Answer:
O There is a change in the period of the function
Step-by-step explanation:
O There is a change in the period of the function; The period of sin x is 8 times longer than the period of sin 8x.
d =sqrt ((x2-x1)^2 +(y2-y1)^2)
sqrt((12-2)^2 +(7--3)^2)
sqrt(10^2+10^2)
sqt(100+100)
sqrt(200)
sqrt(100)sqrt(2)
10sqrt(2)
Choice B
Basically, the unit rate is 1.99/18 or 0.110.
If we round 1.99 to 2.00, we instead get 0.111~
