Answer:
Cost y is directly proportional to the pound of potato y = 1.89x The constant of proportionality is the cost of 1 pound of potato, and it is 1.89
Step-by-step explanation:
I think it is A. not sure though
Answer:
y= -20
Step-by-step explanation:
Remember this: for a trig function of <span>y = A sin(Bx + C) + D
</span><span><span>amplitude is A
</span><span>period is <span>2π/B
</span></span><span>phase shift is −C/B
</span><span>vertical shift is <span>D
So the amplitude is -4, the period is </span></span></span>π and the phase shift is -3.14/2 = 1.57.
