Answer:
your answer is 7 because 9 times 2 = 18 then + 7 = 25
Step-by-step explanation:
Answer:
We have to prove
sin(α+β)-sin(α-β)=2 cos α sin β
We will take the left hand side to prove it equal to right hand side
So,
=sin(α+β)-sin(α-β) Eqn 1
We will use the following identities:
sin(α+β)=sin α cos β+cos α sin β
and
sin(α-β)=sin α cos β-cos α sin β
Putting the identities in eqn 1
=sin(α+β)-sin(α-β)
=[ sin α cos β+cos α sin β ]-[sin α cos β-cos α sin β ]
=sin α cos β+cos α sin β- sinα cos β+cos α sin β
sinα cosβ will be cancelled.
=cos α sin β+ cos α sin β
=2 cos α sin β
Hence,
sin(α+β)-sin(α-β)=2 cos α sin β
Answer:
The answer is 5.
Step-by-step explanation:
-3-(-8) = -3+8 = 5.
Answer:
13%
Step-by-step explanation:
Percentage of tulips=100%-75%
=25%
Percentage of pink tulips=50%×25%
=12.5%
Hence, the option with 13% is closest to 12.5% when it is rounded off to the nearest ten.
Thus, the answer is 13%.
hope it helps!!!
