Answer: 
Step-by-step explanation:
To find the function h(x), you need to subtract the function
and the function
.

Distribute the negative sign:

Now you can add the like terms:

Therefore, you get that the function h(x) is:

LiftA= u m/s ( upwards)
LiftB= -u m/s(downward)
Velocity A relative to B= V lift A- V lift B=8m/s
u-(-u)=8
u=4m/s
Lift A= 4 m/sec
Lift B= -4m/sec
For someone standing on first floor will be stationary W.r.t to the lift.
V lift A relative to Man= V liftA - V man= 4m/s
V lift B relative to Man= V lift B- V Man= -4 m/s
Answer:
C) Between 9 and 13
Step-by-step explanation:
If 40% is 5 gallons, then 20% is 2.5 gallons
If you multiply both by 5, you get 12.5, which is between 9 and 13
Sorry for my weird way of math
Answer:
17
Step-by-step explanation:
Given

Finding the second term of the sequence means to find
To find
substitute
into the second expression:
3x = 24 - 9
3x = 15
x = 15/3
x = 5
Answer: B) x= 5 or the second option.
