The standard form of the equation of a parabola is x = y2 + 6y + 1. What is the vertex form of the equation? O A. x = (y + 3)2 - 8 O B. x = (y + 6)2-11 O C. x = (y + 6)2-35 O D. x = (y + 3)2-5​

Answers

Answer:

A

Step-by-step explanation:

Given

x = y² + 6y + 1

To complete the square

add/subtract ( half the coefficient of the y- term )² to y² + 6y

x = y² + 2(3)y + 9 - 9 + 1

  = (y + 3)² - 8

The vertex form of the equation of a parabola is,

⇒ x = (y + 3)² - 8

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The standard form of the equation of a parabola is,

⇒ x = y² + 6y + 1.

Now, We can simplify as;

⇒ x = y² + 6y + 1

⇒ x = y² + 6y + 9 - 9 + 1

⇒ x = (y + 3)² - 8

Thus, The vertex form of the equation of a parabola is,

⇒ x = (y + 3)² - 8

George is reading a book.On Monday he read 1/3 of the book. On Tuesday he reads three-tenths of the remaining pages. He has 35 pages left to read. How many pages are in the book

Answers

Answer:

Step-by-step explanation:

m=p/3

t=(3/10)(1-1/3)

t=(3/10)(2/3)=p/5

p-p/3-p/5=35

(15p-5p-3p)/15=35

7p/15=35

7p=525

p=75

So the book has 75 pages.

The list below shows the tips earned by Cody while working at Olive Garden. $20, $45, $30.50, $46, $50 What is the mean of the tips earned by Cody?

Answers

Answer:

$38.30

Step-by-step explanation:

Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

Sum of the numbers = $20 + $45 + $30.50 + $46 + $50 = $191.50

Total number = 5

Mean = $191.50 / 5 = $38.30

Jordyn is weighing ingredients on a kitchen scale. The bowls weighs 1 1 2pounds. He adds several scoops of flour. The total weigh of the bowl and flour is 3 pounds. Each cup of flour weighs 1 4pounds. Solve the equation 1 1 2+ 1 4c = 3 to see how many cups of flour he adds.

Answers

Answer:

6cups

Step-by-step explanation:

Given the equation

1 1/2 + 1/4c=3

We are to find the value of c

3/2 + c/4 = 3

c/4 = 3 - 3/2

c/4 = (6-3)/2

c/4 =3/2

Cross multiply

2c = 3×4

2c = 12

c =6

Hence he adds 6cups of flour

20 out of 800 products were found to be defective. At the same rate, how many defective parts will be found in 40,000 products? There would be Blank 1 defective parts out of 40000.

Answers

Answer: 1,000 products

Step-by-step explanation:

If 20 out of 800 products are found to be defective, the percentage of defective products would be:

= 20 / 800

= 2.5%

At this same rate of 2.5%, if there are 40,000 products instead of 800, the number of defective products would be:

= 2.5% * 40,000

= 1,000 products

Which statement is true about a trend line?

Answers

Answer:

Its b

Step-by-step explanation:

I did the test...

The correct statement about a trend line is: A trend line and a regression line are equivalent terms.

A trend line and a regression line are NOT equivalent terms. They refer to different concepts in data analysis.

1. Trend Line:

A trend line, also known as a line of best fit, is used to represent the general direction or pattern of a dataset. It is a straight line that fits through the data points in a scatter plot to show the overall trend in the data. The primary purpose of a trend line is to identify the underlying pattern or tendency of the data points. Trend lines can be linear or nonlinear, depending on the nature of the data.

In simple terms, a trend line helps us visualize whether the data is increasing, decreasing, or following a specific pattern over time or across a range of values.

2. Regression Line:

A regression line is a specific type of trend line used in linear regression analysis. Linear regression is a statistical method that examines the relationship between two or more variables to predict an outcome. It finds the "best-fit" straight line that minimizes the sum of the squared differences between the actual data points and the predicted values.

The regression line represents the relationship between the independent variable(s) (usually denoted as 'X') and the dependent variable (usually denoted as 'Y'). It provides an equation of the form Y = a + bX, where 'a' is the y-intercept and 'b' is the slope of the line. The regression line serves as a predictive model to estimate the value of the dependent variable based on the values of the independent variable(s).

- A trend line represents the general direction or pattern of a dataset.

- A regression line is a specific type of trend line used in linear regression to predict outcomes based on the relationship between variables.

Therefore, the correct statement is: A trend line and a regression line are NOT equivalent terms.

Viral genomes do not contain all the genes needed to produce all proteins necessary for DNA replication, RNA transcription, and protein translation; instead the viruses force bacterial proteins and enzymes to express phage genes instead of bacterial genes.Phage are very adaptable, and their behavior depends on whether conditions are favorable or unfavorable for making more phage.When bacteria are plentiful (favorable conditions), viral DNA within the bacteria remains separate from the bacterial chromosome, and the virus forces the bacteria to make more virus. When the amount of virus becomes too much for the cell to hold, the membrane ruptures, and viruses are released to infect surrounding bacteria. This is known as the lytic cycle.When bacteria are scarce (unfavorable conditions), the viral DNA within the bacteria becomes integrated into the bacterial chromosome. The bacteria survive and are still able to reproduce; viral DNA is transmitted to daughter cells when the bacteria reproduces. This is known as the lysogenic cycle.As you just read, phage depend on bacteria to reproduce. Phage can be maintained by infecting a culture of bacteria with a strain of phage, and then plating the bacteria on an agar plate to grow.Suppose that you isolate two mutant strains of phage - one strain cannot enter the lytic cycle and the other strain cannot enter the lysogenic cycle. You also grow wild-type phage as a control. You see three different phenotypes:A plate with no missing bacteria- the lawn of bacteria is intactA plate with spots/circles (called plaques) where there are absolutely no bacteria in the circlesA plate with spots/circles (called plaques) where there are some bacteria in the center of the circles.Based on what you know about what happens in each cycle, match the plating results with the identity of the strain.Drag each plate into the correct category.
