Find the quadratic approximating polynomial for the following function centered at the given point a. c. Use the polynomials obtained in parts a. and b. to approximate the given quantity. -1/1.06

Answers

Answer 1

The required answers are:

a. The linear approximating polynomial at a = 1: P₁(x) = x - 2

b. The quadratic approximating polynomial at a = 1: P₂(x) = -3 + 3x - x²

c. Appromating the given quantity -1/1.06 for P₁(x) and P₂(x): -3.06 and -7.30 respectively.

Using Taylor polynomial series, the required approximating polynomials are calculated.

What is the Taylor polynomial series?

The Taylor polynomial series is

Pₙ(x) = ∑ [tex]\frac{f^n(a)}{n!}[/tex](x - a)ⁿ; limits from 0 to n

Where fⁿ(a) is the nth derivation of f(x) at a

The first order(linear) Taylor polynomial series is

P₁(x) = f(a) + [tex]\frac{f'(a)}{1!}[/tex](x - a)¹

The second order(quadratic) Taylor polynomial series is

P₂(x) = f(a) + [tex]\frac{f'(a)}{1!}[/tex](x - a) +  [tex]\frac{f''(a)}{2!}[/tex](x - a)²

Calculation:

The given function is f(x) = -1/x at a = 1

f(a) = f(1) = -1

f'(x) = -(-1/x²) = 1/x²; f'(a) = f'(1) = 1

f''(x) = -2/x³; f''(a) = f''(1) = -2

a. Linear approximating polynomial:

From the Taylor series, we have

P₁(x) = f(a) + [tex]\frac{f'(a)}{1!}[/tex](x - a)¹

On substituting,

P₁(x) = -1 + (1/1!)(x - 1)¹

       = -1 + (x - 1)

       = x - 2

b. Quadratic approximating polynomial:

From the Taylor series, we have

P₂(x) = f(a) + [tex]\frac{f'(a)}{1!}[/tex](x - a) +  [tex]\frac{f''(a)}{2!}[/tex](x - a)²

On substituting,

P₂(x) = f(1) + (1/1!)(x - 1) +  (-2/2!)(x - 1)²

        = -1 + (x - 1) - (x - 1)²

        = -1 + x - 1 - (x² - 2x + 1)

        = x - 2 - x² + 2x - 1

        = -3 + 3x - x²

c. Approximating the given quantity -1/1.06:

Substituting x = -1.06 in P₁(x) and P₂(x),

P₁(x) = x - 2

⇒ P₁(-1.06) = (-1.06) - 2 = -3.06

P₂(x) = -3 + 3x - x²

⇒ P₂(-1.06) = -3 + 3(-1.06) - (-1.06)² = -7.30

Therefore, the approximating polynomials are calculated by using Taylor polynomial series.

Based on the information, Christian would have $5525.5 of an annuity.

How to calculate the annuity?

According to the given information, the number of coffees per week is 3 then, per month is 3x4 = 12

Each coffee is $4.5. Then monthly expenditure for coffees is 12 x 4.5 = $54

Rate of interest r = 1.6% = 1.6/100 = 0.016 and for monthly compounding r = 0.016/12 = 0.00133

n = number of payments = 8 x 12 = 96

We can use the formula for finding the future value as below

FV = C x [ ( 1 + r )n-1 ] / ( r )

FV = 54 x [ ( 1 + 0.00133 )96 – 1 ] / (0.00133)

= 54 x [ (1.13609 - 1)] / (0.00133)

= 54 x 0.13609 / (0.00133)

= 54 x 102.3233

4z-10=10 what do i solve for z

Answers

Answer:

z = 5

Step-by-step explanation:

To solve for z, means to get z all by itself on one side of the equation. In your equation z has had two things done to it. First, z has been times by 4, then 10 is subtracted. So, you "un-do" that in reverse order.

FIRST, add 10. To reverse or "un-do" subtracting.

4z - 10 = 10

4z -10+10 = 10+10

4z = 20

Then, divide by 4 to reverse the multiplying.

4z/4 = 20/4

z = 5

see image.

Also, you can check you answer.

put in 5 in place of z and be sure that you get a true statement.

4(5) - 10 = 10

20 - 10 = 10

10 = 10 Checked!

Answer:

[tex]z=5[/tex]

Step-by-step explanation:

First, substitute in 5 for z: [tex]4(5) -10=10[/tex]

Since [tex]4*5=20[/tex], we can now simplify the equation to [tex]20-10=10[/tex].

Now, check the equation to make sure that the value of z is correct. Do this by subtracting [tex]20-10[/tex] to see if it results in a solution of 10.

Since the equation [tex]20-10=10[/tex] is equal/true, we can conclude that [tex]z=5[/tex].

Write a paragraph proof to show that the perimeter of Rectangle 2 is k times the perimeter of Rectangle 1. Write a paragraph proof to show that the area of Rectangle 2 is times the area of Rectangle 1. Answer:

Answers

Yes, the two rectangles are similar, because rectangle 2 is a dilation of rectangle 1.

Are the two rectangles similar?

We know that rectangle 1 has dimensions L and W.

And rectangle 2 is made by multiplying the dimensions of rectangle 1 by a factor k > 0.

Then, rectangle 2 is just a dilation of rectangle 1, this means that in fact, the two rectangles are similar by definition.

Then:

Dimensions of rectangle 1:

Length = LWidth = W.Perimeter = 2*(W + L)Area = W*L

For rectangle 2:

Length = k*LWidth = k*WPerimeter = 2*(k*L + k*W) = k*(2*(L + W))Area = (k*L)*(k*W) = k²(L*W)

Above we can see that the perimeter of rectangle 2 is k times the perimeter of rectangle 1, and the area of rectangle 2 is k squared times the area of the rectangle 1.

