Making Vi the subject of formula gives the following expression: Vi = √(Vf² - 2aX).

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In this exercise, you're required to describe the steps that should be taken to rearrange and make Vi the subject of formula. Therefore, the appropriate and required steps are listed as follows:

Vf² = Vi² + 2aX

Subtracting 2aX from both sides of the equation, we have:

Vf² - 2aX = Vi² + 2aX - 2aX

Vi² = Vf² - 2aX

Taking the square root of both sides, we have:

Vi² = Vf² - 2aX

Vi = √(Vf² - 2aX)

Answer:

1) 4x-1/2 = x + 7

Answer : x=5/2

2) 3x + 2 = 2x+13/3

Answer: x=7/3

Step-by-step explanation:

1) 4x-1/2 = x + 7

Solution

Let's solve your equation step-by-step.

4x−1/2=x+7

Step 1: Simplify both sides of the equation.

4x+−1/2=x+7

Step 2: Subtract x from both sides.

4x+−1/2−x=x+7−x

3x+−1/2=7

Step 3: Add 1/2 to both sides.

3x+−1/2+1/2=7+1/2

3x=15/2

Step 4: Divide both sides by 3.

3x/3=15/2/3

x=5/2

2) 3x + 2 = 2x+13/3

Solution

Let's solve your equation step-by-step.

3x+2=2x+13/3

Step 1: Subtract 2x from both sides.

3x+2−2x=2x+13/3−2x

x+2=13/3

Step 2: Subtract 2 from both sides.

x+2−2=13/3−2

The length of the side AD after undergoing a dilation using a scale factor of 1.5 as required in the task content is; 16.5.

To evaluate the length of side AD prior to the transformation which involves a dilation.

The distance between two points is given by;

D = √((y2 - y1)² + (x2 x1)²)

It follows that the lengths of the pre-image can be determined as follows;

AD = √((-5-6)² + (5 -5)²)

AD = √(-11)² + 0²

AD = √121

AD = 11

Ultimately, upon undergoing a dilation using a scale factor of 1.5, the length of AD becomes; 11 × 1.5

Hence, AD = 16.5.

Answer:

Full-time worker minimum monthly income = US$ 7,846.40

Part-time worker minimum monthly income = US$ 7,846.40

Full-time worker hourly wage = US$ 49.04

Part-time worker hourly wage = US$ 98.08

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Monthly costs of a 2-adult and 3-children family in the Modesto metro area = US$ 7,846

Full-time worker = 4 weeks of 40-hour per month

Part-time worker = 2 weeks of 40-hour per month

2. Let's calculate the minimum monthly income and hourly wage per worker

Full-time worker hourly wage = Monthly costs/160

Part-time worker hourly wage = Monthly costs/80

Full-time worker hourly wage = 7,846/160

Part-time worker hourly wage = 7,846/80

Full-time worker hourly wage = US$ 49.04

Part-time worker hourly wage = US$ 98.08

Full-time worker minimum monthly income = Hourly wage * 160

Part-time worker minimum monthly income = Hourly wage * 80

Full-time worker minimum monthly income = US$ 7,846.40

Part-time worker minimum monthly income = US$ 7,846.40

The equation for a​ two-week trip of 500 miles' rental cost is Total rent cost = 2x + 500y

Information about the problem:

To solve this problem, we have to state the equation using the information of the problem:

Car rent for 2 weeks = 2x

Car rent for 500 miles = 500y

Total rent cost = 2x + 500y

Example:

Car rent per week = $280/ week

Car rent per miles = $0.75/ mile

Total rent cost = (2 weeks * $280/ week) + (500 miles * $0.75/ mile)

Total rent cost = $560 + $375

Total rent cost = $935

Answer:

0.16 for one egg. 1.90 for a dozen.

Step-by-step explanation:

For 24 eggs it is 3.79 dollars, so to find the price of one egg we just divide 3.79 by 24, which is 0.16.

