The melting point of DNA with 50% GC content = 104 °C

<h3>Further explanation</h3>

DNA has a base pair of bonds between adenine and thymine and guanine and cytosine. These bonds are hydrogen bonds.

Three hydrogen bonds between guanine-cytosine and two hydrogen bonds adenine-thymine make denaturation of DNA by heating it requires greater heat energy.

The amount of guanine and cytosine in the DNA molecule (the GC content) is directly proportional to the melting point, the temperature at which DNA is denatured

If we plot between the melting point of DNA (y-axis) and the percentage of the GC content (x-axis) we will get a straight line equation

From the equation of the line (y = 0.5x + 79), with GC content 50%, we enter the GC value as x so we get the DNA melting point as y

y = 0.5.50 + 79

y = 104 °C

We have the equation of the line as follows:
y = 0.5x + 79

We want to calculate the melting point (the y value) of DNA  with 50% gc content (the x value).
The gc content represents the value of x in the equation, so to calculate the melting point (y), we will simply substitute the x with 50 in the equation of the line as follows:
melting point = 0.5(50) + 79 = 25 + 79 = 104 degrees

anastassius [24]

Answer:

  • 12. x = 6, side = 83
  • 13. x = 18, side = 29
  • 14. x = 11, sides = 74, 74 and 37
  • 15. x = 23, sides = 95, 95 and 108

Step-by-step explanation:

<em>11 is incomplete, can't solve</em>

12

<u>The triangle is equilateral, so all sides are equal, using one pair to find x:</u>

  • 13x + 5 = 17x - 19
  • 17x - 13x = 5 + 19
  • 4x = 24
  • x = 6

<u>Each side is:</u>

  • 13*6 + 5 = 78 + 5 = 83

13.

<u>Sides are equal as triangle is equilateral</u>

  • QR = 2x - 7
  • RS = 5x - 61
  • QS = x + 11

<u>Finding x by comparing two sides</u>

  • 2x - 7 = 5x - 61
  • 5x - 2x = 61 - 7
  • 3x = 54
  • x = 18

<u>Sides are equal</u>

  • 18 + 11 = 29

14.

<u>Equal sides of isosceles triangle:</u>

  • CD = DE
  • 9x - 25 = 6x + 8
  • 9x - 6x = 8 + 25
  • 3x = 33
  • x = 11

<u>Sides are</u>

  • CD = DE = 9*11 - 25 = 99 - 25 = 74
  • CE = 10*11 - 73 = 110 - 73 = 37

15.

<u>Equal sides of isosceles triangle WXY, WX = WY</u>

  • WX = 4x + 3
  • WY = 7x - 66
  • XY = 5x - 7
  • 4x + 3 = 7x - 66
  • 7x - 4x = 3 + 66
  • 3x = 69
  • x = 23

<u>Sides are:</u>

  • WX=WY = 4*23 + 3 = 95
  • XY = 5*23 - 7 = 108

In Death Valley, California, the highest ground temperature recorded was 94°C on July 15, 1972. In the formula C= 5/9 (F - 32) ,
gulaghasi [49]

Answer:

F=201.2\°

Step-by-step explanation:

we know that

\°C=\frac{5}{9}[\°F-32]

For C=94\°

substitute in the formula and solve for F

94=\frac{5}{9}[F-32]

(\frac{9}{5})*94=[F-32]

F=(\frac{9}{5})*94+32

F=201.2\°

Can anybody show me how to do this half angle identity problem STEP BY STEP? I always seem to be missing something
klio [65]

Answer:   \bold{-\dfrac{7\sqrt2}{10}}

<u>Step-by-step explanation:</u>

It is given that θ is between 270° and 360°, which means that θ is located in Quadrant IV ⇒ (x > 0, y < 0).  Furthermore, the half-angle will be between 135° and 180°, which means the half-angle is in Quadrant II ⇒ cos\ \dfrac{\theta}{2}

It is given that sin θ = -\dfrac{7}{25}  ⇒  y = -7 & hyp = 25

Use Pythagorean Theorem to find "x":

x² + y² = hyp²

x² + (-7)² = 25²

x² + 49 = 625

x²         = 576

      x   =  24    

Use the "x" and "hyp" values to find cos θ:

cos\ \theta=\dfrac{x}{hyp}=\dfrac{24}{25}    


Lastly, input cos θ into the half angle formula:

cos\bigg(\dfrac{\theta}{2}\bigg)=\pm \sqrt{\dfrac{1+cos\ \theta}{2}}\\\\\\.\qquad \quad =\pm \sqrt{\dfrac{1+\dfrac{24}{25}}{2}}\\\\\\.\qquad \quad =\pm \sqrt{\dfrac{\dfrac{25}{25}+\dfrac{24}{25}}{2}}\\\\\\.\qquad \quad =\pm \sqrt{\dfrac{\dfrac{49}{25}}{2}}\\\\\\.\qquad \quad =\pm \sqrt{\dfrac{49}{50}}\\\\\\.\qquad \quad =\pm \dfrac{7}{5\sqrt2}}\\\\\\.\qquad \quad =\pm \dfrac{7}{5\sqrt2}}\bigg(\dfrac{\sqrt2}{\sqrt2}\bigg)\\\\\\.\qquad \quad =\pm \dfrac{7\sqrt2}{10}

Reminder: We previously determined that the half-angle will be negative.
