Answer:
15 km?
Step-by-step explanation:
10 km per hour for one hour is 10km. plus the half hour, half of the distance 5km is just 15km
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.
