SOMEONE HELP??????!!!!!!!

Answer:

184/16 = 23/2 = 11 1 /2

Answer:

see below

Step-by-step explanation:

To find the conjugate of a+bi take the opposite of bi so it would be a - bi

7-3i, the conjugate is 7 + 3i

8+2i  the conjugate is 8 -2i

The product of a number and its conjugate is

(a+bi) (a-bi) = a^2 +abi-abi -b^2 i^2 = a^2 - b^2 (-1) = a^2 + b^2

( 4-i) ( 4+i) = 4^2 + 1^2 = 16+1 = 17

( 6+3i)(6-3i) = 6^2 + 3^2 = 36+9 = 45

#1

[tex]\\ \sf\longmapsto \overline{z}=7+3i[/tex]

#2

[tex]\\ \sf\longmapsto \overline{z}=8-2i[/tex]

#3

[tex]\boxed{\sf z\overline{z}=|z|^2}[/tex]

[tex]\\ \sf\longmapsto z=4-i[/tex]

[tex]\\ \sf\longmapsto |z|^2=4^2+(-1)^2[/tex]

[tex]\\ \sf\longmapsto 16+1=17[/tex]

Answer:

Step-by-step explanation:

This is going to give you a preposterous answer. The width is into the millions.

density = 9000 kg / m^3

mass = 0.45 kg

V = density / mass

V = 9000 / 0.45 = 20000 m^3

V = L *w * h

L = 0.5 m

h = 0.01 m

w = ?

20000 = 0.5 * 0.01 * w

20000 / (0.5 * 0.01) = w

w = 4000000 m

Answer:

c³ + 24c² + 192c + 512

Step-by-step explanation:

(c + 8)³

= (c + 8)(c + 8)(c + 8) ← expand last 2 factors using FOIL

= (c + 8)(c² + 16c + 64)

Multiply each term in the second factor by each term in the first factor

c(c² + 16c + 64) + 8(c² + 16c + 64) ← distribute parenthesis

= c³ + 16c² + 64c + 8c² + 128c + 512 ← collect like terms

= c³ + 24c² + 192c + 512

Answer:

[tex]c^{3} + 24 {c}^{2} + 192c + 512 [/tex]

Step-by-step explanation:

Expand the expression

[tex](c + 8)(c + 8)(c + 8) \\ = {c}^{3} + 3 {c}^{2} \times 8 + 3c \times {8}^{2} + {8}^{3} \\ = {c}^{3} + 24 {c}^{2} 3c \times 64 + 512 \\ = {c}^{3} + 24 {c}^{2} + 192c + 512[/tex]

Step-by-step explanation:

11. Angle A and B are supplementary (add to 180)

And measure of Angle A is 2x+30 and measure of angle B is 6x-12. All you have to do is make an algebraic expression.

180= (2x+30) + (6x-12)

Then just combine like terms and you get

8x+18=180.. Subtract 18 and you get

8x=162 then divide by 8 and you get

X=20.25

Then plug in the number and you get

180=(2*20.25+30)+(6×20.25-12)

Which is is transferred to

180=(70.5) +(109.5)

Which is 180=180.

The measure of angleA is 70.5°

You can try the other's if you want if not then

9. Value of x is 33.5

10. Measure of angleB 90°

12. Measure of angleA 24°

Answer: 8x = $39.62 - $6.74

Step-by-step explanation:

Cost of 1 bag of lemons = $x

Cost of 8 bags of lemons = 8*x = 8x

Cost of 8 bags of lemons = Total cost - cost of the egg

8x = $39.62 - $6.74

Answer: 252 decibels

given:

6:5:3 = ratio of L to P to G

P=90

one unit is 90/5 because the five represents a smaller version of 90

one unit = 18

answer=18(6+5+3)=252

brainliest please im sorry this one is late

The answer is 252 decibels

Answer:

14810 votes

Step-by-step explanation:

The canidate won, so that means that they were the 7 instead of the 5.

Then you divide 20734 by 7, to see how many votes were for each "1". That's 2962.

Now you know that every "1" is worth 2962. Since the other candidate got 5, you multiply 5 by 2962 which is 14810.

The other candidate got 14810 votes.

Hope that made sense

Answer:

The other opponent that lost got 14 810 votes.

[tex]\large \mathfrak{Solution : }[/tex]

let the numbers be x and y

now, we know that

by squaring Equation (1) :

Plugging the value of x from Equation (3) into Equation (1)

now, let's plug the value of y from Equation (4) into Equation (3) :

5√2 - √8 = 5√2 - √(4 · 2) =

= 5√2 - √(2² · 2) = 5√2 - 2√2 = 3√2

[tex] \large \mathfrak{Solution : }[/tex]

let's solve :

Answer:

Step-by-step explanation:

The revenue function is given to you, it's just not given in equation form. In equation form, the function is

R(p) = p(120 - 4p)

If we are looking for the number of tickets that causes the revenue to be $0, we replace R(p) with 0 and solve for p.

0 = p(120 - 4p). That means, by the Zero Product Property, that

p = 0 or 120 - 4p = 0 which gives us, when we solve each one of those equations, that

p = 0 or

120 = 4p and

p = 30. The reasoning is the bold statement up above.

The equation we would use to determine the number of tickets needed to sell for the revenue to be $600 will be

600 = p(120 - 4p)

Answer:

Step-by-step explanation:

d =√[(-3+9)²+(6+2)²]

= √(6²+8²)

=√(36+64)

=√100

= 10

Answer:

[tex]\boxed {\boxed {\sf d=10}}[/tex]

Step-by-step explanation:

The distance between two points can be calculated using the following formula.

[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

In this formula, (x₁, y₁) and (x₂, y₂) are the two points. We are given the points (-9, -2) and (-3,6). If we match the value with the corresponding variable we see that:

Substitute the values into the formula.

[tex]d= \sqrt {(-3 - -9)^2 + (6 - -2)^2[/tex]

Solve inside the parentheses. Remember that 2 back to back negative signs become a plus sign.

[tex]d= \sqrt{ (6)^2 + (8)^2[/tex]

Solve the exponents. Multiply the number by itself.

[tex]d= \sqrt{(36)+(64)[/tex]

Add.

[tex]d= \sqrt{100[/tex]

Take the square root of the number.

[tex]d= 10[/tex]

The distance between the points (-9, -2) and (-3, 6) is 10.

Answer:

3-gallon jug of water for $10.92, is the better buy

Step-by-step explanation:

First let's do the 3 gallon jug -

We need to find the unit rate (The cost per gallon/quart)

$10.92 / 3 = $3.64

$8.64 / 8 = $1.08

1 Gallon = 4 Quarts, therefore the 3-gallon jug of water is the better buy.
