8. A computer application generates a sequence of musical notes using the function f(n) 6(16)", where n is the
s2008m [1.1K]

Applying an exponential property, it is found that the function that will generate the same note sequence as function f(n) is given by:

B. H(n) = 6(2)^{4n}

<h3>What is function for the note sequence?</h3>

The function for the node sequence is defined by:

f(n) = 6(16)^n

A function that will the same note sequence as function f(n) has the same initial value of 6. Additionally, applying an exponential property, we have that:

H(n) = 6(2)^{4n} = 6(2^4)^n = 6(16)^n

Hence option B is correct.

Write a proportion that can be used to convert 50 meters into kilometers. Solve the proportion
Levart [38]
So in a kilometer, there is 1,000 meters
so if you have 50 meters you can divide by 1,000 meters like:
50 meters/1 = 1 km/1,000 meters
which should get you 0.05 km

The rate of change of the volume V of water in a tank with respect to time t is directly proportional to the cubed root of the v
Svetllana [295]

Answer:

The differential equation becomes -

\frac{dV}{dt} = k\sqrt[3]{V} i.e. \frac{dV}{dt} = kV^{\frac{1}{3} }

Step-by-step explanation:

Given - The rate of change of the volume V of water in a tank with respect to time t is directly proportional to the cubed root of the volume.

To find - Write a differential equation that describes the relationship.

Proof -

Rate of change of volume V with respect to time t is represented by \frac{dV}{dt}

Now,

Given that,

The rate of change of the volume V of water in a tank with respect to time t is directly proportional to the cubed root of the volume.

⇒\frac{dV}{dt} ∝ \sqrt[3]{V}

Now,

We know that, when we have to remove the Proportionality sign , we just put a constant sign.

Let k be any constant.

So,

The differential equation becomes -

\frac{dV}{dt} = k\sqrt[3]{V} i.e. \frac{dV}{dt} = kV^{\frac{1}{3} }
