Answer:
Therefore, the shuffleboard disk will travel a distance of 4.71 meters before coming to a stop, which is less than the length of the court (14.3 meters).
Step-by-step explanation:
We can start by using the work-energy principle, which states that the net work done on an object is equal to its change in kinetic energy. In this case, we can assume that the initial kinetic energy of the disk is entirely converted to work done by friction, which causes the disk to come to a stop. The equation can be written as:
Work done by friction = Change in kinetic energy
The work done by friction can be calculated using the formula:
Work = force x distance
The force of friction can be found using the formula:
Force of friction = coefficient of friction x normal force
The normal force is equal to the weight of the disk, which can be found using the formula:
Weight = mass x gravity
Substituting the values given in the problem, we get:
Weight = mass x gravity = 0.75 kg x 9.81 m/s^2 = 7.3575 N
Force of friction = coefficient of friction x normal force = 0.34 x 7.3575 N = 2.4985 N
Work done by friction = Force of friction x distance
We can solve for the distance by rearranging the equation as:
Distance = Work done by friction / Force of friction
The initial kinetic energy of the disk can be found using the formula:
Kinetic energy = 0.5 x mass x velocity^2
Substituting the values given in the problem, we get:
Kinetic energy = 0.5 x 0.75 kg x (5.6 m/s)^2 = 11.76 J
Using the work-energy principle, we know that the work done by friction is equal to the change in kinetic energy, which is:
Work done by friction = Kinetic energy = 11.76 J
Substituting this value and the force of friction into the distance formula, we get:
Distance = Work done by friction / Force of friction = 11.76 J / 2.4985 N = 4.71 m
Therefore, the shuffleboard disk will travel a distance of 4.71 meters before coming to a stop, which is less than the length of the court (14.3 meters).

A student purchased a used car for $15,200. The value of the car depreciates exponentially at
a rate of 5.8% per year. What is the value of the car after 4 years? Show your work or

15.8%.
As a result, after fοur years οf depreciatiοn, the car is wοrth abοut $12,914.96.
Hοw dο I determine depreciatiοn?Subtract the asset's cοst frοm its scrap value (what yοu anticipate it tο be wοrth just at end οf the useful life) tο determine depreciatiοn using the straight-line technique. The quantity that can be depreciated, οr the depreciable basis, is the οutcοme. Take this amοunt and deduct it frοm the lifespan οf the asset, which is expressed in years.
This fοrmula fοr expοnentially decaying can be used tο determine the value οf a vehicle after fοur years οf depreciatiοn:
[tex]A = P * e^{(-rt)} (-rt)[/tex]
where A represents a finaI vaIue, P represents its initiaI price, r represents the yearIy depreciatiοn rate in decimaI fοrm, and t is the periοd οf time.
Inputting the specified vaIues resuIts in:
P = $15,200 (the οriginaI vaIue) (the initiaI vaIue)
Given that the annuaI depreciatiοn rate is 5.8%, r is equaI tο 0.058.
t = 4 (because we want tο find the vaIue after 4 years)
When we enter these vaIues, we οbtain:
[tex]A = $15,200 * e^{(-0.058 * 4)}[/tex]
Hence, When we condense an expression, we get:
[tex]A = $15,200 * e^{(-0.232)} (-0.232)[/tex]
A = $12,914.96

The polynomial that models the company's profit is 1.0x² + 3.5x, which represents the profit in thousands of dollars.
Define polynomial equationA polynomial equation is an algebraic equation that involves a polynomial, which is an expression consisting of variables and coefficients that are combined using addition, subtraction, multiplication, and exponentiation (raising to a power).
The polynomial that models the company's sales in thousands of dollars is simply the given sales volume polynomial:
Sales = 5.9x² + 8.5x + 4.7 (in thousands of dollars)
To find the polynomial that models the company's profit, we need to subtract the cost polynomial from the sales polynomial:
Profit = Sales - Cost
Profit = (5.9x² + 8.5x + 4.7) - (4.9x²+ 5x + 4.7)
Profit = (5.9 - 4.9)x² + (8.5 - 5)x
Profit = 1.0x²+ 3.5x

