Write a recursive formula for a n a n , the n th n th term of the sequence 6 , − 12 , 24 , . . .
Anton [14]

Answer:

See below ↓↓

Step-by-step explanation:

a₁ refers to the first term of the sequence.

That is clearly : a₁ = <u>6</u>

<u></u>

The formula for the nth term is :

  • aₙ = a₁rⁿ⁻¹
  • Common ratio (r) = quotient of consecutive terms
  • r = -12/6 = -2

Therefore, the nth term is :

  • aₙ = <u>6(-2)ⁿ⁻¹</u>

The radius r of a sphere is increasing at a constant rate of 0.04 centimeters per second. (Note: The volume of a sphere with rad
-Dominant- [34]

Answer:

The rate of the volume increase will be \frac{dV}{dt}=50.27 cm^{3}/s

Step-by-step explanation:

Let's take the derivative with respect to time on each side of the volume equation.

\frac{dV}{dt}=4\pi R^{2}\frac{dR}{dt}

Now, we just need to put all the values on the rate equation.

We know that:

dR/dt is 0.04 cm/s  

And we need to know what is dV/dt when R = 10 cm.

Therefore using the equation of the volume rate:

\frac{dV}{dt}=4\pi 10^{2}0.04

\frac{dV}{dt}=50.27 cm^{3}/s

I hope it helps you!
