Answer:
the answer is 140 , please let me know if I am wrong.
0.3 because it’s less than 5
In 1 hour you pick 60 lines, so in 8 hours you pick 60*8 = 480 lines
Ok, so we see in
y=a(x-h)^2+k
vertex is (h,k)
vertex is highest or lowest point
on one side, it goes up and other side it goes down
if a is positive, then it goes down then up
if a is negative, it goes up then down
we see
f(x)=2(x+3)^2+2
2 is positive
goes down then up
vertex is (-3,2)
so decreases from -infinity to -3 or ininterval
(-infinity,-3)
answer is first option
