Answer:
the answer is A
Step-by-step explanation:
Answer:
i think its 0
Step-by-step explanation:
Cos( A + B ) = cosAcosB - sinAsinB ;
cos( A + B ) / ( cosAsinB ) = ( cosAcosB - sinAsinB ) / ( cosAsinB ) = ( cosAcosB ) / ( cosAsinB ) - ( sinAsinB ) / ( cosAsinB ) = cosB / sinB - sinA / cosA = cotB - tanA ;
Answer:
18,432 Km/ h
Step-by-step explanation:
Using the conversions
• 1 Km = 1000 m
• 1 hour = 60 × 60 = 3600 seconds
Then
5120 m =
= 5.12 Km and
5.12 Km × 3600 = 18,432 Km / hour
It is y=1/2x-5
Aka C
Just plug it into piont slope form....and then simplify
