The most appropriate choice for function will be given by-

The first option is correct

What is a function?

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Here,

For the first table,

Slope of function from x = 1 to x = 2

= [tex]\frac{1 - \frac{1}{2}}{2 - 1}[/tex]

=[tex]\frac{1}{2}[/tex]

Slope of function from x = 2 to x = 3

= [tex]\frac{\frac{3}{2}-1}{3 - 2}[/tex]

= [tex]\frac{1}{2}[/tex]

Slope of function from x = 3 to x = 4

= [tex]\frac{2-\frac{3}{2}}{4 - 3}[/tex]

= [tex]\frac{1}{2}[/tex]

Here the slope is same. So the function is linear

For the second table,

Slope of function from x = 1 to x = 2

= [tex]\frac{\frac{1}{2} - 1}{2 - 1}[/tex]

=[tex]-\frac{1}{2}[/tex]

Slope of function from x = 2 to x = 3

= [tex]\frac{\frac{1}{3}-\frac{1}{2}}{3 - 2}[/tex]

= [tex]-\frac{1}{6}[/tex]

Here the slope is not same. So the function is not linear

For the third table,

Slope of function from x = 1 to x = 2

= [tex]\frac{9 - 7}{2 - 1}[/tex]

= 2

Slope of function from x = 2 to x = 3

= [tex]\frac{13 - 9}{3 - 2}[/tex]

= 4

Here the slope is not same. So the function is not linear

For the Fourth table,

Slope of function from x = 1 to x = 2

= [tex]\frac{6 - 0}{2 - 1}[/tex]

=[tex]6[/tex]

Slope of function from x = 2 to x = 3

= [tex]\frac{16 - 6}{3 - 2}[/tex]

= 10

Here the slope is not same. So the function is not linear

So the first option is correct

We have that in 70 minutes 120 players of an orchestra play Beethoven's 9th symphony because it always lasts 70 minutes.

The lenght of a musical piece does not depend in the number of musicians playing it. The orchestra could have 2 violinists more or less and they still will play the same 70 minutes musical piece.

Then, an orchestra of 60 players would take the same 70 minutes to play Beethoven's 9th symphony.

The orthogonal trajectories of the family of curves y² = 6Kx³ will be [tex]y = \sqrt{6(C-\frac{x^2}{4}}[/tex]

An orthogonal trajectory of a family of curves is any curve that forms right angles with each member of the family. The curve does not always have to cross each member of the family.

It is given that,

y² = 6Kx³

Differentiate both sides we get,

[tex]\rm 2y = 6k(3x^2) \frac{dy}{dx} \\\\ \frac{dy}{dx} =\frac{2y}{18Kx^2}[/tex]

Substitute the value of K as

[tex]\rm K = \frac{y^2}{6x^3}[/tex]

[tex]\frac{2y}{18(\frac{y^2}{6x^3})x^2} = \frac{dy}{dx} \\\\ \frac{dy}{dx} = \frac{2x}{3y}[/tex]

Consider the negative reciprocal to find the perpendicular slope.

[tex]\frac{-3y}{2x} =\frac{dy}{dx} \\\\ - \int {\frac{1}{2x} \ dx = \int \frac{1}{3y} dy \\\\[/tex]

[tex]-\frac{x^2}{4}+C = \frac{y^2}{6}[/tex]

Simplify,

[tex]\rm 6(-\frac{x^2}{4}+C)= y^2 \\\\ y = \sqrt{6(C-\frac{x^2}{4}}[/tex]

Thus, the orthogonal trajectories of the family of curves y² = 6Kx³ will be [tex]y = \sqrt{6(C-\frac{x^2}{4}}[/tex]

Given the system of equations:

-3y + 4x = 4

To find how many times the lines will intersect. let's solve the system of equation using substitution method.

8x - 6y = 3 ........................................1

-3y + 4x = 4 ......................................2

From equation 1, make x the subject:

8x - 6y = 3

8x = 3 + 6y

We have:

Multiply through by 2 to eliminate the fraction:

Since we have 0 = 5, it means the system of equations has no solution.

