The Taylor polynomials T2(x) and T3(x) centered at x=3 for f(x) = ln(x+1) are:
T2(x) = f(3) + f'(3)(x-3) + f''(3)[tex](x-3)^2[/tex]
T3(x) = T2(x) + f'''(3)[tex](x-3)^3[/tex]
To calculate these polynomials, we need to find the first three derivatives of f(x) = ln(x+1) and evaluate them at x=3.
First derivative:
f'(x) = 1/(x+1)
Second derivative:
f''(x) = [tex]-1/(x+1)^2[/tex]
Third derivative:
f'''(x) = [tex]2/(x+1)^3[/tex]
Now, let's evaluate these derivatives at x=3:
f(3) = ln(3+1) = ln(4)
f'(3) = 1/(3+1) = 1/4
f''(3) = [tex]-1/(3+1)^2[/tex]= -1/16
f'''(3) = [tex]2/(3+1)^3[/tex]= 2/64 = 1/32
Substituting these values into the Taylor polynomials:
T2(x) = ln(4) + (1/4)(x-3) - [tex](1/16)(x-3)^2[/tex]
T3(x) = ln(4) + (1/4)(x-3) - (1/16)(x-3)^2 +[tex](1/32)(x-3)^3[/tex]

In triangle below, angle p is a right angle. Suppose that m angle q =(3x+25) and m angle r = (4x+30).
(A) write an equation to find x. Make sure you use an “=“ sign in your answer.
(B) find the degree measure of each angle.
(A) To find x, we can use the fact that the measures of the angles in a triangle must add up to 180 degrees. So we can write an equation using that information and the measures of angles q and r:
m angle q + m angle r + 90 = 180
(3x+25) + (4x+30) + 90 = 180
so:
7x+45 = 90
7x = 45
x = 45/7 = 5
(B) To find the degree measure of each angle, we can substitute x = 5 back into the expressions for angles q and r.
m angle q = (3x+25) = (3*5+25) = 40 degrees
m angle r = (4x+30) = (4*5+30) = 50 degrees
Since the angle p is a right angle, it has a degree measure of 90 degrees.
So the angle measures are: angle q = 40 degrees, angle r = 50 degrees, angle p = 90 degrees.

What is the graph of a function?
The graph of a function is a visual representation of the relationship between the input values (x-coordinates) and the output values (y-coordinates) of the function. In other words, it is a visual representation of the function's rule.
The graph of a function can take many different forms, depending on the function's rule. Linear functions, for example, will produce a straight line on the graph.
-4y > -x + 12 is a linear inequality. To solve this inequality, we can start by isolating y:
y < x/4 - 3
This inequality is in slope-intercept form (y = mx + b), where the slope is m = -1/4 and the y-intercept is b = -3.
To graph the solution, you can pick a few x-values and substitute them into the inequality to find the corresponding y-values.
You can use x = -8, x = -4, x = 0, x = 4, x = 8 for example and find the y-values for each x, y < -8/4 -3 = -2, y < -4/4 -3 = -1, y < 0/4 -3 = -3, y < 4/4 -3 = -1 and y < 8/4 -3 = -1/2.
Then plot those points on a coordinate plane and draw the line that goes through them, and shade the half-plane that is above the line
Hence, the solution is the set of all points (x,y) that satisfy the inequality y < x/4 - 3.

What is Heron's formula for area of triangle Class 9?
Heron's formula is a formula used to calculate the area of a triangle when the lengths of its three sides are known.
It is named after Hero of Alexandria, a Greek mathematician and engineer who first derived this formula.
The formula states that the area of a triangle is equal to the square root of the product of the semi-perimeter (half the sum of the three sides) and the differences of the semi-perimeter and each side.
Mathematically, Heron's formula can be written as:
A = √(s(s-a)(s-b)(s-c)),
where A is the area of the triangle, s is the semi-perimeter and a, b, c are the length of the three sides of the triangle.
For example, if the lengths of the three sides of a triangle are 5 cm, 6 cm and 7 cm, then the semi-perimeter (s) is (5 + 6 + 7)/2 = 9 cm.
Using Heron's formula, the area of the triangle is:
A = √(9(9-5)(9-6)(9-7)) = √(9*4*3*2) = √432 = 6.48 cm2

b. Define the function (w) to repreent the length of the field a
The length available will be (300-W) feet, where W represents the breadth (width) of the rectangle.
Let L, A, and W represent the length, area, and width of the rectangular field respectively.
A quadrilateral with parallel sides equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.
The area a two-dimensional form occupies in a plane is known as its area. It has a square unit of measurement. As a result, the rectangle's area is the space enclosed by its exterior lines. It is the same as the length times the width calculation.
Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel.
Based on the data given we have,
2L + 2W = 60
=>2L=60-2W
=>L=(60-2W)/2
=>L=2(30-W)/2
∴ L=(30-W) feet
Thus, the length available will be (300-W) feet.
Therefore, Thus, the length available will be (300-W) feet.

What happens when a figure is dilated by a scale factor of less than 1?
When a figure is dilated by a scale factor of less than 1, it becomes smaller as the coordinates of each point on the figure will be multiplied by a value less than 1. This results in a reduction of the size of the figure while preserving its shape.
For example, if a figure is dilated by a scale factor of 0.5, the coordinates of each point on the figure will be multiplied by 0.5. This means that each point on the figure will be moved half as far from the origin as it was before the dilation.
The result of this is that the dilated figure will be smaller than the original figure and will have a scale factor of less than 1.
It's important to note that if the scale factor is less than 1, the dilation will reduce the size of the figure and if the scale factor is greater than 1, the dilation will increase the size of the figure.

The graph of a function can take many different forms, depending on the function's rule. Linear functions, for example, will produce a straight line on the graph.
To solve the inequality 2y – 4x < 8, we can start by isolating y by adding 4x to both sides:

then divide both sides by 2:
y < 2x + 4
This is the solution in slope-intercept form (y = mx + b), where the slope is m = 2 and the y-intercept is b = 4.
To graph the solution, you can pick a few x-values and substitute them into the inequality to find the corresponding y-values.
You can use x = -2, x = -1, x = 0, x = 1, x = 2, for example and find the y-values for each x, y < 2* -2 + 4 = 0, y < 2* -1 + 4 = 2, y < 20 + 4 = 4, y < 21 + 4 = 6 and y < 2*2 + 4 = 8.

[tex]Answer: t=\boxed{5}\\.\ \ \ \ \ \ \ \ \ \ \ \ u=\boxed{9}[/tex]
Step-by-step explanation:
If ΔGHI=ΔFDE ⇒ we get a system of equations:
[tex]\displaystyle\\\left \{ {{5t+u+12=4u+2t\atop {u-2t+50=13u-9t-23}} \right. \\\\\\\\\left \{ {{3t-3u=-12\ (1)} \atop {7t-12u=-73\ (2)}} \right. \\[/tex]
Divide both parts of the equation (1) by 3:
[tex]\displaystyle\\\left \{ {{t-u=-4} \atop {7t-12u=-73}} \right. \\\\\\\left \{ {{t=u-4} \atop -{7(u-4)-12u=-73}} \right. \\\\\\\left \{ {{t=u-4} \atop {7u+28-12u=-73}} \right. \\\\\\\left \{ {{t=u-4} \atop {-5u=-45\ (3)}} \right.[/tex]
Divide both parts of the equation (3) by (-5):
[tex]\displaystyle\\\left \{ {{t=5} \atop {u=9}} \right.[/tex]
