For this case we have the following expression:

[tex](-4) (- 4)[/tex]

Using law of exponents we have:

[tex](a ^ m) (a ^ n) = a ^ {m + n}[/tex]

We use the definition to rewrite the given expression

Rewriting we have:

[tex](-4) (- 4) = (- 4)^{ 1 + 1}\\(-4) (- 4) = (- 4) ^ 2[/tex]

Answer:

The rewritten expression is given by:

[tex](-4) (- 4) = (- 4) ^ 2[/tex]

Points A, B and Q are coplanar.

Points or lines are said to be coplanar if they lie in the same plane. Example 1: The points P , Q , and R lie in the same plane A . They are coplanar.

A line which is in the same plane as another line. Any two intersecting lines must lie in the same plane, and therefore be coplanar.

Three or more points that lie on the same line are collinear points . Example : The points A , B and C lie on the line m.

From the figure we can observe

Points A, B and Q are not in the same line.

Three points are collinear only if they are on the same line

3 points are collinear if we can draw a line that connects the points.

In the image A, Q are in a same line but B is not in the line of A and Q.

Points A, B and Q are on the base, So the three points are coplanar but not collinear.

So, Points A, B and Q are coplanar.

Answer: The correct option is C. The domain of  [tex](b\circ a)(x)[/tex]  is  [tex][0,\infty)[/tex].

Explanation:

It is given that,

[tex]a(x)=3x+1[/tex]

[tex]b(x)=\sqrt{x-4}[/tex]

First we have to find the composite function [tex](b\circ a)(x)[/tex].

[tex](b\circ a)(x)=b(a(x))[/tex]

[tex](b\circ a)(x)=b(3x+1)[/tex]

[tex](b\circ a)(x)=\sqrt{3x+1-4}[/tex]

[tex](b\circ a)(x)=\sqrt{3x-3}[/tex]

We know that a root function is defined for only positive values therefore the composite function is defined if,

[tex]3x-3\geq 0[/tex]

[tex]3x\geq 3[/tex]

[tex]x\geq 1[/tex]

The function is defined for all the values of x which are greater than or equal to 1. Therefore the domain of  [tex](b\circ a)(x)[/tex]  is  [tex][0,\infty)[/tex] and option C is correct.

Answer:

b: 2x + 1 = 73

Step-by-step explanation:

Let x be the smaller integer,

Then the larger integer consecutive to x is x + 1,

Sum of these integers = x + x + 1 = 2x + 1

According to the question,

The sum is 73

⇒ 2x + 1 = 73

Which is the required equation that could be used to solve the problem.

Option 'b' is correct.

The recommended method of pay must be salaried because, salaried employee will get more money than hourly paid employee per week.

Further explanation:

Given:

The salary of an employee is [tex]\$\ 78,000[/tex].

The hourly employee get paid is [tex]\$26\text{ /hour}[/tex] and after [tex]40[/tex] hour the employee get [tex]\$39\text{ /hour}[/tex].

Calculation:

The number of week in a year is [tex]52[/tex].

Therefore the salary of the employee per week can be obtained as follows:

[tex]\begin{aligned}\text{Salary per week}&=\dfrac{78000}{52}\\&=15000\end{aligned}[/tex]  

The salary of the employ per week is [tex]\bf \$\ 1,500[/tex].

The number of hours worked by the hourly paid employee in the week is [tex]47\text{ hours}[/tex] since the sum of all the hours of the week is [tex]47[/tex].

The hourly paid employee works extra [tex]7\text{ hours}[/tex] per week.

The amount earned by hourly paid employee can be obtained as follows:

[tex]\begin{aligned}\text{Amount earned}&=(26\cdot 40)+(7\cdot 39)\\&=1040+273\\&=1313\end{aligned}[/tex]

Therefore, the dollars earned by the hourly paid employ per week is  [tex]\$\1,313[/tex]

Since, the salaried employee make more money than and hourly paid employee per week.

Therefore, the highly recommended method of pay for new employee must be salaried.

Keywords:  Employee, $26, hourly, 40 hours, $78,000, Salaried, per year, hours, payment ,working hours, hourly, hourly paid employee, more money.

The payment options would you recommend to a new employee is $1150.

