Answer:

The instantaneous velocity at t = 2 is -6.

Step-by-step explanation:

We have the position as the function

s(t) = -2 - 6t

As we know that the velocity is the rate of change of position over time, so it is basically the derivative of the function.

so finding the derivate of  s(t) = -2 - 6t

∴ s'(t)=-6

The instantaneous velocity at t = 2

s'(2)=-6

Therefore, the instantaneous velocity at t = 2 is -6.

Please note that the negative value indicates the direction of movement, in this case, it would be backward.

If a bank account doubles in size every 5 years, then by what percent does it grow after only 3 years? Round to the nearest tent
mr Goodwill [35]

Answer:

Step-by-step explanation:

Alright, let get started.

Suppose the initial deposit in account = x

After five years, this accounts get doubled means  = 2x

Means in 5 years , the growth = 2x-x = x

So, in 1 year, the growth will be = \frac{x}{5}

So, in 3 years, the growth will be = \frac{x}{5}*3=\frac{3x}{5}

So percent grwoth will be = \frac{\frac{3x}{5}}{x}*100 = 60

Hence percentage growth is 60 %.    :  Answer

Hope it will help :)
