The depth of water changes at a rate of -13/72π feet per minute when the water is 2 feet high.
To begin, we must use the formula for the volume of a cone, which is given as:
V = 1/3πr2hwhere V represents the volume, π represents the constant pi, r represents the radius, and h represents the height.
Substituting the given values into the formula, we get:
V = 1/3π (6 ft)2(14 ft)V = 1/3π (36 ft2) (14 ft)V = 1/3π (504 ft3)V = 168π ft^3
Now, we must determine the rate at which water is leaking. It is given that the cone leaks water at a rate of 13 cubic feet per minute. This implies that the volume of the water reduces by 13 cubic feet every minute. Therefore, the rate of change of the volume of water is -13 cubic feet per minute. Here, the negative sign indicates a decrease in the volume of water.
Now, we must find how fast the depth of water changes when the water is 2 feet high. Let d represent the depth of water. Then, the volume of water is given as:
V = 1/3πr^2d
We know that when d = 2 ft, V = 1/3π(6 ft)2(2 ft)
V = 8π ft^3
Now, we must determine how fast the volume of water is changing with respect to time when d = 2 ft. We differentiate the expression for V with respect to time to get:
dV/dt = (d/dt)[1/3πr2d]
dV/dt = 1/3πr^2(d/dt)[d]
dV/dt = 1/3πr^2(d/dt)[2]
dV/dt = 2/3πr^2
The rate of change of the volume of water with respect to time is given as -13 cubic feet per minute. Therefore, substituting this into the expression above, we get:
-13 = 2/3π(6 ft)2(d/dt)
When we simplify the above equation, we get:
d/dt = -13/72π
Therefore, when the water is 2 feet high, the depth of the water changes at a rate of -13/72π feet per minute.

Anastasia has a part-time job and earns the same amount of money each week. She decided to deposit all her
weekly earnings in a savings account, which originally had $225. After making deposits for 11 weeks, she
had $665 in her account. How much money will be in her account after 24 weeks? Show how you arrived at
your answer.
We can start by finding how much money Anastasia saves each week.
The difference between her starting balance and ending balance after 11 weeks is:
$665 - $225 = $440
So, over 11 weeks, Anastasia has saved a total of $440.
To find how much money she saves each week, we can divide the total savings by the number of weeks:
$440 ÷ 11 weeks = $40 per week
This means that Anastasia saves $40 each week.
To find out how much money she will have in her account after 24 weeks, we can multiply the amount she saves each week by the number of weeks:
$40 per week × 24 weeks = $960
Therefore, after 24 weeks, Anastasia will have $960 in her savings account.

Mackenzie just started training for a marathon. According to her plan, she must run 19 miles the first week and 25 miles the second week. What is the percent increase?
the percent increase from running 19 miles in the first week to 25 miles in the second week is 31.58%. This means that Mackenzie increased her mileage by 31.58% from the first week to the second week.
To calculate the percent increase from running 19 miles in the first week to 25 miles in the second week, we first need to find the difference between the two numbers.
The difference is calculated as follows:
25 - 19 = 6
So, the difference between the two weeks is 6 miles.
To find the percent increase, we need to divide the difference by the original value and then multiply by 100.
The formula for percent increase is:
(percent increase) = [(new value - old value) / old value] x 100%
Using this formula, we can find the percent increase in Mackenzie's training as follows:
(percent increase) = [(25 - 19) / 19] x 100%
(percent increase) = (6 / 19) x 100%
(percent increase) = 0.3158 x 100%
(percent increase) = 31.58%
So, the percent increase from running 19 miles in the first week to 25 miles in the second week is 31.58%. This means that Mackenzie increased her mileage by 31.58% from the first week to the second week.
It's important to note that a large percent increase in mileage can increase the risk of injury, so it's important to gradually increase mileage over time to prevent injury and ensure a successful training program.

