Main Answer: If ab = 4, then (a – b)3 – 9(a – b) = 0.

Supporting Explanation :Given that ab = 4To prove that (a – b)3 – 9(a – b) = 0.(a – b)3 – 9(a – b) = 0 can be written as (a-b)[(a-b)²-9]=0(a-b)²-9=0(a-b)²=9a-b=3 or a-b=-3as ab=4Let's take a=4 and b=1So, a-b=3(a-b)³-9(a-b)=0So, (3)³-9(3)=0 Therefore, (a – b)³ – 9(a – b) = 0 when a=4 and b=1.

The collection of whole numbers and negative numbers is known as an integer in mathematics. Integers, like whole numbers, do not include the fractional portion. Integers can therefore be defined as numbers that can be positive, negative, or zero but not as fractions. On integers, we can carry out all arithmetic operations, including addition, subtraction, multiplication, and division. Integer examples include 1, 2, 5, 8, -9, -12, etc. "Z" stands for an integer.

The number of tomato plants over the height of 18 inches, when treated with grow well is, GW = 3 + 2 = 5

Therefore, GG > GW

Hence, the statement is true.

(B) As statement A is true, this statement is false.

(C) The tomato plants over 18 inches when administered with green grow, GG = 6 + 12 = 18

The tomato plants over 18 inches when administered with grow well, GW = 3 + 2 = 5.

As GG ≠ GW, the statement is false.

(D) As the number of tomato plants over 18 inches when treated with green grow is greater than when treated with grow well. Hence, the statement is false.

Yes, the forester was justified in using a Normal model to analyze the woods, because the histogram is unimodal and symmetric. So option A is correct.

A histogram is a type of graph that uses vertical bars to show the distribution of a set of data. This particular histogram is unimodal, meaning that it has one peak which is an indication that the data is distributed normally. Additionally, the histogram is symmetric, which is another indication that the data is normally distributed.
Using a Normal model to analyze the woods is a valid approach because it allows the forester to identify the average diameter of the trees, as well as the spread of the data. It also allows him to check for any outliers, or points that fall outside the normal range. With this information, the forester can determine if the woods is suitable for sale, or if the buyer should be aware of any unexpected features.
Overall, the histogram is an effective way for the forester to analyze the data and determine if a Normal model is appropriate. By noting the unimodal and symmetric nature of the histogram, the forester can be sure that a Normal model will accurately represent the data, allowing him to make an informed decision about the woods.

Answer:

y = 5

Step-by-step explanation:

Solving for y:

\(-42-11y=-97\\-11y=-55\\y=5\)

Answer:

  C.  142°

Step-by-step explanation:

You want the angle between vectors u=3i+√3j and v=-2i-5j.

There are a number of ways the angle between the vectors can be found. For example, the dot-product relation can give you the cosine of the angle:

  u•v = |u|·|v|·cos(θ) . . . . . . where θ is the angle of interest

You can find the angles of the vectors individually, and subtract those:

  u = |u|∠α

  v = |v|∠β

  θ = α - β

When the vectors are expressed as complex numbers, the angle between them is the angle of their quotient:

  \(\dfrac{\vec{u}}{\vec{v}}=\dfrac{|\vec{u}|\angle\alpha}{|\vec{v}|\angle\beta}=\dfrac{|\vec{u}|}{|\vec{v}|}\angle(\alpha-\beta)=\dfrac{|\vec{u}|}{|\vec{v}|}\angle\theta\)

This method is used in the calculation shown in the first attachment. The angle between u and v is about 142°.

A graphing program can draw the vectors and measure the angle between them. This is shown in the second attachment.

__

Additional comment

The approach using the quotient of the vectors written as complex numbers is simply computed using a calculator with appropriate complex number functions. There doesn't seem to be any 3D equivalent.

The dot-product relation will work with 3D vectors as well as 2D vectors.

The solution to the question \(-7 \frac{2}{3} + (-5\frac{1}{2} ) + 8\frac{3}{4}\) is \(-4\frac{5}{12}\).

To solve this problem, we need to add up all the given numbers. To make the addition process easier, we can convert all the mixed numbers into improper fractions first.

\(-7\frac{2}{3}\) =\(-(\frac{21+2}{3} )\)= \(-\frac{23}{3}\)

\(-5\frac{1}{2}\) = \(-(\frac{10+1}{2} )\)= \(-\frac{11}{2}\)

\(8\frac{3}{4}\) = \(\frac{32+3}{4}\) = \(\frac{35}{4}\)

Now we can add up the three fractions:

\(-\frac{23}{3}+ -\frac{11}{2}+\frac{35}{4}\)

We must choose a common denominator so that we can sum up these fractions. The smallest common multiple of 3, 2, and 4 is 12.

Therefore,

\(\frac{(-23*4)+(-11*6)+(35*3)}{12}\)

\(\frac{-92-66+105}{12} \\\frac{-53}{12}\)

Therefore, the solution is \(\frac{-53}{12}\). We can also convert this back into a mixed number if required:

\(\frac{-53}{12}\) = \(-\frac{(4*8+5)}{12}\) =\(-4\frac{5}{12}\).

So the final answer is \(-4\frac{5}{12}\).

Livingston is approximately 8.2 miles away from Chandler's house, measured in a straight line.

To find the distance between Livingston and Chandler's house, we can use the Pythagorean theorem because we have a right triangle formed by Springtown, Chandler's house, and Livingston.

Let's assign variables to the distances:

Let x be the distance from Livingston to Chandler's house (in miles).

Let y be the distance from Springtown to Chandler's house (in miles).

Given information:

Springtown is 6 miles away from Chandler's house (y = 6).

Livingston is 10 miles away from Springtown.

Using the Pythagorean theorem:

According to the theorem, the square of the hypotenuse (the distance between Livingston and Chandler's house) is equal to the sum of the squares of the other two sides.

Applying the theorem, we have:

x² = y² + (10)²

x² = 6² + 10²

x² = 36 + 100

x² = 136

Taking the square root of both sides:

x = √136

x ≈ 11.66

Therefore, Livingston is approximately 8.2 miles away from Chandler's house, measured in a straight line.
