Answer:

5x + 4

Step-by-step explanation:

Base on the given:

[tex]\mathrm{\frac{9}{3}x+4+2x}[/tex]    → Divide 9 by 3. 9 ÷ 3 = 3

[tex]\mathrm{3x+4+2x}[/tex]    → Combine similar term {2x + 3x = 5x}

The slope of the Function represents the change in height per day.

A line's slope in mathematics is defined as the ratio of the change in the y coordinates to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by Δy and Δx, respectively.

Consequently, the formula for the change in the y-coordinate with respect to the change in the x-coordinate is

[tex]m=\frac{dy}{dx}[/tex] = change in y/change in x

where "m" represents a line's slope.

Additionally, the slope of the line can be shown as

tan θ = Δy/Δx

So, the slope of a line is tanΘ.

So as slope represents a change in y per change in x, in the given question as y is height and x is days, slope changes in height per day.

The slope of the Function represents the change in height per day.

There are 32 home sites on the 8-acre plot.

An acre, a standard unit of measurement used by land sellers, is roughly the same size as a typical football field. An acre is a product of any rectangular land plot with a total area of 4,046 square Metre, or 43,560 square feet. Six plots of 6 x 120 feet each make up an acre.

To find out how many 1/4 acre home sites are on the 8-acre plot, you can divide the total number of acres by the number of acres per home site.

8 acres / 0.25 acres/home site = 32 home sites.

So, there are 32 home sites on the 8-acre plot.

As per the given equation, the percentage of the whole chart that is yellow is 15%.

One quarter of the pie chart is blue, which is 25%.

15% of the pie chart is orange.

When we add the percentages of blue and orange sections, we get 25% + 15% = 40%. So, 40% of the pie chart is blue or orange.

As the other two sections, Yellow and Grey, are equal in size, we can assume that they make up half of the remaining 60% of the pie chart. So each of the Yellow and Grey sections make up 30%/2 = 15% of the pie chart.

The first 8 terms of the sequence are 12, 16, 22, 30, 40, 52, 66, 82 respectively.

(a) The first 8 terms of the sequence are as follows:

a1 = 1 + (1^2) + (2^3) + 2 = 12

a2 = 1 + (2^2) + (2^3) + 3 = 16

a3 = 1 + (3^2) + (2^3) + 4 = 22

a4 = 1 + (4^2) + (2^3) + 5 = 30

a5 = 1 + (5^2) + (2^3) + 6 = 40

a6 = 1 + (6^2) + (2^3) + 7 = 52

a7 = 1 + (7^2) + (2^3) + 8 = 66

a8 = 1 + (8^2) + (2^3) + 9 = 82

(b) Observing the values of a1, a2, a3, a4, and so on, we can see that an > 4n for all n ≥ 3. Hence, a = 3.

(c) We will prove the statement "an > 4n for all integers n ≥ a" using strong induction.

Base case (n=3): a3 = 28 and 28 > 4 * 3 = 12, which is true.

Inductive step: Suppose an > 4n for all integers n = k (k ≥ 3). We need to show that a(k+1) > 4(k+1).

a(k+1) = 1 + (k+1)^2 + (2^3) + (k+1) = 1 + (k^2 + 2k + 1) + (2^3) + (k+1) = an + 2k + 3 > 4k + 3 = 4(k+1)

(d) Observing the values of a1, a2, a3, a4, and so on, we can see that an > 45 for all n ≥ 7. Hence, b = 7.

(e) We will prove the statement "an > 5n for all integers n ≥ b" using strong induction.

Base case (n=7): a7 = 120 and 120 > 7 * 5 = 35, which is true.

Inductive step: Suppose an > 5n for all integers n = k (k ≥ 7). We need to show that a(k+1) > 5(k+1).

a(k+1) = 1 + (k+1)^2 + (2^3) + (k+1) = 1 + (k^2 + 2k + 1) + (2^3) + (k+1) = an + 2k + 3 > 5k + 3 = 5(k+1)

The total number of ounces needed to serve all guests (6 oz/guest * 80 guests) and then divide that number by the size of the bottle (25.4 oz) to get the total number of bottles needed.

In order to calculate the number of champagne bottles needed to serve all 80 guests, we need to use the formula for calculating the total number of ounces needed. The formula is: Number of bottles * size of bottle + total ounces of glasses * number of guests. In this case, the number of bottles needed is: (6 oz/guest * 80 guests)/25.4 oz bottle = 18.9 bottles. Therefore, 19 champagne bottles will be needed to serve all 80 guests. This is because each bottle holds 25.4 ounces and each guest needs 6 ounces of champagne, so we need to calculate the total number of ounces needed to serve all guests (6 oz/guest * 80 guests) and then divide that number by the size of the bottle (25.4 oz) to get the total number of bottles needed.

The equation x + (60 + 70)° = 180° is used to solve for the measure of the vertical angle x = 50°

Vertical angles also called vertically opposite angles are formed when two lines intersect each other, the opposite angles formed by these lines are vertically opposite angles and are equal to each other.

The angle y and x form vertical angles, so x = y

Angle y form a straight line with 60° and 70° so we have the equation to solve for x as:

x + 60° + 70° = 180° {sum of angles on a straight line}

x + 130° = 180°

x = 180° - 130° {subtract 139° from both sides}

x = 50°

Therefore, the measure of the vertical angle x is equal to 50° derived with the equation x + (60° + 70°) = 180°.

What is Quadratic Equation?

The polynomial equations of degree two in one variable of type f(x) = ax2 + bx + c = 0 and with a, b, c, and R R and a 0 are known as quadratic equations. It is a quadratic equation in its general form, where "a" stands for the leading coefficient and "c" is for the absolute term of f. (x).

A = l x w

l = 2w-4

A = w (2w-4)

A = 2w² -4w

96m² = 2w² - 4w

0 = 2w² - 4w - 96 divide both sides by 2

0 = w² - 2w -48

(w-8) ( w +6) = 0

The distance travelled by rick on 2.5 gallons of gasoline is calculated to be 45 mi.

The given function can be written as d = 18 g , where, d is the distance and g is gasoline.

It is also said that, gasoline g = 2.5 gallons

So, to calculate the distance travelled by rick, we should place the value of g in the equation above.

d = 18 g = 18(2.5) = 45 mi

From the graph, the maximum possible gasoline is 10. So, when we place in the above equation, we have,

d = 18 g = 18(10) = 180 gallons

According to the graph the rational function represented in the graph is [tex]F(x) = \frac{x-2}{(x+1 )(x-3)}[/tex], and option A is correct answer.

At the margins of the coordinate plane, the curve approaches lines known as asymptotes. When the denominator of such a rational function gets close to zero, vertical asymptotes happen. Since it would divide by zero, a rational function never traverse a vertical asymptote. A graph's vertical asymptote is a vertical line with the equation x=a, where the graph tends to positive or negative infinity as the inputs go closer to a.

For the given graph we can see that the vertical asymptotes are -1 and 3, and there is no horizontal asymptote.

In option A:

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

The horizontal asymptote is none.

The vertical asymptote is -1 and 3.

Hence, this is the correct option.

Option B:

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

The horizontal asymptote is 0.

The vertical asymptote is 2, -1 , and 3.

Hence, option B is incorrect.

Option C:

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

The horizontal asymptote is none.

The vertical asymptote is 1 and -3.

Hence, option C is incorrect.
