b = 2/3
Plugging in the given values for amplitude, frequency, and vertical shift, we get the sinusoidal function:
y = 4 sin((2/3)x) - 8
This is the sinusoidal function that satisfies the given conditions. It has an amplitude of 4, a period of 3π, and a vertical shift down 8 units.

The area of the shape formed from rectangle ABDE is 78 cm².
How to find area of a rectangle?To find the area of the compound shape, we need to find the area of rectangle ABDE and triangle BCD separately and then add them.
The rectangle ABDE has a length of 15 cm (DE) and a width of 4 cm (AB). Therefore, its area is:
Area of rectangle = length x width = 15 cm x 4 cm = 60 cm²
The triangle BCD has a base of 4 cm (BC) and a height of 9 cm (BD). Therefore, its area is:
Area of triangle = 1/2 x base x height = 1/2 x 4 cm x 9 cm = 18 cm²
Now, add the areas of the rectangle and the triangle to find the total area of the compound shape:
Total area = Area of rectangle + Area of triangle = 60 cm² + 18 cm² = 78 cm²

The sequence of transformations that maps DOG to D'O'G' is a rotation of about 90 degrees of the origin, followed by a translation of 5 units right.
What is rotation?Rotation is a physical phenomenon where an object spins around an axis. It is a type of circular motion where an object moves in a circular path around a central point.
To accomplish this transformation, first, the point representing the letter D is rotated 90 degrees clockwise around the origin so that it is now pointing in the same direction as the letter O. After that, the point representing the letter D is translated 5 units to the right, resulting in the final transformation of DOG to D'O'G'.
Thus, the sequence of transformations that maps DOG to D'O'G' is a rotation of about 90 degrees of the origin, followed by a translation of 5 units right.

1. In a dart tournament, the probabilities John,Sam and Grey will hit the target are 3/4, 1/2 and 4/5, respectively. Assuming the events each of them hits the target are independent, find the probability that
a) all three of them hit the target
b) none of them hit the target
c) only John hits the target
2. Plastic X has four red and two white marbles. Plastic Y has one green, two red and two white marbles. In a game, a die is thrown first and if the outcome is a number less than 3, a marble is chosen at random from plastic X. Otherwise, a marble is randomly chosen from plastic Y.
Draw a tree diagram to show all the possible outcomes of the game. Hence, find the probability that
a) a red marble is chosen from plastic X.
b) a white marble is chosen from plastic Y.
c) a red marble is chosen.
d) a marble is chosen from plastic Y if it is known that it is red.

1. a) The probability that all three of them hit the target is the product of their individual probabilities:
P(all three hit the target) = P(John hits the target) × P(Sam hits the target) × P(Grey hits the target)
= (3/4) × (1/2) × (4/5)
= 12/40
= 3/10
b) The probability that none of them hit the target is the product of their individual probabilities of not hitting the target:
P(none hit the target) = P(John doesn't hit the target) × P(Sam doesn't hit the target) × P(Grey doesn't hit the target)

c) The probability that a red marble is chosen is the sum of the probabilities of choosing a red marble from plastic X and from plastic Y:
P(red) = P(red from X) + P(red from Y)
= (2/9) + (4/15)
= 10/45
= 2/9
d) The probability that a marble is chosen from plastic Y if it is known that it is red is the probability of choosing a red marble from plastic Y divided by the probability of choosing a red marble:

The sides of a triangle have lengths 2, 6, and 7. What kind of triangle is it?
Answer:
Scalene triangle
Step-by-step explanation:
To determine the type of triangle, we need to compare the lengths of the sides to each other.
If all three sides have the same length, it's an equilateral triangle.
If two sides have the same length and the third is different, it's an isosceles triangle.
If all three sides have different lengths, it's a scalene triangle.
Using the lengths given, we see that all three sides have different lengths, so this is a scalene triangle.
Answer:
an obtuse triangle.
Step-by-step explanation:
To determine the type of triangle with sides of lengths 2, 6, and 7, we can use the triangle inequality theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, we can check whether this condition holds for the three sides of lengths 2, 6, and 7:
2 + 6 > 7 (True)
6 + 7 > 2 (True)
2 + 7 > 6 (True)
Since all three inequalities are true, the given lengths of 2, 6, and 7 form a valid triangle.
To determine the type of triangle, we can use the lengths of the sides and the Pythagorean theorem or trigonometric functions. For this triangle, we can use the Pythagorean theorem to find that the longest side (7) is opposite the largest angle, which is greater than 90 degrees. Therefore, this triangle is an obtuse triangle.

