The answer is ,  the Taylor series (centered at c=0) for the function f(x) = e^(4x) is given by:

\($$\large f(x) = \sum_{n=0}^{\infty} \frac{4^n}{n!}x^n$$\)

The Taylor series expansion is a way to represent a function as an infinite sum of terms that depend on the function's derivatives.

The Taylor series of a function f(x) centered at c is given by the formula:

\(\large f(x) = \sum_{n=0}^{\infty} \frac{f^{(n)}(c)}{n!}(x-c)^n\)

Using the definition of Taylor series to find the Taylor series (centered at c=0) for the function f(x) = e^(4x), we have:

\(\large e^{4x} = \sum_{n=0}^{\infty} \frac{e^{4(0)}}{n!}(x-0)^n\)

\(\large e^{4x} = \sum_{n=0}^{\infty} \frac{4^n}{n!}x^n\)

Therefore, the Taylor series (centered at c=0) for the function f(x) = e^(4x) is given by:

The Taylor series for f(x) = e^(4x) centered at c = 0 is:

f(x) = 1 + 4x + 8x^2 + 32x^3/3 + ...

To find the Taylor series for the function f(x) = e^(4x) centered at c = 0, we can use the definition of the Taylor series. The general formula for the Taylor series expansion of a function f(x) centered at c is given by:

f(x) = f(c) + f'(c)(x - c) + f''(c)(x - c)^2/2! + f'''(c)(x - c)^3/3! + ...

First, let's find the derivatives of f(x) = e^(4x):

f'(x) = d/dx(e^(4x)) = 4e^(4x)

f''(x) = d^2/dx^2(e^(4x)) = 16e^(4x)

f'''(x) = d^3/dx^3(e^(4x)) = 64e^(4x)

Now, let's evaluate these derivatives at x = c = 0:

f(0) = e^(4*0) = e^0 = 1

f'(0) = 4e^(4*0) = 4e^0 = 4

f''(0) = 16e^(4*0) = 16e^0 = 16

f'''(0) = 64e^(4*0) = 64e^0 = 64

Now we can write the Taylor series expansion:

f(x) = f(0) + f'(0)(x - 0) + f''(0)(x - 0)^2/2! + f'''(0)(x - 0)^3/3! + ...

Substituting the values we found:

f(x) = 1 + 4x + 16x^2/2! + 64x^3/3! + ...

Simplifying the terms:

f(x) = 1 + 4x + 8x^2 + 32x^3/3 + ...

Therefore, the Taylor series for f(x) = e^(4x) centered at c = 0 is:

f(x) = 1 + 4x + 8x^2 + 32x^3/3 + ...

The series converges absolutely since there exist a p-series with p=6, and since p>1, therefore series converges absolutely.

To determine whether the series ∑(n=1 to infinity) (−1)^n(1 + 1/n^6) converges absolutely, conditionally, or not at all, we need to analyze the terms of the series.

First, let's check for absolute convergence. To do this, we take the absolute value of the terms in the series:
| (−1)^n(1 + 1/n^6) | = | (−1)^n | * | 1 + 1/n^6 |

Since | (−1)^n | = 1, this simplifies to:
| 1 + 1/n^6 |

Now, we need to test this new series for convergence. We can use the comparison test, by comparing it to the series ∑(n=1 to infinity) (1/n^6), which is a p-series with p = 6.

Since 6 > 1, the p-series converges, and because 1 + 1/n^6 > 1/n^6 for all n, the original series also converges absolutely.

Therefore, the series ∑(n=1 to infinity) (−1)^n(1 + 1/n^6) converges absolutely.

The dimensions of the TV set are height = 20 inches and length = 48 inches.

The given statement is:

The diagonal of a TV set is 52 inches long.

Its length is 28 inches more than the height.

Find the dimensions of the TV set.So, we have to find the dimensions of the TV set.

Length = Height + 28 (Because length is 28 inches more than the height)

The diagonal of the TV set = 52 inches

Using Pythagoras theorem, we can find the dimensions of the TV set.