Assume that women's weights are normally distributed with a mean given by μ=143
lb and a standard deviation given by σ=29
lb.
(b) If 4 women are randomly selected, find the probability that they have a mean weight below 108
(c) If 58 women are randomly selected, find the probability that they have a mean weight below 108
The probability that 4 women have a mean weight below 108 lb is approximately 0.008.
The probability that 58 women have a mean weight below 108 lb is zero.
What is the probability?The probability is determined using the central limit theorem.
(b) If 4 women are randomly selected, the sample mean weight (x) will also be normally distributed:
mean = 143 lb
standard deviation = 29/√(4)
standard deviation = 14.5 lb.
We can use the z-score formula to find the probability that the sample mean weight is below 108 lb:
z = (108 - 143) / 14.5
z = -2.41
Using a standard normal distribution table or calculator, the probability of z being less than -2.41 is approximately 0.008.
(c) If 58 women are randomly selected, the sample mean weight (x) will also be normally distributed:
mean = 143 lb
standard deviation = 29/√(58)
standard deviation = 3.81 lb
We can use the z-score formula to find the probability that the sample mean weight is below 108 lb:
z = (108 - 143) / 3.81 ≈ -9.21
Using a standard normal distribution table or calculator, the probability of z being less than -9.21 is extremely small, practically zero.

Graph the boundary lines of the linear inequalities on the graph below.
Also, plot the points that are part of the solution set from the list below.
(3, 7), (2, 2), (8, 1), (10, 2), (5, 5)
The points that are part of the solution set are (3, 7), (8, 1), and (10, 2).
What do you mean by Coordinate plane ?The coordinate plane is a two-dimensional space formed by two perpendicular lines called the x-axis and y-axis. The point where the two axes intersect is called the origin. Each point in the plane is identified by a pair of numbers called its coordinates, where the first number represents its position along the x-axis and the second number represents its position along the y-axis. Coordinates are typically written as (x, y), with the x-coordinate listed first and the y-coordinate listed second. The coordinate plane is commonly used in mathematics to graph and analyze equations, functions, and geometric shapes.
Let x be the number of bags of popcorn and y be the number of bags of cotton candy. Then the cost constraint is:
3x + 7y ≤ 56
We also have the constraint that Chris needs at least 7 bags of popcorn:
x ≥ 7
To graph these constraints, we can rewrite them in slope-intercept form:
y ≤ (-3/7)x + 8
x ≥ 7
The first inequality has a slope of -3/7 and a y-intercept of 8, and the second inequality is a vertical line at x = 7.
To plot the points that are part of the solution set, we can simply plug them into the two inequalities and see if they are true. The points that satisfy both inequalities are part of the solution set.
(3, 7) satisfies both inequalities:
7 ≤ (-3/7)(3) + 8
3 ≥ 7
(2, 2) does not satisfy the first inequality:
2(7) > 3(2) + 7
(8, 1) satisfies both inequalities:
1 ≤ (-3/7)(8) + 8
8 ≥ 7
(10, 2) satisfies both inequalities:
2 ≤ (-3/7)(10) + 8
10 ≥ 7
(5, 5) does not satisfy the first inequality:
5(7) > 3(5) + 7
Therefore, the points that are part of the solution set are (3, 7), (8, 1), and (10, 2).
To graph these on the coordinate plane, we can plot the vertical line x=7 and the line y= (-3/7)x + 8, and then shade in the feasible region below the line and to the right of the vertical line.

