(a) For each pool, write an expression for the amount of water in the
gool after x minutes
Two pools are being filled with water. To start, the first pool had 817 liters of water and the second pool was empty. Water is being added to the first pool at a
rate of 19 liters per minute water is being added to the second pool at a rate of 38 liters per minute.
Leta be the number of minutes water has been added.
Amount of water in the first pool (In liters) =
Amount of water in the second pool (in liters) =
(b) Write an equation to show when the two pools would have the
same amount of water
(a) Amount of water in the first pool (In liters) = (817 + 19x) liters
Amount of water in the second pool (in liters) = 39x liters
(b) An equation to show when the two pools would have the same amount of water is 817 + 19x = 38x.
Given:
For the First Pool :
Initial amount of water in the Pool = 817 liters
Water is being added to the first pool at a rate of 19 liters per minute.
Amount of water added after x minutes = 19x
So, Total amount of water after x minutes = (817 + 19x) liters
For the Second Pool:
It was empty initially.
Water is being added to the second pool at a rate of 38 liters per minute.
Amount of water added after x minutes = 38x
So, Total amount of water after x minutes = 38x liters
Now to determine an equation to show when the two pools would have the same amount of water.
817 + 19x = 38x
38x - 19x = 817
19x = 817
x = 817/19
x = 43 minutes

A funky 6-sided die with faces labeled 1, 2, 3, 4, 5, and 6 has a chance of 1/12 landing on each face and a 1/24 chance of landing on each edge. When Kira rolls the die, if it lands on a face, she records the number on top. If she lands on an edge, she records the sum of the two numbers on top. If Kira rolled the die infinitely many times and averaged the result, what is the expected value of the number recorded?
From the statement, we know that there are two possible scenarios:
A) Kira rolls the die and gets a face with a 1, 2, 3, 4, 5 or 6.
• The probability of this event is P(A) = 1/12.
,• Kira will write the number of the face in this case.
B) Kira rolls the die and gets an edge.
• The probability for this event is 1/24.
,• Kira will write the sum of the numbers that share the top edge.
,• There are multiple values for the result of the sum.
We must take into account that:
• 1 and 5 are on opposite faces,
,• 2 and 3 are on opposite faces,
,• 4 and 6 are on opposite faces.
The possible values of the sum and the forms to get it are:
0. 3, = 1 + 2 → P(B'_1) = 1/24
,1. 4, = 1 + 3 → P(B'_2) = 1/24
,2. 5, = 1 + 4 → P(B'_3) = 2/24
,3. 6, = 2 + 4 → P(B'_4) = 2/24
,4. 7, = 1 + 6 = 2 + 5 = 3 + 4 → P(B'_5) = 3/24
,5. 8, = 2 + 6 = 3 + 5 → P(B'_6) = 2/24
,6. 9, = 3 + 6 = 4 + 5 → P(B'_7) = 2/24
,7. 11, = 5 + 6 → P(B'_9) = 1/24
We have 8 possible results for the sum.
---------------------
Now, we want to know the value of the expected value of the numbers recorded by Kira.
By definition, the expected value is calculated by multiplying each of the possible outcomes by the likelihood that each outcome will occur and then summing all of those values.
The expected value of the number recorded by Kira will be:
[tex]E=\sum_{i\mathop{=}1}^6A_i\cdot P(A_i)+\sum_{i\mathop{=}1}^8B_i\cdot P(B_i)[/tex]Where:
• A_i represents the result of event A_i and P(A_i) its probability,
,• B_i represents the result of event B_i and P(B_i) its probability.
Using the data from above, we compute each of the sums.
A) For the first sum, we take into account that each event A_i has the same probability:
[tex]\sum_{i\mathop{=}1}^6A_i\cdot P(A_i)=(1+2+3+4+5+6)\cdot\frac{1}{12}=\frac{7}{4}=1.75.[/tex]B) For the second sum, we use each of the values of the sum and the probabilities of each sum:
[tex]\begin{gathered} \sum_{i\mathop{=}1}^8B_i\cdot P(B_i) \\ =3\cdot\frac{1}{24}+4\cdot\frac{1}{24}+5\cdot\frac{1}{24}+6\cdot\frac{1}{24}+7\cdot\frac{3}{24}+8\cdot\frac{2}{24}+9\cdot\frac{2}{24}+11\cdot\frac{2}{24}=\frac{95}{24}. \\ \end{gathered}[/tex]Summing the results of each sum, we get the following result for the expected value:
[tex]E=\frac{7}{4}+\frac{95}{24}=\frac{42}{24}+\frac{95}{24}=\frac{137}{24}\cong5.71.[/tex]AnswerThe expected value for the number recorded is 137/24 or approximately 5.71.

The equation of the perpendicular bisector of the line segment is y = - (1 / 2) · x - 2.
What is the equation of the perpendicular bisector of a line segment?
In this problem we find a line segment whose endpoints are known and we need to determine the equation of the line perpendicular such that the segment is partitioned into two segments of equal length. Now we present the procedure. First, determine the coordinates of the midpoint:
M(x, y) = 0.5 · (8, - 1) + 0.5 · (4, - 9)
M(x, y) = (6, - 5)
Second, determine the slope of the line segment:
m = [- 9 - (- 1)] / (4 - 8)
m = (- 8) / (- 4)
m = 2
Third, calculate the slope of the bisector:
m' = - 1 / m
m' = - 1 / 2
Fourth, determine the intercept of the bisector:
b = y - m' · x
b = - 5 - (- 1 / 2) · 6
b = - 5 + 3
b = - 2

So, we have
x 0 1 2 3 4
f(x) 1 2 4 8 16
g(x) -11 -10 -8 -4 4
Notice that the difference between the values of f(x) and g(x) is 12
This means that
g(x) = f(x) - 12
So, we have
g(x) = 2^x - 12

Which functions have a range of {ye R |-∞0 < y < ∞0}?
F(x)=x^2+7x-9
F(x)=-4x+11
F(x)=2/3X-8
F(x)=2^x+3
F(x)=-(x+1)^2-4
Answer: [tex]f(x)=-4x+11[/tex] and [tex]f(x)=\frac{2}{3}x-8[/tex]
Step-by-step explanation:
All linear functions with unrestricted domains have a range of all real numbers.
Question 1 options:
Is the relation in this set of points a function?
{(-2, 6) , (4, 5) , (3, -3) , (6, 9), (4, -4)}
State whether the statement is true of false.
1. The relation is a function.
2. An element from the domain is paired with more than one element from the range.
Answers:
FalseTrue================================================
Explanation:
Focus on (4,5) and (4,-4)
The input x = 4 leads to simultaneous outputs y = 5 and y = -4 at the same time. This is not allowed in a function. For a function to be possible, each input x must lead to exactly one y output.
Therefore, this given relation is not a function.
-----------
Domain = set of possible x inputs
Range = set of possible y outputs
The statement "An element from the domain is paired with more than one element from the range" basically means we have an x value paired with more than one y value. Therefore, this statement is true since I mentioned (4,5) and (4,-4) earlier.
Answer:
This answer is correct!
