What is meant by simplest radical form?Simply said, simplifying a radical eliminates the need for further square, cube, fourth, etc. roots to be found. This is known as expressing in the simplest radical form. In the denominator of a fraction, it also means eliminating any radicals. The top and bottom of a fraction are said to be in its simplest form if they only share the number one. For the top and bottom to remain whole numbers, you cannot divide them further. Additionally, lowest terms, or simple form, may be used. Take the fraction, as an example.The formula goes a² + b² = c², where a and b are legs of the triangle (the non hypotenuse sides), and c is the hypotenuse (the side opposite to the right angle).In this problem, we have one leg and the hypotenuse.
Let the equation be a² + b² = c²
substitute the values in the above equation, we get
5² +b² = (√21)²
25+b²=21
Move 25 to the right side
b² = -4
For x² = f(a) the solutions are [tex]$x=\sqrt{f(a)},-\sqrt{f(a)}$[/tex]
[tex]$$b=\sqrt{-4}, b=-\sqrt{-4}$$[/tex]
simplifying the above equation, we get
[tex]& \sqrt{-4}=2 i \\[/tex]

What happens to y=x when the y-intercept is changed
Answer:
When the y-intercept of a line is changed, the line will shift up or down along the y-axis. The slope of the line will remain the same, but the point at which the line crosses the y-axis will change. This means that the position of the line on the graph will change, but the overall shape of the line will stay the same. For example, if the y-intercept of the line y=x is changed from (0,0) to (0,5), the line will shift up by 5 units and will now be represented by the equation y=x+5. This will cause the line to intersect the y-axis at the point (0,5) instead of (0,0).

Graph of a linear relationship
From the graph of the linear relationship, we have the following points on the line
(0, 1) and (-4, 0)
Hence, the solutions are (0, 1) and (-4, 0)
Increasing or decreasingOn the graph, we can see that as x increases, the y value increases
This means that the graph is an increasing graph

The composition of the two functions g of x and f of x is:
(g o f)(x) = 3x² - 15x + 1
How to find the composition of functions?Here we have three known functions, these are:
f(x) = x² - 5xg(x) = 3x + 1h(x)= (x - 1)/xAnd we want to find the composition of functions:
(g o f)(x)
That means that we need to evaluate the function g(x) on f(x), so we will get:
(g o f)(x) = g( f(x))
Then we will get:
g( f(x)) = 3*f(x) + 1
Now we can replace the actual function f(x) there, so we will get:
g( f(x)) = 3*f(x) + 1
g( f(x)) = 3*(x² - 5x) + 1
Now we can simplify that:
g( f(x)) = 3*(x² - 5x) + 1
g( f(x)) = 3*x² - 3*5x + 1
g( f(x)) = 3x² - 15x + 1

Container A has 300 liters of water, and is being filled at a rate of 6 liters per minute. Container B has 900 liters of water, and is being drained at 2 liters per minute. How many minutes, m, will it take for the two containers to have the same amount of water?
It will take 150 minutes for the two containers to have the same amount of water.
To find the number of minutes it will take for the two containers to have the same amount of water, we need to use the following formula:
m = |A - B| / (a - b)
where m is the number of minutes, A is the initial amount of water in Container A, B is the initial amount of water in Container B, a is the rate at which water is being added to Container A, and b is the rate at which water is being drained from Container B.
In this case, the initial amount of water in Container A is 300 liters, the initial amount of water in Container B is 900 liters, the rate at which water is being added to Container A is 6 liters per minute, and the rate at which water is being drained from Container B is 2 liters per minute. Substituting these values into the formula, we get:
m = |300 - 900| / (6 - 2)
m = |-600| / 4
m = 600 / 4
m = 150 minutes
Therefore, it will take 150 minutes for the two containers to have the same amount of water.

y ∈ [-5, 3), the lowest point is included as part of graph, the highest value is excluded as open circle..This is a function as it passes the vertical line test.

y ∈ [-1, 5], both ends included as part of the graph.This is not a function as it fails the vertical line test.
Answer:

Range: [-5, 3)
26) Domain: [-3, 7]
Range: [-1, 5]

An open circle indicates the value is not included in the interval.A closed circle indicates the value is included in the interval.An arrow shows that the function continues indefinitely in that direction.Interval notation
( or ) : Use parentheses to indicate that the endpoint is excluded.[ or ] : Use square brackets to indicate that the endpoint is included.The domain is the set of all possible input values (x-values).
The range is the set of all possible output values (y-values).
Question 25From inspection of the graph, the endpoints of the continuous curve are:
(-6, -3) and (6, 3)As the endpoints are open circles, the values are excluded from the domain and range.
Therefore, the domain in interval notation is:
Domain: (-6, 6)The smallest y-value is y = -5 and the greatest y-value is y = 3.
Therefore, the range in interval notation is:
Range: [-5, 3)Question 26The graph is a conic section (ellipse) and therefore it is not a function.
The smallest x-value is x = -3 and the greatest x-value is x = 7.
The smallest y-value is y = -1 and the greatest y-value is y = 5.
Therefore, the domain and range in interval notation are:

Also provided below is the ANOVA output for comparing average hours across educational attainment categories. (a) Write the hypotheses for testing for a difference between the average number of hours spent on child care across educational attainment levels. (b) What is the conclusion of the hypothesis test?

What is a typical value?In mathematics, the middle value—which is determined by dividing the sum of each of the values by the total number of values—is the approximate amount in a collection of numbers. To determine the median of a collection of data, add all of the values and divide the result by the total number of values.
Briefing:a). The study's goal is to determine if there is discernible variation in the typical quantity of time spent on childcare services across levels of educational achievement.
Null hypothesis, H₀ = μ₁= μ₂ = μ₃=μ₄= μ₅
(The average quantity of time spent on child rearing across educational levels does not change much.)
Alternative hypothesis, Hₐ : At least two μ₁s are unequal.
(The mean number of hours on child care varies significantly depending on the degree of education).
b). Let the level of significance be, ∝ = 0.05
Decision rule: Reject H₀ if p-value ≤ 0.05
The result statistic F has a value of 1.26 and a p-value of 0.2846 based on the provided ANOVA table. Keep in mind that the p-value exceeds the 5% expected level of significance. Therefore, don't reject H₀.
