Answer:
150 seconds
Step-by-step explanation:
use the velocity equation of
Where V is in feet per second, Delta D represents the change in displacement and delta t represents the change in time
all you need to do is rearrange the equation to find Delta(T)
as such...
635 (635.0293 not rounded)
C
If x is the average (arithmetic mean) of m and 9, y is the average of 2m and 15, and z is the average of 3m and 18,
x=(m+9)/2
y=(2m+15)/2
z=(3m+18)/2
the average of x, y, and z
=(x+y+z)/3
=(m+9+2m+15+3m+18)/3
=(6m+42)/3
=2m+14
ans is C
a. 45 degrees
b. 315 degrees
c. 8π
d. π
e. 7π
f. 16π
g. 2π
