Answer with explanation:

A number of the form , Z= A + Bi, is called complex number ,where A is real part ,whose Domain is set of real Numbers and B is called Imaginary part,whose Domain is also set of Real numbers.

i= Iota =Square root of (-1).=√-1.

Also,→ a number  of the form ,K i ,is called Imaginary Number.

P= Set of Complex number={3 i, - 5 i, 6 - i, i\sqrt{14}}

Q=Set of Imaginary Number= {3 i, - 5 i, i\sqrt{14}}

→Following are the Set of  complex numbers and Imaginary Numbers, that is ,⇒ P ∩ Q=Common elements of Both P and Q

A: 3 i

B: - 5 i

F: \sqrt{-14}=i\sqrt{14}

Are 25 milligrams lighter or heavier than 25 centigrams
masya89 [10]

Answer:

<em>25 mg. is lighter than 25 cg.</em>

<em />

Step-by-step explanation:

<em>Well,</em>

<em />

<em>The prefix "milli" means thousandth and the prefix "centi" means hundredth.  So a milligram will be one-tenth of a centigram.</em>

<em />

<em>10 mg. = 1 cg.</em>

<em>25 mg. = 2.5 cg.</em>

<em />

<em>2.5 cg. < 25 cg.</em>

<em />

<em>25 mg. is lighter than 25 cg.</em>

How can the function f(x)=x2-6x+8 be rewritten to determine its minimum value?
ki77a [65]

Answer:

Minimum value of f(x) = -1.

Step-by-step explanation:

We convert it to vertex form:

x^2 - 6x + 8

= (x - 3)^2 - 9 + 8

= (x - 3)^2 - 1

The minimum value occurs when (x - 3)^2 = 0  because a square has a minimum value of zero ( it cannot be negative for real values of x).

So  the function has a minimum value of -1.
