The vector -u will be in the opposite direction of u. The magnitude is 7.81, but the angle is 129.81° -180° = -50.19°. A graph of it is attached.

_____

The (x, y) components are ...

  7.81(cos(-50.19°), sin(-50.19°)) ≈ (-5.00, -6.00)

Analyze the following categorical proposition by doing the following: (1) Identify the subject and predicate of each proposition
spayn [35]

Answer:

(1) Subject term: Bats and Predicate term: Mammals.

(2) A- Proposition

Step-by-step explanation:

Categorical proposition is a tool of deductive reasoning that involves two classes of objects. Coined by Ancient Greeks, categorical proposition asserts or denies whether one group contain all or some of the members of another group.

In the standard form of categorical proposition, the subject term comes first an the predicate term comes second. Hence, for the given sentence

<em>                                    </em>    <em>"</em><u><em>All bats are mammals</em></u><em>"</em>

The subject term is "bats" and the predicate term is "mammals". Furthermore, it is stated that all bats belong to the category of mammals. Thus, it is an example of proposition A(All S are P).

LenKa [72]

Numerical reasoning tests are often done to assess a person's ability to solve or interpret numerical data. A good source to train numerical reasoning is the use of computer education software's that deals with numerical data, the use of textbooks, self test etc.

<h3>What is done in Numerical reasoning tests?</h3>

Here, an individual is often required to analyze numerical data and then they are expected to draw conclusions from the data, which is often presented in tabular or graphical forms.

A person can improve their numerical reasoning by;

  • Constant Practice
  • Do make a study schedule and keep to it.
  • Do Practice as if you are going for a competition, etc.

A way that a person can  improve their speed in an numerical test is to reduce the time it takes a person to take in the information that is shown in the numerical reasoning questions.

What is the area of the triangle in centimeters<br> squared?
Rashid [163]

Answer:

A = 112cm²

Step-by-step explanation:

Area of a triangle = (bh) / 2

b = base length and h  = height

The triangle shown has a given base length of 14cm and a given height of 16cm

Hence area = ( 16 * 14 ) / 2

16 * 14 = 224

224 / 2 = 112

A = 112cm²
