Among all pairs of numbers whose difference is 14 find a pair whose product is as small as possible

zvonat [6]

The pair two numbers whose difference is 14 and the product is as small as possible (i.e. -49) are (-7,7)

<h3>What are word problems?</h3>

In mathematical concepts, word problems involve a crucial understanding of the problem and knowing which mathematical method and arithmetic operations are best suited to solving the problem.

If we assume that the smaller number should be = a and the larger number = a + 14.

Thus, their product (X) can be expressed as:

= a(a+14)

= a² + 14a

The smallest possible value implies the minimum value, i.e.

$\mathbf{\dfrac{dX}{da} = 2a + 14}$

Thus,

2a + 14 = 0

a = - 14/2

a = -7

Therefore, we can conclude that the pair of two numbers whose difference is 14 and the product is as small as possible (i.e. -49) is (-7,7).

Assuming ideal solution behavior, how many liters of hcl gas, measured at 30. 0 °c and 745 torr, are required to prepare 1. 25 l

Nostrana [21]

The volume of HCl gas required to prepare the solution is 101.54 L

<h3>How to determine the mole of HCl </h3>

Volume of solution = 1.25 L
Molarity = 3.20 M
Mole of HCl =?

Mole = Molarity x Volume

Mole of HCl = 3.2 × 1.25

Mole of HCl = 4 moles

<h3>How to determine the volume of HCl </h3>

Number of mole (n) = 4 moles
Temperature (T) = 30 °C = 30 + 273 = 303 K
Pressure (P) = 745 torr = 745 / 760 = 0.98 atm
Gas constant (R) = 0.0821 atm.L/Kmol

Volume =?

Using the ideal gas equation, the volume of the HCl gas can be obtained as follow:

PV = nRT

Divide both side by P

V = nRT / P

V = (4 × 0.0821 × 303) / 0.98

V = 101.54 L

Neuroleptics are drugs that help the brain process which of the following

Alika [10]

Neuroleptics are type of drugs that help the brain in processing the following: B. Dopamine.

A drug can be defined as a type of chemical substance that is designed and developed to improve and provide wellness and healing to a sick person.

<h3>What is a brain?</h3>

A brain can be defined as a delicate internal organ of soft-nerve tissue that is primarily found within the skull of vertebrates, and it's mainly responsible for the coordination of nervous activities, sensation and intellect in living organisms.

Based on medical records and information, we can infer and logically deduce that neuroleptics are type of drugs that help the brain in processing dopamine levels in a living organisms, so as to enable them:

Move

Memorize

Have pleasurable reward.

Be motivated.
