Answer:

The generated Taylor series is;

f(x) = 1/6 + (x-3)/36 + (x-3)^2/216 + (x-3)^3/1296......

Kindly note that the series here is truncated at the third derivative, but if wanted, evaluation could be more than this

Step-by-step explanation:

Here, we are to find the Taylor series generated by f at x = a

Mathematically;

f(x)= 1/(9-x)

The f(a) at this point is calculated below;

f(a) = 1/(9-3) = 1/6

The first derivative is calculated below;

f'(x) = 1/(9-x)^2

f'(3) = 1/6^2 = 36

The second derivative is calculated below;

f''(x) = 2/(9-x)^3

f''(3) = 2/(9-3)^3 = 2/6^3 = 2/216 = 1/108

The third derivative is calculated as follows

f'''(x) = 6/(9-x)^4

f'''(3) = 6/(9-3)^4 = 6/6^4 = 1/216..

The Taylor series is thus given by;

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

Substituting the values of 3 for a at each of the points , we obtain the Taylor series as shown below;

f(x) = 1/6 + (x-3)/36 + (x-3)^2*1/108*1/2 + (x-3)^3*1/216*1/6 +...

f(x) = 1/6 + (x-3)/36 + (x-3)^2/216 + (x-3)^3/1296......

Answer: equation for length 34- (6.5 times 2)  that whole thing divided by 2

Step-by-step explanation:

You know the width and a rectangle has 2 PAIRS of equal sides so if you know the width you just have to multiply that  by 2  [ to account 4 the other side with the same length] and subtract that from the perimeter! Then you divide that answer by 2 to get what one side's length is!

The population is the entire set of registered voters (11100) in the city. This is what the election officials care about, so they won't focus on any other city data.

Inside that population, the much smaller sample is generated to try to make an educated guess about what the population will do. In this case, the sample is the 400 people surveyed. If the sample was generated randomly enough, then it should be unbiased to give a good idea of what the population will do.

Answer:

The correct answer is B :)

Step-by-step explanation:

The difference in the area of shape A and shape B is option B which is [tex]12x^{4}+12x^{3}+26x^{2} +8x+12[/tex].

Area of rectangle and square is the extent of surface rectangle and square exhibits into them. The area of rectangle is length * breadth and the area of square is side*side.

We have been given the length of shape A=[tex]7x^{2} +4x+8[/tex] and breadth be [tex]3x^{2} +2[/tex] and the side of shape B be [tex]3x^{2} +2[/tex].

Shape A looks like rectangle and shape B looks like square.

So the area becomes:

Area of shape A =[tex](3x^{2} +2) ( 7x^{2} +4x+8)[/tex]

we have to multiply both expressions

=[tex]21x^{4} +12x^{3} +24x^{2} +14x^{2} +8x+16[/tex]

=[tex]21x^{4} +12x^{3} +38x^{2}+8x+16[/tex]

Area of shape B=[tex](3x^{2} +2)(3x^{2} +2)[/tex]

=[tex]9x^{4} +6x^{2} +6x^{2} +4[/tex]

=[tex]9x^{4} +12x^{2} +4[/tex]

Difference=[tex]21x^{4}+12x^{3}+38x^{2} +8x+16-9x^{4} -12x^{2} -4[/tex]

=[tex]12x^{4} +12x^{3}+26x^{2} +8x+12[/tex]

Hence the difference between shape A and shape B is [tex]12x^{4} +12x^{3}+26x^{2} +8x+12[/tex].

Answer: x = 60

Step-by-step explanation: Notice that these two angles are vertical angles.

Whenever two lines intersect, a pair of vertical angle is always formed.

Now, vertical angles are always congruent.

So we can setup the equation 2x + 24 = 144.

Solving from here, we first subtract 24 from both sides to get 2x = 120.

Now dividing both sides by 2, we find that x = 60.

So x = 60.