The salary of $67,000, when divided by 52 weeks, results in a weekly payment of $1288.

For standard hourly employees working 44 hours per week, the breakdown is as follows: 40 regular hours at $25 per hour amounting to $1000, with an additional 4 hours of overtime at $37.50 per hour, totaling $150.

This computation reflects a fair compensation structure that considers both regular working hours and overtime, ensuring equitable remuneration for employees based on their hourly rates and the hours worked beyond the standard weekly timeframe.

Consequently, the total weekly compensation for hourly employees is $1150.

Final answer:

A postulate becomes a theorem through a process of logical deduction and proof. Starting from basic assumptions or postulates, mathematicians derive theorems using step-by-step logical inferences, forming the basis for further deductions, such as with Newton's second law or the Schrödinger equation in physics.

Explanation:

A postulate is a statement assumed to be true without proof and serves as a starting point for deducing and inferring other truths. The transformation from a postulate into a theorem involves a process of logical deduction and rigorous proof. When we establish a theorem, what we're doing is showing that the statement necessarily follows from the previously accepted postulates and theorems by a sequence of logical deductions. For example, in geometry, one might postulate that a straight line can be drawn between any two points, and from there, using a series of logical steps, derive the Pythagorean theorem. The Pythagorean theorem's validity is then supported by the fact that it can be derived from these fundamental postulates through a sequence of unassailable logical steps within a proof.

To illustrate, a textbook might first introduce a straightforward theorem like: "If we start out with four lines that form a rectangle, we can draw a new, fifth line that divides the rectangle into two identical triangles." From this, using the fifth line as a postulate, more complicated theorems can be constructed. Similarly, in physics, Newton's second law (f = ma) and the Schrödinger equation in quantum mechanics begin as postulates that explain a wide range of observations. Once propositions like these are established, they can be used to deduce further principles that build upon them.

Answer:

x = 43.25

Step-by-step explanation:

In the given figure :

In ΔDEF ,

DF = FE

⇒ ∠DEF = ∠FDE = x ( Angles opposite to equal sides are equal)

Now, using angles sum property of a triangle in ΔDEF

∠DEF + ∠FDE + ∠DFE = 180

⇒ ∠FDE + ∠FDE + 93.5 = 180

⇒ x + x = 180 - 93.5

⇒ 2x = 86.5

⇒ x = 43.25

Answer:

10 or answer B.

Step-by-step explanation:

Using the distance formula, we can calculate the distances between the vertices of quadrilateral JKLM. After performing these calculations, we can determine that not all sides have the same length, thus quadrilateral JKLM is not a rhombus.

To determine if quadrilateral JKLM is a rhombus, we need to check if all four sides are of equal length because a defining property of a rhombus is that it has all sides of equal length. The length between two points (x1, y1) and (x2, y2) can be found using the distance formula which is √[(x2-x1)² + (y2-y1)²].

After calculating, we find:
J-K distance = √[(5-2)² + (-3-3)²] = √42
K-L distance = √[(-1-5)² + (9-3)²] = √52
L-M distance = √[(-3- -1)² + (2-9)²] = √52
M-J distance = √[(2- -3)² + (-3-2)²] = √42

Therefore, the distance between vertices J-K and L-M are the same, and the distance between vertices K-L and M-J are the same, but the two pairs are not in themselves equal to each other. As such, quadrilateral JKLM is not a rhombus because all sides do not have the same length.

Answer:

Step-by-step explanation:

The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.

Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.

Next, when the plane lands in New York the altitude will touch the horizontal axis.

Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.

Lastly the altitude will touch the axis when plane lands back in Chicago.

So, cumulatively the altitude will touch the horizontal axis seven times.

The altitude vs time graph for the plane's journey will touch the horizontal axis 6 times - at each landing during the round trip from Chicago to New York and back.

The graph of the plane's altitude versus time will touch the horizontal axis each time the plane lands. The plane lands at the 3 intermediate stops on the way to New York, once in New York, at the 1 intermediate stop on the way back, and once back in Chicago. This totals up to 6 times. Skyward journeys will create upward curves on the graph while the landings create points where the graph touches the horizontal axis (indicating an altitude of 0 at landing).
