Three pepper plants are present per population density.

You must divide the population by the area's size to determine the population density. Population Density is therefore equal to the number of people divided by the land area.

Since we are working with plants here, the formula is as follows:

Population Density = Plants Per Unit Area

Given,

There are 120 plants.

Area of Land = 5 x 8

= 40 m^2

Just enter the values into the formula now.

Number of People = 120/40

= 3

Consequently, the number of pepper plants per square foot is 3.

When the result of one function is utilized as the input for another, this is known as a composite function. If f(x) = (6x³ - 7)³ and g(x) = 6x³ - 7 then the value of h(x) = x³.

A function is composed in mathematics when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function exists essentially applied to the output of another function.

Function composition is an operation used in mathematics that takes two functions, f and g, and creates a function, h = g ° f, such that h(x) = g. The function g is applied in this operation on the outcome of applying the function f to x.

Let the two functions be f(x) = (6x³ - 7)³ and g(x) = 6x³ - 7.

f(x) = (h° g)(x)

⇒ f(x) = (h(g(x))

If f(x) = (h° g)(x) (6x³ - 7)³ = (h(g(x)) then h(x) = x³.

The complete question is:

Let f(x) = (6x³ - 7)³ and g(x) = 6x³ - 7. Given that f(x) = (h° g)(x), find h(x).

Answer:

h(x) = x³

Step-by-step explanation:

Given:

  [tex]f(x)=(6x^3-7)^3[/tex]

  [tex]g(x)=6x^3-7[/tex]

  [tex]f(x)=(h \circ g)(x)[/tex]

The relationship between f(x) and g(x) is that function f is function g cubed:

[tex]f(x)=(g(x))^3[/tex]

(h o g)(x) means we replace the x-variable of function h(x) with function g(x). So:

[tex](h \circ g)(x)=h(g(x))[/tex]

If (h o g)(x) equals f(x), then h(x) must be h(x) = x³.

Check by replacing the x-variable of function h(x) with the function g(x) and comparing it to f(x):

[tex]\begin{aligned}(h \circ g)(x)&=h(g(x))\\&=(g(x))^3\\&=(6x^3-7)^3\\&=f(x)\end{aligned}[/tex]

Hence proving that h(x) = x³.

Answer: [tex]y=\frac{1}{9}x[/tex]

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes, so the slope of the line we want to find is 1/9.

Since the y-intercept is 0, the equation is [tex]y=\frac{1}{9}x[/tex].

You can graph the lines on a website like Desmos.

Step-by-step explanation:

1.First work out the equation of the line.

1.1 work out gradient

[tex]y = ( \frac{ - 1 - 8}{3 - ( - 2)} )x + c[/tex]

[tex]y = - \frac{9}{5} x + c[/tex]

1.2 substitute in x and y value of one of the two given point. ill use (3;-1).

[tex] - 1 = - \frac{9}{5} (3) + c[/tex]

[tex]c = \frac{22}{5} [/tex]

therefore equation is

[tex]y = - \frac{9}{5} x + \frac{22}{5} [/tex]

2. Now sub in x value of the point you want to test and see if y value correlates.

[tex]y = - \frac{9}{5} (1) + \frac{22}{5} [/tex]

[tex]y = \frac{13}{5} [/tex]

3. We can conclude that point (3;1) does not fall on the graph

Answer: 2.7 kg

1 kilogram (kg) = 2.204623 pounds (lb)

[tex]\frac{6 lb}{1}[/tex] × [tex]\frac{1 kg }{2.204623 lb}[/tex] = 2.721553753 kg

You place 1 kg over 2.204623 lb since they are equal. In the above equation, the pounds (lb) cancel out since one is in the numerator (the number on top of the fraction) and one is in the denominator (the number on the bottom of the fraction). You multiply 6 by the 1 in the numerator and multiply the 1 in the denominator by 2.204623. This turns the equation into:

[tex]\frac{6 kg}{2.204623}[/tex] =2.721553753 kg

You divide 6 by 2.204623 to get 2.721553753

To round to the tenths place, you include only the first number to the right of the decimal, which is 7. Since the number to the right of the 7 is less than five, it stays 7. If it were five or bigger, 7 would turn into 8.

