Evaluate 5-t\3 when t=12

False. Exponential smoothing with α = 0.2 and a moving average with n = 5 do not put the same weight on the actual value for the current period. Exponential smoothing and moving averages are two different forecasting techniques that use distinct weighting schemes.

Exponential smoothing uses a smoothing constant (α) to assign weights to past observations. With an α of 0.2, the weight of the current period's actual value is 20%, while the remaining 80% is distributed exponentially among previous values. As a result, the influence of older data decreases as we go further back in time.On the other hand, a moving average with n = 5 calculates the forecast by averaging the previous 5 periods' actual values. In this case, each of these 5 values receives an equal weight of 1/5 or 20%. Unlike exponential smoothing, the moving average method does not use a smoothing constant and does not exponentially decrease the weight of older data points.In summary, while both methods involve weighting schemes, exponential smoothing with α = 0.2 and a moving average with n = 5 do not put the same weight on the actual value for the current period.

Answer:

0.29 or 29 percent I put it on god

Step-by-step explanation:

The percentage of people attending supported the home team is 29%.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, 2400 people attended a basketball game. 696 of the people attending supported the home team, while 1704 supported the visiting team.

From the general formula of percentage:

percentage = value/ total value * 100

Since, Out  of 2400 only 696 supported the home team

thus,

Percentage = 696/2400*100

Percentage = 29%

Therefore, 29% percentage of people attending supported the home team.

The value of the car in 2000 is expected to be $3800, given a starting value of $7700 in 1990 and a decrease of $390 per year for 10 years.

To find the value of the car in each subsequent year, we can subtract $390 from the previous year's value. Let's calculate the value of the car for each year from 1990 to 2000.

Year 1990: $7700

Year 1991: $7700 - $390 = $7310

Year 1992: $7310 - $390 = $6920

Year 1993: $6920 - $390 = $6530

Year 1994: $6530 - $390 = $6140

Year 1995: $6140 - $390 = $5750

Year 1996: $5750 - $390 = $5360

Year 1997: $5360 - $390 = $4970

Year 1998: $4970 - $390 = $4580

Year 1999: $4580 - $390 = $4190

Year 2000: $4190 - $390 = $3800

Therefore, the value of the car is expected to be $3800 in the year 2000.

a. The graph of y = f(2x) is shown in the image below.

b. The graph of y = ½g(x) is shown in the image below.

In Mathematics, the vertex form of the equation for an absolute value function can be modeled by the following:

y = a|x - h| +k.

Where:

Part a.

By critically observing the graph of the parent absolute value function, we can reasonably and logically deduce that f(x) = -|2x| was horizontally stretched by a factor of 2 in order to produce the transformed absolute value function as follows;

f(x) = -|2x|

y = f(2x)

y = -|4x|

Part b.

By vertically shrinking the parent absolute value function by a factor of 1/2 in order to produce the transformed absolute value function, we have:

g(x) = -|2x|

y = ½g(x)

y = -½|2x|

19/9 ÷ 2/3 - 25/4 x 2/5

dividing fractions you can multiply and use reciprocal of the fraction (means you switch the top and bottom numbers)

19/9 x 3/2 - 25/4 x 2/5

you can reduce the top and bottom numbers to make them smaller by dividing. find a common number to divide them by, you can cross out the numbers and just put the new equation below

19/3 x 1/2 - 5/4 x 2/1

multiply across the fractions first PEMDAS, then subtract

19/6 - 10/4 (multiply by 2 and 3 respectively to get both bottom numbers the same, multiply by the same number on top)

57/12 - 30/12 = 27/12

1/5 x 1/3 + 2/5 x 2/3

1/15 + 4/15 = 5/15 or 1/3

The difference quotient for the given function is 9 -2/h.

The difference quotient for the given function can be calculated as:

[f(x+h) - f(x)]/h

= [(3(x+h)² - 2(x+h) + 5) - (3x² - 2x + 5)]/h

= (3x² + 6xh + 3h² - 2x - 2h + 5 - 3x² + 2x - 5)/h

= (6xh + 3h² - 2h)/h

= (6x + 3h -2)/h

Simplifying the expression further, we get:

(6x + 3h -2)/h = 6 + 3h/h -2/h

= 6 + 3 -2/h

= 9-2/h

The solution to the given initial value problem is y = (t^3/3) + 7t - (4/9), t > 0.

To solve this initial value problem, we can use the method of integrating factors. First, let's rewrite the equation in standard form: y' + (4/t)y = (t^2/t + 5)/t.

The integrating factor is given by the exponential of the integral of (4/t) dt, which simplifies to e^(4ln|t|) = t^4.

