Find an equation of variation in which y varies directly as x and y=1 when x=0.5. Then find the value of y when x = 14.

An equation of variation is y= ___.

When x=14, the value of y is ___.

Answers

Part 1

The value of y is twice that of x, so the equation is y = 2x.

Part 2

Substituting in x = 14, we get y = 2(14) = 28.

What is a linear equation?

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0.

In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C.

Here, we have

Given: Members of a lacrosse team raised $2412.50 to go to a tournament. They rented a bus for $1072.50 and budgeted $67 per player for meals.

we have to determine the number of players the team can bring to the tournament.

So to make an equation, the bus charge would be the y-intercept (If no member went, they still paid for the bus fee) and the meals would be the slope (since it is dependent on how many members ride the bus.)

The total would add up to be 2412.50, so the equation would be:

2412.50 = 67x+1072.50

where x = the number of players the team can bring to the tournament without going outside of their budget.

After solving this, we get

2412.50 = 67x+1072.50

2412.50 - 1072.50 = 67x

1340 = 67x

x = 20

Hence, the number of players the team can bring to the tournament is 20.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Angle α in quadrant 3:

y = opposite = 21 and x = adjacent = 20

Then, hypotenuse = √( 21² + 20²)

                            = √ ( 441 + 400)

                            = sqrt( 881)

So, sin α = 21/√881

              = 21 × sqrt(881)/881

And, cos α = 20/sqrt(881) = 20sqrt(881) / 881

Since, Angle β in Quadrant 2:

Hence,  adjacent = -5 and hypotenuse = 13

Then, by Pythagorean,

y = opposite = 12

So, sin β = 12/13, cos β = -5/13

as given,

And, tan β = -13/12

Since, We know that;

sin (α + β) = sin α cos β + cos α sin β

               = 21/√881 × - 5/13 + 20/√881 × 12/13

               = 1/√881 (- 105/13 + 240/13)

               = - 1/√881 (135/13)

              = - 135/377

         

Hence, The value of sin (α + β) is,

sin (α + β) = - 135/377

x-intercept (3,0)

How did they get this answer? Somebody please help

Answers

The x-intercept of a line is the point where the line crosses the x-axis, which means that the y-coordinate of the point is zero. To find the x-intercept of the line y = (1/3)x - 1, we need to substitute y with zero and solve for x.

Here's how to do it:

Substitute y with zero:
0 = (1/3)x - 1

Add 1 to both sides:
1 = (1/3)x

Multiply both sides by 3:
3 = x

So the x-intercept of the line y = (1/3)x - 1 is (3,0). This means that the line crosses the x-axis at the point (3,0).

In conclusion, the x-intercept of the line y = (1/3)x - 1 is (3,0), which means that the line crosses the x-axis at the point (3,0).

Answer:

Step-by-step explanation:

x-intercept is where the line cuts the x-axis. That is, when y=0.

Substitute y=0 and we get:

       \(0=\frac{1}{3} x-1\)

       \(1=\frac{1}{3} x\)

       \(x=3\)

So x-intercept is the point (3,0).

What the meaning of "f is order-preserving if x < y implies f(x) < f(y)"?

What the meaning of "f is order-preserving if x &lt; y implies f(x) &lt; f(y)"?

Answers

An order-preserving function is a function that preserves the order of its inputs. In other words, if x is less than y, then f(x) will be less than f(y).

The statement "f is order-preserving if x < y implies f(x) < f(y)" means that if x is less than y, then f(x) must be less than f(y). This is a necessary condition for a function to be order-preserving. However, it is not a sufficient condition. For example, the function f(x) = x^2 is not order-preserving, because 2 < 3, but f(2) = 4 > f(3) = 9.

In summary, order-preserving functions are useful in situations where we need to preserve the order of a set of data.

