Answer:
What is the equation of the graphed line written in standard form?" has four options: 2x + 3y = -6, 2x + 3y = 6, y=-2/3x-2, and y= 2/3x-2. The standard form of a linear equation is Ax + By = C, where A, B, and C are constants. In this case, the first two options, 2x + 3y = -6 and 2x + 3y = 6 are already in standard form. The last two options, y=-2/3x-2 and y= 2/3x-2 are not in standard form. However, without additional information such as a graph or coordinates of points on the line, it is not possible to determine which of these options is the correct equation for the graphed line.

After working for the government for years, Geordi goes to work for an engineering firm that lobbies for more government funding. This is an example of
Answers
Geordi's transition from working for the government to joining an engineering firm that advocates for increased government funding is an example of the "revolving door" phenomenon.
The "revolving door" refers to the movement of individuals between government positions and jobs in the private sector that are closely related to government affairs. In this case, Geordi's shift from a government job to an engineering firm involved in lobbying for government funding reflects this phenomenon.
The revolving door can raise concerns about potential conflicts of interest and the influence of special interest groups on government policies and decisions. While Geordi's move is not inherently unethical or illegal, it highlights the close relationship between government entities and private industries, and the potential for individuals to leverage their expertise and connections for personal or corporate gain.

Select the correct answer. What is the complete factorization of x2 + 2x − 63? A. (x + 21)(x − 3) B. (x − 9)(x + 7) C. (x + 9)(x − 7) D. (x − 21)(x + 3)
Answers
Answer:
C is correct
Step-by-step explanation:
x² + 2x - 63
= x² +9x - 7x - 63
= x(x+9)-7(x+9)
= (x + 9)(x - 7)
∴ C is correct
Step by step using “complete the Square” method
x^2 + 2x -63 = 0
Isolate variables, add 63 to both sides
x^2 +2x = 63
Find 1/2 of x and square it a= 1^2 = 1
Add 1 to both sides of the equation
x^2 + 2x +1 = 63 + 1
Simplify
x^2 + 2x +1 = 64
Now you can factor both sides
( x + 1) ^2 on the left - explanation
( x + 1) (x + 1) distributed = x^2 + 2x +1
Now take square root of both sides
√ (x + 1)^2 = √64
x + 1 = +- 8
Subtract 1 from both sides
x = -1 +- 8
So
x = -1 + 8
x = 7 or ( x - 7)
x = -1 -8
x = -9 or ( x + 9)
So C. Is your correct answer

On October 4, 2015. the BBC world news ran an article about a sudden increase in shark attacks in Australia. The first couple of statements read: "lt has been a nasty year for shark attacks in Australia. There have been two fatalities recorded so far, 29 attacks and 18 iniuries.

Answers
0.0378 shark attacks per two-day period on average happened in 2015.
To determine how many shark attacks occurred on average during a two-day period in 2015, we must estimate the average daily rate of shark attacks in Australia using historical data..
The average daily rate for shark attacks over the past century, which totaled 840, is as follows:
0.023 attacks each day, or 840 attacks over 365 years. We may forecast the rate for 2015 as follows using data from the previous few years and the presumption that the frequency of shark attacks is virtually consistent over time:
Attacks from 2012 to 2014: (3 * 365) days / (22 + 14 + 23) attacks = 0.0189
µv = 2 * 0.0189 = 0.0378
Hence, 0.0378 shark attacks per two-day period on average happened in 2015.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Multiply by x on both sides of the equation , we get
x² - 1 = x
Subtracting x on both sides of the equation , we get

Let's call the total pay for Joe "P". We know that Joe makes a base pay of $200 a week, so we can write the first part of the expression as:
Describe expression using an example.
Term is defined as a constant, a single variable, or a mixture of variables and constants multiplied or divided. Algebra Expression Example: 3x + 9, 5x + 10…
P = 200
In addition to the base pay, Joe makes $3 for each magazine subscription he sells. We can use the variable "m" to represent the number of magazine subscriptions sold, so the second part of the expression can be written as:
P = 200 + 3m
Putting these two expressions together, we get the final expression that models the situation:
P = 200 + 3m
This expression says that Joe's total pay is equal to his base pay of $200 plus $3 for each magazine subscription he sells, where "m" represents the number of magazine subscriptions sold.

Label your line 'Supply'. (Use the "Esc" key after you have placed your last point to exit the drawing tool.) The equilibrium quantity of ventilators sold is units. Carefully follow the instructions above and only draw the required pbjects.
Answers
In a competitive market, we need to graph the market demand and supply curves and determine the equilibrium quantity. The equilibrium quantity represents the quantity at which the demand and supply curves intersect.
To sketch the supply and demand curves, we first need to gather information on the market demand and supply. The demand curve represents the quantity of ventilators that the four hospitals are willing to purchase at different prices, while the supply curve represents the quantity of ventilators that the four producers are willing to sell at different prices.
Using the multipoint drawing tool, we can plot the market demand curve based on the data provided for the hospitals. Label this line as 'Demand'. Next, using the same tool, we can plot the market supply curve based on the data provided for the producers. Label this line as 'Supply'.
The equilibrium quantity is determined at the point where the demand and supply curves intersect. It represents the quantity of ventilators that will be sold in the market. To find this point, we identify the quantity at which the demand and supply curves meet on the graph.
By following the instructions and accurately plotting the demand and supply curves, we can determine the equilibrium quantity of ventilators sold in the market.

Answers
Answer:
1 ≥ t ≤ 3
Step-by-step explanation:
Given
h(t) = -16t² + 64t + 4
Required
Determine the interval which the bar is at a height greater than or equal to 52ft
This implies that
h(t) ≥ 52
Substitute -16t² + 64t + 4 for h(t)
-16t² + 64t + 4 ≥ 52
Collect like terms
-16t² + 64t + 4 - 52 ≥ 0
-16t² + 64t - 48 ≥ 0
Divide through by 16
-t² + 4t - 3 ≥ 0
Multiply through by -1
t² - 4t + 3 ≤ 0
t² - 3t - t + 3 ≤ 0
t(t - 3) -1(t - 3) ≤ 0
