Answer:
Rational
Step-by-step explanation:
The square root of 25 is 5, which is a rational number.
Well when she hits the water h=0 so
2t^2-t-6=0 factor
2t^2-4t+3t-6=0
2t(t-2)+3(t-2)=0
(2t+3)(t-2)=0, since t>0
t=2 seconds...
However it should be noted that h(t)=-2t^2+t+6 implies that
v(t)=dh/dt=-4t+1 and
a(t)=dv/dt=-4
Since this is a free fall equation, this would suggest that the acceleration due to gravity is -4, whether that is supposed to be -4ft/s^2 or -4m/s^2, it certainly is not on this planet! :D If it is -4ft/s^2 it could be on the Moon or if it is -4m/s^2 it could be on Mars.
Answer:
-6 and -5 (There are many more combinations of numbers that can equal to -11 but this is just one of the many possibilities.
Step-by-step explanation:
-6 and -5
See you can write it like this,
-6+ (-5)
= -6-5
=-11
