Given a system of linear equations: dy/dx = 4x-y dy/dx = x-2y Find the general solution.

Mathematics

mina [271]3 years ago
3 0

Answer:

x=-y/3

y=-3x

Step-by-step explanation:

dy/dx=4x-y means 4x-y=0

dy/dx=x-2y also means x-2y=0 then

4x-y=x-2y

3x=-y

y=-3x

x=-y/3

. Five plus a number divided by 2 is 9.
Tresset [83]

Answer:

Using a calculator, if you typed in 9 divided by 2, you'd get 4.5. You could also express 9/2 as a mixed fraction: 4 1/2.

Pls answer the question 12 points I will mark brainliest
vladimir2022 [97]

Answer:

should be 66.4

Step-by-step explanation:

<u>triangular prism:</u>

Using the formulas

AB=s(s﹣a)(s﹣b)(s﹣c)

V=ABh

s=a+b+c

2

Solving forV

V=1

4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=1

4·3·﹣24+2·(2·2)2+2·(2·2)2﹣24+2·(2·2)2﹣24≈5.19615

5.2 · 2 = 10.4

<u>Rectangular prism:</u>

<u>V=whl=2·2·14=56</u>

<u />

<u>10.4+56=66.4</u>

Use the given information to write the equation of the parabola.
m_a_m_a [10]

Answer:

x² = -2y

Step-by-step explanation:

The focus is p away from the vertex, and so is the directrix.

To find the equation of the parabola, we must first determine if the parabola is horizontal or vertical.

  • Horizontal parabola [Standard form]: (y – k)² = 4p(x – h)
  • Vertical parabola [Standard form]: (x – h)² = 4p(y – k)

If the parabola is vertical, the directrix, and focus will have the same x value but different y value compared to the vertex (h, k). You can also tell if the directrix in in the form y = k – p, and if the focus is in the form (h, k + p).

Likewise, if the parabola is horizontal, the directrix, and focus will have the same y value but different x value compared to the vertex (h,k) . You can also tell if the directrix is in the form x = h – p, and if the focus is in the form (h + p, k).

For this problem, given that the vertex is at the origin (0,0), and that the focus is at the point (0, -½).

You can tell that the x value is the same for the vertex, and focus so this must be a vertical parabola. Because this is a vertical parabola, we can use the form mentioned as earlier (x – h)² = 4p(y – k).

If h = 0, and k = 0, the p value must be the difference between the k of the vertex, and the k of the focus: -½ - 0 → -½.

Now we can just plug in our known information to derive the equation!

h = 0, k = 0, p = -½ → (x - h)² = 4p(y - k) →

(x - 0)² = 4(-½)(y - 0) → x² = -2(y - 0) →

x² = -2y.

Also p = 1/4a, if you are wondering.

So because this is a vertical parabola, x² = -2y is generally the same as y = -1/2x² in standard quadratic form. I just like to think of the horizontal parabola as an inverse quadratic because it is like reflecting over the line y = x.