Step-by-step explanation:

Carbon 14 is a radioactive isotope of carbon, the most common isotope of carbon being carbon 12. Carbon 14 is created when cosmic ray bombardment changes nitrogen 14 to carbon 14 in the upper atmosphere. The resulting carbon 14 combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis. Animals acquire carbon 14 by eating plants. When an animal or plant dies, it ceases to take on carbon 14, and the amount of isotope in the organism begins to decay into the more common carbon 12. Carbon 14 has a very long half-life, about 5730 years. That is, given a sample of carbon 14, it will take 5730 years for half of the sample to decay to carbon 12. The long half-life is what makes carbon 14 dating very useful in dating objects from antiquity.

Consider a sample of material that contains A(t) atoms of carbon 14 at time t. During each unit of time a constant fraction of the radioactive atoms will spontaneously decay into another element or a different isotope of the same element. Thus, the sample behaves like a population with a constant death rate and a zero birth rate. Make use of the model of exponential growth to construct a differential equation that models radioactive decay for carbon 14.

Solve the equation that you proposed in to find an explicit formula for A(t).

Answers

Answer:

Differential equation: \(\frac{dA}{dt} = k\cdot A(t)\), \(k < 0\), \(k = -\frac{1}{\tau}\), \(\tau > 0\).

Solution: \(A(t) = A_{o}\cdot e^{-\frac{t}{\tau} }\)

Step-by-step explanation:

Let suppose that rate of change of the amount of Carbon-14 atoms are directly proportional to the current amount of Carbon-14 atoms. That is:

\(\frac{dA}{dt}\propto A(t)\)

\(\frac{dA}{dt} = k\cdot A(t)\)

Where:

\(A (t)\) - Amount of Carbon-14 atoms, dimensionless.

\(k\) - Proportionality constant, measured in \(\frac{1}{yr}\).

\(k\) must be negative as death rate is constant and birth rate is zero. (\(k< 0\)). Dimensionally, we can rewritte this constant as following:

\(k = -\frac{1}{\tau}\)

Where \(\tau\) is the time constant (\(\tau > 0\)), measured in years.

We can find the solution of the ordinary differential equation by separating each variable:

\(\frac{dA}{dt} = -\frac{1}{\tau}\cdot A\)

\(\int {\frac{dA}{A} } = -\frac{1}{\tau} \int \, dt\)

\(\ln A(t) = -\frac{t}{\tau} + C\)

\(A(t) = e^{-\frac{t}{\tau}+C }\)

\(A(t) = e^{C}\cdot e^{-\frac{t}{\tau} }\)

\(A(t) = A_{o}\cdot e^{-\frac{t}{\tau} }\)

Where \(A_{o}\) is the initial amount of atoms of Carbon-14.

Last year, The Lakewood Times had a total of 4,770 subscribers. This year, after the paper

%

Answers

The Lakewood Times had a 30.4% increase in the number of subscribers after it was bought out.

What is the percentage increase?

Percent increase is a way of measuring how much something has increased relative to its original value. It is expressed as a percentage, and it is calculated by taking the difference between the new value and the original value, and then dividing that difference by the original value, and then multiplying by 100.

Formula: % increase = (new value - original value) / original value x 100

To find the percent increase, you can use the formula:

% increase = (new value - old value) / old value x 100

In this case, the percent increase would be:

% increase = (6201 - 4770) / 4770 x 100 = 30.4%

Hence, The Lakewood Times had a 30.4% increase in the number of subscribers after it was bought out.

The value of the missing side lengths x and y are 5√2 and 5 respectively.

What is the value of side length x and y?

The figure in the image is a right triangle.

Angle θ = 45 degree

Hypotenuse = x

Opposite to angle θ = y

Adjacent to angle θ = 5

To solve for side x and side y, we use the trigonometric ratio.

Note that:

Cosine = adjacent / hypotenuse

tangent = opposite / adjacent

Solving for x:

Cosine = adjacent / hypotenuse

Plug in the values

cos( 45 ) = 5/x

x = 5 / cos( 45 )

x = 5√2

Solving for side y:

tangent = opposite / adjacent

Plug in the values

tan( 45 ) = y/5

y = tan( 45 ) × 5

y = 5

Therefore, the value of side length x is 5 units.
