[tex] \boxed{\sf x\degree = 67\degree} [/tex]

Step-by-step explanation:

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

So,

⇒ 43° + 70° + x° = 180°

43° + 70° = 113°:

⇒ 113° + x° = 180°

Substracting 113° from both sides:

⇒ 113° - 113° + x° = 180° - 113°

113° - 113° = 0°:

⇒ x° = 180° - 113°

180° - 113° = 67°:

⇒ x° = 67°

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:

A is point ( 6, -3, 6)

Step-by-step explanation:

Here in this question, we are concerned with finding the coordinates of point A.

Since we do not know the coordinates of point A, let’s represent them as (x,y,z)

By vector properties; Mathematically ;

AB = (7,4,4) - (x , y, z)

Thus; AB = (7-x)i + (4-y)j + (4-z)k

From the question, we are told that AB is also i + 7j -2k

By comparison;

(7-x)i = i

7-x = 1

x = 7-1

x = 6

(4-y)j = 7j

4-y = 7

4-7 = y

y = -3

and lastly

(4-z)k = -2k

4-z = -2

4 + 2 = z

z = 6

So the coordinates of A are (6, -3, 6)

Answer:

x is a 33° angle

Step-by-step explanation:

The two angles are supplementary meaning the measure of both angles adds up to 180°. You can tell they are supplementary because the angle is a straight line. so all you need to do is subtact 147 from. 180 to get the measure of x .

Answer:

x+147=180 ( sum of supplementary angle)

or, x = 180-147

or, x = 33

so the value of x is 33°

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].

Step-by-step explanation:

The general form of a solution of the differential equation is already provided for us:

[tex]y(x) = c_1 \textrm{e}^x + c_2\textrm{e}^{-x},[/tex]

where [tex]c_1, c_2 \in \mathbb{R}[/tex]. We now want to find a solution [tex]y[/tex] such that [tex]y(-1)=3[/tex] and [tex]y'(-1)=-3[/tex]. Therefore, all we need to do is find the constants [tex]c_1[/tex] and [tex]c_2[/tex] that satisfy the initial conditions. For the first condition, we have:[tex]y(-1)=3 \iff c_1 \textrm{e}^{-1} + c_2 \textrm{e}^{-(-1)} = 3 \iff c_1\textrm{e}^{-1} + c_2\textrm{e} = 3.[/tex]

For the second condition, we need to find the derivative [tex]y'[/tex] first. In this case, we have:

[tex]y'(x) = \left(c_1\textrm{e}^x + c_2\textrm{e}^{-x}\right)' = c_1\textrm{e}^x - c_2\textrm{e}^{-x}.[/tex]

Therefore:

[tex]y'(-1) = -3 \iff c_1\textrm{e}^{-1} - c_2\textrm{e}^{-(-1)} = -3 \iff c_1\textrm{e}^{-1} - c_2\textrm{e} = -3.[/tex]

This means that we must solve the following system of equations:

[tex]\begin{cases}c_1\textrm{e}^{-1} + c_2\textrm{e} = 3 \\ c_1\textrm{e}^{-1} - c_2\textrm{e} = -3\end{cases}.[/tex]

If we add the equations above, we get:

[tex]\left(c_1\textrm{e}^{-1} + c_2\textrm{e}\right) + \left(c_1\textrm{e}^{-1} - c_2\textrm{e} \right) = 3-3 \iff 2c_1\textrm{e}^{-1} = 0 \iff c_1 = 0.[/tex]

If we now substitute [tex]c_1 = 0[/tex] into either of the equations in the system, we get:

[tex]c_2 \textrm{e} = 3 \iff c_2 = \dfrac{3}{\textrm{e}} = 3\textrm{e}^{-1.}[/tex]

This means that the solution obeying the initial conditions is:

[tex]\boxed{y(x) = 3\textrm{e}^{-1} \times \textrm{e}^{-x} = 3\textrm{e}^{-x-1}}.[/tex]

Indeed, we can see that:

[tex]y(-1) = 3\textrm{e}^{-(-1) -1} = 3\textrm{e}^{1-1} = 3\textrm{e}^0 = 3[/tex]

[tex]y'(x) =-3\textrm{e}^{-x-1} \implies y'(-1) = -3\textrm{e}^{-(-1)-1} = -3\textrm{e}^{1-1} = -3\textrm{e}^0 = -3,[/tex]

which do correspond to the desired initial conditions.

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:

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:

Paloma and Abdul combined spent 4 hours more working on the project than Ben and Min combined.

Step-by-step explanation:

Note: This question is not complete as the bar chart is not included. The bar chart is therefore included before answering the question. Please, see the attached jpeg file for the bar chart.

The explanation to the answer is now given as follows:

From the bar chart, we have the number of hours each student spends working on the group project as follows:

Numbers of hours spent by Paloma = 21 hours

Numbers of hours spent by Adbul = 18 hours

Numbers of hours spent by Ben = 13 hours

Numbers of hours spent by Min = 22 hours

The number of hours each group spent working on the group project is calculated as follows:

Numbers of hours spent by Paloma and Abdul = Numbers of hours spent by Paloma + Numbers of hours spent by Paloma = 21 hours + 18 hours = 39 hours

Numbers of hours spent by Ben and Min = Numbers of hours spent by Ben + Numbers of hours spent by Min = 13 hours + 22 hours = 35 hours

Th number of hours Paloma and Abdul spend working on the project combined more than Ben and Min combined = Numbers of hours spent by Paloma and Abdul - Numbers of hours spent by Ben and Min = 39 hours - 35 hours = 4 hours

Therefore, Paloma and Abdul combined spent 4 hours more working on the project than Ben and Min combined.

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]
