Step-by-step explanation:

Each card has two parts. A top part and bottom part. On the top parts of all the cards, there's a simple pattern of adding 2 to the previous number each time. On the bottoms of the cards, you have to add 3 to a number to get to the next number in line. Therefore, take the 4th card (8 on top 14 on bottom) and add a 2 to the top number and a 3 to the bottom number to get the next card in the pattern.

8   +   2   =   10  

---                 ---      

14  +  3   =    17

So card 5 is

Numerical values that appear in the mathematical relationships of a model and are considered known and remain constant over all trials of a simulation are parameters.

Numerical values that appear in the mathematical relationships of a model and are considered known and remain constant over all trials of a simulation are not referred to as events.

In the context of simulations, these constant numerical values are typically known as parameters.

Parameters are fixed values that define the characteristics of a system or model being simulated.

They represent the fixed inputs or conditions that remain constant throughout the simulation.

These values are determined based on prior knowledge, experimental data, or theoretical assumptions.

For example, in a simulation model of a manufacturing process, parameters may include the production rate, the machine capacity, the setup time, or the defect rate.

These values are known and constant throughout the simulation runs.

It is important to distinguish parameters from variables in simulations. While parameters remain constant, variables are the factors or quantities that can change during the simulation and are often the focus of analysis or study.

By incorporating known and constant parameter values into a simulation model, researchers can analyze the behavior and performance of the system under different conditions, explore various scenarios, and make predictions or decisions based on the simulation outcomes.

Answer:

Height above the bottom gorge is 113 feet

Step-by-step explanation:

The width of the gorge = 40 feet

The height of the higher cliff = 158 feet

The height of the lower cliff = 98 feet

The length of the bridge = √((158-98)² + 40²) = 72.11 feet

The slope of the bridge = (158-98)/40 = 1.5

The length of 1/4 of the bridge from the lower cliff =72.11 - 3/4×72.11 = 18.03 feet

The angle of inclination of the bridge = tan⁻¹(1.5) = 56.31°

The height above the bottom at 3/4 from the higher cliff = The height above the bottom at 1/4 from the lower cliff = 98+ 18.03×sin(56.31 ) = 113 feet

Which can also be found directly from the heights of the two cliffs knowing that 3/4 from the higher cliff = 1/4 from the lower cliff giving;

Height above the bottom gorge = 98 + 1/4×(158 - 98) = 113 feet.

Option C Ill only is the right option

Let's analyze each option one by one:

I. arccos(sins):

The range of the arcsine function is [-π/2, π/2], and the range of the cosine function is [0, π].

Since the arcsine of any value is always between -π/2 and π/2, it is not possible to have a value outside that range. Therefore, arccos(sins) is not a valid expression.

II. ectan(cot(-7)):

The tangent function has a period of π, which means tan(x) = tan(x + π) for any value of x.

Therefore, tan(-7) is the same as tan(-7 + π) = tan(-7 + 3.14...) = tan(-3.14...), which is defined and equal to 0.

Since the cotangent is the reciprocal of the tangent, cot(-7) = 1/tan(-7) = 1/0, which is undefined. Thus, ectan(cot(-7)) is not a valid expression.

III. arcsin(csc):

The cosecant function (csc) is the reciprocal of the sine function, so csc(x) = 1/sin(x).

The arcsine function (arcsin) is the inverse of the sine function, so arcsin(sin(x)) = x for any x within the range of the arcsin function.

Therefore, arcsin(csc) simplifies to arcsin(1/sin), and since these functions are inverses of each other, arcsin(1/sin) = x.

The value of x depends on the specific value of sin, which is not provided.

Therefore, arcsin(csc) is a valid expression, but we cannot determine a specific value without knowing the value of sin.

Therefore, the correct answer is C. III only.

Answer:

hold on its its.............oh yeah 21

Answer:

  b

Step-by-step explanation:

The simplified expression is 1.5 / 0.134, which can be further simplified to approximately 11.19.

To simplify the expression (cos(-60) - tan135) / (tan315 - cos660), we can break it down into two steps.

Step 1: Calculate the values inside the expression.

cos(-60) is equal to cos(60), which is 0.5.

tan135 is equal to -1, as tangent is negative in the second quadrant.

tan315 is equal to 1, as tangent is positive in the fourth quadrant.

cos660 is equal to cos(660-360) which is cos(300), and cos(300) is equal to 0.866.

Step 2: Substitute the calculated values into the expression.

The numerator becomes (0.5 - (-1)) = (0.5 + 1) = 1.5.

The denominator becomes (1 - 0.866) = 0.134.

Therefore, the simplified expression is 1.5 / 0.134, which can be further simplified to approximately 11.19.

Answer:

white sold = 16

yellow sold = 12

Step-by-step explanation:

w = # of white sold

y = # of yellow sold

w + y = 28   solve this for w

w = 28 - y

9.95w + 13.5y = 321.20     substitute w = 28-y into this expression and solve for y

9.95(28-y) + 13.5y = 321.20

278.60 - 9.95y + 13.50y = 321.20

278.60 + 3.55y = 321.20

3.55y = 321.20 - 278.60 = 42.60

y = 42.60/3.55 = 12   substitute this into w = 28 - y and solve for w

w = 28 - 12 = 16

Answer:

The slope is 3, and the y-intercept is -1/2

Two terms, \(-4z^2\) and \(-5z^2,\) both involving the variable z of degree 2, form an equation. We combine these similar concepts to make the expression more concise.