Tο find the derivative οf f(x), we will use the quοtient rule οf differentiatiοn.
Let's begin by simplifying the expression:
[tex]f(x) = [5(x^2 + 2) cot(x)]/[2 - cos(x) csc(x)][/tex]
[tex]f(x) = [5(x^2 + 2) cos(x)/sin(x)]/[2sin(x) - cos(x)][/tex]
[tex]f(x) = [5(x^2 + 2) cos(x)]/[sin(x)(2sin(x) - cos(x))][/tex]
Now we can apply the quotient rule:
[tex]f'(x) = [(5(x^2 + 2) cos(x))'sin(x)(2sin(x) - cos(x)) - (5(x^2 + 2) cos(x))(sin(x)(2sin(x) - cos(x)))']/(sin(x)(2sin(x) - cos(x))^2)[/tex]
To simplify, let's find the derivatives of the individual terms in the numerator:
[tex][(5(x^2+ 2) cos(x))'] = 10xcos(x) - 5(x^2+ 2)sin(x)[/tex]
[tex][(sin(x)(2sin(x) - cos(x)))'] = 3cos^2 (x) - 4sin^2(x)[/tex]
Now we can substitute these back into our original equation for f'(x):
[tex]f'(x) = [(10xcos(x) - 5(x^2 + 2)sin(x))sin(x)(2sin(x) - cos(x)) - (5(x^2 + 2) cos(x))(3cos^2(x) - 4sin^2 x))]/(sin(x)(2sin(x) - cos(x))^2)[/tex]
Simplifying further:
[tex]f'(x) = [10xsin(x)cos(x)(2sin(x) - cos(x)) - 5(x^2 + 2)sin^2 (x)(2sin(x) - cos(x)) - 15(x^2 + 2)cos^3(x) + 20(x^2 + 2)sin^2x)cos(x)]/(sin(x)(2sin(x) - cos(x))^2)[/tex]
[tex]f'(x) = [10xsin(x)cos(x)(2sin(x) - cos(x)) - 10(x^2 + 2)sin^3(x) + 15(x^2 + 2)cos^3(x) + 20(x^2+ 2)sin^ 2(x)cos(x)]/(sin(x)(2sin(x) - cos(x))^2)[/tex]
Therefore, the derivative of f(x) is:

Ms. Grimes walks up to a tank of water that can hold up to 12 gallons.
When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank it contains 8 gallons of water. Four minutes later the tank contains 6 gallons of water.
We can use the following formula for the rate of change of a quantity:
Rate of change = (change in quantity) / (change in time)
Given that when Jada first saw the tank, 8 gallons. Four minutes later, the amount of water in the tank decreased to 6 gallons.
So the change in the amount of water in the tank is:
change in water = 6 gallons - 8 gallons = -2 gallons
The change in time is:
change in t = 4 minutes - 0 minutes = 4 minutes
So, the rate of change of the amount of water in the tank is:
= (change in W) / (change in t)
= (-2 gallons) / (4 minutes) = -0.5 gallons/minute
Therefore,
The rate at which the amount of water in the tank is changing is -0.5 gallons/minute. This means that the amount of water in the tank is decreasing at a rate of 0.5 gallons per minute.

The measure of the sector that represents the probability of the medicine curing one person is 216°. So correct option is A.
Describe Sector?In geometry, a sector is a region of a circle enclosed by two radii and an arc. The two radii form an angle, called the central angle, which defines the boundary of the sector.
The area of a sector can be calculated using the following formula:
Area of sector = (central angle / 360) * π * r²
where:
central angle is the angle formed by the two radii
r is the radius of the circle
π is the mathematical constant pi, which is approximately 3.14159
The perimeter of a sector is the sum of the length of the arc and the length of the two radii. The length of the arc can be calculated using the formula:
Length of arc = (central angle / 360) * 2 * π * r
Sectors are often used in real-world applications, such as calculating the area of a pizza slice or the distance traveled by a car in a circular racetrack. They are also used in trigonometry to calculate angles and side lengths of triangles formed by intersecting chords and tangents in circles.
The probability of the medicine curing one person is given by P(curing) = 3/5. Since the spinner is a circle of 360°, the measure of the sector that represents the probability of the medicine curing one person is:
360° × P(curing) = 360° × 3/5 = 216°

Therefore, we cannot calculate the cost of an ounce of insulin in 2006 using this function. (a). the cost of insulin increases by 12% per year.
(b).Therefore, an ounce of insulin would have cost approximately $114.08 in 2018.
(c).Therefore, the cost of insulin increases by 12% per year.
What is function?
a function is a relationship between two sets of objects, where each object in the first set (called the domain) is associated with exactly one object in the second set (called the range). The domain and range can be any set, including numbers, geometric shapes, or other mathematical objects.
A function is typically represented by a rule or formula that describes how to map each element in the domain to an element in the range. For example, the function f(x) = 2x maps each value of x to its double, so that f(1) = 2, f(2) = 4, f(3) = 6, and so on.
The cost of insulin increases over time because the value of 1.12 is greater than 1, meaning the function's output grows with increasing t. To find the percentage increase per year, we can calculate the difference in cost between two consecutive years and divide it by the cost of the earlier year. For example, to find the percentage increase between 2010 and 2011:
[tex]c(1) - c(0) = 54(1.12) - 54 = 6.48[/tex]
Percentage increase = (6.48/54) x 100% = 12%
Therefore, the cost of insulin increases by 12% per year.
b. To find the cost of an ounce of insulin in 2018, we need to find the value of t for that year. Since t represents the number of years since 2010, we can subtract 2010 from 2018 to get:
[tex]t = 2018 - 2010 = 8[/tex]
[tex]c(8) = 54(1.12)^8 =$114.08[/tex]
Therefore, an ounce of insulin would have cost approximately $114.08 in 2018.
c. To find the cost of an ounce of insulin in 2006, we need to find the value of t for that year. Since t represents the number of years since 2010, we can subtract 2010 from 2006 to get:
[tex]t = 2006 - 2010 = -4[/tex]
However, a negative value of t is not meaningful in this context because the function assumes t represents the number of years since 2010. Therefore, we cannot calculate the cost of an ounce of insulin in 2006 using this function.