There are 12 eggs in a dozen, and it's 3.79 for 24 eggs, so I can divide it by 2 to get to a dozen, so 3.79/2 = 1.90

Answer:

.16 per egg

1.90 for a dozen

Step-by-step explanation:

Take the total cost and divide by the number of eggs to find the cost for one egg

3.79/24 =.157916667

Since this is money we round to the nearest cent

.16

The cost per one egg is .16 or 16 cents

Multiply this by 12 to get the cost of 12 eggs

3.79/24  * 12 =1.895

This will round to 1.90

(Do not use the rounded answer to find the cost of a dozen eggs, because it will be higher.  We need to use the exact answer when calculating)

Using the midpoint formula, the coordinates of point U are: (9, 2).

The midpoint formula is: M[(x2 + x1)/2, (y2 + y1)/2]

Given the following:

Midpoint of TU is at: M(5,5)

Point T is at (1, 8), therefore, let:

M(5,5) = (x, y)

T(1, 8) = (x1, y1)

U(?, ?) = (x2, y2)

Plug in the values

M(5, 5) = [(x2 + 1)/2, (y2 + 8)/2]

5 = (x2 + 1)/2

10 = x2 + 1

10 - 1 = x2

9 = x2

x2 = 9

5 = (y2 + 8)/2

10 = y2 + 8

10 - 8 = y2

2 = y2

y2 = 2

The value of v in the equation is as follows:

Solve two thirds times v plus 6 equals one third times v minus 2.

Therefore, the equation is as follows:

2 / 3 × v + 6  = 1 / 3 × v - 2

2 / 3v + 6 = 1 / 3 v - 2

add 2 to both sides of the equation

2 / 3v + 6 = 1 / 3 v - 2

2 / 3v + 6 + 2 = 1 / 3 v - 2 + 2

2 / 3v + 8 = 1 / 3 v

subtract 2 / 3 v from both sides

2 / 3v + 8 = 1 / 3 v

2 / 3v - 2 / 3 v + 8 = 1 / 3 v  - 2 / 3 v

8 = 1v - 2v / 3

What is scaling ?

It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.

It is given that, leslie drew a scale drawing of soccer field. in real life, the soccer field is 99 meters long. it is 187 millimeters long in the drawing.

Now, corelating the scale given which means for 99m of actual side of the soccer field scale is 187 mm. Now, the scaling factor is calculated by dividing 99 m with 187 mm.

99 m actual size of soccer field = 187 mm in drawing

1 m actual size of soccer field = (187/ 99) mm in drawing = 1.89 mm in drawing

Step-by-step explanation:

To find how much Ben's rent is per month, we first have to find how much Ben spends on rent annually (every year). We can do this by multiplying his annual salary by the percentage spent on rent.  

22000 · 0.15 = 3300

Now that we know Ben spends 3300 on rent a year, we can divide that amount by 12 (the number of months in a year) to find out how much his rent is per month.

3300 / 12 = 275

We need to know about arranging numbers in an ascending order to solve the problem. The numbers arranged in ascending order is 73156, 75136, 84945, 85105, 91504, 93405, 94054.

There are two ways to arrange numbers- ascending order and descending order. Ascending order is the method of arranging numbers from lowest to highest and descending order is the method of arranging numbers from highest to lowest. To arrange 5-digit numbers in an ascending order we will need to know how to find the lowest number first. For 5-digit number we will be checking the first two digits of the number first that will tell us the numbers in tens of thousands, after we find the smallest tens of thousand in the list we follow the same process to  find the consecutive numbers. If two numbers have same first two digits then we chcek the hundreds and so on. For the given question the numbers arranged in ascending order will be

73156, 75136, 84945, 85105, 91504, 93405, 94054

Therefore we found the ascending order arrangement of the 5-digit numbers which is 73156, 75136, 84945, 85105, 91504, 93405, 94054.

As per standard deviation criteria for outliers,  26.3 mm is the maximum thickness for which the statistician would need to examine the machine's configuration.

What is the standard deviation?

The numbers that do not lie within two standard deviations of the mean are considered outliers by the two-standard deviation criteria for outliers.

If the mean is 23.5 mm and the standard deviation is 1.4 mm

Next, the highest thickness needs to be checked: mean Plus 2 (standard deviation)

= 23.5 + (2 *1.4)
