storchak [24]

Answer:

Cos \ 300 = \dfrac{1}{2}

Step-by-step explanation:

  \sf \boxed{Cos \ (2\pi - \theta) = Cos \ \theta}

Cos 300 = Cos ( 360 - 60)

               = Cos 60

Which equation represents the line that passes through points (1, –5) and (3, –17)? y = negative 6 x + 1 y = 6 x + 1 y = negativ
Paraphin [41]

Answer:

Using y = mx + c

slope = -17+5/3-1 = -12/2 = -6

Using point (1 , - 5)

y + 5 = -6(x - 1)

y + 5 = - 6x + 6

y = - 6x + 6 - 5

y = - 6x + 1

Hope this helps.

arlik [135]

Answer:a. [tex] $f\propto  L$ [\tex]

b. [tex] f \propto \sqrt{T} [\tex]

c. [tex] f \propto \frac{1}{\sqrt{P}} [\tex]

I. Decrease in length increases leads to increase in pitch.

II. Increase in tension leads to increase in pitch.

III. Increase in linear density reduces the pitch

Step-by-step explanation: I. Since the frequency is inversely proportional to the length increase in length leads to decrease in frequency likewise decrease in length leads to increase in frequency.

II. Since the frequency is directly proportional to the square root of the tension increase in tension leads to increase in frequency likewise decrease in tension leads to decrease in frequency.

III.since the frequency is inversely proportional to the square root of the linear density so increase in linear density leads to decrease in frequency and likewise decrease in linear density leads to increase in frequency.
