Answer:
22.35 m/s
Step-by-step explanation:
The distance is always a positive unit, so distance traveled (d) = 15 miles
Time (t) = 0.3 hours
Time (t) = 0.3 * 60 = 18 minutes
(1 hour = 60 minutes)
Velocity (v) = ?
The formula of distance is: d = v*t
=> v = d/t = 15/18 = 0.83 miles/minute
we can also calculate velocity is meter/sec, for that
1 minute = 60 sec
=> 18 mins = 18*60 = 1080 sec
1 mile = 1609.34 meters
=> 15 miles = 15 * 1609.34 = 24,140 m
hence,
v = 24,140/1080 = 22.35 m/s

Option A is correct.
If we evaluate the function at 
, i.e. at the beginning, we have
with each minute, you multiply the current number of cell by 2, so they double every minute.
Option B is incorrect, because if the number of cells increases by 2 every minute, the function would be
Option C is incorrect, because after one minute (i.e. when x=1) we have
cells, so 75 is not the number of cells after one minute
Option D is incorrect in both the initial value and the behaviour of the function
Answer:
PS = 84.5 , x = 43.75
Step-by-step explanation:
Since RQ is congruent to PS, PS is 2x - 3
SR: 4x + 1
Extra at the bottom: 4
4x + 1 + 4 = 180
4x + 5 = 180
- 5 - 5
4x = 175
/4 /4
x = 43.75
Plug in for PS
2 (43.75) - 3
87.5 - 3
84.5
I hope this helps!
