**Answer:**

116

**Step-by-step explanation:**

Given the **ratio 1.2 : 29**, you want x in the **equivalent ratio 4.8 : x**.

Equivalent ratios can be written as a proportion:

1.2/29 = 4.8/x

SolutionMultiplying by 29x, we have ...

1.2x = 29(4.8)

Dividing by 1.2 gives ...

x = 29(4.8/1.2) = 29(4) = 116

**The ratio is the same as 4.8 to 116**.

*Additional comment*

A proportion like this can be written 4 ways. The solution takes only one step if the unknown is in the numerator.

[tex]\dfrac{1.2}{29}=\dfrac{4.8}{x},\quad\dfrac{29}{1.2}=\dfrac{x}{4.8},\quad\dfrac{1.2}{4.8}=\dfrac{29}{x},\quad\dfrac{4.8}{1.2}=\dfrac{x}{29}[/tex]

which expression is a factor xsquared - 5x-6

The **Factors** of x² - 5x + 6 are (x-3) (x-2)

Step 1: Add the **constant term** to the first term's coefficient. i.e (6 x 1) = 6

Step 2:Find the two factors of 6 whose total matches the **middle term's** coefficient., i.e -5.

Thus, the factors are -3 and -2 as,

-3 × (-2) = 6 (**Product**)

-3 + (-2) = -5 (**Sum**)

The** polynomial **may be expressed as follows after dividing the middle term by the **two components**, -3 and -2:

x² - 3x - 2x + 6 = 0

⇒ x(x-3) -2(x-3) = 0

⇒ (x-3)(x-2) = 0

Thus, the **Factors** of x² - 5x + 6 are (x-3) (x-2).

Determine the average rate of change of f(x) = 4x²+x+3 over the interval [-2, 2].

**Answer:** The average rate of change is 1.

**Step-by-step explanation:**

The average rate of change f(x) on the interval [a,b] is (f(b)−f(a))/(b−a)

a=−2 , b=2, f(x)=4X^2+x+3.

(f(b)-f(a))/(b-a)= (3+(2)+4(2)^2-(3+(-2)+4(-2)^2)) / (2-(-2)) = 1

Write the rule for the table, use z for the input.Input-1Output7012co woo WN3.4F(0)

Lets assume that the input values are x values and the output values are y values.

Then you will have pairs of coordinate values as shown;

(-1,7) , (0,2) , (1,-3) , (2,-8), (3,-13), (4,-18)

Using the coordinates find the slope a;

(-1,7) and (0,2) ---------slope is change in y-values/ change in x-values , (2-7) /(0--1)

= -5/ 1 = -5

Do the same for the next pair of coordinates ,(0,2) and (1,-3) , (-3-2) / (1-0) = -5/1 = -5

If you continue the procedure to the next pair which is (1,-3) and (2,-8) to get the slope as : (-8- -3) / (2-1) = -5/1 = -5

This means that the slope is -5

The relation will be represented by the equation y= mx + c where m is the slope and c is the y-intercept

First plot the points to visualize the graph

From the plot, you notice that when the points are joined, a straight graph is formed sloping to the negative side and intersecting the y-axis at point (0,2).

So to determine the rule, we apply the equation y= mx + c with m= -5 and c =2

This gives y= -5 x + 2

A side mirror of a small pick up truck is similar to that of a larger full size pickup truck. If the smaller truck has a rectangular side mirror of width 5.0 in. and height 6.0 in., what is the height in inches of the larger mirror if the width is 10.0 in.?

If the** width** of larger full size pickup truck is 10.0 in. then its **height** is equal to **12inches.**

As given in the question,

Side mirror of a small pick up truck is similar to larger full size pick up truck.

Smaller truck has rectangular side mirror

**Width** = 5.0 in.

**Height** = 6.0 in.

Larger mirror

Width = 10.0 in.

Let h be the height of the larger mirror

Both the mirrors are similar and rectangular in shape.

Hence, sides are in proportion

5 /6 = 10 /h

⇒h = (6 ×10) / 5

⇒ h = 12 in.

Therefore, if the** width** of larger full size pickup truck is 10.0 in. then its height is equal to 12inches.

Eric and Nancy both had a successful year selling fish tanks for theirrespective employers, and so they were both given raises.Eric: Eric's base salary is still $1400, but now he makes a commission of$100 for each fish tank that he sells.Nancy: Nancy now gets a base salary of $500 per month, but her commissionhas stayed the same at $250 per fish tank.Eric and Nancy still want to make sure that they contribute the same amountto their total monthly income, and Nancy proposes using algebra to figureout how many fish tanks that they would each need to sell. She tells Ericthat he can calculate his monthly income by using the formula f(x) = 100x +1400. She says that she can calculate her own salary by using the functiong(x)=250x + 500.1 What does the variable x represent in Nancy's formulas?How do you know?

