The graph is not symmetric about the y axis, which tells us that the function is not even.

All odd functions pass through the origin, so this function is not odd either.

The plane will reach an altitude of 21,000 feet approximately 29.2 minutes after lift off. Rounded to the nearest whole minute, the plane will be at an altitude of 21,000 feet 37 minutes after lift off.

To determine the number of minutes after lift off when the plane reaches an altitude of 21,000 feet, we need to solve the equation a = 21,000, where "a" represents the altitude in feet. By substituting the altitude value into the equation and solving for the variable, we can find the number of minutes.

The given equation represents the altitude "a" of the plane in feet, given by a = 3480 + 600t, where "t" represents the time in minutes after lift off. We need to find the number of minutes when the plane is at an altitude of 21,000 feet.

By substituting a = 21,000 into the equation, we have:

21,000 = 3480 + 600t

To isolate "t," we subtract 3480 from both sides:

21,000 - 3480 = 600t

Simplifying, we get:

17,520 = 600t

Dividing both sides by 600, we find:

t = 29.2

2.5 is the equal epression of 5/2

By analytical methods and algebraic handling and on the basis that x is increased by 25 %, we conclude that the variable x² is increased by 18.75 %.

In this case we have a linear variable x, whose increase is described by the following expression:

y = x · (1 + r/100)     (1)

Where r is the increase rate.

If we square (1), then we find that:

y² = x² · (1 + r/100)² = (1 + r'/100)     (2)

Where r' is the equivalent increase rate.

(1 + r/50 + r²/10000) = (1 + r'/100)

r'/100 = r/50 + r²/10000

r' = r/2 + r²/100

If we know that r = 25, then the equivalent increase rate is:

r' = 25/2 + 25²/100

r' = 18.75

By analytical methods and algebraic handling and on the basis that x is increased by 25 %, we conclude that the variable x² is increased by 18.75 %.

Step-by-step explanation:

A dilation is a transformation which generates an image that is the same shape as the original object but in a different size.

The image can be obtained by multiplying the measure of the original object by a scale factor.

If the scale factor > 1, the image is stretched

If the scale factor < 1, the image is reduced

If the scale factor = 1, the image and object will be congruent

For example, if we multiply the measure of the coordinates of the vertex A(2, 2) of a triangle by a scale factor of 2, the image A' is stretched as the scale factor > 1.

Dilation with scale factor 2, multiply by 2.

A(2, 2) → (2(2), 2(2)) = A'(4, 4)

So, the image point A'(4, 4) is enlarged.

Dilation with scale factor ½, multiply by ½.

A(2, 2) → (2(1/2), 2(1/2)) = A'(1, 1)

So, the image point A'(1, 1) is reduced.

Now,

4410×8= 35280.

The area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Area of regular polygon = 1/2 × apothem × perimeter

perimeter = (s)side length of octagon × (n)number of side.

apothem = s/[2tan(180/n)].

11 = s/[2tan(180/12)]

s = 11 × 2tan15

s = 5.8949

perimeter = 5.8949 × 12 = 70.7388

Area of dodecagon = 1/2 × 11 × 70.7388

Area of dodecagon = 389.0634 in²

Area of pentagon = 1/2 × 5.23 × 7.6

Area of pentagon = 19.874 in²

Therefore, the area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Answer:

\(\textsf{Step 1:}\quad m = \dfrac{1}{2}\)

\(\textsf{Step 2:}\quad m = \dfrac{1}{2}\)

\(\textsf{Step 3:}\quad y-4=\dfrac{1}{2}(x-2)\)

Step-by-step explanation:

Given linear equation:

\(y=\dfrac{1}{2}x+4\)

The given equation is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

\(\begin{array}{l}y=\boxed{\dfrac{1}{2}}\;x+\;\boxed{4}\\\;\;\;\;\;\;\;\;\uparrow\;\;\;\;\;\;\;\;\;\;\;\:\uparrow\\\sf \;\;\;\;\;slope\;\;\;\;\;\textsf{$y$-intercept}\end{array}\)

Therefore, the slope of the given line is:

\(m = \dfrac{1}{2}\)

We are told that the new line is parallel to the given line.

Since parallel lines have the same slope, the slope of the new line is the same as the slope of the given line:

\(m = \dfrac{1}{2}\)

We are told that the new line passes through the point (2, 4).

Therefore, we can plug in the found slope, m = 1/2, and the given point (2, 4), into the point-slope form:

\(y-y_1=m(x-x_1)\)

\(y-4=\dfrac{1}{2}(x-2)\)

There are 48 ways to choose two different cards from a standard 52-card deck such that (a) The first card is an Ace and the second card is not a Queen.

Explanation: We are given that a standard deck of 52 cards. (a) The first card is an Ace and (b) the second card is not a Queen. In a standard deck of 52 cards, there are four aces. If the first card drawn is an ace, then there are 51 cards left in the deck and 12 cards that are queens. Hence, there are 51 − 12 = 39 cards that are not queens. So, we can say that, There are 4 aces × 39 cards that are not queens = 156 ways to choose two different cards from a standard 52-card deck such that the first card is an Ace and the second card is not a Queen.

