Since there are only two (2) sellers in the town with many buyers, the competitive situation which Jameson's Grocery is experiencing is an oligopoly.

An oligopoly can be defined as a market structure which comprises a small number of business firms (sellers) that are offering identical (similar) products to many buyers, wherein none of the sellers can limit the significant influence of others.

In this scenario, we can infer and logically deduce that the competitive situation which Jameson's Grocery is experiencing is an oligopoly because there are only two (2) sellers in the town with many buyers (1,000 students).

The angle of depression from the top of the flag pole to point A is 36.2 degrees.

From trigonometric ratio: cos(θ) = Adjacent / Hypotenuse

Given that;

cos(θ) = Adjacent / Hypotenuse

Cos(θ) = 25ft/31ft

Cos(θ) = 0.80645

θ = cos⁻¹( 0.80645 )

θ = 36.2°

Therefore, the angle of depression from the top of the flag pole to point A is 36.2 degrees.

Answer:

a₃ = 19

Step-by-step explanation:

to find the third term substitute n = 3 into the nth term rule

a₃ = 4(3) + 7 = 12 + 7 = 19

Answer:

a₃ = 19

Step-by-step explanation:

the relationship between any two terms of an arithmetic sequence (in our case the relationship between the 3rd term and nth term)  gives us this equality :

[tex]a_n - a_3 = 4(n-3)[/tex]

Then

4n + 7 - a₃ = 4n - 12

Then

7 - a₃ = - 12

Then

7 + 12 = a₃

Then

a₃ = 19

The mid point between the two points is at 13/8 .

A line segment is  a line of fixed measure .

The line segment extends from (-3/4) to  [tex]\rm 2 \dfrac{1}{2}[/tex]

i.e the line extends form -3/4 to 5/2

To find the mid point , the total distance needs to be determined

So the distance between the two point is

(5/2) + (3/4) = 13/8

The mid point is at half the distance of this

so it is at 13/8 from both the points

Any point at 13/8 distance from 5/2  towards (-3/4) will be

= (5/2) - (13/8)

= 7/8

So the mid point between the two points is at 13/8 .

Pedro Fernández should advice his client to go with the second mutual fund named as Fund Corporation. This is because, it showed an higher average return over the five-year period at an average of 11% beating Trujix Inc by 3%.

To get the better fund, Pedro must calculate a simple average of the interest rates of the various funds over the past 5 year period.

Trujix Inc 5-Year Average

(12 + 10+ 3 +9 + 11)/5

= 45/5

=9%

Fund Corporation 5-Year Average

(13 + 12 +14 + 10+ 6)/5

= 55/5

(x + 7) (3x + 1) = 3x² + 22x + 7

This question introduces the concept of polynomial long division.

This is what we are

Given: (3x² + 22x + 7) ÷ (x + 7) = 3x + 1

Now, from the concept of polynomial long division, we can see that:

if, f (x) ÷ g (x) = h (x),

This means that we can write:

f (x) = g (x) × h (x)

Applying the same concept to the question, we can also say:

(3x² + 22x + 7) ÷ (x + 7) = 3x + 1,

Next; (x + 7) (3x + 1) = 3x² + 22x + 7

The months with temperature below 0° is August and October.

GIven,

T(m) = 4 sin (π/6 m)₊2

In the above equation, T(m) is the average temperature in a month in degrees Fahrenheit, and m is the month of the year.

T(8) = 4 sin (8π/6 m)₊2

       = 4 sin (4π/3 )₊2

       = 4 sin (π₊π/3 )₊2

       = ₋4 sin π/3 ₊2

       = ₋4×√3/2 ₊2

       = ₋2√3 ₊ 2 <0

The function for the average monthly temperature, in m months from january is given by

T(0) = 4 sin(10π/6) ₊ 2

       = 4 sin(5π/3) ₊ 2

       = 4 sin(2π ₋ π/3) ₊ 2

"Draw a ray with one endpoint" demonstrates the correct first step in copying an angle. This is further explained below.

In general, the distance (which is sometimes stated as a degree) that occurs between two crossing lines or surfaces at or near the point where they meet. This distance might be positive or negative.

The formation of an angle is caused by the conjunction of two rays at a single point in space. The split or 'opening' that can be seen between these two rays is referred to as a 'angle,' and the symbol denotes this particular angle. The degree is the standard unit of measurement for angles, and its values include things like 60 degrees and 90 degrees, amongst other possible combinations.

In conclusion, "Draw a ray with one terminal" illustrates the correct first step in duplicating an angle. This step shows how to replicate an angle.

The exponential function is [tex]f(x) = 18(12)^{-x-4} + 2[/tex]

An exponential function is represented as:

y = b^x

Where b represents the base.

The base is given as:

b = 12

So, we have:

y = (12)^x

It is vertically compressed by a factor of 1/8.

So, we have:

y = 18(12)^x

When reflected across the y-axis, we have:

[tex]y = 18(12)^{-x}[/tex]

The horizontal asymptote is y = 2.

So, we have:

[tex]y = 18(12)^{-x} + 2[/tex]

It passes through the point (-3, 4).

So, we shift the function to the right by 4 units

[tex]y = 18(12)^{-x-4} + 2[/tex]

Express as a function

73 is a 46% increase of 50.

What is percentage ?

A percentage is a relative value that represents the hundredth part of any quantity. One percent (symbolized 1%) is a hundredth part; thus, 100 percent represents the entire amount and 200 percent specifies twice the given amount.

Percentage is defined as a specific part or amount out of a hundred. It is a fraction with the denominator 100 and is denoted by the symbol "percent."

The percent increase formula is as follows:

Percent increase = [(new value - original value)/original value] * 100.

Number of car parking (original value)=50

Number of car parking(new value)=73

The Percentage increase =[(73-50)/50]*100

                                          = [(23)/50]*100  

                                          =.46*100
