The linear equation that represents the given literal problem is  3x+12= 28.50 (letter D) and Ava pays $5.5 (letter B)  for each pumpkin.

An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=9x+5. Where:

m= the slope.

b= the constant term that represents the y-intercept.

For the given example: m=9 and b=5.

The exercise presents two questions, before solving them, you should convert the given text information into equations.

Data question

     1) Question 1

     Here you should write a linear equation that represents the given problem. Thus, you can write

    3x+12= 28.50

    Since 3x represents the payment of pumpkins and the value 12 is the difference between the total of Ava´s money and the total cost of pumpkins.  

    Therefore, the answer to question 1 is the letter D ( 3x+12= 28.50)

   2) Question 2

As you know the equation that represents the problem, for solving this question you need to find the value of x.

    3x+12= 28.50

     3x=28.5-12

    3x=16.5

      x=16.5/3

      x=5.5 (letter B)

The factors of the quadratic function  p(x) is equal to

(x + 5 + √(65)/2)(x - 5 + √(65)/2).

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, The zeros of the quadratic function p(x) = x² - 5x - 10 are,

(5 + √(65)/2, 5 - √(65)/2).

The height of the school is given by the equation H = 13.274 m

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the height of the building be represented as ED = H

Let the distance of mirror from the building be CD = 11.15 m

The distance walked extra from the mirror CB = 1.05 m

The distance of Fawzia's eyes to the ground AB = 1.25 m

Now , let the triangles be represented as ΔABC and ΔCED ,

where both the triangles are similar and have a common angle

So , the corresponding sides of similar triangles are in the same ratio

And , ED / AB = CD / CB

Substituting the values in the equation , we get

ED / 1.25 = 11.15 / 1.05

Multiplying by 1.25 on both sides of the equation , we get

The height of the school building ED = ( 11.15 x 1.25 ) / 1.05

The lowest score for the normally distribution with mean 72 and standard deviation 8 is equal to 82.

Mean of the normally distributed data 'μ' = 72

Standard deviation 'σ ' = 8

Lowest score with 10% ( 90percentile )

z = InvNorm(0.90)

 = 1.28

Let 'X' be the lowest score for the normal distribution

z = ( X - μ ) / σ

Substitute the values we get,

⇒ 1.28 = ( X - 72 ) / 8

⇒ X - 72 = 1.28 × 8

⇒ X = 10.24 + 72

⇒ X = 82.24

⇒ X = 82 ( round to an integer )

In order in which the boxes appear:

[tex]\boxed{a\sqrt{2}}[/tex]

[tex]\boxed{a\sqrt{2}}[/tex]

[tex]\boxed{a\sqrt{2}}[/tex]

Step-by-step explanation:

At any coordinate (x , y) the distance from the origin (0, 0) is computed by the distance (Pythagorean formula) as:

d = [tex]\sqrt{x^2+y^2}[/tex]

Since x = y = a for both ants, the distance is

[tex]d = \sqrt{a^2+a^2}\\\\d = \sqrt{2a^2}\\\\d = \sqrt{a^2}\cdot \sqrt{2}\\\\d = a\sqrt{2}[/tex]

It does not matter whether both coordinates are positive or both negative since we are taking the squares of the coordinates and distance is always positive

a)  If the tank is initially full, it will take  14.31 min. long to  tank to empty

b) If the height of the water is initially 10 feet, it will take 1.67 min for the tank to empty.

For the first case, we  have the differential  equation governing the height of the water, where the volume of a cone  is  V= 1/3 πr^2h by the similar triangles  we can conclude that  what the  value  will be  for the height, the cone  shape will always have the same relation  with the  radius of the water r/h=8/20⟹r=2/5h⟹r^22=4/25h^2, so V= 4/75πh^3, we will  take the derivative of the  height  of with respect to time t

dV/dt=4/25πh2 dh/dt, now converting into inches  we get  :

dV/dt=−cAh√2gh=−3/5(π(1/6)^2)√64h=−24π/5⋅36 √h=−2π/15√h.

now adding  both the  equations of   dV/dt,

425πh^2dhdt=−2π15√h⟹dhdt=−56h−3/2.

