I believe the answer is A because you cannot find x nor y
Answer:
-13-9a
Step-by-step explanation:
Answer:
Step-by-step explanation:
the displacement of the particle is given by

The rate of change of position gives the value of velocity.
So, v = ds/dt
Differentiate the position function with respect to time.

Now, at t = a
v = -18/a³ m/s
At t = 1
v = - 18 m/s
At t = 2
v = - 18 / 8 = - 2.25 m/s
At t = 3
v = - 18 / 27 = 0.67 m/s
Answer:
t=11.9
Step-by-step explanation:
960=420(2)^t/10
2.28571429=2^t/10
add log to both sides
log(2.28571429)=10
t log(2)
divide by log 2
1.19264508= 10
/t
10(1.19264508)
11.926450779=t
It would be 600 miles in 24 hours if it continues to fly at the same speed cause every 2 hours the distance goes up by 50.
