Answer to this equation , simplified
If the value of a = 5 and c = √21 then the value of b = 2i, b = -2i.
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]
[tex]& -\sqrt{-4}=-2 i \\[/tex]
b = 2i, b = -2i
Therefore, the value of b = 2i, b = -2i.

Domain - the set of possible x-coordinates of a function.
Range - the set of possible y-coordinates of a function.
Question 25
Domain is:
x ∈ (- 6, 6), both ends excluded as open circles.Range is:
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.
Question 26Domain is:
x ∈ [- 3, 7], both ends included as part of the graph.Range is:
y ∈ [-1, 5], both ends included as part of the graph.This is not a function as it fails the vertical line test.
Answer:
25) Domain: (-6, 6)
Range: [-5, 3)
26) Domain: [-3, 7]
Range: [-1, 5]
Step-by-step explanation:
Definitions
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:

He must decide whether to invest his savings in Big Sky Bank which offers 20% compounded semi-annually or Valley Bank which offers 8% compounded quarterly. What compounded amount would he earn he chooses to invest his savings in Big Sky Bank? What compounded amount would he earn if he chooses to invest his savings in Valley Bank?
The compounded amount earned in Big Sky Bank is $40,365.00.
The compounded amount earned in Valley Bank is $13,248.24.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
P = 10% of 60,000
P = 6000
t = 10 years
Big sky Bank:
r = 20%
n = 2 (semiannually)
A = 6000 [tex](1 + 0.1)^{20}[/tex]
A = 6000 x [tex]1.01^{20}[/tex]
A = $40,365.00
Valley Bank:
r = 8%
n = 4 (quarterly)
A = 6000 [tex](1 + 0.02)^{40}[/tex]
A = 6000 x [tex]1.02^{40}[/tex]
A = $13,248.24
Thus,
Big Sky Bank compounded amount is $40,365.00.
Valley Bank compounded amount is $13,248.24.

Mr. Rooks' bank pays 4-% interest per year. He has $17,000 in the bank. How much interest would he receive in 3 years?
Mr. Rooks would receive $2,040 in interest in 3 years.
The interest rate is given as 4%, which means that for every $100 Mr. Rooks has in the bank, he will receive $4 in interest per year.
To find the total interest Mr. Rooks will receive in 3 years, we need to multiply the annual interest rate by the number of years, and then multiply that result by the amount of money Mr. Rooks has in the bank.
In this case, the calculation would be as follows:
Annual interest rate × number of years × amount in the bank = total interest
(4 / 100) × 3 × $17,000 = $2,040
Therefore, Mr. Rooks would receive $2,040 in interest in 3 years.

In the data set below, what is the value of the 1st quartile?
(6,7,8,9,10,12,14)
Answer: 7 is the first quartile
Step-by-step explanation:
method to find quartile
Order your data set from lowest to highest values
Find the median. This is the second quartile Q2.
At Q2 split the ordered data set into two halves.
The lower quartile Q1 is the median of the lower half of the data.
The upper quartile Q3 is the median of the upper half of the data.
If the size of the data set is odd, do not include the median when finding the first and third quartiles.
If the size of the data set is even, the median is the average of the middle 2 values in the data set. Add those 2 values, and then divide by 2. The median splits the data set into lower and upper halves and is the value of the second quartile Q2.

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).

Step-by-step explanation:
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.
