Answer:
B would be your best choice
Step-by-step explanation:
This sin graph doesn't have a phase shift and its vertical displacement (d) is zero, so you don't need to include it in the equation of y = asin[b(x-c)]+d.
35 x 6 = 210
210 + 150 = 360
She will have saved $350
The answer to the question is
12. c
13. d
It is easy after using formula of t<span>he complex numbers
</span>z1= 5(cos25Deg + i sin25Deg)
z2= 2(cos80Deg + isin80Deg)
so z1/z2 =5/2cis(25Deg-80Deg)=5/2cis(-55Deg)
but we know that sin(-55Deg)= - sin(55Deg), and cos(-55Deg)=cos(55Deg),
finally the answer is Z=5/2(cos55Deg-i sin55Deg) (Z=z1/z2)