Adding or deleting terms raised to the same power(s) with the same variable(s) is known as combining like terms. Since both terms contain z2 in this example, we can add them.

We can combine like terms to simplify the expression\((-4z^2 - 11u) - 5z^2\).

It is possible to rewrite the expression\((-4z^2 - 11u) - 5z^2\) as:

\(-4z^2 - 5z^2 - 11u\)

The terms with the same variable (z) and constant term (-11u) can now be combined as follows:

\((-4 - 5)z^2 - 11u\)

Even more simply, we have:

\(-9z^2 - 11u\)

For any price of h and k = -12, the system x + 3y = h and -4x + ky = -9 will haven't any answer.

To determine the values of h and okay for which the device of equations has no answer, we want to locate the situations underneath which the equations are inconsistent or parallel.

The given system of equations is:

Equation 1: x + 3y = h

Equation 2: -4x + ky = -9

For the gadget to haven't any answer, the lines represented with the aid of these equations should be parallel and in no way intersect. In different phrases, the slopes of the traces need to be equal, but the y-intercepts should be specific.

Let's first discover the slopes of the traces. The slope-intercept form of Equation 1 is y = (-1/3)x + (h/3), wherein the slope is -1/3. The slope-intercept shape of Equation 2 is y = (4/k)x - (9/k), wherein the slope is 4/k.

For the strains to be parallel, the slopes should be equal. Therefore, we have the condition: -1/3 = 4/k.

To locate the values of h and okay for which the gadget has no answer, we need to locate the values of h that satisfy the situation -1/3 = 4/k.

Solving this equation for ok, we've got:

-1/3 = 4/k

-1 = 12/k

k = -12

Substituting k = -12 returned into the equation -1/3 = 4/k, we've:

-1/3 = 4/(-12)

-1/3 = -1/3

Since the equation holds real for any value of h, there aren't any restrictions at the price of h.

The system of equations has no solution when k is equal to 12. The value of h can be any real number.

To determine the values of h and f for which the system has no solution, we need to analyze the coefficients of the variables and the constants in the equations.

The given system of equations is:

x + 3y = h

-4x + ky = -9

We can rewrite the second equation as:

-4x + ky = -9

Dividing both sides of the equation by -4, we get:

x - (k/4)y = 9/4

Comparing the coefficients of x and y in the two equations, we can see that the slopes of the lines represented by the equations are different when k is not equal to 12.

Therefore, for the system to have no solution, k must be equal to 12.

As for the value of h, it can be any real number since it does not affect the slopes of the lines.

The required perimeter is 60 cm,

Hence option D is correct.

In the given figure

DCAB and HGFE are similar

CD = 5 cm

CB = 10 cm

Since the given area of rectangle HGFE = 200 cm²

Therefore,

GH x FG = 200 cm² ...(i)

From similarity

DC/CB = GH / FG

⇒ 5/10 = GH / FG

⇒   GH = (5/10)FG

Now put it into (i)

⇒ (5/10)FG x FG = 200 cm²

⇒        (5/10)FG² = 200 cm²

⇒                 FG² = 400 cm²

⇒                  FG = 20 cm

Now plug value of FG into (i)

⇒ GH = 10 cm

Now perimeter of rectangle = 2( length + width)

                                               = 2(GH + FG)

                                               = 2(10+20)

The Hermite curve with four control points P0(0,0), P1(1,1), P2(2,-1), and P3(3,0) has tangent vectors P0'(1,1) and P3'(1,1) at the endpoints. To determine the intermediate points on the curve at t = 1/3 and t = 2/3, we can use the Hermite interpolation formula.

The Hermite interpolation formula allows us to construct a curve based on given control points and tangent vectors. In this case, we have four control points P0, P1, P2, and P3, and tangent vectors P0' and P3'.

To find the intermediate point at t = 1/3, we use the Hermite interpolation formula:

P(t) = \((2t^3 - 3t^2 + 1)P0 + (-2t^3 + 3t^2)P3 + (t^3 - 2t^2 + t)P0' + (t^3 - t^2)P3'\)

Substituting the given values:

\(P(1/3) = (2(1/3)^3 - 3(1/3)^2 + 1)(0,0) + (-2(1/3)^3 + 3(1/3)^2)(3,0) + ((1/3)^3 - 2(1/3)^2 + (1/3))(1,1) + ((1/3)^3 - (1/3)^2)(1,1)\)

Simplifying the equation, we can find the coordinates of the intermediate point at t = 1/3.

Similarly, for t = 2/3, we use the same formula:

\(P(2/3) = (2(2/3)^3 - 3(2/3)^2 + 1)(0,0) + (-2(2/3)^3 + 3(2/3)^2)(3,0) + ((2/3)^3 - 2(2/3)^2 + (2/3))(1,1) + ((2/3)^3 - (2/3)^2)(1,1)\)

Calculating the equation yields the coordinates of the intermediate point at t = 2/3.

In this way, we can use the Hermite interpolation formula to determine the intermediate points on the Hermite curve at t = 1/3 and t = 2/3 based on the given control points and tangent vectors.