However, we have to remove the case where both cards are aces and the second card is a queen. So, we subtract 1 from the previous answer to get, 156 − 1 = 155 ways to choose two different cards from a standard 52-card deck such that (a) The first card is an Ace and the second card is not a Queen.

The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.

A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.

B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.

\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.

That leaves \(27-14=13\) matches. These represent the matches team lost.

Finally, the answers are below.

\(A)29\)
\(B)13\)

Answer:

  a) 29 points

  b) 13 losses

Step-by-step explanation:

You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.

The number of points the team has is ...

  P = 3W +D

  P = 3(8) +(5) = 29

The team has 29 points.

You want the number of losses the team has if it has 54 points and 12 draws after 39 games.

The number of wins is given by ...

  P = 3W +D

  54 = 3W +12

  42 = 3W

  14 = W

Then the number of losses is ...

  W +D +L = 39

  14 +12 +L = 39 . . . substitute the known values

  L = 13 . . . . . . . . . . subtract 26 from both sides

The team lost 13 games.

Additional comment

In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

Step-by-step explanation:

In problem 1, an initial value problem is given with a first-order differential equation. The exact solution, y(t), is obtained, and Euler's method is used with different step sizes to obtain numerical solutions, u(t), at t=3.In problem 2, the second-order Runge-Kutta method (improved Euler's method) is applied to the same initial value problem. The numerical solution, v(t), is obtained at t=3 with h=0.1.

In problem 1, the initial value problem is solved analytically to obtain the exact solution, y(t). Euler's method is then applied with different step sizes (h) to approximate the solution numerically at t=3. The numerical solution, u(t), is plotted alongside the exact solution, y(t), to visualize their comparison. The error, e1, is calculated as the maximum absolute difference between u(t) and y(t) over the interval [0, 3]. By varying the step size and computing e1, the effect of the step size on the accuracy of the numerical solution can be observed.

In problem 2, the second-order Runge-Kutta method is employed to approximate the solution numerically. The numerical solution, v(t), is computed at t=3 with h=0.1 and compared to the exact solution, y(t), through a plot. The error, e2, is calculated as the maximum absolute difference between v(t) and y(t) over the interval [0, 3]. By computing e2 for different step sizes and comparing it to e1 from problem 1, the difference between the two numerical methods can be observed in terms of accuracy and convergence.

The saddle points of the function h(x, y) are the points where the function has a critical point but not a relative minimum or maximum value. Given function is h(x, y) = x³ - 3x + 3xy² .

To find the relative minima and maxima of the given function h(x, y), we need to find the partial derivatives of h(x, y) with respect to x and y. Then, we have to solve the system of equations. To find the partial derivative of h(x, y) with respect to x, we have to treat y as a constant. Therefore, Partial derivative of h(x, y) with respect to x, ∂h/∂x = 3x² - 3y To find the partial derivative of h(x, y) with respect to y, we have to treat x as a constant.

Hence, the point (1, 1) is a relative minimum point of the function h(x, y).The saddle point of the function h(x, y) can be found by checking the value of the function h(x, y) at the critical point (0, 0) and comparing it with the value of the function at the nearby points. The value of the function h(x, y) at (0, 0) is h(0, 0) = 0. The value of the function at the nearby point (0, 1) is h(0, 1) = -3. Therefore, the point (0, 0) is a saddle point of the function h(x, y).Hence, the relative minima and maxima and saddle points of the function h defined by h(x, y) = x³ - 3x + 3xy² are as follows: Relative minimum: (1, 1)Saddle point: (0, 0)

Water in pool = 10L/hour × 2 hours = 20L.

b) The pool will be 80L when the equation is satisfied: 80L = 10L/hour × Time.

Solving for Time, we find Time = 8 hours.

c) Part b) is linear.

a) To calculate the amount of water in the pool after 2 hours, we can use the equation:

Water in pool = Water filling rate × Time

Since the pool gets filled up with 10L of water per hour, we can substitute the values:

Water in pool = 10 L/hour × 2 hours = 20L

Therefore, after 2 hours, there will be 20 liters of water in the pool.

b) To determine the number of hours it takes for the pool to reach 80 liters, we can set up the equation:

Water in pool = Water filling rate × Time

We want the water in the pool to be 80 liters, so the equation becomes:

80L = 10 L/hour × Time

Dividing both sides by 10 L/hour, we get:

Time = 80L / 10 L/hour = 8 hours

Therefore, it will take 8 hours for the pool to contain 80 liters of water.

c) Part b) is linear.

The equation Water in pool = Water filling rate × Time represents a linear relationship because the amount of water in the pool increases linearly with respect to time.

Each hour, the pool fills up with a constant rate of 10 liters, leading to a proportional increase in the total volume of water in the pool.
