sea level is 0 and a deck is above water, so 10 and below sea level is where people scuba dive, so the dot at -15
C, the third choice, 8 to the third power (8^3) :)
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:
pretty sure its store b Step-by-step explanation:
because 15 percent of 75 is 11.25 and that means you're going to pay 63.75, but store b you only pay 60. Store c you buy it full price but your getting 15 dollars rebate only after you purchase it, and its thru mail so its better to pay just the 60
Your answer would be yes u can