Answers

17.49 is the magnitude of the resultant vector. This can be obtained by adding the vectors and finding magnitude.

Calculate the magnitude of the resultant vector:

Resultant vector: vector that gives the combined effect of all the vectors. When we add two or more vectors, the outcome is the resultant vector.

For example,

Sum of vector (3,4) and vector (5,7)

(3,4) + (5,7) = (3+5,4+7) = (8,11)

(8,11) is the resultant vector of vector (3,4) and vector (5,7)

Magnitude of a vector: the length of the vector. The magnitude of the vector a is denoted as ∥a∥.

Magnitude of a = (a₁, a₂)

∥a∥=[tex]\sqrt{a_{1}^{2} +a_{2}^{2} }[/tex]

In the given question,

v (8,10) and w (7, -1)

Adding the vectors,

resultant vector = (8,10) + (7, -1) = (15, 9)

Magnitude of a vector (a,b) = √a²+b²

Here, magnitude = √15²+9² = √225+81 = √306 ≈ 17.49

Hence 17.49 is the magnitude of the resultant vector.

In this particular problem, visualizing the graph isn't actually necessary. You only need to figure out what was added or subtracted to get the new numbers from the old ones.

In the beginning, point D was at the x coordinate 1. To make 1 into -2, you subtract three. The points E and F were also changed from their old numbers to the new ones by subtracting 3.

So, we know that the first half of our rule is x-3.

In the beginning, point D was at the y coordinate 3, but it changed to a 6. To get from 3 to 6, you add three more. Points E and F can also be made into their new numbers by adding 3.

Each intercept is found by solving for the variable after the other variable is set to zero.

X-intercept

Set y = 0 and solve for x:

  -3x = 66

  x = 66/(-3) = -22 . . . . . divide by the coefficient of x

The x-intercept is (-22, 0).

Y-intercept

Set x = 0 and solve for y:

  11y = 66

  y = 66/11 = 6 . . . . . . . . divide by the coefficien tof y

The y-intercept is (0, 6).

__

Additional comment

The given equation is in standard form (almost). This form makes it easy to find the intercepts by dividing the constant by the variable's coefficient, as we did above.

(We say "almost" standard form because the leading coefficient is negative. It would be positive in standard form: 3x -11y = -66.)

Answer: (-22,0) and (0,6) in order

Step-by-step explanation:

x-intercept means point of graph that intersects the x-axis and y=0

y-intercept means point of graph that intersects the y-axis and x=0

So the x-intercept is -3x + 0 = 66 as y = 0

x = -22 so the coordinate is (-22,0)

The y-intercept is 0 + 11y = 66 as x = 0

y = 6 so the y-intercept is (0,6)

To review, an asymptote is a line that the graph of a function approaches, but will never touch. Normally, a horizontal asymptote would limit the range as the graph can never cross a certain y-value.

However, there is no such y-value that must not be crossed in a slant asymptote; therefore, there is not limitation to the range. The range would be all real numbers.

Hence, the range of function h is (-[tex]\infty[/tex], [tex]\infty[/tex]).

Suppose that a rectangular piece of glass has a perimeter of 20 meters. if we multiply both its length and its width by 4, what will be the perimeter of the new rectangular piece of glass?

Answers

The perimeter of the new rectangular piece of glass is 80m.

What is the perimeter of a rectangle?The sum of all sides of a rectangle is the perimeter of the rectangle.A rectangle has two equal lengths and two equal widths.Therefore, the perimeter 'P' of a rectangle is the sum of two equal lengths and two equal widths. That is, 'P=2l+2w' where 'l' is the length and 'w' is the width of the rectangle.

Here, a rectangular piece of glass has a perimeter of 20 meters.

As we know the perimeter P of a rectangle is given by the formula,

P = 2l+2w...(1)

Therefore,

20 = 2l + 2w

20 = 2(l + w)

20/2 = l + w

10 = l + w ....(2)

Now, both the length and width of the rectangle are multiplied by 4,

That is,

The new length of the rectangle is, l = 4l

The new width of the rectangle is, w = 4w

Therefore by substituting this in the equation(1) we get,

P = 2(4l) + 2(4w)

P = 8l + 8w

P = 8(l+w)....(3)

Substitute equation (2) in (3),

That is,

P = 8*10

P = 80m

Answer:

Min: 32

Lower Quartile: 36

Median: 42

Upper Quartile: 47

Max: 53

Interquartile: 11

Step-by-step explanation:

The min. is just the lowest number.  The lower quartile is the number in the middle of the numbers below 42, the median is the number in the very middle, the upper quartile is the middle number above 41 and the interquartile is the upper quartile minus the lower quartile.  

1.an examination in three subjects algebra,biology ,chemistry was taken by 41 students. the following table shows how many students failed in each single subject and their various combinations: subject a b c ab ac bc abc failed 12 5 8 2 6 3 1 how many students failed at least in one subject?

Answers

so since this chart shows which subject a certain number of students failed all of them would fall into the category of failing at least on subject so you just add up all the numbers

30. Isla swims 4 laps in 2 minutes, and 1
lap = 25 meters. Which of the following
calculations would give her average
speed in meters per second?

Answers

The average speed is 50 meters per second

How to determine the average speed?

The given parameters are:

Laps = 4

Time = 2 minutes

1 lap = 25 meters

Start by calculating the total distance

Distance = Laps * Meters

Distance = 4 * 25 meters

Distance = 100 meters

The average speed is then calculated as:

Speed = Distance/Time

This gives

Speed = 100 meters/2 minutes

Evaluate

Speed = 50 meters per second

Hence, the average speed is 50 meters per second