The answer: 2.7 kg

The perfect match leading coefficient for the given polynomial will be as below:-

A. P(x) = (x + 2)(2x - 3)(4x + 7) => 2. 8

B. P(x) = (x-2)(2x - 3)(4x + 7)  => 3. 4

C. P(x) = 5(x-2)(2x - 3)(4x + 7) => 1. 40

D. P(x) = -(x-2)(2x - 3)(4x + 7) => 5. - 8

E. P(x) = (x + 2)(2x - 3)(4x + 7) => 4.  2

Leading Coefficient:

The leading coefficient of the polynomial is means the coefficient of the variable having the highest power in the polynomial.

Given,

Here we have the following list of polynomials,

A. P(x) = (x + 2)(2x - 3)(4x + 7)

B. P(x) = (x-2)(2x - 3)(4x + 7)

C. P(x) = 5(x-2)(2x - 3)(4x + 7)

D. P(x) = -(x-2)(2x - 3)(4x + 7)

E. P(x) = (x + 2)(2x - 3)(4x + 7)

Now, we need to find the matching leading coefficients for this polynomials.

In the given polynomials, we have to calculate the highest power variable in each polynomial with the coefficient. That coefficient is known as the leading coefficients.

First, we have to take the expression A, then we get,

A. P(x) = (x + 2) (2x - 3) (4x +7)

Here we have to multiply the x term alone to get the leading coefficient,

P(x) = (x)(2x) (4x)

Thus will results the leading coefficient as P(x) = 8x³

Similarly, for expression B,

P(x) = 1/2(x - 2) (2x - 3) (4x + 7)

P(x) = 1/2(x) (2x)(4x)

P(x) = 1/2 8x³

P(x) = 4x³

For expression C,

P(x)= 5(x - 2) (2x - 3) (4x + 7):

P(x) = 5(x)(2x)(4x)

P(x)= 40x³

For expression D,

P(x) = -(x - 2) (2x - 3) (4x + 7):

P(x) = -(x)(2x)(4x)

P(x) = -8x³

Finally, for the expression E,

P(x) = 1/4(X + 2) (2x - 3) (4x + 7):

P(x) = 1/4(x)(2x(4x)

P(x) = 2x³

Therefore, the corresponding leading coefficients are 8, 4, 40, -8, and 2 respectively.

The percentage is that indicating the hundredth total number of students surveyed such that 20% of them are 25 will be 125.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

Let's suppose the total number of students that are surveyed was x.

It is known that x% of y is given as, (x/100)y.

Therefore,20% of x is (20/100)x = 0.2x

The 20% of the total students is 25.

So, 0.2x = 25

x = 25/0.2 = 125

Hence "The percentage is that indicating the hundredth total number of students surveyed such that 20% of them are 25 will be 125".

The quadratic function to model the values in the table will be,

y = 3x² + 3x - 3

Option 1 is true.

What is Quadratic equation?

An algebraic equation of the second degree in x is called Quadratic equation.

Given that;

The values of x and y are,

x = -1, 0, 3

y = -3, -3, 33

Let a quadratic function is,

y = ax² + bx + c     ... (i)

Then, It satisfy all the values given in table.

So, Substitute point (x, y) = (-1, -3) in equation (i) we get;

- 3 = a - b + c  ... (ii)

And, Substitute point (x, y) = (0, -3) in equation (i) we get;

-3 = c  .. (iii)

And, Substitute point (x, y) = (3, 33) in equation (i) we get;

33 = 9a + 3b + c ... (iv)

Now, Substitute c = -3 from (iii) in equations (ii) and (iv) we get;

From (ii);

- 3 = a - b - 3

a - b = 0      ... (v)

From (iv);

33 = 9a + 3b - 3

Divide by 3;

11 = 3a + b - 1

3a + b = 12   .... (vi)

Solve equations (v) nd (vi) we get;

a = 3 and b = 3

Thus, Substitute the values a = 3, b = 3 and c = -3 in quadratic equation we get;

y = ax² + bx + c

y = 3x² + 3x - 3

By identifying the y and x-intercepts of the linear equation, we conclude that the correct graph is the third one

We know that the relation between altitude and time is given by the linear equation:

1,500x + y = 35,000

If we isolate y, we get:

y  = -1,500x + 35,000

Notice that when x = 0, we have:

y = -1,500*0 + 35,000

y = 35,000

So the y-intercept is 35,000

And the plane reaches the ground when:

0 = -1,500*x + 35,000

1,500*x = 35,000

x = 35,000/1,500 = 23.3

So it intercepts the x-axis at x  = 23.3

With that in mind, we can see that the correct graph is the third one.
