The equation for the axis of symmetry for the given parabolic graph is found as: x = 3.
Explain about the parabolic curve:A parabola is the graph of a quadratic function and features a vertical line passing through its vertex as its axis of symmetry.
A parabola, a U-shaped curve, is the shape of a quadratic function's graph. The graph's vertex, which is an extreme point, is one of its key characteristics. The vertex, or lowest point on the graph or minimal value of the quadratic function, is where the parabola will open up. The vertex is the highest location on the graph or the maximum value if the parabola opens downward. The vertex is a pivotal location on the graph in both scenarios.The graph is also symmetric, with the axis of symmetry being a vertical line that passes through the vertex.
Thus, the equation for the axis of symmetry for the given parabolic graph is found as: x = 3.

Which point lies on the circle x^2+y^2=100
A (0,-100)
B (10,-10)
C (25,75)
Answers
Answer:
NOT a single ordered pair satisfies the equation.
Step-by-step explanation:
Given the equation
\(x^2+y^2=100\)
Let us substitute all the given ordered pairs to find which ordered pair satisfies the equation.
For (0, -100)
\(x^2+y^2=100\)
substitute x=0 and y=-100
\(0^2+\left(-100\right)^2=100\)
\(10000=100\)
FALSE
Thus, the ordered pair (0, -100) does NOT satisfy the equation.
For (10, -10)
\(x^2+y^2=100\)
substitute x=10 and y=-10
\(10^2+\left(-10\right)^2=100\)
\(200=100\)
FALSE
Thus, the ordered pair (10, -10) does NOT satisfy the equation.
For (25, 75)
\(x^2+y^2=100\)
substitute x=25 and y=75
\(25^2+\left(75\right)^2=100\)
\(6250=100\)
FALSE
Thus, the ordered pair (25, 75) does NOT satisfy the equation.
Therefore, NOT a single ordered pair satisfies the equation.

Speeds of Trains A passenger train and a freight train leave a town at the same time and travel in opposite directions. Their speeds are 60 mph and 75 mph, respectively. How long will it take for the trains to be 297 miles apart?
Answers
The time it takes for the trains to be 297 miles apart is 297 miles / 135 mph = 2.2 hours.
To calculate the time it takes for the trains to be 297 miles apart, we can use the formula: time = distance / relative speed. Since the trains are moving in opposite directions, their relative speed is the sum of their speeds.
In this case, the relative speed of the passenger train and the freight train is 60 mph + 75 mph = 135 mph. Therefore, the time it takes for the trains to be 297 miles apart is 297 miles / 135 mph = 2.2 hours.
However, since time is typically measured in whole numbers of hours, we round up the decimal value to the nearest whole number. Therefore, it will take approximately 3 hours for the trains to be 297 miles apart.
It's important to note that this calculation assumes that the trains maintain a constant speed throughout the entire journey and that there are no stops or delays along the way.
Real-world factors such as acceleration, deceleration, and potential stops at stations would affect the actual time it takes for the trains to be 297 miles apart.

The corresponding equation is 4q + 3p = 22.
What is the slope of a line ?
The ratio of the change in the y coordinate to the change in the x coordinate is known as a line's b in mathematics.
Y and X, respectively, stand for the net change in the y-coordinate and the net change in the x-coordinate. Locate two locations along the chosen line and find their coordinates.
Find the y-coordinate difference between these two places (rise). Find the difference between the x-coordinates of these two points (run). Subtract the difference in y-coordinates from the difference in x-coordinates (rise/run or slope).
The slope is defined as the relationship between the rise, or vertical change, between two points and the change, or horizontal change, between the same two points and can be represented as an equation.
Given that, coordinates are (p, 1/2) and (-8, q), slope is 3/4.
m = (y2 - y1)/(x2 - x1)
34 = (q - 1/2)/-8 - p
-24 - 3p = 4q - 2
4q + 3p = 22
The corresponding equation is 4q + 3p = 22.

