Determine two complex numbers, (a+bi) and (c+di), where a and d are irrational numbers and b and c are rational number

Dafna11 [192]

Answer:

The two complex numbers are $\sqrt2 + 5i \text{ and } 6 + \sqrt5i$

Explanation:

We have to form two complex numbers of the form

$a + ib\\c + id$

such that and d are irrational numbers and b and c are rational numbers.

We know that $\sqrt2, \sqrt3$ are irrational numbers.

5 and 6 are rational numbers.

We put

$a = \sqrt2\\b = 5\\c = 6\\d = \sqrt5\\a+ib = \sqrt2 + 5i\\c + id = 6 + \sqrt5i$

Thus, the two complex numbers are: $\sqrt2 + 5i \text{ and } 6 + \sqrt5i$

A graduated cylinder is filled 25.0 mL with water and a piece of granite is placed in the cylinder, displacing the level to 37.2

kvv77 [185]

The volume of the granite piece in Cm³ is 12.2 cm³

calculation

volume of granite = (volume of cylinder after placing granite - volume of cylinder before placing granite

= 37.2 ml - 25.0 ml = 12.2 ml

convert ml to Cm³

that is 1 ml = 1 cm³

12.2 ml = ? cm³

by cross multiplication

=(12.2 ml x 1 cm³) / 1 ml = 12.2 cm³
