What is the cofunction of cos 2pi/ 9
fiasKO [112]

The cofunction of cos is sin(90-x)

90 degrees is equal to PI/2

The cofunction becomes sin(PI/2 - 2PI/9)

Rewrite both fractions to have a common denominator:

PI/2 = 9PI/18

2PI/9 = 4PI/18

Now you have sin(9PI/18 - 4PI/18)

Simplify:

Sin(5PI/18)

Pavel [41]

Answer:

  46 cm

Step-by-step explanation:

Let p represent the length in cm of 1 bap'ai; let k represent the length in cm of 1 bok'ai. Then we have ...

  12p +2k = 100

  10p +10k = 100

Subtracting the second equation from 5 times the first, we get ...

  5(12p +2k) -(10p +10k) = 5(100) -(100)

  50p = 400

  p = 8 . . . . cm

Then the second equation tells us ...

  10(8) +10k = 100

  10k = 20

  k = 2 . . . . cm

Then 5p+3k = 5(8) +3(2) = 46 cm.

The distance 5 bap'ai and 3 bok'ai is 46 cm.

sleet_krkn [62]

Answer:

A

Step-by-step explanation:

I think that's the answer because

60 minutes = 1 hr

120 minutes = 2hrs

So the graph must be constant with the write amount of min/hr since the x axis is the number of mins and the y axis is the number of hours.  (x,y)

(60,1)

(120,2)