Find three consecutive odd integers such that the product of the second and third minus the product of the first and second is 34. (If there is no solution, enter NO SOLUTION.)
There is no solution to this problem.
To find the three consecutive odd integers, we need to use algebra. Let's first represent the three consecutive odd integers as x, x+2, and x+4. Then we can set up an equation based on the given information:
(x+2)(x+4) - (x)(x+2) = 34
Simplifying the equation gives:
x^2 + 6x + 8 - x^2 - 2x = 34
Combining like terms gives:
4x + 8 = 34
Subtracting 8 from both sides gives:
4x = 26
Dividing by 4 gives:
x = 6.5
However, since we are looking for odd integers, there is no solution to this problem. Therefore, the answer is NO SOLUTION.

A manufacturer of refrigerators must ship at least 100 refrigerators to its two West coast warehouses. Each warehouse holds a maximum of 100 refrigerators. Warehouse A holds 25 refrigerators already, while warehouse B has 20 on hand. It costs $12 to ship a refrigerator to warehouse A and $10 to ship one to warehouse B. Union rules require that at least 300 workers be hired. Shipping a refrigerator t warehouse a requires 4 workers, while shipping a refrigerator to warehouse b requires 2 workers. How many refrigerators should be shipped to each warehouse to minimize costs? what is the minimum cost? How many refrigerators should be shipped to each warehouse to minimize cost? What is the minimum cost?
The manufacturer should ship 0 refrigerators to warehouse A and 80 refrigerators to warehouse B to minimize costs. The minimum cost is $800.
The objective of the problem is to minimize the cost of shipping the refrigerators to the two warehouses while also meeting the requirements of shipping at least 100 refrigerators and hiring at least 300 workers. This can be formulated as a linear programming problem with the following decision variables:
x1 = the number of refrigerators shipped to warehouse A
x2 = the number of refrigerators shipped to warehouse B
The objective function is the total cost of shipping the refrigerators:
minimize 12x1 + 10x2
The constraints are the requirements of shipping at least 100 refrigerators, hiring at least 300 workers, and the maximum capacity of each warehouse:
x1 + x2 >= 100
4x1 + 2x2 >= 300
x1 <= 75 (100 - 25)
x2 <= 80 (100 - 20)
Using the graphical method, we can plot the constraints and find the feasible region. The optimal solution will be at one of the corner points of the feasible region.
After plotting the constraints and finding the feasible region, we can evaluate the objective function at each of the corner points to find the minimum cost. The corner points and their corresponding costs are:
(75, 0) -> 12(75) + 10(0) = $900
(0, 80) -> 12(0) + 10(80) = $800
(50, 100) -> 12(50) + 10(100) = $1700
(60, 90) -> 12(60) + 10(90) = $1740
The minimum cost is $800, which occurs when 0 refrigerators are shipped to warehouse A and 80 refrigerators are shipped to warehouse B.

The answer of the given question based on the Equation is given the solution to the given equation is n = 21/4.
What is Quadratic equation?A quadratic equation is type of equation in an algebra that involves variable (usually represented by x) that raised to the second power (i.e., squared). The general form of the quadratic equation are given,
[tex]ax^2+bx+c = 0[/tex]
The highest power of variable is 2, hence , name "quadratic".
To solve this equation, we can start by simplifying each of the terms on both sides of the equation:
3n + √(n² + 8) + 3√(n² + 8) - √(n² + 8) = 8
Combining like terms, we get:
3n + 3√(n² + 8) = 8
Subtracting 3√(n² + 8) from both sides, we get:
3n = 8 - 3√(n² + 8)
Dividing both sides by 3, we get:
n = (8/3) - (√(n² + 8)/3)
Now, we can rearrange this equation to isolate the radical term on one side of the equation:
√(n² + 8)/3 = (8/3) - n
by Squaring both the sides of equation, we get:
n² + 8 = 64/9 - (16n/3) + n²
Simplifying this equation, we get:
16n/3 = 56/9
Dividing both sides by 16/3, we get:
n = 21/4
Therefore, the solution to the given equation is n = 21/4.

