This product involves zero. So, you don't have to bother and compute all the factor, because if you multiply anything by zero you get zero.
Answer:930
Step-by-step explanation:
Answer:
i think yes it can
Step-by-step explanation:
Answer:
y= -5(x-4)
Step-by-step explanation:
any point slope equation is in form y-y1 = m(x-x1)
plug in the point and constant value
y-0 = -5(x-4)
y= -5(x-4)
Cosx= sin(90-x)
From the RHS,
sin(90-x)= sin90cosx-cos90sinx
Since sin90=1, cos90=0
sin90cosx-cos90sinx=cosx-0=cosx (proven)
