Omar spent 600 dollars for earning 1800 reward points.

<em><u>Explanation</u></em>

Omar earns 300 reward points for every 100 dollars he spends.

Suppose, he spent  x dollar for 1800 reward points.

Now <u>according to the ratio of "amount of money spent" and "reward points"</u> , the equation will be......

\frac{x}{1800}=\frac{100}{300}\\ \\ 300x=180000\\ \\ x=\frac{180000}{300}=600

Thus, Omar spent 600 dollars for earning 1800 reward points.

Which expression is equivalent to i 233?<br> a)1<br> b)–1<br> c)i<br> d)–i
Aneli [31]

We have to find the value of the expression i^{233}

We know that the below values.

i^2=-1\\i^4=1

Hence, in order to find the value of the given expression, we can first rewrite it in terms of i^4

i^{233}=(i^4)^{58}\cdot i

Now, we know that i^4=1

Hence, we have

i^{233}=(1)^{58}\cdot i

i^{233}=1\cdot i

i^{233}=i

C is the correct option.
