Answer:
it's 0.0045
Step-by-step explanation:
45 times 1 stays 45 just add the zero
So percent means parts out of 100 so
x%=x/100 so
first convert to decimal
so
28 out of 35=28/35
divide completely
0.8
this is over 1 so
0.8/1
make bottom number 100
multiply by 100/100 or 1 so
0.8/1 times 100/100=80/100=80%
the answe ris 80%
Net displacement for a particle in motion with velocity function
v(t)= -3t + 8m/sec from time t =0 to t = 4 is equal to 8units.
As given in the question,
Velocity function of the particle is given by :
v(t)= -3t + 8 m/sec
Particle is in motion from time t = 0 to t =4
Let us consider 's' be the net displacement of the particle
Initial velocity by v(0) at t = 0 is
v(0) = -3(0) + 8
= 8m/sec
Final velocity by v(4) at t= 4
v(4) = -3(4) + 8
= -4m/sec
Total time 't' = 4 - 0
= 4 units
Net displacement :
s = ( 1/2) ( v(4) + v(0) ) t
⇒ s = (1/2)( -4 + 8)(4)
⇒ s = (1/2)(4)(4)
⇒ s = 8 units
Therefore, for the given velocity function and time the net displacement is equal 8 units.
The complete question is :
Determine the net displacement of a particle in motion from t=0 to t=4 given that the velocity function for the particle is v(t)=−3t+8 m/sec. Do not include any units in your answer.

Answer:
C=1 ft
Step-by-step explanation:
c2= a2 + b2 - 2ab
= 8^(2) + 7^(2) - 2(8)(7)
= 113 -112
c2= 1 put a square root on c2 and 1
c = 1