The Pythagorean Theorem is:In a right-angled triangle:the square of the hypotenuse is equal to the sum of the squares of the other two sides.(or)h² = b² + c².

Here,The diagonal is the hypotenuse.

The height is b and the length is c.

We have to find the height and length.

Using Pythagorean theorem:h² = b² + c²

52² = b² + (h+28)²

By putting the value of length in the above equation we get:

2704 = b² + h² + 56h + 7840

= b² + h² + 56h - 270436

= b² + h² + 56h

Divide each term by 4:

(b²)/4 + (h²)/4 + (14h)/7 = 9

The dimensions of the TV set are:

height = b = 4sqrt(9 - (h+2)²/49)

length = c = 4sqrt(9 - (h+30)²/49)

By substituting h = -21 in the above equations,we get:

height = b = 20 inches

length = c = 48 inches

For the maximum volume of , the value of x must be smaller that is x = 2.90 inch. Size of square = 8.41 sq. in.

The issue is an application of maxima and minima, where the unknown quantity is located using the first derivative. Keep in mind that the height of a box is equal to a side of the cut square when the sides are bent upward. Moreover, the box formula's volume is

Volume = length * width * height

Given:

Volume of new box = (32 - 2x)(12 - 2x)x

Rearranging terms:

V = 4x³ - 88x² + 384x

For maximum volume, V' = 0 (first derivative)

V' = 12x² - 167x + 384

V' = 0

12x² - 167x + 384 = 0

Solve using quadratic formula:

x = [-b ± √(b² - 4ac)] / 2a

a = 12 , b = - 167 , c = 384

x = [167 ± √(167² - 4*384*12)] / 2*12

x =  [167 ± 7√193] / 24

Now,

x =  [167 + 7√193] / 24

x = 11.01 inch

Answer:

(-5,8)

Step-by-step explanation:

The given equation y = -3x - 7 holds true for the ordered pair, so (-5, 8) is a solution. Thus, option third is correct.

To determine whether each ordered pair is a solution to the equation y = -3x - 7, we substitute the x and y values into the equation and check if it holds true.

For the ordered pair (8, -56):

y = -3x - 7

-56 = -3(8) - 7

-56 = -24 - 7

-56 = -31

The equation does not hold true for this ordered pair, so (8, -56) is not a solution.

For the ordered pair (-5, 8):

y = -3x - 7

8 = -3(-5) - 7

8 = 15 - 7

8 = 8

The equation holds true for this ordered pair, so (-5, 8) is a solution.

For the ordered pair (-9, -23):

y = -3x - 7

-23 = -3(-9) - 7

-23 = 27 - 7

-23 = 20

The equation does not hold true for this ordered pair, so (-9, -23) is not a solution.

For the ordered pair (4, 19):

y = -3x - 7

19 = -3(4) - 7

19 = -12 - 7

19 = -19

The equation does not hold true for this ordered pair, so (4, 19) is not a solution.

If line q passes through points (1,5) and (8, 2). line r is perpendicular to q, Then the slope of line r is 7/3.

The slope of a line is a measure of how steep the line is, or how much the line rises or falls as we move horizontally along it. It is defined as the ratio of the change in the vertical (y) coordinate to the change in the horizontal (x) coordinate between any two points on the line. In other words, it is the "rise" divided by the "run".

The formula for finding the slope between two points (x1, y1) and (x2, y2) on a line is:

slope = (y2 - y1) / (x2 - x1)

The slope can be positive, negative, zero or undefined. A positive slope means the line rises as we move from left to right, a negative slope means the line falls as we move from left to right, a slope of zero means the line is horizontal and a slope that is undefined means the line is vertical.

The slope of the line q passing through the points (1,5) and (8,2) can be found using the slope formula:

the slope of q = (change in y) / (change in x)

= (2 - 5) / (8 - 1)

= -3/7

Since line r is perpendicular to line q, the slope of line r will be the negative reciprocal of the slope of line q. That is:

the slope of r = -1 / slope of q

= -1 / (-3/7)

= 7/3

Therefore, the slope of line r is 7/3.