Therefore, the lines will not intersect, because this system has no solution.

ANSWER:

A. The lines will not intersect, because this system has no solution.

The given system of equation :

x +2y =4

2x -2y =5

On adding both equation we get

x+2y+2x-2y=4+5

3x=9

x=3

So, for y, substitute x=3

x+2y=4

3+2y=4

2y=4-3

2y=1

y=1/2

The solutions is (3,1/2)

The system of linear equation have infintely many solution if they are coincidient, i.e. slope are equal

The given expression :

x+2y =4

2y=4-x

y=(4-x)/2

y = 2-x/2

So slope is (-1/2)

The second equation : 2x-2y=5

2y=2x-5

y=(2x-5)/2

y=x-

The number of couches manufactured and sold in order to maximise the profit is 1560.

The demand function will be

p = 2700 - 0.75x

Here p = price per couch and x = number of couch

Total Fixed cost = $760000

Variable cost per couch = $360

Total cost = Fixed cost + variable cost

T(x) = 760000 + 360x

Revenue function will be

R(x) = Px

(2700 - 0.75x)x

2700x - 0.75x²

Since profit function = Pr(x)

Pr(x) = R(x) - T(x)

= 2700x - 0.75x² -760000 -360x

- 0.75x² + 2700x - 360x - 760000

For maximum profit

[tex]\frac{d}{dx}(Pr(x)) = 0[/tex]

[tex]\frac{d}{dx}[-0.75x^{2} + 2340x -760000 ] = 0[/tex]

-1.5x + 2340 = 0

x = 2340/1.5

x = 1560

The couches sold for maximum profit = 1560

Therefore, the number of couches manufactured and sold in order to maximise the profit is 1560.

A) The inequality for the situation is 41x + 16y < 6900

B) The painter can work less than 97 hours without exceeding the budget of Hanson.

Given,

The total money spend by Hanson = < $6900

The charge for carpenters = $41 per hour

The charge for painters = $16 per hour

A) We have to find an inequality for this situation.

Lets take,

Carpenters working hours = x

Painters working hours = y

So, the inequality will be like:

41x + 16y < 6900

B) Now, we have to find the number of hours the painter can work without exceeding his budget if he hires carpenter.

Carpenters working hours = 50

Then, the charge will be = 50 × 41 = 2050

Then,

6900 - 2050 = 4850

The balance amount will be less than 4850.

So, the working hours of painter:

y < 4850 / 50

y < 97

That is, the painter can work less than 97 hours without exceeding the budget of Hanson.

Normal distributions are crucial to statistics because they are widely used in the natural and social sciences to represent real-valued covariates whose distributions are unknown.

First we will find the bottom 3% such that P(X ≤ x) = 0.03

⇒ [tex]P(\frac{X-5.48}{0.07}\leq \frac{x-5.48}{0.07} )=0.03[/tex]

⇒[tex]P(Z\leq \frac{x-5.48}{0.07} )=0.03[/tex]

Now we will use the normal table to calculate the corresponding z-score.

[tex]\frac{x-5.48}{0.07} =-1.88\\\\\implies x = 5.348[/tex]

Now we will find the same for the top part of the distribution.

[tex]P(\frac{X-5.48}{0.07}\leq \frac{x-5.48}{0.07} )=0.97\\\\\implies P(Z\leq \frac{x-5.48}{0.07} )=0.97[/tex]

Now we will use the normal table to calculate the corresponding z-score.

[tex]\frac{x-5.48}{0.07} =1.88\\\\\implies x = 5.612[/tex]

3)  f (3) = 3×2 = 6

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

A function is a type of rule that produces one output for a single input.. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is the input value, we would state that y is a function of x.

Given : Functions are f(x) = 3x + 5 ------- 1

f(x)=x²-1.5 --------- 2 and f(x) = 2x -----------3

Thus when we put x = 3 we will get the following values that is ;

1 becomes  f (3) = 3 × 3 + 5 = 14

and 2 becomes f( 3 ) = (3)² - 1.5 = 7.5