Use the equation below to calculate the total cost of a payday loan for #6-8.
\Total Cost = Loan amount + finance charge ( 1 + Number of rollovers or renewals). Keep in mind, this does not include the initial loan cost, just the interest.
#6. Toby takes out a payday loan to pay for a medical bill that costs $450. The payday lender charges him $50 every two weeks. Toby has to roll over the loan 4 times before he can finally pay it off. What was the total cost of his loan?
7. Tabitha takes out a payday loan to pay for her son's emergency room bill that costs $300. The payday lender charges her $40 every two weeks. She has to roll over the loan 6 times before she can finally pay it off. What is the total cost of her loan?
8. Sariah takes out a payday loan to get a new set of tires in order to pass inspection. The bill is $500. She needs her car to get to and from work but does not have enough money in her savings to cover the bill so she takes out a payday loan. The payday loan will cost her $45 every two weeks. She has to roll over 7 times. What was the total cost of her loan?
Step-by-step explanation:
Toby's loan amount is $450 and the finance charge is $50 every two weeks. He rolls over the loan 4 times.
Total cost = $450 + ($50 x (1 + 4))
Total cost = $450 + ($50 x 5)
Total cost = $450 + $250
Total cost = $700
Therefore, the total cost of Toby's payday loan is $700.
Tabitha's loan amount is $300 and the finance charge is $40 every two weeks. She rolls over the loan 6 times.
Total cost = $300 + ($40 x (1 + 6))
Total cost = $300 + ($40 x 7)
Total cost = $300 + $280
Total cost = $580
Therefore, the total cost of Tabitha's payday loan is $580.
Sariah's loan amount is $500 and the finance charge is $45 every two weeks. She rolls over the loan 7 times.
Total cost = $500 + ($45 x (1 + 7))
Total cost = $500 + ($45 x 8)
Total cost = $500 + $360
Total cost = $860
Therefore, the total cost of Sariah's payday loan is $860
Answer:
#6.
Loan amount = $450
Finance charge = $50 every two weeks
Number of rollovers or renewals = 4
Total Cost = 450 + (50 x (1 + 4))
Total Cost = 450 + 250
Total Cost = $700
The total cost of Toby's loan is $700.
#7.
Loan amount = $300
Finance charge = $40 every two weeks
Number of rollovers or renewals = 6
Total Cost = 300 + (40 x (1 + 6))
Total Cost = 300 + 280
Total Cost = $580
The total cost of Tabitha's loan is $580.
#8.
Loan amount = $500
Finance charge = $45 every two weeks
Number of rollovers or renewals = 7
Total Cost = 500 + (45 x (1 + 7))
Total Cost = 500 + 360
Total Cost = $860
The total cost of Sariah's loan is $860.
3x+4y=-30 2x-5y=72 find y
nvm sorry wrong answer
Answer:-12
Step-by-step explanation:
To solve for y, we can use the second equation to isolate x and substitute the result into the first equation:
2x - 5y = 72
2x = 5y + 72
x = (5y + 72)/2
Now we can substitute this expression for x into the first equation:
3x + 4y = -30
3((5y + 72)/2) + 4y = -30
Simplifying the left side:
(15/2)y + 108 + 4y = -30
Combining like terms:
(23/2)y = -138
Dividing both sides by (23/2):
y = -138 * 2/23
Simplifying:
y = -12
Therefore, the value of y that satisfies both equations is -12.

Since sin A = , we can use the Pythagorean identity to find cos A:
cos A = √(1 - sin²A) = √(1 - ( )²) = √(1 - ) = √()
Since A is in Quadrant I, both sin A and cos A are positive. Therefore, we can use the definition of secant to find sec A:

A follow-up question will appear once you have correctly answered the ques Since p(-1)=0, write p(x) in the form p(x)=(x+1)q(x).
The polynomial p(x) in the form p(x) = (x+1)q(x), where q(x) is a polynomial of degree n-1.
Algebraic expressions called polynomials include coefficients and variables. Indeterminates are another name for variables. For polynomial expressions, we can do mathematical operations like addition, subtraction, multiplication, and positive integer exponents but not division by variables.
x2+x-12 is an illustration of a polynomial with a single variable. There are three terms in this example: x2, x, and -12.
Since we know that p(-1)=0, we can use this information to substitute -1 into p(x), giving us:
p(-1) = 0
We can then rearrange this equation to get:
0 = p(-1) = (x+1)q(x)
This gives us the form of p(x) that we are looking for:
p(x) = (x+1)q(x)

Chapter 10 Test
11. Nate uses a cube shaped bead with side lengths
measuring 6mm. Each bead has a circular hole in
the middle. The diameter of the circular hole is 3mm.
[not drawn to scale]
Answer:
Step-by-step explanation:
I'm guessing you need the volume of the bead with the hole.
We need to get the volume of two objects; a cube and a cylinder. We need the cylinder for the hole.
V(square) = 6^3
V(square) = 216 mm^3
V(cylinder) = pi(r^2)(h)
pi(1.5^2)(6)
Radius is half the diameter, and 6 represents the height, since it's as long as the cube.
V(cylinder) = 42.41 or 13.5pi
We need to do V(s) - V(c) to find the volume of the bead.
216 - 13.5pi = 173.588 or 173.59 or 173.6
I hope this helps!

There are three types of triangle according to sides and angles each.
What is a triangle?The triangle is a type of polygon having three sides, angles and vertices.
Classification of triangles :-
Based on sides :-
1) Scalene triangle :- A triangle with all different measurements of sides and angles are called a Scalene triangle.
2) Isosceles triangle :- A triangle with two of the sides and angles are congruent called an Isosceles triangle.
3) Equilateral triangles :- A triangle with all the same measurements of sides and angles is called an Equilateral triangle.
Based on angles :-
1) Acute angled triangle :- A triangle with all the angles less than 90°, are called acute angled triangle.
2) Obtuse angled triangle :- A triangle with all the angles greater than 90° and less than 180°, are called Obtuse angled triangle.
3) Right angled triangle :- A triangle with one angle equals 90° is called a Right angled triangle.