Answer:

c. 60°

Step-by-step explanation:

[tex](2x +24)\° = 144\°\\\\2x+24\°=144\°[/tex]

Collect like terms and simplify

[tex]2x\° =144\°-24\°\\\\2x\°=120\°[/tex]

Divide both sides of the equation by 2 and simplify

[tex]\frac{2x}{2} = \frac{120}{2} \\\\x =60\°[/tex]

Answer:

a) The standard form of [tex]z = 4\cdot (\cos 60^{\circ}+i\cdot \sin 60^{\circ})[/tex] is [tex]z = 2 + i\cdot 2\sqrt{3}[/tex], b) [tex]z = (2+i\cdot 3)^{6} = 1219.585 + i \cdot 1829.381[/tex].

Step-by-step explanation:

a) The standard form of the complex number is [tex]z = a + i\cdot b[/tex], [tex]\forall \,a,b \in \mathbb{R}[/tex]. If we get that [tex]z = 4\cdot (\cos 60^{\circ}+i\cdot \sin 60^{\circ})[/tex], whose standard form is obtained by algebraic means:

1) [tex]z = 4\cdot (\cos 60^{\circ}+i\cdot \sin 60^{\circ})[/tex] Given

2) [tex]z = (4\cdot \cos 60^{\circ})+i\cdot (4\cdot \sin 60^{\circ})[/tex] Distributive and Associative properties.

3) [tex]z = 2 + i\cdot 2\sqrt{3}[/tex] Multiplication/Result.

The standard form of [tex]z = 4\cdot (\cos 60^{\circ}+i\cdot \sin 60^{\circ})[/tex] is [tex]z = 2 + i\cdot 2\sqrt{3}[/tex].

b) The De Moivre's Theorem states that:

[tex]z = (a+i\cdot b)^{n}= r^{n}\cdot (\cos \theta + i\cdot \sin \theta)[/tex]

Where:

[tex]r =\sqrt{a^{2}+b^{2}}[/tex] and [tex]\theta = \tan^{-1} \left(\frac{b}{a}\right)[/tex].

If we know that [tex]z = (2+i\cdot 3)^{6}[/tex], then:

[tex]r = \sqrt{2^{2}+3^{2}}[/tex]

[tex]r =\sqrt{13}[/tex]

[tex]r \approx 3.606[/tex]

[tex]\theta = \tan^{-1}\left(\frac{3}{2} \right)[/tex]

[tex]\theta \approx 56.310^{\circ}[/tex]

The resulting expression is:

[tex]z = 3.606^{6}\cdot (\cos 56.310^{\circ}+i\cdot \sin 56.310^{\circ})[/tex]

[tex]z = 1219.585+i\cdot 1829.381[/tex]

Therefore, [tex]z = (2+i\cdot 3)^{6} = 1219.585 + i \cdot 1829.381[/tex].

Answer:

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

( -2 , 1) and ( 4,3)

The distance is

[tex]d = \sqrt{( { - 2 - 4})^{2} + ({1 - 3})^{2} } \\ = \sqrt{ ({ - 6})^{2} + ({ - 2})^{2} } \\ = \sqrt{36 + 4} \\ = \sqrt{40} \\ = 2 \sqrt{10} \\ = \:6.324555[/tex]

We have the final answer as

Hope this helps you

Step-by-step explanation:

Hey there!!!

Given, the points are (4,3) and (-2,1).

Then,

x1=4 x2=-2

y1=3 y2=1

Now, Using distance formula,

[tex](distance ) = \sqrt{ {(x2 - x1)}^{2} + ( {y2 - y1)}^{2} } [/tex]

Put all values.

[tex](distance ) = \sqrt{ {( - 2 - 4)}^{2} + {(1 - 3)}^{2} } [/tex]

Simplify them.

[tex](distance ) = \sqrt{( { - 6)}^{2} + ( { - 2)}^{2} } [/tex]

[tex](distance ) = \sqrt{36 + 4} [/tex]

[tex](distance ) = \sqrt{40} [/tex]

(distance )= 6.3245 units.

Therefore, the distance between the points(4,3) and (-2,1) is 6.32units.

So, your answer is option B.
