Step-by-step explanation:

Greetings !

Given expression( function )

[tex]h(x) = \frac{12}{2x} + 16[/tex]

Thus, plug in -8 in the variable x and solve as follows:-

[tex]h( - 8) = \frac{12}{2( - 8)} + 16[/tex]

Multiply the numbers 2.(-8) = -16

[tex] = \frac{12}{ - 16} [/tex]

Apply the fraction rule

[tex] \frac{a}{ - b} = - \frac{a}{b} [/tex]

[tex] = - \frac{12}{16} [/tex]

[tex] = - \frac{ 12}{16} + 16[/tex]

cancle

[tex] \frac{12}{16} = \frac{3}{4} [/tex]

Factor the number: 12 = 4.3

[tex] = \frac{4.3}{16} [/tex]

Factor the number 16 = 4.4

[tex] = \frac{4.3}{4.4} [/tex]

cancel the common factor =4

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

Thus,

[tex] = \frac{ - 3}{4} + 16[/tex]

Convert 16 to fraction :

Apply the fraction rule

[tex]a = \frac{ab}{b} [/tex]

[tex] = \frac{16.4}{4} [/tex]

Multiply the numbers 16.4=64

[tex] = \frac{64}{4} [/tex]

[tex] = - \frac{3}{4} + \frac{64}{4} [/tex]

Answer: 11

Step-by-step explanation: 132/12 = 11

You divide the actual car length by the model and you get the scale factor.

The scale factor of the model to the actual car is 1/11 inches.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Given:

A small model car is 12 inches long and the actual car is 132 inches long.

To find the scale factor:

When both the original dimensions and the new dimensions are known, the scale factor may be determined.

The following is a basic formula to determine a figure's scale factor:

Scale factor = Dimension of the new model ÷ Dimension of the actual car

Scale factor = 12 / 132

Scale factor = 1/11

Therefore, the scale factor is 1/11 inches.

The difference between partitioning a directed line segment MN in a 2:7 ratio versus a 7:2ratio because of following

To understand this let us take the line segment MN which is of a length is divided into 9 equal parts. Here, we are dividing it into nine parts because the proportions 2 and 7 make a sum of 9.

When we divide the line segment MN in the ratio 2:7, the first two parts out of the nine from the left side are separated from the rest 7. This means that the first proportion from the left hand side of the line is smaller than the other.

The equation using the polynomial function is a x⁴ - 6x³ + 7x² + 6x - 8.

According to the statement

We have to find that the equation using the polynomial function.

So, For this purpose, we know that the

A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation

From the given information:

The standard form with zeros 1,-1, 2, and 4:

Polynomial with Zeros 1, - 1, 2 and 4 can be expressed thus :

x = 1 : x - 1

x = - 1 :x + 1

x = 2 :x - 2

x = 4 :x - 4

Hence, we have :

(x - 1)(x + 1)(x - 2)(x - 4) = 0

We can then expand ;

(x - 1)(x + 1) = x² + x - x - 1 = x² - 1

(x² - 1)(x - 2) = x³ - 2x²-x + 2

(x³ - 2x² - x + 2)(x - 4)

x⁴ - 4x³ - 2x³ + 8x² - x² + 4x + 2x - 8

x⁴ - 6x³ + 7x² + 6x - 8.

A circle is a two-dimensional closed figure in which the set of all points with in plane is equidistant from the a given point known as the "centre."

Circle Formula: (x - h)² + (y - k)² = r² ;

Where, (h, k) is the centre & r is the radius of the circle.

Use the distance formula for(-2, 1) and (0,2)

[tex]\begin{aligned}&r=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2} \\&r=\sqrt{(0+2)^2+\left(2-1\right)^2} \\&r=\sqrt{(2)^2+\left(1\right)^2}\end{aligned}[/tex]

Further simplifying;
