What is your last question?
Answer:
the turtle is 20 and in 10 years it will be 30
Step-by-step explanation:
Answer:
It is 4x+2
Step-by-step explanation:
In percentage problems, the term rate refers to the actual percentage itself. Let's look at an example. If you have a principal amount of 1000 and you will be getting a yearly interest of 5%, then the rate is the 5%. We refer to it as the interest rate. So if you are looking for the rate in any percentage problem, then you just have to look for the number that has the percentage symbol. The one with the percentage symbol is always the rate.
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.
