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 probability that a randomly selected patient is 0-12 years old given that the patient suffers from ankle pain is 4/7.

Probability is used to determine the likelihood that a random event would happen. The odds that the random event happens has a probability value that lies between 0 and 1. The more likely it is that the event would occur, the closer to one, the probability value would be.

The probability that a randomly selected patient is 0-12 years old given that the patient suffers from ankle pain = number of 0 - 12 that suffer from ankle pain / total number of people that suffer from ankle pain

= 4 / (4 + 3) = 4 / 7

The formula for the line that intersects at (8,-5) and is parallel to line x+y = 8 is given by the algebraic expression y = -x +3.

What is Algebraic expression?

The Algebraic expression in this case is:

x + y = 8

which traverses points (8,-5)

Let's start by utilizing the point-intercept equation of line, which is provided by: to determine the slope of line m, that is parallel towards the line x + y = 8.

y = mx + c →(1)

x + y = 8

y = -x + 8

Comparing the aforementioned Algebraic expression to equation (1), we obtain

m = -1

The slope of the line parallel to the line x + y = 8 will now be the same, and it will be m = -1.

Let's use the point-slope equations of line to determine the linear equation now:

(y-y₁) = m(x-x₁)

Changing every value in the equation above to obtain the Algebraic expression for a line

(y-(-5)) = -1(x-8) (x-8)

(y+5) = -x+8

y + 5 = -x +8

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

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

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

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.
