Π/12 is half of π/6, which is 30 degree
tan(α/2)=(1-cosα)/sinα)
plug in the values: tan(π/12)=(1-cosπ/6)/sin(π/6)=(1-√3/2)/(1/2)=2-√3
The answer must be - cospi/2 which is not available in the option
Answer:
0.001189 x 10^7
Step-by-step explanation:
4.1 x 10^7 gallons of water
2,900 gallons of water = 2.9 x 10^3
Balance the 10th power with the first one.
2,900 = 0.00029 x 10^7
Multiply only the decimal number...
4.1 x 0.00029 = 0.001189
The answer is...
0.001189 x 10^7
10≤n<100
So the number of two digit numbers is 99-10+1=90
The only combinations that sum to 5 are 14, 23, 32, 41, 50 so
P(sum=5)=5/90
P(sum=5)=1/18
8, because you’re doubling the numbers so 3x2=6 and 4x2=8.
