The Taylor series of the function is the sum of derivatives of the function up to infinite.
The Taylor series for a function f(x) centered at a is given by:
f(x) = f(a) + f'(a)(x-a) + f''(a)(x-a)^2/2! + f'''(a)(x-a)^3/3! + ...
To find the Taylor series for f(x) = In(x) centered at a = In(9), we can plug in the values into the formula above:
In(x) = In(9) + In'(9)(x-In(9)) + In''(9)(x-In(9))^2/2! + In'''(9)(x-In(9))^3/3! + ...
= In(9) + (1/9)(x-In(9)) - (1/81)(x-In(9))^2 + (1/729)(x-In(9))^3 + ...
This is the Taylor series for f(x) = In(x) centered at a = In(9).

what is half of 7 3/4 on a tape measure
So, the half of [tex]7\frac{3}{4}[/tex] is [tex]3\frac{7}{8}[/tex]. An improper fraction is a fraction where the numerator is greater than or equal to the denominator.
A fraction is a numerical value that represents a part of a whole. It is typically written as a ratio of two numbers, with a line separating the numerator and the denominator. For example, the fraction one-half can be written as 1/2. Fractions are often used to represent a part of a whole number or a part of a whole object, such as a pie that has been cut into several pieces.
To find half of 7 3/4 on a tape measure, we need to follow these steps:
Convert the mixed number 7 3/4 to an improper fraction. This can be done by multiplying the whole number, 7, by the denominator of the fraction, 4, and adding the numerator, 3, to the product. This gives us 7 x 4 + 3 = 31. So, 7 3/4 is equal to 31/4.Divide the numerator of the improper fraction by 2 to find half of the original mixed number. In this case, we divide 31 by 2 to get 31/2.Convert the resulting improper fraction, 31/2, back into a mixed number. To do this, we divide the numerator, 31, by the denominator, 2, and write the remainder, 1, as the numerator of the fraction part of the mixed number. This gives us the final answer of 3 7/8.Learn more about improper fraction, here https://brainly.com/question/21449807

Angel Sum Theorem PLEASE HELP with explanation if possible
Answer:
y = 90°
Step-by-step explanation:
You want the value of y in the diagram showing y as the angle at the base where the isosceles triangle a.pex angle bisector meets the base.
Angle sum theoremThe angle sum theorem tells you the sum of angles in a triangle is 180°.
Consider the large outside triangle. The sum of its angles is ...
60° +2x +60° = 180°
2x = 60° . . . . . . . . . . . . subtract 120°
x = 30° . . . . . . . . . . divide by 2
Now, consider the left smaller triangle. The sum of its angles is ...
60° +x +y = 180°
60° +30° +y = 180° . . . . . . use the known value of x
y = 90° . . . . . . . . . . . . subtract 90°
__
Additional comment
The a.pex angle bisector of an isosceles triangle is always an altitude that meets the base at right angles. The meeting point is the midpoint of the base, so that segment is also a median.
The halves of the isosceles triangle are congruent right triangles, so the base angle is complementary to the angle marked x.
If y varies directly with x what is the equation when y=-64andx=16
Answer: when y = -64 and x = 16 is y = -4x. This equation states that for every value of x, the corresponding value of y is equal to -4 times the value of x.

What is a function in mathematics?
In mathematics, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. The set of inputs is called the domain of the function, and the set of possible outputs is called the range of the function.
First, factorize the function f(x):
[tex]f(x)=4x^7+40x^6+100x^5\\\\f(x)=4x^5(x^2+10x + 25)\\\\f(x)=4x^5(x+5)^2[/tex]
When f(x)=0, you get that
[tex]4x^5(x+5)^2 = 0\\\\x=0 $ or $ x = -5[/tex]
This means that the graph intersects the x-axis at points (0,0) and (-5,0). But:
1. since the degree at term [tex]x^5[/tex] is odd, point (0,0) is x-intercept;
2. since the degree at term [tex](x+5)^2[/tex] is even, point (-5,0) is the tangent point (see the attached graph of the function).
Hence, The graph crosses the x-axis at x = 0 and touches the x-axis at x = –5.

