What is the 4th term in the sequence b(n)=1(-2)^n-1

Mathematics

marishachu [46]3 years ago
7 0

Answer:

<h2>The answer is 8</h2>

Step-by-step explanation:

From the question the formula for the sequence is

b(n) = 1 ({ - 2})^{n - 1}

where

n is the nth term in the sequence

Since we are finding the 4th term n = 4

Substitute this value of n into the above formula

That's

b(4) = 1 ({ - 2})^{4 - 1} \\  = 1 ({ - 2})^{3}  \\  =   { - 2}^{3}

We have the final answer as

<h3>8</h3>

Hope this helps you

Liono4ka [1.6K]

Answer:

  yes

Step-by-step explanation:

The height that would be allowed with a ramp 43.5 feet long is ...

  h = (43.5 ft)·sin(4.8°) ≈ 3.64 ft

The proposed height is less than 3.64 ft, so the ramp angle is less than 4.8°.

__

The ramp angle is actually arcsin(3/43.5) ≈ 3.95°, which is less than 4.8°.
