25 Points Use Bisection Method to locate the root of f(x) = x/3 + In(x) - 1 on a closed interval [1,2]. Use 17 iterations to extract the root.
The Bisection Method is a numerical method used to find the roots of a function within a given interval. It works by repeatedly dividing the interval in half and checking which half contains the root until the desired level of accuracy is achieved. In this case, we are using 17 iterations to extract the root of the function f(x) = x/3 + In(x) - 1 on the closed interval [1,2].
To locate the root of f(x) = x/3 + In(x) - 1 on a closed interval [1,2] using the Bisection Method with 17 iterations, we will follow the steps below:
1. Define the function f(x) = x/3 + In(x) - 1
2. Set the initial values for the interval: a = 1 and b = 2
3. Start the iteration process by finding the midpoint of the interval: c = (a+b)/2
4. Evaluate the function at the midpoint: f(c) = f((a+b)/2)
5. Determine if the root lies in the left or right half of the interval by checking the sign of f(c)
6. If f(c) is positive, then the root lies in the left half of the interval, so we set b = c and repeat the process from step 3.
7. If f(c) is negative, then the root lies in the right half of the interval, so we set a = c and repeat the process from step 3.
8. Continue the iteration process until we have completed 17 iterations.
After 17 iterations, we will have narrowed down the interval to a very small range and the midpoint of this interval will be an approximation of the root of the function.

Use the image to determine the direction and angle of rotation.
90° clockwise rotation
270° clockwise rotation
90° counterclockwise rotation
180° counterclockwise rotation
After comparing the image and the figure, we found that the direction and angle of rotation are 180° counterclockwise rotation.
What is meant by the rotation of figures?A transformation known as a rotation involves turning the figure either clockwise or counterclockwise. The centre of rotation is the fixed location where the rotation occurs. The term "angle of rotation" refers to the amount of rotation. A figure can be rotated 90 degrees, or a quarter turn, in either a clockwise or counterclockwise direction. You have rotated the figure 180 degrees when you have spun it exactly halfway. The figurine may be rotated 360° by turning it all the way around. A counterclockwise turn has a positive magnitude because a clockwise rotation indicates a negative magnitude. Rotational symmetry exists in every regular polygon. When an object is rotated around its centre, it retains its original appearance. The object is then referred regarded as having rotational symmetry.
Let's write the coordinates of the original figure,
A = (1, -5)
B = (6, -2)
C = (6, -5)
D = (1, -8)
Now, if we rotate it 90 degrees counterclockwise, the coordinates are:
A' = ( 5, 1)
B' = (2, 6)
C' = (5, 6)
D' = (8, 1)
Now if we rotate it again 90 degrees counterclockwise, the coordinates are:
A'' = ( -1, 5)
B'' = (-6, 2)
C'' = (-6, 5)
D'' = (-1, 8)
Now from the figure, let's write the coordinates.
A' = ( -1, 5)
B' = (-6, 2)
C' = (-6, 5)
D' = (-1, 8)
This is the same as the coordinates of the second 90 degrees counterclockwise rotation.
Since we did two 90 degrees rotations, we can say we did a total of 180° counterclockwise rotation.
Therefore after comparing the image and the figure, we found that the direction and angle of rotation are 180° counterclockwise rotation.

On an analog clock, the hour hand rotates 30 degrees as the second hand rotates 21,600 degrees. Which equation correctly relates the variables defined below?
h: angular motion of the hour hand, in degrees
s: angular motion of the second hand, in degrees
Step-by-step explanation:
the ratio is 30/21600 = 3/2160 = 1/720
that means for every degree the hour hand moves, the second hand does 2 full rotations (2×360°).
h = s×30/21600 = s/720
FYI :
as there are 12 hours on a clock, every hour means 360/12 = 30° rotation for the hour hand.
so, for each hour the second hand moves 21600°.
that means 21600/360 = 60 full rotations.
that means one rotation of the second hand is 1 minute.
so, the second hand is truly a second hand (counting the seconds).
60 seconds in a minute (a full rotation by the second hand), that means each second corresponds to 360/60 = 6° rotation of the second hand.

We can conclude that the students did not have any time left to work on homework.
The duration of Mr. K's math class is 1 and 1/4 hours, or 5/4 hours.
We need to determine how much time is left for the kids to do their assignment after working on problems on the board for 55 minutes and 11/12 hours. To achieve this, we must take the time spent solving issues out of the overall class time:
Total class time = 5/4 hours
Time spent on working problems = 55 minutes + 11/12 hours
= (55/60) hours + (11/12) hours
= (11/12 + 55/60) hours
= (11/12 + 11/12) hours
= (22/12) hours
= (11/6) hours
Overall class time minus the amount of time spent solving problems equals the amount of time remaining for homework.
= 5/4 hours - 11/6 hours
= (15/12) hours - (22/12) hours
= (-7/12) hours
We can infer that the kids ran out of time to finish their homework because the response is illogical because we cannot have negative time.

