Step-by-step explanation:
The displacement of a particle d (in km) as a function of time t (in hours) is given by :

Displacement at t = 4 hours,

Velocity of particle is given by :

Velocity at t = 4 hours,

Acceleration of the particle is given by :

At t = 4 hours,

Therefore, the displacement, velocity and acceleration at t = 4 hours is 205 km, 136 km/h and 58 km/h² respectively.
Answer:
25 boxes because if you divide 590 from 23.25 it equals 25. I got 590 by subtracting 650 and 60 to make sure there is still that remaining 60 in the supply account.

Answer:
missing value b is 14
Step-by-step explanation:
We have been given the modulus of a complex number which is

Here on comparing the given complex number with general a+bi we get:
a=48 and b=b
On substituting the values in the formula for modulus we get:






Therefore, missing value b is 14
