A. This question asks us to solve the equation for P. This also means to isolate this variable.
S=Ph+2B
S-2B = Ph
(S-2B)/h = P

B. Using the information, we plug this into the perimeter equation, where h = 4, S=96 and B = 8
(96-2(8))/4 = P
80/4 = P
P = 20 meters²

Show that an implicit solution of 2x sin2(y) dx - (x2 + 11) cos(y) dy = 0 is given by ln(x2 + 11) + csc(y) = C.
Dvinal [7]

Answer:

From the question we are told that

  The  equation is  2x sin^2(y) dx - (x^2 + 11) cos(y) dy = 0

Generally the goal of this solution is to prove that the implicit solution of the differential  equation above is  ln(x^2 + 11) + csc(y) = C.

First Step  

    Differentiate the solution with respect to  x  

   0  = \frac{2x}{ x^2 + 11}  + [-cot * csc(y) ]\frac{dy}{dx}

=> 0 =  \frac{2x}{ x^2 + 11}  + [-\frac{cos(y)}{ sin(y) }* \frac{1}{sin(y)}  ]\frac{dy}{dx}  

=>  0  =  \frac{2x}{ x^2 + 11}  + [-\frac{cos(y)}{ sin^2(y) }]\frac{dy}{dx}

=>  

multiply through by  sin^2(y) , x^2 + 11, dx

So

=> 2 x (sin^2(y) dx  + [-cos(y) (x^2 + 11)]dy = 0

Looking at the equation obtained we see that it is equivalent to the differential  equation hence  the implicit solution of 2x sin^2(y) dx - (x^2 + 11) cos(y) dy = 0 is   ln(x^2 + 11) + csc(y) = C.

Can someone help me ASAP!!!
dimaraw [331]

Answer:

Slope= -7

Step-by-step explanation:

I like to use the rise/run method.

Take the point at (1,-2) and count up to (1, 7). Then because it is going left, you count your run over 3 points. Or you could do.

\frac{y2-y1}{x2-x1} = slope

PLEASE HELP i need this for today at 4
andrew11 [14]

Step-by-step explanation:

Work out the value of x.

<h3>#12</h3>

<u>The angles are supplementary as same side interior angles, sum to 180°:</u>

  • x + x - 26 = 180
  • 2x = 206
  • x = 103
<h3>#13</h3>

<u>The angles are corresponding, hence congruent:</u>

  • 3x - 5 = x + 55
  • 3x - x = 55 + 5
  • 2x = 60
  • x = 30
<h3>#14</h3>

<u>The angles are supplementary as same side interior angles, sum to 180°:</u>

  • 2x + 24 + x = 180
  • 3x = 180 - 24
  • 3x = 156
  • x = 52
<h3>#15</h3>

<u>The angles are corresponding, hence congruent:</u>

  • 4x - 12 = 3x + 6
  • 4x - 3x = 6 + 12
  • x = 18
<h3>#16</h3>

<u>Corresponding with the right angle:</u>

  • 4x + 12 = 90
  • 4x = 78
  • x = 19.5
<h3>#17</h3>

<u>Vertical angle of the bottom angle is supplementary with the top angle:</u>

  • 2x + 12 + 3x + 23 = 180
  • 5x + 35 = 180
  • 5x = 145
  • x = 49
