Add up the exponents of i : 0+1+2+3+4 = 10. So we have i^10.

This separates as follows: (i^4)^2 *i^2, which is equal to (1)^2 * (-1) = -1.

<h3><u>Answer:</u></h3>

The answer is:

$|x-50|\leq \dfrac{7}{32}$

$49\dfrac{25}{32}\leq x\leq 50\dfrac{7}{32}$

<h3><u>Step-by-step explanation:</u></h3>

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.

i.e. the absolute change in the width has to be less than or equal to 7/32 in. and it can't exceed more than that.

That is if it will decrease than the the acceptable width for the conveyor belt is represented by the expression;

$|x-50|\leq \dfrac{7}{32}$

Also on solving it we get:

$\dfrac{-7}{32}\leq x-50\leq \dfrac{7}{32}\\\\\\50-\dfrac{7}{2}\leq x\leq 50+\dfrac{7}{2}\\\\49\dfrac{25}{32}\leq x\leq 50\dfrac{7}{32}$

Hence, the correct choices are:

$|x-50|\leq \dfrac{7}{32}$

$49\dfrac{25}{32}\leq x\leq 50\dfrac{7}{32}$
