Which expression represents the number + + + rewritten in a+bi form?

me out!

which is the answer?

−3+2i
5+0i
5−2i
−3−4i
−3+0i

Step-by-step explanation:

Recall the following identities:

i^4 = 1

i³ = -i

i² = -1

i = 1

Thus, the first term, 5i^4, is equivalent to 5.

The second term, 2i³, is equivalent to -2i.

The third term, 8ix², is equivalent to 8ix².

The fourth term, √(-4), is equivalent to 2i.

Combining these four results, we get:

5 - 2i + 8ix² + 2i

-2i and 2i cancel out, leaving     5 + 8ix²

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