Therefore , the solution of the given problem of angles comes out to be lim x→2 g(x) = lim x→2 [(x² - 4)/(x - 2)] = 4.
What does an angle mean?Both the largest and the tiniest walls of a skew are determined by an intersection of the lines that connect that make up its ends. A junction could possibly bring two routes together. Another result of two objects interacting is an angle. They most closely resemble dihedral shapes. Two line beams can be arranged in a variety of ways between their extremities to form a two-dimensional curve.
Here,
The abbreviated formula for f(x) = (4x³ - 3x² - 10x - 3)/(x³ - x² - 6x) is as follows:
f(x) = (4x³ - 3x² - 10x - 3)/(x³ - x² - 6x)
f(x) = [(4x³ - 12x) + (9x² - 3)] / (x(x² - x - 6))
f(x) = [4x(x² - 3) + 3(3x² - 1)] / [x(x - 3)(x + 2)]
f(x) = [4x/(x-3)] + [3/(x+2)] - [3x/(x²-x-6)]
Consequently, the abbreviated form is:
f(x) = [4x/(x-3)] + [3/(x+2)] - [3x/(x²-x-6)]
Direct substitution can be used to find the limit of the equation g(x) = (x2 - 4)/(x - 2) as x approaches 2, which results in the undetermined form 0/0. In order to take the derivative of the numerator and denominator with regard to x, we can apply L'Hopital's rule as follows:
g(x) = (x² - 4)/(x - 2)
g'(x) = [(2x) * (x - 2) - (x² - 4) * 1] / (x - 2)²
g'(2) = 4
As x gets closer to 2, the maximum of g(x) is as follows:

m∠1= 2x° and =m∠2=(x+69°.
The measures of the angles are m∠1 = 74° and m∠2 = 74°.
Given,
[tex]m\angle1 = 2x^\circ[/tex]
[tex]m\angle2 = (x + 69)^\circ[/tex]
We need to find the measure of these angles.
What is a straight line angle?The straight line angle is 180 degrees.
If the angle is split the sum must be equal to 180 degrees.
We have,
[tex]m\angle1 = 2x^\circ[/tex]
[tex]m\angle2 = (x + 69)^\circ[/tex]
The figure is at a straight-line angle.
So we have,
[tex]m\angle1 + m\angle2 = 180^\circ[/tex]
[tex]2x^\circ + (x + 69)^\circ = 180[/tex]
[tex]2x + x + 69 = 180[/tex]
[tex]3x + 69 = 180[/tex]
[tex]3x = 180 - 69[/tex]
[tex]3x = 111[/tex]
[tex]x = 111\div3[/tex]
[tex]x = 37[/tex]

the sum of the lengths of the three sides of a right triangle is equal to 18 and the sum of the squares of the lengths of the three sides is equal to 128. what is the area of the triangle?
The area of this triangle was 18 square units.
Let's use the given information to set up some equations. We are told that the sum of the lengths of the three sides of the triangle is 18. Let's call the lengths of the two shorter sides a and b, and the length of the hypotenuse c. Then, we have a + b + c = 18.
We are also told that the sum of the squares of the lengths of the three sides is 128. Using the Pythagorean theorem, we know that a² + b² = c². So, we can rewrite this equation as a² + b² + c² = 128.
Now we have two equations with three variables. We need to find a way to eliminate one of the variables. We can do this by using the first equation to solve for one of the variables in terms of the other two. Let's solve for c:
c = 18 - a - b
Now we can substitute this expression for c into the second equation:
a² + b² + (18 - a - b)² = 128
Expanding and simplifying, we get:
2a² + 2b² - 36a - 36b + 144 = 0
Dividing by 2, we get:
a² + b² - 18a - 18b + 72 = 0
We can rewrite this equation as:
(a² - 18a + 81) + (b² - 18b + 81) = 38
Completing the square, we get:
(a - 9)² + (b - 9)² = 5
So we have:
(a - 9)² = 1
(b - 9)² = 1
This gives us four possible solutions:
a = 8, b = 10, c = 18 - a - b = 0 (not possible)
a = 10, b = 8, c = 18 - a - b = 0 (not possible)
a = 9, b = 9, c = 0 (not possible)
a = b = c = 6√2
The only valid solution is the last one, where all three sides have the same length of 6√2. To find the area of the triangle, we can use the formula:
Area = (base x height)/2
Since this is a right triangle, one of the sides is the base and the other is the height. So we can choose any two sides to use as the base and height. Let's choose a and b:
Area = (a x b)/2
Substituting the values a = 6√2 and b = 6√2, we get:
Area = (6√2 x 6√2)/2
Area = 36/2
Area = 18
Therefore, the area of the right triangle with sides of length 6√2 is 18 square units.

