Answer:

\( \sqrt{30} \)

There are 30 of 1/10's in the number 3

From the question, we have the following parameters that can be used in our computation:

How many 1/10's are in 3?​

The above statement is a quotient expression that has the following features

Dividend = 3

Divisor = 1/10

So, we have

Quotient = Dividend /Divisor

Substitute the known values in the above equation, so, we have the following representation

Quotient = 3/(1/10)

Evaluate

Quotient = 30

Hence, there are 30 1/10's

To find the value of LS(R), we can use the concept of the Late Finish (LF) and Late Start (LS) times in project scheduling.

The Late Start time for an activity is the latest possible time it can start without delaying the project, while the Late Finish time is the latest possible time it can finish without delaying the project.

Given the LF values for activities K, P, and C, we can work backward to calculate the LS values and eventually determine the value of LS(R). Here's how:

1. Start with the activity C:

  - LF(C) = 121

  - Duration of C = 53 days

  - LS(C) = LF(C) - Duration of C = 121 - 53 = 68

2. Move to the activities that are dependent on C, which is only activity R:

  - IP(R) = C

  - LS(R) = LF(C) - Duration of R = 121 - 28 = 93

Therefore, the value of LS(R) is 93.

The slope is the steepness of a line on a graph and represents the ratio of the vertical change to the horizontal change, the rate of change refers to the amount of change in one variable corresponding to a unit change in another variable.

The slope of a line is a measure of its steepness or incline. It is calculated by dividing the vertical change (change in y-values) by the horizontal change (change in x-values) between two points on the line. The slope indicates how much the dependent variable (y) changes with respect to a unit change in the independent variable (x). In other words, it represents the ratio of the rise (vertical change) to the run (horizontal change) on the graph.

On the other hand, the rate of change is a broader concept that applies to any relationship between two variables, not just linear relationships. It measures how one variable changes in response to a unit change in another variable. The rate of change can be positive, indicating an increase in one variable for every unit increase in the other variable, or negative, indicating a decrease. It can also vary across different intervals of the relationship, indicating that the relationship is not constant.

In summary, the slope specifically refers to the steepness of a line on a graph and is calculated as the ratio of the vertical change to the horizontal change. The rate of change, on the other hand, is a more general concept that describes how one variable changes in response to a unit change in another variable and can be applied to any type of relationship between variables.

Area of a triangle = 1/2 (base x height) Here, we are given the height of the triangle as 10 m; hence, we can use the above formula to determine the base of the triangle.

Area of a triangle = 1/2 (b x 10) Given that we want the base of the triangle, we can rearrange the above equation to obtain the following:

b = (2 x Area of a triangle)/10

Since we do not have the value of the area of the triangle, we will use the Pythagorean theorem to find the third side, which will assist us in determining the area of the triangle.

Pythagorean Theorem states that:

Hence, we can use this theorem to calculate the third side of the triangle. The triangle's hypotenuse is equal to 10m, which is the given height of the triangle.

The root of the graph of function f(x) = (x-5)³(x+2)² touch the x-axis at -2 and 5.

Given that,

The function is f(x)= (x-5)³(x+2)²

We have to find at which root does the graph function touch the x-axis.

We know that,

Mathematical calculus' core component is functions. The unique forms of relationships are the functions. When it comes to arithmetic, a function is represented as a rule that produces a different result for each input x.

Take the function

f(x) = (x-5)³(x+2)²

f(x) = 0 if a curve touches the x-axis.

⇒ (x - 5)³(x + 2)² = 0.

But if ab = 0

So, a=0 and b=0

⇒ (x - 5)³ = 0 and (x + 2)² = 0

⇒ (x - 5) = 0 and x + 2 = 0

⇒ x=5 and x=-2.

According to the uniform distribution, there is a 0.1= 10% chance that a worker selected at random will have an annual wage between $45,000 and $60,000.

Uniform Distribution:

In statistics, uniform distribution refers to a type of probability distribution in which all outcomes are equally likely. A deck of cards has within it uniform distributions because the likelihood of drawing a heart, a club, a diamond, or a spade is equally likely.

An uniform distribution has two bounds, a and b.  