since the tank is empty m  it will happen in at h=0, so for the value of t  we will solve for h(t). after  solving  this differential equation using  the separation of  variables : dh h^3/2=−5/6dt, after  integration of both sides, we get: 25h5/2=−5/6t+C0⟹h5/2=−25/12t+C, since  here the intial height is  20 feet , so h(0)=20, Therefore  20^5/2=−25/12(0)+C⟹C=20^5/2, so h(t)=(−25/12t+20^5/2)^2/5.so  when  h  will be 0 , then −25/12t+20^5/2=0⟺25/12t=205/2⟺t=12/25 20^5/2≃858.65 s=14.31 min.

For the second case, the relationship between the height and radius is different, here the angle between the side of the tank and the vertical is  30 degrees, and the ratio of the radius and height of the tank is √3:1, which is also the ratio of height and radius of the water.  

1/√3=r/h⟹r=h/√3⟹r^2=h^2/3.

V=1/3πr^2h=π/9h^3, to solve it  we need to for dVdt, to  find the height and  rate of  change of height :dV/dt=π/3h^2dhdt here c is 0.6 and Ah=1/9π, dVdt=−35⋅19π⋅8√h, adding up those equations we get dV/dt, we have   π/3h^2dh/dt=−8π/15√h⟹dh/dt=−8/5h^−3/2,  now apply the separation of variables:

h^3/2dh=−8/5dt⟹2/5h^5/2=−8/5t+C, here the initial was at t=0, h is 11, C will be 2/5 11^5/2, therefore h(t)=−8/5t+2/5 11^5/2, so the time when the tank is empty will be  0=−8/5t+2/5 11^5/2⟺85t=25 11^5/2⟺t=1/4 11^5/2= 100.33 s=1.67 min.

The advantages of bar charts over pie charts while graphing the given data are discussed below.

A bar chart or bar graph is a visual representation of categorical data that uses rectangular bars with heights or lengths proportional to the values they represent. The possibility of a bar plot, both vertical and horizontal, exists. Vertical bar graphs are also referred to as column charts.

A circular statistical image known as a pie chart uses slices to represent numerical proportions. Each slice's arc length in a pie chart varies depending on the amount it represents.

Any numbers can be chosen for the numeric value axis in a bar chart.

Pie charts can only be used if the sum of the various parts equals a meaningful whole because they are intended to illustrate how each portion contributes to the whole.

Hence bar chart is more advantageous over pie chart when more information is to be presented through charts.

The profit function P(x) can be found by subtracting the cost function C(x) from the revenue function R(x), where R(x) = p * x:

So, we have

P(x) = R(x) - C(x)

Substitute the known values in the above equation, so, we have the following representation

P(x) = (285 - 4x) * x - (128 + 16x)

So, we have

P(x) = 285x - 4x^2 - 128 - 16x

Evaluate the like terms

P(x) = 269x - 4x^2 - 128

To find the profit for making and selling 3 million fans, we substitute x = 3 into the profit function P(x):

P(3) = 269(3) - 4(3)^2 - 128

P(3) = 643

A hyperbola is a type of conic section that is the result of intersecting a right circular cone with a plane that is perpendicular to one of its sides, and is oblique to the other. It is defined by two curves that are mirror images of each other and are each a set of all points such that the difference of their distances from two fixed points, called the foci, is a constant value.

A hyperbola can be represented in standard form as an equation, where the x and y terms are squared and the constant terms have opposite signs. It can also be graphed in the coordinate plane, where it appears as a set of two open curves, each going off to infinity in opposite directions.

The height of the vase can be found by using the formula for the height of a hyperbolic paraboloid, which is given by:

h = e × c × √(1 + (2a/c)²)

where h is the height of the vase, e is the eccentricity, a is the width at the narrowest point (4 inches), and c is the average width of the opening and base (6 inches).

Plugging in the values, we get:

h = 2.5 × 6 × sqrt(1 + (2 × 4 / 6)²)

h = 2.5 × 6 × sqrt(1 + (2 × 2)²)
