Given:

[tex]\dfrac{5}{6+2i}[/tex]

To find:

The  quotient in the form a + bi.

Solution:

We have,

[tex]\dfrac{5}{6+2i}[/tex]

Multiply numerator and denominator by 6-2i.

[tex]=\dfrac{5\times (6-2i)}{(6+2i)\times (6-2i)}[/tex]

[tex]=\dfrac{5(6)+5(-2i)}{6^2+(2i)^2}[/tex]

[tex]=\dfrac{30-10i}{36+4i^2}[/tex]

[tex]=\dfrac{30-10i}{36+4(-1)}[/tex]    [tex][\because i^2=-1][/tex]

On further simplification, we get

[tex]=\dfrac{30-10i}{36-4}[/tex]

[tex]=\dfrac{30-10i}{32}[/tex]

[tex]=\dfrac{30}{32}-\dfrac{10i}{32}[/tex]

[tex]=\dfrac{15}{16}+(-\dfrac{5}{16})i[/tex]

Therefore, the form a+bi is [tex]\dfrac{15}{16}+(-\dfrac{5}{16})i[/tex], where, [tex]a=\dfrac{15}{16}[/tex] and [tex]b=(-\dfrac{5}{16})[/tex].

Answer:

  8m³ -4m² +3m

Step-by-step explanation:

The perimeter of a triangle is the sum of the lengths of its three sides. Here, you're given the perimeter and two of the sides. The third side will be the length that makes up the difference.

  P = side 1 + side 2 + side 3

  18m³ +2m² -m = (5m³ +3m² -2m) +(5m³ +3m² -2m) + side 3

  18m³ +2m² -m = (10m³ +6m² -4m) + side 3 . . . . . collect terms

  18m³ +2m² -m - (10m³ +6m² -4m) = side 3 . . . . . subtract (10m³ +6m² -4m)

  m³(18 -10) +m²(2 -6) +m(-1 +4) = side 3 . . . . . . . . . group like terms

  8m³ -4m² +3m = side 3

The sorted inputs in order from least to greatest is:

0.27 < 35% < 27 < 35

Step-by-step explanation:

Given the data

0.27, 27, 35%, 35

as

so Rewriting these inputs as decimals:

0.27, 27, 0.35, 35

Sorting this table by decimal values in order from least to greatest:

0.27    35%        27       35

0.27  <  0.35    <  27  <   35

Thus, the sorted inputs in order from least to greatest is:

0.27 < 35% < 27 < 35

Answer:

Answer:

Step-by-step explanation:

(2x - 2) - 2x > (4x + 6) - 2x

-2 > 2x + 6

(-2) - 6 > (2x + 6) - 6

-8 > 2x

-8/2 > (2x)/2

-4 > x

Answer:

x < - 4

Step-by-step explanation:

2x - 2 > 4x + 6 ( subtract 4x from both sides )

- 2x - 2 > 6 ( add 2 to both sides )

- 2x > 8

divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

x < - 4

The quadratic function that includes the set of values is y = -2x^2 + 7x + 6

The set of values is given as

(0,6) (2,12) (3,9)

A parabola is represented as

y = ax^2 + bx + c

At (0, 6), we have

6 = a(0)^2 + b(0) + c

This gives

c = 6

So, we have

y = ax^2 + bx + 6

At (2, 12), we have

12 = a(2)^2 + b(2) + 6

This gives

4a + 2b = 6

At (3, 9), we have

9 = a(3)^2 + b(3) + 6

This gives

9a + 3b = 3

Using a graphing tools, we have

a = -2 and b = 7

So, we have

y = -2x^2 + 7x + 6

Hence, the quadratic function that includes the set of values is y = -2x^2 + 7x + 6

The given statement is false because the total number of toes and fingers are 30 and not 35.

We are told that If a thumb is a finger, then three gloves and three shoes normally hold thirty-five fingers and toes.

