The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by

Expression; [tex]\rm \dfrac{4+2i}{8-3i}[/tex]

A complex conjugate is formed by changing the sign between two terms in a complex number i.e. a+ ib has conjugate a-ib and a- ib has conjugate like a+ ib.

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

[tex]=\rm \dfrac{4+2i}{8-3i}\\\\= \rm \dfrac{4+2i}{8-3i}\times \dfrac{8+3i}{8+3i}\\\\= \dfrac{(4+2i) \times (8+3i)}{(8)^2-(-3i)^2}\\\\= \dfrac{32+12i+16i+6i^2}{64+9}\\\\=\dfrac{32+28i+6i^2}{73}[/tex]

Hence, The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

Answer:

[tex]h=\frac{2A}{b}[/tex]

Step-by-step explanation:

[tex]A=\frac{1}{2}bh[/tex]

Switch sides:

[tex]\frac{1}{2}bh=A[/tex]

Multiply both sides by 2:

[tex]2\cdot \frac{1}{2}bh=2A[/tex]

[tex]bh=2A[/tex]

Divide both sides by b:

[tex]\frac{hb}{b}=\frac{2A}{b}[/tex]

[tex]h=\frac{2A}{b}[/tex]

Answer:

Step-by-step explanation:

If there are 27 total cards to be played in a cards of game and each player collects 4carda, the total number of people in the game = Total number of card/amount of card received per person.

total number of people in the game = 27/4 = 6 Remainder 3

The amout of card remaining will be 27-6(4)

= 27-24

= 3

The amount of card remaining is 3 cards

Answer and explanation:

The domain would be [-11,10). -11 has a bracket because there is a closed circle for -11; while 10 only has a parenthesis because there is an open circle. You can use every number between -11 and 10, including -11 (because of the closed circle).

Answer:

x is greater than or equal to -11 and less than 10.

Step-by-step explanation:

On the left it is a solid filled in dot which includes the -11 and on the right the dot is open so 10 is not included.

Answer: the answer is true

Step-by-step explanation:

Answer:

x=6

Step-by-step explanation:

The equation we start with is

4x-6+4=2x+10

First combine like terms

4x-2=2x+10

Next subtract 2x from both sides so that the variable is only on the left side

2x-2=10

Now add 2 to both sides to isolate your variable

2x=12

Finally divide both sides by 2 to find your answer

x=6

Answer:

Step-by-step explanation:

The surface area of a sphere (which the earth is considered to be) = 4 pi r^2

pi = 3.14

r = 6340

Area = 4 * 3.14 * 6340 * 6340 = 504856736 square km.

You should either round this to 505,000,000 or express a value in scientific notation.

Answer:

1st Option.

Step-by-step explanation:

f(0) = g(0) is correct because both f(0) = -2 and g(0) = -2; they both intersect at that point and therefore the y-value is the same.

The other answer choices don't work because the y-value outputs don't match each other.

Answer:

x = 4y - 4/3

Step-by-step explanation:

Step 1: Write expression

Step 2: Subtract 4 on both sides

3x = 12y - 4

Step 3: Divide both sides by 3

x = 4y - 4/3

Answer:

Step-by-step explanation:

the product of 9 and t is:  9•t

the sum of t and 2 is:   t+2

increasing means adding, so:

the product of 9 and t increased by the sum of t and 2 would be:

9t + (t + 2) = 9t + t + 2  = 10t +2