Write your answer in the space below. 5. Is the bottom shelf parallel to the middle shelf? Explain. Write your answer in the space below.
Answers
Answer:
Step-by-step explanation:
1). Since, m∠1 + m∠2 = 180° [Supplementary angles]
If m∠2 = 120°
m∠1 + 120° = 180°
m∠1 = 180° - 120°
m∠1 = 60°
2). If a transversal intersects two parallel lines on the top and middle,
∠1 and ∠5 will be corresponding angles.
3). Since, m∠1 = m∠5 = 60° (Corresponding angles)
Therefore, both the lines on top and middle will be parallel.
4). Since, m∠9 + m∠11 = 180° [Supplementary angles]
If m∠11 = 120°
m∠9 + 120° = 180°
m∠9 = 60°
Since, m∠1 = m∠9 = 60° [Corresponding angles]
Therefore, both the lines on the top and bottom shelves will be parallel.
5). Since, m∠5 = m∠9 = 60° [Corresponding angles]
Therefore, middle and bottom shelves will be parallel.
Explain how the U. S entertainment industry changed during the 1930s
Answers
The 1930s was a period of significant change in the U.S. entertainment industry, with the emergence of new technologies and the development of new forms of media. Here are some of the key changes that took place:
The rise of sound films: The introduction of synchronized sound in films in the late 1920s revolutionized the movie industry, and by the 1930s, "talkies" had replaced silent films as the dominant form of cinema. This led to a surge in demand for new films and a boom in the movie theater industry.The growth of radio: Radio broadcasting became increasingly popular in the 1930s, with programs ranging from news and current affairs to drama, comedy, and music. Radio provided a new form of entertainment and also became an important platform for advertising, with many companies sponsoring radio programs to reach a wider audience.The impact of the Great Depression: The economic downturn of the Great Depression had a significant impact on the entertainment industry, with many people struggling to afford tickets to movies and shows. As a result, many producers focused on creating more affordable forms of entertainment, such as low-budget films and radio programs.The emergence of new genres: In response to changing audience preferences, new genres of entertainment emerged in the 1930s. One of the most popular was the screwball comedy, a lighthearted and fast-paced form of comedy that often featured romantic storylines. The decade also saw the rise of gangster films, musicals, and horror movies.The impact of censorship: In 1930, the Motion Picture Production Code was introduced, which established strict guidelines for the content of movies to ensure that they were "wholesome" and "morally uplifting." This had a significant impact on the content of films and limited the freedom of filmmakers to explore controversial or taboo subjects.Overall, the 1930s was a period of significant change in the U.S. entertainment industry, with the rise of new technologies and the emergence of new forms of media leading to the development of new genres and changing audience preferences.

Birth weight of infants at a local hospital have a Normal distribution with a mean of 110 oz and a standard deviation of 15oz. A. What is the proportion of infants with birth weights between 110oz and 125oz ? B. What is the nroportion of infants with birth weights between 88oz and 98oz ?
Answers
A. Approximately 34.13% of infants have birth weights between 110 oz and 125 oz.
B. Approximately 14.11% of infants have birth weights between 88 oz and 98 oz.
To find the proportion of infants with birth weights within certain ranges, we need to calculate the area under the normal distribution curve using the z-scores.
A. Birth weights between 110 oz and 125 oz:
To find the proportion of infants with birth weights between 110 oz and 125 oz, we need to calculate the z-scores corresponding to these values and then find the area under the normal curve between those z-scores.
Z1 = (110 - 110) / 15 = 0
Z2 = (125 - 110) / 15 = 1
Using a standard normal distribution table or a calculator, we can find the area under the curve between z = 0 and z = 1, which represents the proportion of infants with birth weights between 110 oz and 125 oz.
P(110 oz ≤ X ≤ 125 oz) = P(0 ≤ Z ≤ 1)
From the standard normal distribution table, the area corresponding to z = 1 is approximately 0.8413, and the area corresponding to z = 0 is 0.5.
P(0 ≤ Z ≤ 1) = 0.8413 - 0.5 = 0.3413
Therefore, approximately 34.13% of infants have birth weights between 110 oz and 125 oz.
B. Birth weights between 88 oz and 98 oz:
Similarly, we can find the proportion of infants with birth weights between 88 oz and 98 oz using the same approach.
Z1 = (88 - 110) / 15 = -1.47
Z2 = (98 - 110) / 15 = -0.8
P(88 oz ≤ X ≤ 98 oz) = P(-1.47 ≤ Z ≤ -0.8)
From the standard normal distribution table, the area corresponding to z = -0.8 is approximately 0.2119, and the area corresponding to z = -1.47 is approximately 0.0708.
P(-1.47 ≤ Z ≤ -0.8) = 0.2119 - 0.0708 = 0.1411
Therefore, approximately 14.11% of infants have birth weights between 88 oz and 98 oz.

What are supplementary angles?Supplementary angles are those angles that sum up to 180 degrees. For example, angle 110° and angle 70° are supplementary angles because the sum of 110° and 70° is equal to 180°.
Given ∠EAF and ∠BAF are supplementary angles
Since sum of two supplementary angles = 180
Thus,
∠EAF + ∠BAF = 180
2x + 4x = 180
6x = 180

Answers
(a) The function f(x, y) does not have a limit at (0,0). (b) No information is provided to determine the limit for f2(x, y).
(a) For the function f(x, y) = 5ry²/(3x² + y²), we can analyze the behavior as (x, y) approaches (0,0). Since the denominator 3x² + y² becomes zero as (x, y) approaches (0,0), we cannot directly evaluate the function at this point. However, by considering the parabola z = -y², we can observe that the function does not approach a specific value and thus does not have a limit at (0,0).
(b) The function f2(x, y) = Vel + Vsin(y) is not well-defined as no information or context is provided for the variables Vel, V, and U. Without this information, it is not possible to determine the limit of the function at (0,0) or any other point.
Therefore, for (a), the function f(x, y) does not have a limit at (0,0), and for (b), no information is given to determine the limit for f2(x, y).