what is expression ?In mathematics, programming, or other subjects, an expression is typically a grouping of numbers, symbols, and operators that denotes a value or computation. When used to indicate a mathematical relationship or formula, an expression in mathematics can be made up of a number of different variables, operators, and digits. For instance, the statement 3x + 2y denotes a linear equation. A combination of variables, constants, operators, and functions can make up an expression in programming, which can then be evaluated to create a value. For instance, the expression 5 + 3 evaluates to 8 as an expression.
given
First, we can use De Moivre's theorem to simplify the expression:
(cis(22.5+67.5)) = (cis(22.5+67.5)) = cis(22.5+90) = I
We then have:
Cos(12) + I sin(12) = 32cis (12)
When we multiply these two outcomes, we obtain:
32i cis(90+12) = 32i cis(i * 32cis(12)) = 32i cis102
Thus, the phrase can be worded as follows:
(cis22.5) (5cis67.5) (5cis67.5) 32(cos (12) + I sin (12)) = 32i cis (102).
Using Euler's formula, cis102 can be written as follows:
102 + I sin + cos(102) = cis102 (102)
As a result, the expression can be expressed in the following standard form: -32 sin(102) + 32i cos = 32i (cos(102) + I sin(102)) (102)
The final response is thus: Z = 32i cos + 32sin(102) (102)

So, since the question wants you to find how much she makes for 12 hours of work, you multiply 16 times 12 and you should get 192.
In conclusion, Jenny makes $192 for 12 hours of work.

What does a linear equation mean in mathematics?
A linear equation is one that only has a constant and a first-order (linear) component, like y=mx+b, where m is the slope and b is the y-intercept.
Occasionally, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
The term "linear equation" refers to equations with power 1 variables. Where ax+b = 0 is one example with only one variable, where a and b are real numbers and x is the variable.
Let Total number of apples= Y
so,
Y=x + v

Here, we have
Given: Equation: 3x²+18x–21 = 0 is written in the form (x–p)²=q.
We have to find the value of q.
3x²+18x–21 = 0
3(x²+6x-7) = 0
x²+6x-7 = 0
(x+3)²-7-9 = 0
(x+3)² - 16 = 0
(x+3)² = 16
(x-p)² = q
Hence, the value of q is 16.

● Draw a tree diagram to find the solution.
• Justify mathematically that your answer is correct.
Answer:
Step-by-step explanation:
The tree that shows the correct combination of one flavor of ice cream and one topping is the the first tree.
What is tree diagram ?
A tree diagram is a tool in the fields of general mathematics, probability, and statistics that helps calculate the number of possible outcomes of an event or problem, and to cite those potential outcomes in an organized way.
Tree diagrams, also known as probability trees or decision trees, are quite versatile and may be useful in many fields, including finance.
A tree diagram lets a user start at a single point and make mutually exclusive decisions or experience mutually exclusive events to follow a path down the branches of the tree. Using a tree diagram is simple once you assign the appropriate values to each node.
From the question, and the definition it is clear that vanilla splits into fudge and caramel and chocolate to sprinkles.
Hence A is the correct option.
Ronaldo has three and three-sevenths sandwiches. He shares three-fourths of them with his family. How many sandwiches did Ronaldo share?
Ronaldo therefore feeds his family 2 and 4/7 sandwiches as he eats sandwiches that are three and three-sevenths .
what is unitary method ?A mathematical strategy for resolving proportionality issues is the unitary method. Finding the value of one unit of a quantity and utilising that value to determine the value of a different number of units of the same quantity is what this process entails. The unitary technique can be used, for instance, to determine the cost of any quantity of apples if you know that 5 apples cost $10. $10/5 = $2 would be the price of one apple. By multiplying the quantity of apples by the price of one apple, you could then calculate the price of any other number of apples. For instance, 8 apples would cost 8 x $2, or $16, to purchase.
given
Ronaldo eats sandwiches that are three and three-sevenths of a sandwich, which is an incorrect fraction:
3 3/7 = (7*3 + 3)/7 = 24/7
He divides these sandwiches into thirds and fourths among his family, making a total of:
(3/4) * (24/7) = (324)/(47) = 18/7
We can change this incorrect fraction into a mixed number because:
18/7 = 2 and 4/7
Ronaldo therefore feeds his family 2 and 4/7 sandwiches as he eats sandwiches that are three and three-sevenths .
