PLEASE HELP (PRE ALGEBRA)

Mathematics
1 answer:
densk [106]3 years ago
3 0

Answer: r = 4

Step-by-step explanation:

V = pi * r^2 * h

144 * pi = pi * r^2 * 9

Divide by pi

144 = r^2 * 9

Divide by 9

16 = r^2

Take square root of both sides

rad(16) = rad(r^2)

4 = r

r = 4

If f(1) = 160 and f(n + 1) = –2f(n), what is f(4)?
lions [1.4K]

Answer:

-1280

Step-by-step explanation:

There are 2 ways you could do this. You could just do the question until you come to the end of f(4). That is likely the simplest way to do it.

f(1) = 160

f(2) = - 2 * f(1)

f(2) = -2*160

f(2) = -320

f(3) = -2 * f(2)

f(3) = -2 * - 320

f(3) = 640

f(4) = - 2 * f(3)

f(4) = - 2 * 640

f(4) = - 1280

I don't know that you could do this explicitly with any real confidence.
