The half angle formula is:
sin x/2 = +/- √ (( 1-cos x ) / 2 )
5π/12 = 5π/6 : 2
sin 5π/12 = +/- √(( 1 - cos ( 5π/6)) / 2 )
cos 5π/6 = cos 150° = -√3/2
≈ 0.966 ( this is sin 5π/12 )
Answer:
225 square cm
Step-by-step explanation:
Answer:
0.9506
Step-by-step explanation:
Pr(A) = 0.02
Pr(B) = 0.03
Pr(both) = 0.007
So,
Pr(Not A) = 1 - Pr(A)
= 1 - 0.02
= 0.98
Pr(Not B) = 1 - Pr(B)
= 1 - 0.03
= 0.97
Pr(Not by both) = 1 - Pr(both)
= 1 - 0.007
= 0.993
Thus,
Pr(Not B) or Pr(Not A) = 0.97 × 0.98
= 0.9056
∴ the probability that the house would not be damaged by a hurricane or an earthquake during the year is 0.9506.
Answer:
6(9r-7)
Step-by-step explanation:
54r–42
Both 54 and 43 can be divided by 6
54/6 =9 and 42/6 =7
6*9r - 6*7
Factor out the 6
6(9r-7)
One way to check if 102 ÷ 6 = 17 is by focusing on the left side of the equation.
102 ÷ 6 can be converted into 
can be simplified, lets start by dividing the numerator and denominator by 2.
\frac{102/2}{6/2} = \frac{51}{3}
= 
can be rewritten as 17.
