T^2-t=12
t^2-t-12=0
(t-4)(t+3)=0

42=6x7 then 60=6 x 10 so the least number cover the square should be 6x7x10, that is 420
Answer:
Step-by-step explanation:
Assuming the decay factor, m = 0.0005
f(x) =
f(9000) = = 1 - 0.0111 = 0.99
Answer:
(7/2 , 1/2)
Step-by-step explanation:
(5,-8)=(x1,y1)
(2,9)=(x2,y2)
now,
midpoint(x,y)= x1+x2/2 y1+y2/2
5+2/2 -8+9/2
7/2 1/2
therefore the midpoint of these points is(7/2 , 1/2)