Multiplying both sides of the equation by the integrating factor, we have t^4y' + 4t^3y = t^3(t + 5).

Now, we can rewrite the left side of the equation as the derivative of the product of t^4 and y using the product rule: (t^4y)' = t^3(t + 5).

Integrating both sides of the equation, we get t^4y = (t^4/4)(t + 5) + C, where C is the constant of integration.

Simplifying the right side, we have t^4y = (t^5/4) + (5t^4/4) + C.

Dividing both sides of the equation by t^4, we obtain y = (t^3/4) + (5t/4) + (C/t^4).

Next, we can use the initial condition y(1) = 7 to find the value of C. Plugging in t = 1 and y = 7 into the equation, we have 7 = (1^3/4) + (5/4) + C.

Simplifying, we find C = 7 - (1/4) - (5/4) = (27/4).

Finally, substituting the value of C back into the equation, we have y = (t^3/4) + (5t/4) + ((27/4)/t^4).

Therefore, the solution to the initial value problem is y = (t^3/3) + 7t - (4/9), t > 0.

The solution to the initial value problem is y = (1/4)t^2 - (1/8)t + (21/16) + 0.3658.

To solve the given initial value problem, let's consider it as a linear first-order ordinary differential equation. The equation can be rewritten in standard form as:

ty' + 4y = t^2 + t + 5

To solve this equation, we'll use an integrating factor, which is defined as the exponential of the integral of the coefficient of y. In this case, the coefficient of y is 4, so the integrating factor is e^(∫4 dt) = e^(4t).

Multiplying both sides of the equation by the integrating factor, we have:

\(e^(4t)ty' + 4e^(4t)y = e^(4t)(t^2 + t + 5)\)

Applying the product rule on the left side of the equation, we can rewrite it as:

\((d/dt)(e^(4t)y) = e^(4t)(t^2 + t + 5)\)

Integrating both sides with respect to t, we get:

\(e^(4t)y = ∫e^(4t)(t^2 + t + 5) dt\)

Simplifying the integral on the right side:

\(e^(4t)y = ∫(t^2e^(4t) + te^(4t) + 5e^(4t)) dt\)

To evaluate the integral, we use integration by parts. Let \(u = t^2\) and \(dv = e^(4t) dt:\)

\(du = 2t dtv = (1/4)e^(4t)\)

Substituting these values into the integration by parts formula:

\(∫(t^2e^(4t)) dt = t^2(1/4)e^(4t) - ∫(2t)(1/4)e^(4t) dt= (1/4)t^2e^(4t) - (1/2)∫te^(4t) dt\)

We repeat the process for the remaining integrals:

\(∫te^(4t) dt = (1/4)te^(4t) - (1/4)∫e^(4t) dt= (1/4)te^(4t) - (1/16)e^(4t)\)

\(∫e^(4t) dt = (1/4)e^(4t)\)

Plugging these results back into the equation, we have:

\(e^(4t)y = (1/4)t^2e^(4t) - (1/2)((1/4)te^(4t) - (1/16)e^(4t)) + 5∫e^(4t) dt\)

Simplifying further:

\(e^(4t)y = (1/4)t^2e^(4t) - (1/8)te^(4t) + (1/16)e^(4t) + (5/4)e^(4t) + C\)

Now, we divide both sides by e^(4t) and simplify:

\(y = (1/4)t^2 - (1/8)t + (21/16) + (5/4)e^(-4t)\)

To find the particular solution that satisfies the initial condition y(1) = 7, we substitute t = 1 and y = 7 into the equation:

\(7 = (1/4)(1^2) - (1/8)(1) + (21/16) + (5/4)e^(-4)\)

Simplifying the equation:

\(7 = 1/4 - 1/8 + 21/16 + 5/4e^(-4)\)

Multiplying through by 16 to clear the fractions:

\(112 = 4 - 2 + 21 + 20e^(-4)\)

Simplifying further:

\(89 = 20e^(-4)\)

Dividing by 20:

\(e^(-4) = 89/20\)

Taking the natural logarithm of both sides to isolate the exponent:

\(-4 = ln(89/20)\)

Solving for the exponent:

\(e^(-4) ≈ 0.1463\)

Therefore, the particular solution to the initial value problem is:

\(y = (1/4)t^2 - (1/8)t + (21/16) + (5/4)(0.1463)= (1/4)t^2 - (1/8)t + (21/16) + 0.3658\)

In summary, the solution to the initial value problem is \(y = (1/4)t^2 - (1/8)t + (21/16) + 0.3658.\)