We can factor out (w-2) to get: (w-2)(w2 - 4w - 54) = 0
Now we can factor the second part of the equation, by splitting the middle term (4w) to get: (w-2)(w-9)(w+6) = 0
Now we have three equations, which we can solve separately:
w - 2 = 0 → w = 2
w - 9 = 0 → w = 9
w + 6 = 0 → w = -6

2x3+3x2-12x+5 criterio de la primera derivada
Answer:
To apply the first derivative test to the function f(x) = 2x^3 + 3x^2 - 12x + 5, we need to find its derivative:
f'(x) = 6x^2 + 6x - 12
Then, we need to find the critical points by solving for f'(x) = 0:
6x^2 + 6x - 12 = 0
Dividing both sides by 6, we get:
x^2 + x - 2 = 0
Factoring the left side, we get:
(x + 2)(x - 1) = 0
So the critical points are x = -2 and x = 1.
To determine the intervals where f(x) is increasing and decreasing, we need to evaluate f'(x) on each side of the critical points. We can use a sign chart to do this:
x | -2 | 1 |
------|-----|----|
f'(x) | -12 | 0 |
Since f'(x) is negative to the left of x = -2 and positive to the right of x = -2, the function is decreasing to the left of x = -2 and increasing to the right of x = -2. Since f'(x) changes sign at x = 1, there is a local minimum at x = 1.
Therefore, using the first derivative test, we can conclude that the function has a local minimum at x = 1.

At a carnival game, it cost Taylor $6 to toss 63 rings. Fill out a table of equivalent ratios and plot the points on the coordinate axes provided.
Graph is the collection of all points whose coordinates satisfy a given relation (such as a function).
What is coordinates?Coordinates of a point in a 2D plane, also known as cartesian coordinates, are two numbers or sometimes a combination of a letter and a number that tell us the exact location of a specific point on a grid. Here, the grid is known as a coordinate plane.
Let tosses be x and and dollars be y
Then we have, (x, y) as (63, 6)
So if in 6 dollars you get 63 tosses then 1 dollar you get = 63/6 = 10.5 tosses.
Then in 2 dollars we have = 10.5 × 2 = 21 tosses
As 21 tosses = 2 dollars
Then 42 tosses = 2 × 2 = 4 dollars
Thus, we have the table:
[tex]\boxed{\begin{array}{cc}\underline{\text{Tosses}}&\underline{\text{dollars}}&\\ \boxed{10.5}&2&\\42&\boxed4&\\63&6&\end{array}}[/tex]
To graph the given points, just correspond x as tosses and y as dollars.

A watch was bought for 2,700 including 8% VAT. Find its price before the VAT was added.
Answer:
Let's assume that the price before adding the VAT is x.
We know that the VAT rate is 8%, which means that the VAT amount is 8% of x, or 0.08x.
The total price including VAT is the sum of the price before VAT and the VAT amount, so we can write:
Total price = price before VAT + VAT amount
or
2,700 = x + 0.08x
Simplifying this equation, we can combine like terms on the right-hand side to get:
2,700 = 1.08x
To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 1.08:
x = 2,700 / 1.08
x = 2,500
Therefore, the price before VAT was added is 2,500.

The missing value in this equation is 4, or (4)/(1) in fraction form.
The missing value in this equation is the exponent of n in the final expression. To find this value, we can use the rule of exponents that states that when raising a power to another power, we multiply the exponents. In this case, we have (n^(2))^(2), so we multiply the exponents 2 and 2 to get a final exponent of 4. Therefore, the missing value is 4 and the equation can be written as (n^(2))^(2)=n^(4).
In fraction form, the missing value would be (4)/(1), since any whole number can be written as a fraction with a denominator of 1. So, the equation can also be written as (n^(2))^(2)=n^((4)/(1)).
Overall, the missing value in this equation is 4, or (4)/(1) in fraction form.

Assume that y = f(x) is a rational function satisfying the following constraints: i. There is a x-intercept at x = 0, and the local approximation here is given by y = ii. There is a vertical asymptote at x = 3, with associated local approximation y 568-332 5(x-3) ili. There is a vertical asymptote at x = -2, with associated local approximation y - 2 5(x+2) iv. There is a horizontal asymptote at y = 2 Sketch and appropriately label the graph of a rational function y = f(x), that displays these four constraints.
The graph of the rational function y = f(x) is represented by the blue line on the graph above. The x-intercept is the point at which the function crosses the x-axis and is labeled (0, 0).
The vertical asymptote at x = 3 is the red line. The local approximation for the vertical asymptote at x = 3 is represented by the black line and is given by y = 568 - 332(x - 3). Similarly, the vertical asymptote at x = -2 is the purple line and the associated local approximation is given by y = -2(x + 2). Finally, the horizontal asymptote at y = 2 is the orange line.
To illustrate the graph, assume the function f(x) is the following: f(x) = (x + 2)(x - 3) / (x + 5). This function is a rational function, as it is the ratio of two polynomials, and it has the given constraints.
To graph the rational function, we begin by finding the x-intercept, which is (0, 0). Then, we look at the vertical asymptote. At x = 3, the local approximation is given by y = 568 - 332(x - 3). We solve the equation y = 568 - 332(x - 3) for x, and get x = 3, thus we mark this point on the graph as the vertical asymptote. We do the same for the vertical asymptote at x = -2 and mark this point on the graph. Finally, we draw the line for the horizontal asymptote at y = 2. This gives us the complete graph of the rational function y = f(x).
In conclusion, the graph of the rational function y = f(x) that displays the four constraints can be sketched and labeled as shown in the figure above.