Now, we know that a glove has space for 5 fingers. This means that three gloves would have a total of; 5 * 3 = 15 fingers

Now, a shoe has space for 5 toes. Thus;

Three shoes would have a total of; 5 * 3 = 15 toes

Thus;

Total fingers and toes = 15 + 15 = 30

Thus, we conclude that the given statement is false because the total number of toes and fingers are 30 and not 35.

The angular speed of the bicycle's wheels that are traveling at 25 mi/h is 1885.7 rad/min

To solve this angular speed problem the formula and the procedure we will use is:

v = w * r

Where:

Information about the problem:

Calculating the radius of the wheel, we have:

r = d/2

r = 28 inch/2

r = 14 inch

Converting the velocity unit from mi/h to inch/min, we get:

25 mi/h * (63360 inch / 1 mi) * (1h / 60 min) = 26400 inch/min

Applying the tangential velocity formula and isolating the angular velocity, we get:

v = w * r

w = v / r

w = 26400 inch/min / 14 inch

w = 1885.7 rad/min

When an object is in uniform circular motion, the angle described by the radius in each unit of time is known as angular speed. It is measured in units of (rad/s) (revolutions/s).

[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]

[tex]x=1,\:y=-3[/tex]

As the system of equations has only one solution, thus the solution consistent.

Step-by-step explanation:

Given the system of equations

4x - 5y = 19

y = x - 4

Solving the system of equations by using the substitution method.

[tex]\begin{bmatrix}4x-5y=19\\ y=x-4\end{bmatrix}[/tex]

[tex]\mathrm{Subsititute\:}y=x-4[/tex]

[tex]\begin{bmatrix}4x-5\left(x-4\right)=19\end{bmatrix}[/tex]

[tex]4x-5\left(x-4\right)=19[/tex]

[tex]-x+20=19[/tex]

isolate x for [tex]-x+20=19[/tex]

[tex]-x+20=19[/tex]

[tex]-x=-1[/tex]

Divide both sides by -1

[tex]\frac{-x}{-1}=\frac{-1}{-1}[/tex]

[tex]x=1[/tex]

[tex]\mathrm{For\:}y=x-4[/tex]

[tex]y=-3[/tex]

[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]

Step-by-step explanation:

The constant of Proportionality of wins to loses is 12.

Given, The total no. of games won by team is 84 and the team loses 6 games in the season.

When two or more parameters are directly or indirectly proportional to one another, their relationship is expressed as a = kb or a = k/b, where k indicates how the two variables are related. This k is known as the proportionality constant.

So, let a = Total no. of games won by team

and b = no. of games lost by team

So, proportionality constant (k) = Total no. of games won by team(a)  / no. of games lost by team(b)

k = 84/6

k = 12.

Hence, the proportionality constant is 12.

The linear function is;

Tn-1 = Tn + 3

What this mean is that to get the term before the present term, we add 3 to the present term

Step-by-step explanation:

Here, we want to write a liner function to describe the function

As we can see from the numbers listed,

the next term is simply obtained by deducting 3 from the previous term

We can write this as:

Tn-1 = Tn + 3

Where Tn is the next term and Tn-1 is the previous term

What the function is saying is that to get the term before the present term, we add 3 to the present term

Answer:

the cost of one sweater is $40

Step-by-step explanation:

The computation of the cost of the one sweater is shown below;

Let us assume the sweater be x

And, the pant be y

Now the equations are

2x + y = $120 ..............(1)

x + 2y = $120................(2)

Now multiply by 2 in equation 1

4x + 2y = $240

x + 2y = $120

3x = $120

x = $40

Hence, the cost of one sweater is $40

Answer:

The growth rate is 0.6

The growth factor is 1.6

Step-by-step explanation:

Generally, the exponential equation can be written as;

y = a(1 + r)^x

Where a is the initial value of 100

r is the growth rate

So let us form equations;

160 = 100(1 + r)^1 •••••(i)

Also;

256 = 100(1 + r)^2 •••••••(ii)

Divide equation ii by i

256/160 = 1 + r

1.6 = 1 + r

r = 1.6-1

r = 0.6
