Need help kinda stuck on this one!

Answer: The complex conjugate has a very special property. Consider what happens when we multiply a complex number by its complex conjugate. We find that the answer is a purely real number  it has no imaginary part. This always happens when a complex number is multiplied by its conjugate the result is real number.

Real numbers can be positive or negative, and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers

Step-by-step explanation: Every complex number has a complex conjugate. The complex conjugate of a + bi is a - bi. For example, the conjugate of 3 + 15i is 3 - 15i, and the conjugate of 5 - 6i is 5 + 6i.

Answer:

  trisect the median. The centroid is 1/3 its length from the side.

Step-by-step explanation:

The centroid divides each median into parts with a ratio of 2:1. If you trisect the median, the centroid will be 1 unit from the side and 2 units from the vertex.

Answer:

Step-by-step explanation:

SA = 2*pi*r^2 + 2pi*r*h

= 2pi*r(r+h)

r = 7 and h = 12

2*pi*7(7+12) = 14pi*19=266pi

Answer:

  ∠QPS = 101°

  ∠PSR = 79°

Step-by-step explanation:

The marked angles are called "same-side interior angles" or "consecutive interior angles". By either name, they are supplementary.

  (2k +89) +(3k +61) = 180

  5k +150 = 180 . . . . . . . . . collect terms

  5k = 30 . . . . . . . . . subtract 150

  k = 6 . . . . . . . divide by 5

Then the angles are ...

  ∠QPS = (2·6 +89)° = 101°

  ∠PSR = (3·6 +61)° = 79°

Answer:

∠QPS = 2 x 6 + 89 =101°

∠PSR = 3 x 6 + 61 =79°

Step-by-step explanation:

∠QPS and ∠PSR are consecutive interior angles, they are supplementary

(2k+89) + (3k+61) = 180

5k + 150 = 180

5k = 180-150 = 30

k = 6

∠QPS = 2 x 6 + 89 =101

∠PSR = 3 x 6 + 61 =79

Answer:

see explanation

Step-by-step explanation:

Using the rule of exponents

[tex](a^m)^{n}[/tex] ⇔ [tex]a^{mn}[/tex]

That is each exponent of the terms inside the parenthesis is multiplied by the exponent outside the parenthesis

[tex](xy^{4}) ^{6}[/tex]

= [tex]x^{1(6)}[/tex] [tex]y^{4(6)}[/tex]

= [tex]x^{6}[/tex] [tex]y^{24}[/tex]

Answer:

1/6

Step-by-step explanation:

Slope is calculated as rise over run. Rise is the change in the y-axis while run is the change in the x-axis.

The two coordinates are (-2, -3) and (4, -2).

From (-2, -3), if you go up 1 unit, you would be at (-2, -2). If you go to the right 6 units, you would be at (4, -2).

So, the slope is 1/6.

Hope that helps.

Answer:

A = P ( 1+ i )^n

A = 10,000(1+0.025)^10

= 10,000(1.025)^10

= $12,800.84

Step-by-step explanation:

A = future amount

i = interest rate

n = number of years

P = Present value

i.e i = 2.5% , P = $10,000 and n = 10 years

Answer:51

Step-by-step explanation:102 beats : 2 min

                                              ?beats       :1 min

               Do 102 times 1 which gives you 102 .Then divide by 2 and you get 51.

Hope it helps. :)

102 beats per 2 minutes then 51 beats per minute.

A division is a process of splitting a specific amount into equal parts.

It is given that,

102 beats per 2 minutes

We need to calculate how many beats per minute.

To do this we just have to divide One hundred two by two

102/2

Fifty one beats.

51 beats per minute

Hence 51 beats per minute.

Answer:

-1, 2, 4

Step-by-step explanation:

f(x) is the function's value at any given x.  In other words, it's your function's y coordinate.  You're looking for where the y coordinate is zero - so, in other words, the x intercepts.  Luckily for you, all the x-intercepts here are clearly marked and they were kind enough to give you the coordinates.

Step-by-step explanation:

18 1/6 gallons - 3 7/8 = 14.29

18 - 3 = 15

1/6 - 7/8 = 15 - 0.70833333333 = 14.2916666667

You need to be careful here if you use basic subtraction, simply as two minus would change to addition.
