Pi/6 is the reference angle for:

Mathematics
1 answer:
Ksju [112]2 years ago
8 0
Option B. 13π/6 and Option D. 5π/6

To get the reference angle π/6 for the given angles we will check each angle given in the options.
A. 8π/6
Since 8π/6 means 240° which lies in 3rd quadrant. Therefore reference angle of 240°= 240-180 = 60° or π/3
B. 13π/6
13π/6 means 390° which lies in first quadrant.
Therefore reference angle = 390-360 = 30° or π/6
C. 3π/6
Since 3π/6 means 90° therefore reference angle of 90° is the same as 90°.
Or the reference angle is = π/2
D. 5π/6
5π/6 means angle is 150° which lies in second quadrant therefore reference angle of 150° = 180-150 = 30° or π/6
answer is Option B and D.

The temperature in degrees Celsius can be determined using the expression 5 9 (F – 32) where F is the temperature in degrees Fah
Norma-Jean [14]

Answer:

The temperature on Celsius scale for 86 ºF is 30 ºC.

Step-by-step explanation:

Both degrees Celsius and Fahrenheit are relative scales of temperature. The relationship between degrees Fahrenheit and degrees Celsius is summarized by the equation below:

T_{C} = \frac{5}{9}\cdot (T_{F}-32) (1)

Where:

T_{F} - Temperature, measured in degrees Fahrenheit.

T_{C} - Temperature, measured in degrees Celsius.

If we know that T_{F} = 86\,^{\circ}F, then its equivalent temperature on Celsius scale is:

T_{C} = \frac{5}{9}\cdot (86-32)

T_{C} = 30\,^{\circ}C

The temperature on Celsius scale for 86 ºF is 30 ºC.

Square ABCD was translated using the rule (x, y) → (x – 4, y + 15) to form A'B'C'D'. What are the coordinates of point D in the
Vitek1552 [10]

Answer:

D = (13, - 23 )

Step-by-step explanation:

Given the translation rule

(x, y ) → (x - 4, y + 15 )

To go in the reverse direction, that is image to original, then, reverse the operations in the translation rule.

(x , y ) → (x + 4, y - 15 ) , thus

D'(9, - 8 ) → D(9 + 4, - 8 - 15 ) → D(13, - 23 )

Outside temperature over a day can be modeled as a sinusoidal function. suppose you know the temperature is 75 degrees at midnig
antoniya [11.8K]

We presume the temperature is decreasing at midnight, so reaches a low at 6 a.m.. The amplitude of the variation is (87-63)/2 = 12 degrees. We want the period to be 24 hours, so the argument of the sine function will be 2π(t/24) = πt/12. Then we can write

... d = 75-12sin(π·t/12)
