2. Describe how to use the conjugate to divide 2 − i by 3 + 2i, and then find the quotient.
DaniilM [7]

Answer:

\frac{4}{13}-\frac{7}{13}i

Step-by-step explanation:

\frac{2-i}{3+2i}

Multiply and divide by the conjugate.

The conjugate is the denominator with the sign of the complex number the opposite of the denominator.

\frac{2-i}{3+2i}\frac{3-2i}{3-2i}\\ =\frac{2\times (3-2i)-i\times (3-2i)}{3^2-(2i)^2}\\ =\frac{6-4i-3i+2i^2}{9+4}\\ =\frac{4-7i}{13}\\ =\frac{4}{13}-\frac{7}{13}i

Quotient = \frac{4}{13}-\frac{7}{13}i

Help please this is due today!!!<br><br> please provide a small explanation!!
AlekseyPX

Answer:

200 sq cm

Step-by-step explanation:

Lateral surface area is the surface area without the bases, or without the top and bottom. So, you just add up the area of the 4 sides.

The front and back are both 10 x 20, so 200 each = 400

The left and right are 5 x 20, so 100 each = 200

The lateral surface area is 200 sq. cm.

Helooooo?!!!!! 30 whole points
pentagon [3]

Answer:

I believe C, or the answer you have chosen, is correct.

Step-by-step explanation:

In this question, we add like, AKA similar, terms.

There is nothing to match x^2, so we leave it alone and put it at the head of equation since it has the highest power:

x^2

There is nothing to match -x, so we also leave it alone and put it next to x^2, keeping its sign:

x^2 - x

We can add 1 and 5 to get 6, so we put 6 next to the -x to get our final equation:

x^2 - x + 6.

See how easy that was? :) Hope this helps you and you get a good grade on your test!!

Please rate my answer and give me Brainliest!!!!

Have an awesome rest of your day! :)

Which of the following is a solution to the differential equation xy′−3y=6 ?
ololo11 [35]

Answer:

y = 5 {x}^{3}  - 2

Step-by-step explanation:

The given differential equation is :

xy′−3y=6

We want to determine which of the following options is a solution to the differential equations.

The function that satisfies the differential equation is a solution.

We can verify that

y = 5 {x}^{3}  - 2

satisfy this differential equation.

We differentiate to get:

y' = 15 {x}^{2}

We substitute the function and its derivative into the differential equation to get:

x(15 {x}^{2}) - 3(5 {x}^{3}   - 2) = 6

We expand and simplify on the left:

15 {x}^{3}- 15 {x}^{3}   + 6= 6

This simplifies to:

6 = 6

Verified.

We can show that all the other functions do not satisfy this differential equation

18x26=? I don't get how to do this
elena-s [515]

Answer:

468

Step-by-step explanation:

Set it up like the following-

18

26

--------

108

360

--------

408

Take the right number (6) and multiply it with 18

6 x 18 = 108

Now do the same with 2, except put a 0 at the end

2 x 18 = 36

add 0

360

Add both numbers-

360 + 108 = 468
