Total pay be the at the end of the two weeks with rate of  $13.25 per hour and commission of $150 for selling each new car is $1319.75.

As given,

Rate of salesperson per hour pay = $13.25

Commission on selling each new car =$150

Amount of the pay earned by salesperson:

First week :

25 (13.25) + 3 (150)

= 331.25 + 450

= $781.25

Second week:

18 (13.25) + 2(150)

= 238.5 +300

= $538.50

Total pay of salesperson at the end of two weeks

=$(781.25 +538.5)

=$1319.75

Therefore, total pay be the at the end of the two weeks with rate of  $13.25 per hour and commission of $150 for selling each new car is  $1319.75.

Answer:97.39

Step-by-step explanation:

Given that z₁= −7i and z₂ = 4+3i, the difference z₁ −  z₂ in rectangular form is; -4 - 10i

Addition of complex numbers is basically the same thing as adding two-dimensional vectors that are located on the x-y Cartesian plane.

Now, it is pertinent to note that when doing vector addition, we denote the x-component with i^ and y-component with j^.

We should also not that when adding complex numbers, the x-component is the real part and y-component is the imaginary part.

Geometrically, we can say that the addition of complex numbers can be equated to the addition of vectors in x-y plane.

Thus by the the parallelogram law of vector addition, we will be able to find the resultant vector.

In rectangular coordinates,

z₁ = -7i

z₂ = 4 + 3i

Then, z₁ - z₂ = -7i - (4 + 3i)

= -7i - 4 - 3i

= -4 - 10i

The general equation of a straight line is -

y = mx + c

Where -

[m] is the slope of the line.

[c] is the y - intercept.

Given is the following equation-

g(x) = 3/4 f(x)

Since, the functions are not given, we will assume them by ourselves. You can use the same procedure for any pair of functions of the form -g(x) = n f(x)

Assume that -

f(x) = 2x + 1

Now -

g(x) = (3/4) f(x)

g(x) = (3/4)(2x + 1)

g(x) = (3/2)x + 3/4

Now, both the graphs f(x) and g(x) are attached below. In general, g(x) is a dilated form of f(x) and the dilation scale factor [K] in this case is (3/4).

Both Laquita and Tori wrote a correct equation which is the correct answer would be an option (A).

Let the required line would be as

⇒ y - y₁ = [(y₂ - y₁)/(x₂ -x₁ )](x - x₁ )

Here x₁ = 0 and y₁ = 37

x₂ = 4 and y₂ = 99

The equation of the line is obtained by substituting these values into the above equation;

⇒ y - 37 = (62/4)x

⇒ y - 37 = 15.5x

⇒ y = 15.5x +37

This equation is written by Laquita.

Multiply by 2 both sides of the equation,

⇒ 2y = 31x + 74

⇒ 31x - 2y = 74

This equation is written by Tori.

Therefore, both Laquita and Tori wrote a correct equation.

A maximum of 105 number of 120 kilograms can be loaded in the container.

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Weight of each crate = 120 kg

The greatest weight loaded in the container = 27500 kg

Weight already loaded in the container = 14900 kg

Now,

Since, Weight already loaded = 14900 kg

Let number of 120 kilograms loaded in the container = x.

Hence, Weight of x = 120 kg

So, After combined we get;

Weight nor be greater than the capacity of the container.

Hence, we can formulate;

14900 + 120x ≤ 27500

Subtract 14900 we get;

120x ≤ 27500 - 14900

120x ≤ 12600

x ≤ 12600 ÷ 120

x ≤ 105

Thus, A maximum of 105 number of 120 kilograms can be loaded in the container.

The average speed during the two seconds in which the runner moved from 15 meters from the finish line to 3 meters past the finish line is 9 m/s

The average speed of the runner can be determined by using the following formula;

speed = distance ÷ time

As she moved from 15 meters from the finish line to 3 meters past the finish line in 2 seconds, the total distance covered in these 2 seconds by her can be calculated as follows;

distance = 15 meters + 3 meters

distance = 18 meters

Now substituting the values for distance and time in the formula;

speed = 18 / 2

speed = 9 m/s

Hence the average speed of the runner during the two seconds is calculated to be 9 m/s.

The probability that the randomly selected sample is vulnerable or critically endangered is equal to 0.76

The probability can be determined using the following formula;

probability = number of desired events or outcomes ÷ total number of events or outcomes

The total is known to be 45, the favorable or desired outcomes can be calculated as follows;

number of desired outcomes = number of vulnerable species + number of critically endangered species

number of desired outcomes = 12 + 22

number of desired outcomes = 34

Now we calculate the probability by using the above formula;

probability = 34 ÷ 45

probability = 0.76

Therefore, 0.76 is the probability that the randomly selected species is vulnerable or critically endangered.

From the question, the equation of the function is given as

f (x) = one-third (81) Superscript StartFraction 3 x Over 4 EndFraction

Rewrite the equation properly

So, we have

f(x) = 1/3(81)³/⁴ˣ

Express 81 as 3 exponent 4

So, we have the following equation

f(x) = 1/3(3⁴)³/⁴ˣ

Evaluate the exponents

f(x) = 1/3(3)³ˣ

Further, evaluate the exponents

f(x) = 1/3(27)ˣ

Next, we calculate the key aspects i.e. the domain and the range

The above function is an exponential function.

The domain of an exponent is the set of all real values

Set the radicand to 1, to calculate the range

So, we have

Answer:

Step-by-step explanation:

Given isosceles trapezoid MNFD with short base NF = 6 cm, diagonal ND perpendicular to leg MN, and triangle MND median NX = 5 cm, you want ...

MD is the hypotenuse of right triangle MND. The median from the right angle of a right triangle is half the length of the hypotenuse, so ...

  MD = 2·NX = 2·(5 cm)

  MD = 10 cm

In the attached diagram, we see that right triangle XYN has side XY = 3 (half of NF), and hypotenuse NX = 5 (given). These are two sides of a 3-4-5 right triangle, so the remaining side, altitude h, is 4.

  h = 4 cm

The attache diagram shows congruent side lengths MN and FD are the hypotenuse of a right triangle with sides YM = 2 and YN = 4. The Pythagorean theorem tells us the length of side MN is ...

  MN² = MY² +NY²

  MN² = 2² +4² = 4 +16 = 20

  MN = √20

  MN = FD = 2√5 ≈ 4.47

Triangle MND has a base length MD = 10 and a height h = 4. Triangle NFD has a base length NF = 6 and a height h = 4. The ratio of the areas of these two triangles is ...

  [tex]\dfrac{A_{MND}}{A_{NFD}}=\dfrac{\frac{1}{2}\cdot10\cdot4}{\frac{1}{2}\cdot6\cdot4}=\dfrac{10}{6}=\boxed{\dfrac{5}{3}}[/tex]

The ratio between the areas is 5 : 3.

__

Additional comment

We are also given the area of the trapezoid as 32 cm². That can be used to find the longer base and/or the altitude, or to check the answers we have for those values. It is redundant information.

The midpoint X of MD is the center of the circumscribing circle of the trapezoid and right triangles MND and MFD. The midpoint of the hypotenuse of a right triangle is always the circumcenter, so knowing the length NX tells us the radius of that circle, hence MX and XD.