Leslie’s brother weighs 16.7 kg. Leslie weighs 12.4 kg. Leslie’s dad
weighs 67.6 kg. How much heavier is Leslie’s dad than the two
children together?
Leslie's dad is 38.5 kg heavier than the combined weight of Leslie and her brother.
To solve the problem, we first need to find the total weight of the two children together, and then subtract that from the weight of Leslie's dad:
Total weight of the two children = Leslie's weight + her brother's weight
Total weight of the two children = 12.4 kg + 16.7 kg
Total weight of the two children = 29.1 kg
Weight difference between Leslie's dad and the two children = Leslie's dad's weight - Total weight of the two children
Weight difference between Leslie's dad and the two children = 67.6 kg - 29.1 kg
Weight difference between Leslie's dad and the two children = 38.5 kg
Therefore, Leslie's dad is 38.5 kg heavier than the two children combined.

Therefore, P(A|BC) = 4/7.
a. P(A|B)
We can use Bayes' theorem to calculate P(A|B):
P(A|B) = P(A ∩ B) / P(B)
We are given that P(A ∩ B) = 0.2 and P(B) = 0.3, so:
P(A|B) = 0.2 / 0.3 = 2/3
Therefore, P(A|B) = 2/3.
b. P(AC ∩ BC)
Using the complement rule, we can rewrite AC ∩ BC as (A ∪ B)C:
AC ∩ BC = (A ∪ B)C
Using De Morgan's laws, we can further rewrite this as:
AC ∩ BC = A'C ∩ B'C
Now, we can use the distributive property to write:
A'C ∩ B'C = (A ∪ B)'
Using the complement rule again, we have:
A'C ∩ B'C = 1 - P(A ∪ B)
We can use the inclusion-exclusion principle to calculate P(A ∪ B):
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
We are given that P(A) = 0.6, P(B) = 0.3, and P(A ∩ B) = 0.2, so:
P(A ∪ B) = 0.6 + 0.3 - 0.2 = 0.7
Therefore:
A'C ∩ B'C = 1 - 0.7 = 0.3
Hence, P(AC ∩ BC) = 0.3.
c. P(A ∩ BC)
Using the complement rule, we can write BC as 1 - B:
A ∩ BC = A ∩ (1 - B)
We can distribute the intersection over the complement:
A ∩ BC = A - (A ∩ B)
We are given that P(A) = 0.6 and P(A ∩ B) = 0.2, so:
A ∩ BC = 0.6 - 0.2 = 0.4
Therefore, P(A ∩ BC) = 0.4.
d. P(A|BC)
We can use Bayes' theorem again to calculate P(A|BC):
P(A|BC) = P(A ∩ BC) / P(BC)
Using the complement rule, we can write BC as 1 - B:
P(A|BC) = P(A ∩ (1 - B)) / P(1 - B)
We can distribute the intersection over the complement:
P(A|BC) = P(A) - P(A ∩ B) / P(1 - B)
We are given that P(A) = 0.6, P(A ∩ B) = 0.2, and P(B) = 0.3, so:
P(A|BC) = 0.6 - 0.2 / (1 - 0.3) = 0.4 / 0.7
Therefore, P(A|BC) = 4/7.

The measure of angle WZQ is 92°.
What is the measure of angle QZX?
Enter your answer in the box.
a
°
Angle W Z Q. Ray Z X is drawn between ray Z W and Z Q. Angle W Z X is labeled 63 degrees. Angle Q Z X labeled with a question mark.
To find the measure of angle QZX, we need to use the fact that the sum of the angles in a triangle is 180 degrees.
First, we can find the measure of angle ZWQ:
Angle WZQ + Angle WZX = 180 degrees
92 degrees + 63 degrees = 155 degrees
Therefore, angle ZWQ has a measure of 155 degrees.
Now, we can find the measure of angle QZX:
Angle ZWQ + Angle QZX = 180 degrees
155 degrees + Angle QZX = 180 degrees
Subtracting 155 from both sides, we get:
Angle QZX = 25 degrees
Therefore, the measure of angle QZX is 25 degrees.
