2. Write an expression to represent f (20)

Mathematics
1 answer:
Furkat [3]3 years ago
7 0

Answer:

I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).

Step-by-step explanation:

So, my answer was f(20) = 64(1/2)^19

f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.

Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19

I hope this helps!

KonstantinChe [14]

Answer:

  V = πr²h

Step-by-step explanation:

The formula for the volume of a cylinder is ...

  V = πr²h

where V is the volume, r is the radius, and h is the height of the cylinder.

_____

<em>Comment on the formula</em>

This is a specific version of the formula for any sort of "prism" with parallel bases and a uniform cross section (parallel to the bases). The volume of such a figure is computed as ...

  V = Bh

where B is the area of the base and h is the perpendicular distance between the parallel bases. Here, the base is a circle, so has area formula ...

  B = πr²

Filling this into the volume formula gives ...

  V = πr²h . . . . . as above
