Mathematics
1 answer:
Sindrei [870]4 years ago
6 0

Answer:

Greatest number = 9867

Smallest number = 1027

Step-by-step explanation:

Greatest number:

- - - 7

In order to form the greatest number, we should simply put the greatest available digit at the thousands place, the second greatest at the hundreds place and the third greatest at the tens place (which would be 9, 8, and 6 respectively).

9867

Smallest number:

- - - 7

In order to form the greatest number, we should simply put the lowest available digit at the thousands place (excluding zero since a number can't start with a zero), put zero at the hundreds place and the third lowest at the tens place (which would be 1, 0, and 2 respectively).

1027

A 429 g piece of cheese costs $9.50. What will be the cost for 1.42 kg of this cheese?

The cost for 1.42 kg of this cheese will be $ 31.44 .

<h3>What does unit conversion entail?</h3>

The process of translating measurements of a given quantity between different units, frequently using multiplicative conversion factors that change the value of the measured quantity without changing its effects, is known as unit conversion. The specific circumstances and the desired result dictate the conversion process. This may be governed by a regulation, contract, set of technical requirements, or other publicly available standards.

<h3>Why is the unitary technique used? What is it?</h3>

In its simplest form, the unitary procedure is used to determine the value of a single unit from a given multiple.

How to calculate the value of one pen, for example, if 40 cost Rs. 400. To finish it, using the unitary method. Additionally, after the value of a single unit has been established, we can multiply that value by the quantity of additional units required to establish the value of the additional units. This is typically how the concepts of ratio and proportion are used. The unitary method entails calculating the value of a single unit before calculating the value of the required number of units.

Given that 0.429 kg of cheese cost $9.50

As a result, the price of 1 kg of cheese is $9.50/0.429, which is $ 22.14.

As a result, 1.42 kg of cheese will cost you $22.14 * 1.42 = $31.44.

Which expression is equivalent to (x^6y^8)^3/x^2y^2?
Masja [62]
For this case we have the following expression:
   (x ^ 6y ^ 8) ^ 3 / x ^ 2y ^ 2
 Rewriting and for power properties we have:
   (x ^ 18y ^ 24) / x ^ 2y ^ 2
   (x ^ (18-2) y ^ (24-2))
   (x ^ 16y ^ 22)
 Answer:
 
The equivalent expression is given by:
   (x ^ 16y ^ 22)

Given that x = 3 + 8i and y = 7 - i, match the equivalent expressions.
drek231 [11]

By applying operations for <em>complex</em> numbers, we have these:

  1. - 5 · x + y = - 8 - i 41
  2. - x · y = - 29 - i 53
  3. x · 2 · y = 58 + i 106
  4. 2 · x - 3 · y = - 15 + i 19

<h3>How to find four equivalent complex expressions</h3>

Herein we must apply the operations of summing two <em>complex</em> numbers, multiplying two <em>complex</em> numbers and multiplying a <em>complex</em> number by a <em>real</em> number, which are defined below:

Addition between two complex numbers

(a + i b) + (c + i d) = (a + c) + i (b + d)     (1)

Multiplication between two complex numbers

(a + i · b) · (c + i d) = (a · c - b · d) + i (b · c + a · d)

Multiplication of a complex number by a real number

k · (a + i b) = k · a + i k · b      (2)

Now we proceed to find the equivalent expressions:

- 5 · x + y = - 5 · (3 + i 8) + (7 - i) = (- 15 - i 40) + (7 - i) = - 8 - i 41

- x · y = - (3 + i 8) · (7 - i) = (- 3 - i 8) · (7 - i) = (- 21 - 8) + i (- 56 + 3) = - 29 - i 53

x · 2 · y = (3 + i 8) · 2 · (7 - i) = (3 + i 8) · (14 - i 2) = (42 + 16) + i (112 - 6) = 58 + i 106

2 · x - 3 · y = 2 · (3 + i 8) - 3 · (7 - i) = (6 + i 16) + (- 21 + i 3) = - 15 + i 19