**Answer:**

**The variable x represents ****the number of fish tanks he/she sells****.**

**Explanation:**

Given that Eric's base salary is still $1400, but now he makes a commission of

$100 for each fish tank that he sells and Nancy now gets a base salary of $500 per month, but her commission has stayed the same at $250 per fish tank.

Eric's total income would be;

$1400 plus $100 times **the number of fish tanks he sells.**

and Nancy's total income would be;

$500 plus $250 times **the number of fish tanks she sells.**

Therefore, **the variable x represents ****the number of fish tanks he/she sells****.**

The number of fish tanks each of them sells will determine the total commission and also determines their total income.

The population of a small town in central Florida has shown a linear decline in the years 1995-2005. In 1995 the population was 24100 people. In 2005 it was 14800 people.

**Part A**:

Since the population is showing a linear decline, we can express the function P(t) as

[tex]\begin{gathered} y=mx+b \\ \text{where} \\ m\text{ is the slope} \\ b\text{ is the y-intercept} \end{gathered}[/tex]Given two points

(1995,24100), and (2005,14800)

[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \text{IF }\mleft(x_1,y_1\mright)=\mleft(1995,24100\mright),\text{ and }(x_2,y_2)=\mleft(2005,14800\mright),\text{ THEN} \\ \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{14800-24100}{2005-1995} \\ m=\frac{-9300}{10} \\ m=-930 \end{gathered}[/tex]Now that we have solved for the slope, we can now solve for the y-intercept. We will use the point (2005,14800), but using (1995,24100) will work just as well.

[tex]\begin{gathered} \text{IF }m=-930,\text{ and }(x,y)=\mleft(2005,14800\mright),\text{ THEN} \\ \\ y=mx+b \\ 14800=(-930)(2005)+b \\ 14800=-1864650+b \\ 14800+1864650=+b \\ 1879450=b \\ b=1879450 \end{gathered}[/tex]Convert the function x into a function of time t, then the the function is

[tex]P(t)=-930t+1879450[/tex]**Part 2**:

What will be the population in 2007.

Substitute t = 2007.

[tex]\begin{gathered} P(t)=-930t+1879450 \\ P(2007)=-930(2007)+1879450 \\ P(2007)=-1866510+1879450 \\ P(2007)=12940 \end{gathered}[/tex]Therefore, **in the year 2007, the population will be 12940**.

An absolute maximum point is a point where the function obtains its greatest possible value.

Similarly, an absolute minimum point is a point where the function obtains its least possible value.

**Step 1**

check the graph of g:

The y- coordinates (output) at the highest and lowest points are called the absolute maximum and absolute minimum

To locate absolute maxima and minima from a graph, we need to observe the graph to determine where the graph attains it highest and lowest points on the domain of the function

From the the diagram in the question, we can see that wa have two different triangle which are ABC and A'B'C'.

The relationship between angle ACB and angle A'C'B' is that they are corresponding angles. because they are on the same side of the line.

Corresponding angles are any pair of angles each of which is on the same side of one of two lines cut by a trasnsversal and on the same side of the transversal.

Therefore, the relationship between angle ACB and angle A'C'B' is that they are corresponding angles.

the mass of a car is 1990kg rounded to the nearest kilogram. the mass of a person is 58.7kg rounded to one decimal place. write the error interval for the combined mass, m, of the car and the person in the form _______

The **error interval** for the combined **mass** (m) of the car and the person is 2047.7 ≤ m < 2049.7

An **inequality** can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following arguments (symbols):

The **error interval** for the **mass** of car is given by:

Mass of car = 1990 ± 0.5;

Mass of car = 1990 + 0.5 = 1990.5

Mass of car = 1990 - 0.5 = 1989.5

The **error interval** for the **mass** of a person is given by:

b = 1990 ± 0.5;

b = 58.7 + 0.5 = 59.2

b = 58.7 - 0.5 = 58.2

For the value of a and b, we have:

a = 1989.5 + 58.2 = 2047.7

b = 1990.5 + 59.2 = 2049.7

Next, we would calculate the combined **mass **(m):

m = 1990 + 58.7

m = 2048.7

Now, we can write the **error interval** for the combined **mass** (m) of the car and the person as follows:
