Answer:
Step-by-step explanation:
Identities : -
cot = cos / sin
tan = sin / cos
( cot + tan ) sin = sec
LHS
= ( cot + tan ) sin
= ( ( cos / sin ) + ( sin / cos ) ) sin
= ( ( cos sin ) / sin ) + ( sin² / cos )
= cos + ( sin² / cos )
LCM = cos
= ( cos² / cos ) + ( sin² / cos )
= ( cos² + sin² ) / cos
Identity : -
cos² + sin² = 1
= 1 / cos
= sec
= RHS
Hence proved.
Answer: 6.24 tablespoons
Explanation: okay so if $.39 is 2 tablespoons, then you can multiply that by 8 because there are 8 tablespoons in half a cup. After you multiply that just multiply it by 2 because they are trying to make two pies. And that’s how you your answer.
I think it might be -38, not 100% though.