The probability of finding a value between c and d is:

P(c ≤ X ≤ d) = \(\frac{d-c}{b-a}\)

given that , workers' salaries in your company are uniformly distributed between $10,000 and $60,000 per year

a = 10,000 , b= 60,000 , c = 45,000 and d = 50,000

The probability is

P(45,000 ≤ X ≤ 50,000) = \(\frac{50,000-45,000}{60,000-10,000}\)

                                       = 0.1

Answer:

Move decimal points in 726.02, 3 points in the left direction

Step-by-step explanation:

Given

Quotient of 726.02 and 1000

This is represented as:

\(Quotient = \frac{726.02}{1000}\)

The denominator 1000 has 3 zeros.

This implies that the decimal points will be moved in the left direction by 3 points.

So:

\(Quotient = \frac{726.02}{1000}\)

\(Quotient = 0.72602\)

Answer:

To find the quotient of 726.02 and 1,000, move the decimal point in 726.02 three places to the left.

\(x~=~\Large\boxed{7}\)

\(RS~=~\Large\boxed{6}\)

\(RT~=~\Large\boxed{17}\)

Step-by-step explanation:

Given information

\(RS=2x-8\)

\(ST=11\)

\(RT=x+10\)

Derived expression from the given information

Presumably, I think this is a combination of segments

\(RS+ST=RT\)

Substitute values into the given expression

\((2x-8)+(11)=(x+10)\)

Combine like terms

The following is the expression

\(\Large\boxed{2x+3=x+10}\)

Subtract 3 on both sides

\(2x+3-3=x+10-3\)

\(2x=x+7\)

Subtract x on both sides

\(2x-x=x+7-x\)

\(\Large\boxed{x=7}\)

Substitute the x value into corresponding expressions to determine the final value

\(RS=2x-8=2(7)-8=14-8=\Large\boxed{6}\)

\(RT=x+10=(7)+10=\Large\boxed{17}\)

To find the parametric equations for the tangent line to the curve at the point (2,4,1), we need to first find the derivative of the parametric equations with respect to t.

Taking the derivative of x = t^2 + 1 with respect to t, we get dx/dt = 2t.

Taking the derivative of y = 4√t with respect to t, we get dy/dt = 2/√t.

Taking the derivative of z = et^2-t with respect to t, we get dz/dt = (2t-1)et^2-t.

At the point (2,4,1), t = 2. Therefore, dx/dt = 4, dy/dt = 1, and dz/dt = 6e^2.

So, the direction vector of the tangent line is (4,1,6e^2).

To find the parametric equations, we use the point-slope form of a line.

Let r(t) = (x,y,z) be the point on the tangent line. Then,

r(t) - (2,4,1) = t(4,1,6e^2).

Expanding, we get

x - 2 = 4t,

y - 4 = t,

z - 1 = 6e^2t.

Therefore, the parametric equations for the tangent line are

x = 4t + 2,

y = t + 4,

z = 6e^2t + 1.

b. No, there is no BST B and a query value X such that the search for X in B visits the following sequence of key values in the given order.

c. Yes, there is a BST t and a query value x such that the search for x in t visits the following sequence of key values in the given order.

A binary search tree (BST) is a data structure used to store a set of elements in a way that allows efficient search, insertion, and deletion operations.

It is a binary tree in which each node has at most two children, called left and right children.

Here the values are 11, 41, 71, 101, 141 The given questions can be answered as follows

(a) Yes, it is possible to construct a BST where the search for x visits the sequence of key values 11, 41, 71, 101, 141.

(b) No, it is not possible to construct a BST where the search for x visits the sequence of key values 101, 141, 41, 11.

This is because in BST, the values to the left of a node are always smaller than the node's values, and the values to the right are always larger.

Therefore, if the search reaches a node with a value greater than the value of the query, it will never be reached

revisit nodes with smaller values.

(c) Yes, it is possible to construct a BST where the search for x visits the key value 1 sequence. The tree would consist of a single node with a key value of 1.

Therefore

a. Yes, there is a BST B and a query value X, so a search for X from B visits the next sequence of key values in the given order.

b. No, there is no BST B and a query value of X, so a lookup of X from B visits the next sequence of key values in the given order. c. Yes, there is a BST t and a query value x, so a search for x from t visits the next sequence of key values in the given order.
