Answer:
C.y=sin(x-2)
Step-by-step explanation:
Using the topic of transformation of functions(rules shown in picture above)
the the (x-2) moves the graph to places to the right
and as the sine graph goes through 0 and so you add 2 to the right (but there is a problem in the graph should in the picture as it should me labeled 0,90,180,270,360 not these small numbers)
hope it helps!! :)
D. the upper quartile contains more values than the lower quartile.
You look for two good points on the graph, then you rise and run.( go up then move right or left)
1/2p=p (1-0.2)^t
1/2=(1-0.2)^t
1/2=(0.8)^t
Log (1/2)=t×log (0.8)
T=log(1÷2)÷log(0.8)
T=3.1 years
