We use the identity  sin (A - B) = sin A cos B - cos B sin A

so the above  = sin (11pi/12 -  pi/6) = sin 3pi/4 =  1 / sqrt2 answer

Solve the inequality: 3p - 16 < 20
Alekssandra [29.7K]

Isolate the p. First, add 16 to both sides

3p - 16 (+16) < 20 (+16)

3p < 36

Next, isolate the p. Divide 3 from both sides

3p/3 <36/3

p < 12

p < 12 is your answer

hope this helps

Warren measured a rectangular window to find out how much plastic he would need to cover it. The window measured 5 ft 6 inches b
Sedbober [7]

5 feet 6 inches is equal to ((5*12)+6) inches, which is equal to 66 inches since 5*12=60 and 60+6=66

2 feet 9 inches is equal to ((2*12)+9) inches, which is equal to 33 inches since 2*12=24 and 24+9=33

Since 66 and 33 are the length and width (there isn't any specific order as to which measurement is the length or width) and the question is asking for square inches,(which is the area) so what needs to be done next is 66*33, which equals 2178, the square inches of plastic needed is 2718 square inches.

I couldn't keep the answer in the format of _ft _in because they are asking for the area in inches, and I don't think it would be smart to convert inches to decimal values of feet for reasons I won't talk about.

So yeah, your answer is <u><em>2178 square inches of plastic.</em></u>

A population of bears decreases exponentially.
timurjin [86]

Answer:

  0.8

Step-by-step explanation:

The annual factor will be found by dividing any year's population by the population of the year before. The points most easily read from the graph are the populations for years 0 and 1. Then the annual factor is ...

  factor = (year 1 population)/(year 0 population) = 320/400

  factor = 0.8
