Mathematics
1 answer:
Stells [14]2 years ago

Answer:

3(2v - 3)(3v + 2)

Step-by-step explanation:

18v² - 15v - 18 ← factor out 3 from each term

= 3(6v² - 5v - 6) ← factor the quadratic

consider the factors of the product of the coefficient of the v² term and the constant term which sum to give the coefficient of the v- term.

product = 6 × - 6 = - 36 and sum = - 5

the factors are - 9 and + 4

use these factors to split the v- term

6v² - 9v + 4v - 6 ( factor the first/second and third/fourth terms )

= 3v(2v - 3) + 2(2v - 3) ← factor out (2v - 3) from each term

= (2v - 3)(3v + 2)

Then

18v² - 15v - 18 = 3(2v - 3)(3v + 2)

Given z=4+3i evaluate z​
DerKrebs [107]

Answer:

5

Step-by-step explanation:

Assuming we want to evaluate |z|, given that, z=4+3i.

Then, by definition of modulus,

|x + yi|  =  \sqrt{ {x}^{2} +  {y}^{2}  }

|4+ 3i|  =  \sqrt{ {4}^{2} +  {3}^{2}  }

|4+ 3i|  =  \sqrt{ 16+  9 }  \\ |4+ 3i|  =  \sqrt{25 }  \\ |4+ 3i|  = 5

Therefore the modulus be of the given complex number is 5 units

Finding a parametric description of the solution set of a linear system is the same as solving the system.Choose the correct ans
Grace [21]

Answer:

The answer is "Choice B".

Step-by-step explanation:

Please find the complete question in the attached file.

In this question, in all choices, the choice (B) is Correct because in the declaration of the statement Only when the process has had at least another answer could a candidate solution for more than just a linear model explicitly uses a parametric description that's why the given statement is true.

Pease help, thank you
andreyandreev [35.5K]

Answer: -2

=====================================================

Draw a vertical line through 4 on the x axis. This vertical line crosses the parabola at some point (which we'll call point A). Draw a horizontal line from point A to the y axis and note how it lands on y = 12. Therefore the point (4,12) is on this parabola.

Repeat the same steps as before to find that (8,4) is also on the parabola

We need to find the slope of the line through (4,12) and (8,4)

m = (y2 - y1)/(x2 - x1)

m = (4-12)/(8 - 4)

m = -8/4

m = -2

The slope of this line is -2 meaning that the average rate of change from x = 4 to x = 8 is -2.

The line goes down 2 units each time you move to the right 1 unit.

What is the simplified form of the following expression? <br><br> ^3sqrt(4x/5)
Vladimir [108]

Answer:

= (∛(100x))/5

Step-by-step explanation:

Given the expression; ∛(4x/5)

To simplify this we need to make denominator a perfect cube.

So multiply and divide 25 inside the cube root, so that the denominator will become a perfect cube of 5.

∛(4x/5) = ∛((4x/5)×(25/25))

            = ∛(100x/125)

            = ∛(100x/5³)

            <u>= (∛100x)/5</u>