a jet airliner travels 1680 miles in 3 hours with a tail wind. the return trip, into the wind, takes 3.5 hours. write a system of equations whose solution is the ground speed of the airplane and the wind speed.
A system of equation is 1680mi3hr = p−w×600×2hr -p + w for a jet airliner travels 1680 miles in 3hours with a tail wind.
Let p be the speed of the jet airliner
and w be the speed of the tail wind
It takes the plane 3 hours to go 1680 miles when a jet airliner travels with a tail wind and and 3.5 hours to go 1680 miles against the wind.. So, using system of equations we get
1680mi3hr = p−w×600×2hr = p + w
Solving for the left sides we get:
200mph = p - w
300mph = p + w
Now solve for one variable in either equation, we use
200mph = p - w
Add w to both sides:
p = 200mph + w
Using the value of x, we can found the value of w using system of equations.
300mph = (200mph + w) + w
Combine like terms:
300mph = 200mph + 2w
Subtract 200mph on both sides:
100mph = 2w
On dividing by 2:
50mph = w
So the speed of the tail wind is 50mph.
Therefore, 200mph = p - 50mph
Add 50mph on both sides:
250mph = p
Hence, speed of jet airliner is 250mph.

What is the slope of the line that passes through the points(3,−3) and(18,−3)? Write your answer in simplest form.
Answer: (3, -3) and (18, -3) is 0
Step-by-step explanation:
The slope of a line is a measure of the line's steepness, and it is calculated by taking the difference in the y-coordinates of two points on the line, divided by the difference in their x-coordinates. In this case, the line passes through the points (3, -3) and (18, -3), and the y-coordinates of both points are -3. Therefore, the difference in the y-coordinates is 0, and the slope of the line is 0.
To write this answer in simplest form, we can simply express the slope as 0/1, which can be simplified to 0. Therefore, the slope of the line that passes through the points (3, -3) and (18, -3) is 0.

The Theoretical yield of solid precipitate is 1.42g/mol
Now, consider solid precipitate as cacl2
let us take the mass of cacl2 and calculate the moles of cacl2.
Mass of CaCl2 =2.0 g
By, default the molar mass of CaCl2 =110.98 g/mol
To calculate the Moles we have a formula:
Moles=Given mass*1 mol/Molar mass of a precipitate.-----(1)
substitute the values in equation (1)
Moles of CaCl2 =2.0 g * 1 mol/110.98g
= 0.018 mol
Take another solid precipitate:
Mass of K2Co3=2.0 g
The molar mass of K2Co3 =138.205 g/mol
Now calculating the moles of K2Co3
substitute the values in equation(1)
Moles of K2Co3 =2.0 g * 1 mol/ 138.205g
=0.0145 moles
According to balanced equation 1mole of CaCl2 reacts with 1 mole of K2CO
Thus, 0.018 moles of CaCl2 will react with 0.018 moles of K2CO3
And,0.0145 moles of K2CO3 will produce 0.0145 moles of CaCO3
Molar mass of CaCO3 =100.0869 g/mol
Theoretical yield of CaCO3 =moles of CaCO3 *molar mass of CaCO3

let the denominator of the fraction be x then the numerator is x - 1 , so
original fraction is
[tex]\frac{x-1}{x}[/tex]
if 1 is added to the numerator and 5 to the denominator , then fraction is
[tex]\frac{-1+1}{x+5}[/tex] = [tex]\frac{x}{x+5}[/tex]
equate this to [tex]\frac{1}{2}[/tex]
[tex]\frac{x}{x+5}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2x = x + 5 ( subtract x from both sides )
x = 5
then original fraction is
[tex]\frac{x-1}{x}[/tex] = [tex]\frac{5-1}{5}[/tex] = [tex]\frac{4}{5}[/tex]

an 7.40-cm-diameter, 370 g solid sphere is released from rest at the top of a 2.00-m-long, 19.0 ∘ incline. it rolls, without slipping, to the bottom.
The angular velocity of the sphere at the bottom of the incline is 88.1 rad/s.
What is angular velocity?In physics, angular velocity or angular speed, also recognized as angular frequency vector, is a pseudovector portrayal of how fast the angular position or orientation of an object changes over time.
So, angular velocity will be:
mg(h sinθ) = 1/2 Iω² + 1/2mv²
I of solid sphere = 2/5 mr²
Hence,
mg(h sinθ) = 1/2 (2/5 mr²) ω² + 1/2 mv²
Now remove the mass:
g h sin θ = 1/5 r² ω² + 1/2 v²
ω = v/r, v = ωr
Now, calculate angular velocity as follows:
g h sin θ = 1/5 r² ω² + 1/2 (ωr)²
g h sin θ = (7/10) r² ω²
ω² = 10 g h sin θ/7 r²
ω = √10 g h sin θ/7 r²
= √10 (9.8) (2.1) sin 25° / 7 (0.04)²
= 88.1 rad/s
Therefore, the angular velocity of the sphere at the bottom of the incline is 88.1 rad/s.
