Which choice is the explicit formula for the following geometric sequence?0.5, -0.1, 0.02, -0.004, 0.0008, ...

Answers

The explicit formula for the given Geometric sequence is

$a_(n)= 0.5 * (-0.2)^((n-1))$

The given sequence is a Geometric sequence with the first term,

a = 0.5 and the common ratio, r = -0.2.

We are supposed to find the explicit formula for this sequence.

The general formula for a Geometric sequence is given by

$a_(n)= ar^((n-1))$

where a is the first term, r is the common ratio, and n is the nth term of the sequence.

Substituting a, r and n in the above formula, we get the nth term of the sequence.

Therefore, the explicit formula for the given Geometric sequence is:

$a_(n)= 0.5 * (-0.2)^((n-1))$ .

The explicit formula for the given Geometric sequence is

$a_(n)= 0.5 * (-0.2)^((n-1))$ .

The ideal width of a certain conveyor belt for a manufacturing plant is 50 in. Conveyor belts can vary from the ideal width by at most 7/32 in.

Answers

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

If the ideal is 50 and the max variation is 7/32in, then that's 7/32 under 50 and 7/32 over 50.
So, 50-7/32= 49 25/32, and 50+7/32 = 50 7/32.
So the acceptable width is 49 25/32 to 50 7/32.

Answer;

The acceptable width is 49 25/32 and 50 7/32

That is; 49 25/32 ≤ x ≥ 50 7/32

Explanation;

-If the ideal is 50 and the max variation is 7/32 inches, then that's 7/32 under 50 and 7/32 over 50.

Therefore; 50-7/32= 49 25/32, and 50+7/32 = 50 7/32.

x ≤ 50 7/32 and x ≥ 49 25/32

Thus; the acceptable width is 49 25/32 ≤ x ≥ 50 7/32.
