Answer:
To find the volume of a cone with radius 9 feet and height 4 feet, we can use the formula:

V = (1/3) * π * r^2 * h

Plugging in the values:

V = (1/3) * π * (9^2) * 4

Calculating:

V = (1/3) * π * 81 * 4

V ≈ 108.19 cubic feet

Therefore, the volume of the cone is approximately 108.19 cubic feet (rounded to two decimal places)

To solve the equations:

O + O + O = 30

1 - 3 - 5 - 7

9 - 11 -

15

We can start by simplifying the second equation:

1 - 3 - 5 - 7 = -14

9 - 11 - x = -14

To find the value of x, we can solve the equation:

-11 - x = -14

Adding 11 to both sides of the equation:

-11 + 11 - x = -14 + 11

Simplifying:

-x = -3

Multiplying both sides by -1:

(-1) * (-x) = (-1) * (-3)

x = 3

Now, substituting the value of x back into the second equation:

9 - 11 - 3 = -14

-5 - 3 = -14

-8 = -14

This is not a true statement. Therefore, the values provided do not satisfy the equations given.

"dom(R) ⊂ UU R" means that the domain of relation R is a subset of the universal set associated with relation R

The notation "dom(R) ⊂ UU R" refers to the domain of a relation R being a subset of the universal set U.

Let me help you to break it down

1. dom(R): This represents the domain of the relation R. The domain of a relation is the set of all elements that appear as the first component in any ordered pair of the relation.

2. ⊂: This symbol indicates a subset relationship, meaning that the set on the left-hand side is a subset of the set on the right-hand side. In this case, "dom(R) ⊂ U" implies that the domain of relation R is a subset of the universal set U.

3. "UU R": The term "UU R" likely represents the universal set associated with relation R. It indicates the set that contains all possible elements that can be related by R.

The velocity represented by vector AC of Michelle's canoe is approximately option C. 11.2 miles per hour.

To determine the velocity, represented by vector AC, of Michelle's canoe, use the concept of vector addition.

Break down the motion into its components:

1. Paddling due east at 10 miles per hour: This motion can be represented by a vector pointing in the positive x-direction with a magnitude of 10 mph.

2. Wind blowing due south at 5 miles per hour: This motion can be represented by a vector pointing in the negative y-direction with a magnitude of 5 mph.

To find the resultant velocity, add these two vectors. Using the Pythagorean theorem, calculate the magnitude of the resultant velocity:

AC² = AB² + BC²

AB (paddling east) = 10 mph

BC (wind blowing south) = -5 mph (negative sign due to opposite direction)

AC² = (10 mph)² + (-5 mph)²

AC² = 100 mph² + 25 mph²

AC² = 125 mph²

Taking the square root of both sides:

AC ≈ √(125) mph

AC ≈ 11.2 mph (rounded to the nearest tenth)

Therefore, the velocity represented by vector AC of Michelle's canoe is approximately 11.2 miles per hour.

The correct answer is option C: 11.2 miles per hour.

It will take the truck 9 hours to travel from warehouse A to warehouse B.

To determine the time it takes for the truck to travel from warehouse A at (-4, 8) to warehouse B at (-4, -1), we need to calculate the distance between these two points and then convert it to time using the given unit of 20 miles per hour.

First, let's find the vertical distance between the two points. The y-coordinate of warehouse A is 8, and the y-coordinate of warehouse B is -1. So the vertical distance is 8 - (-1) = 9 units.

Next, we convert the vertical distance to miles. Since each unit represents 20 miles per hour, we multiply the vertical distance by 20: 9 units × 20 miles/unit = 180 miles.

Now, we can calculate the time it takes to travel this distance. We divide the distance by the speed of the truck, which is 20 miles per hour: 180 miles / 20 miles per hour = 9 hours.

Therefore, it will take the truck 9 hours to travel from warehouse A to warehouse B.

Answer: its D! not 8!!!

Step-by-step explanation:

Therefore, we would predict that a catfish with a length of 33 inches would weigh approximately 26.5 pounds.

Jin has decided to research the relationship between the length in inches and the weight of a certain species of catfish. He measures the length and weight of a number of specimens he catches, then throws back into the water. After plotting all his data, he draws a line of best fit.

The given problem is related to a scatter plot, which depicts the relationship between the length in inches and the weight of a certain species of catfish. Based on the scatter plot, it is clear that there is a positive correlation between length and weight.

The correlation between the two variables can be measured using the correlation coefficient, r, which ranges between -1 and 1, where -1 denotes a perfect negative correlation, 1 denotes a perfect positive correlation, and 0 denotes no correlation.

The line of best fit can be determined using the method of least squares.

This method minimizes the sum of the squared errors between the observed values and the predicted values.

The equation of the line of best fit is

y = mx + b,

where m is the slope of the line and b is the y-intercept.

To predict the weight of a catfish with a length of 33 inches, we need to use the equation of the line of best fit.

Let's assume that the equation of the line of best fit is

y = 0.5x + 10,

where y is the weight of the catfish in pounds and x is the length of the catfish in inches.

Then, we can substitute x = 33 into the equation to obtain:

y = 0.5(33) + 10

   = 16.5 + 10

   = 26.5

The sequence of transformations that maps triangle ABC onto triangle A'B'C' is a translation by (+8, -6) followed by a reflection across the y-axis.

To determine the sequence of transformations that maps triangle ABC onto triangle A'B'C', let's analyze the given coordinate points.

Triangle ABC:

A (-4, 4)

B (-8, 2)

C (-6, -6)

Triangle A'B'C':

A' (4, -2)

B' (2, 2)

C' (6, 0)

By comparing the corresponding vertices, we can identify the transformations:

Translation:

To transform A to A', we can observe that A' is obtained by moving 8 units to the right and 6 units downwards from A. Therefore, the first transformation is a translation by (+8, -6).

Reflection:

Next, we notice that B' is the reflection of B across the y-axis. Thus, the second transformation is a reflection about the y-axis.

Therefore, the sequence of transformations that maps triangle ABC onto triangle A'B'C' is a translation by (+8, -6) followed by a reflection across the y-axis.

Maths. Algebra. We must eliminate any factors that are shared by each word in an expression before we can factorize it. Expanding brackets is the process's reverse.

Finding an expression's highest common factor (HCF), or the largest number or letter that each term can be split by, is necessary to ensure that it has been properly factorized.
