Any qualities, quantity, or number that can be gauged or tallied qualifies as a variable. A data item is another name for a variable. Examples of variables include age, sex, company income and expenses, country of birth, capital expenditures, class grades, eye color, and vehicle kind.
Given equation is y = 2x + 24
24 is represents the entry fee in the amusement park.
where y represents the total amount of money, in dollars and cents, and a represents the number of rides Carlos goes on.
Putting x = 0 in the equation to find the total amount of money Carlos will spend if he goes on o rides:
y = (2 × 0) + 24
y = 24
Putting x = 1 in the equation to find the total amount of money Carlos will spend if he goes on 1 rides:
y = (2 × 1) + 24
y = 2 + 24
y = 26
The change in the total amount of money he will spend for every additional ride he goes on is $26 - 24 = $2
Putting x = 100 in the equation to find the total amount of money Carlos will spend if he goes on 100 rides:
y = (2 × 100) + 24
y = 200 + 24
y = 224

there are $320 available to fence in a rectangular garden. the fencing for the side of the garden facing the road cost $6 per foot and the fencing for the other three sides is $2 per foot (see picture). a. determine the objective and constraint equations b. express the quantity to be maximized as a function of x. c. find the optimal values of x and y.
To answer this question, we first need to determine the objective and constraint equations.
The objective is to maximize the area of the rectangular garden, which is given by the equation $A = xy$.
The constraint is that the total cost of the fencing must not exceed $320. In other words, we have the equation $6x + 2(y+x) \le 320$.
To express the quantity to be maximized as a function of $x$, we can simply plug in the equation for the area of the rectangular garden into the objective equation. This gives us the function $f(x) = xy = x^2y$.
To find the optimal values of $x$ and $y$, we can use the method of Lagrange multipliers. Let $\lambda$ be the Lagrange multiplier. The Lagrange function is given by
$$L(x,y,\lambda) = x^2y + \lambda(6x + 2(y+x) - 320)$$
To find the optimal values of $x$ and $y$, we need to find the values of $x$ and $y$ that maximize $L(x,y,\lambda)$. To do this, we take the partial derivatives of $L(x,y,\lambda)$ with respect to $x$ and $y$ and set them equal to 0. This gives us the equations
$$\frac{\partial L}{\partial x} = 2xy + 6\lambda = 0 \quad \text{and} \quad \frac{\partial L}{\partial y} = x^2 + 2\lambda = 0$$
We can solve these equations simultaneously to find the optimal values of $x$ and $y$. First, we can solve for $y$ in the second equation to get
$$y = -\frac{x^2}{2\lambda}$$
Substituting this expression for $y$ into the first equation, we get
$$2x \left(-\frac{x^2}{2\lambda}\right) + 6\lambda = 0 \quad \Rightarrow \quad -x^3 + 12\lambda^2 = 0$$
Since $\lambda$ cannot be 0, we can divide both sides of this equation by $-12\lambda^2$ to get
$$x^3 = 12\lambda^2 \quad \Rightarrow \quad x = \sqrt[3]{12\lambda^2}$$
Substituting this expression for $x$ into the expression for $y$, we get
$$y = -\frac{\sqrt[3]{12\lambda^2}}{2\lambda}$$
Now we need to find the value of $\lambda$ that satisfies the constraint $6x + 2(y+x) \le 320$. Substituting the expressions for $x$ and $y$ into this equation, we get
$$6\sqrt[3]{12\lambda^2} + 2\left(-\frac{\sqrt[3]{12\lambda^2}}{2\lambda} + \sqrt[3]{12\lambda^2}\right) \le 320$$
Simplifying, we get
$$-\frac{\sqrt[3]{12\lambda^2}}{2\lambda} + 10\sqrt[3]{12\lambda^2} \le 320$$
Dividing both sides by $10\sqrt[3]{12\lambda^
If t less than s and s less than r what is the relationship between the values t and r?
If t is less than s and s is less than r then the relationship between the values t and r is - t is less than r.
We are given that-
t is less than s i.e. t < s
and
s is less than r i.e. s < r
Now, let us find the relationship between the values of t and r.
t < s and s < r
this implies that - t < s < r
Hence, we get t < r.
Thus, we get that if t is less than s and s is less than r then the relationship between the values t and r is - t is less than r i.e. t < r.

