Hi, what questions do you have? Are you planning to or currently taking a course, and if so, what course is it?
Speed of the train : distance traveled / time of the travel = 10.1/(0.5)=20.2 mph
<span>sin(2x)= 2sin(x)cos(x)
can you finish the rest or need more help?
sin(6/5) should be the answer
so we have 2 sin(0.6)cos(0.6)
we know its sin (2x) identity
x=0.6
so its sin(2*0.6)</span>
It's both? it's equal to 2/4 and greater than 1/4
31 days to eat 40 cans
6 days to eat x cans
X = 6•40/31= 240/31 is about 7.74 so needs to buy 8 cans to have enough food