The equation of the area is 308 = 2 * (10 * x) + 2 * (2 * x) + 2 * (10 * 2) + 6 * (5 * 5) - 2 * (5 * 5)
How to determine the equation?From the question, we have the following parameters that can be used in our computation:
Area = 308
The formula used to calculate area
Area = S.A of the bottom + S.A of the top - 2 * Overlap
Using the given figure, we have
S.A of the top = 6 * (5 * 5)
S.A of the bottom = 2 * (10 * x) + 2 * (2 * x) + 2 * (10 * 2)
Overlap = 2 * (5 * 5)
So, we have
308 = 2 * (10 * x) + 2 * (2 * x) + 2 * (10 * 2) + 6 * (5 * 5) - 2 * (5 * 5)

The rate at which the slope of the line is changing with respect to time is dθ/dt.
The rate at which the slope of a line is changing with respect to time is a concept in calculus that is known as the derivative. The derivative measures the rate of change of a function with respect to one of its variables. In this case, we are looking at the rate of change of the slope of the line with respect to time. The slope of a line is determined by the angle, theta, between the line and the positive x-axis. Therefore, the rate of change of the slope of the line with respect to time is equal to the rate of change of the angle, theta, with respect to time. This can be expressed as dθ/dt, where dθ represents the change in theta and dt represents the change in time. Therefore, the expression which gives the rate at which the slope of the line is changing with respect to time is dθ/dt.

solve the following trigonomic equation for 0 < theta < 2pi
cos(theta) * csc(theta) - 2cos(theta) = 0
pls help
Answer:
To solve the given trigonometric equation, we can start by isolating the cos(theta) term on one side of the equation. We can do this by dividing both sides of the equation by csc(theta):cos(theta) * csc(theta) - 2cos(theta) = 0
cos(theta) * csc(theta) / csc(theta) - 2cos(theta) / csc(theta) = 0 / csc(theta)
cos(theta) - 2cos(theta) / csc(theta) = 0Next, we can combine like terms on the left side of the equation:cos(theta) - 2cos(theta) / csc(theta) = 0
-2cos(theta) / csc(theta) + cos(theta) = 0
(1 - 2 / csc(theta)) cos(theta) = 0Since cos(theta) cannot be equal to 0 (because the angle theta is between 0 and 2pi), the only solution to this equation is:1 - 2 / csc(theta) = 0
1 = 2 / csc(theta)
csc(theta) = 2This means that the value of csc(theta) is equal to 2. To find the value of theta, we can use the inverse cosecant function (arcsec) to solve for theta:theta = arcsec(2)The value of arcsec(2) is approximately 1.047198, which is the solution to the given equation for theta.Note that this is just one solution to the equation, as there may be other solutions for theta depending on the values of the trigonometric functions. It is important to check that the solution falls within the given range of 0 < theta < 2pi.

Suppose that the probability that the dart hit the area between the square of side length 14 and the square of side length 16
The probability of the area hit by the dart between the bigger square and the smaller square is equal to 0.7656.
As given in the question,
Total number of squares present = 2
Side length of the bigger square = 16 units
Side length of the smaller square = 14 units
Area of the bigger square = ( side length )²
= ( 16 )²
= 256 square units
Area of the smaller square = ( side length )²
= ( 14 )²
= 196 square units
Here favorable outcome is represented by small square and total outcome is represented by bigger square
Probability that the given dart hit the area between the square is
= 196 / 256
= 49/64
= 0.765625
≈ 0.7656
Therefore, the probability of the dart hitting the area formed by bigger square and smaller square is equal to 0.7656.
