Answer:

8√2

Step-by-step explanation:

Notice that this is a 45-45-90 triangle (isosceles right triangle). This type of triangle has a  property where the ratio between side lengths is x : x : x√2, where x√2 is the measure of the two equal legs and is the measure of the hypotenuse.

Since we know the measure of one of the smaller legs is 8, then we can set x in the ratio to 8 -->  8 : 8 : 8√2

Thus, the length of BC (hypotenuse) is 8√2

Step-by-step explanation:

For function f(x), the average rate of change from x = a to x = b is:

average rate of change = (f(b) - f(a))/(b - a)

Here we have:

f(a) = f(-3) = -2.88

f(b) = f(2.5) = 2.62

average rate of change = (2.62 - (-2.88))/(2.5 - (-3)) = 1

The set of natural numbers {1,2,3,4,...} and the set of positive even numbers {2, 4, 6, 8, . . .} are different because natural numbers include all positive integers, while even numbers only include those that are divisible by 2 with no remainder.

Two important sets of numbers are natural numbers and even numbers. The set of natural numbers consists of numbers that are not negative, beginning with 1 and continuing indefinitely with 2, 3, 4, and so on.

The set of even numbers, on the other hand, consists of numbers that are divisible by 2, beginning with 2, 4, 6, and so on.

Positive integers refer to natural numbers. Any integer greater than zero is a positive integer.

Zero is not a positive integer. Hence, the set of natural numbers consists of {1,2,3,4,…}

On the other hand, the set of even numbers consists of {2, 4, 6, 8, . . .}.

Therefore, {1,2,3,4,…} and {2, 4, 6, 8, . . .} are two different sets of numbers where one set is composed of positive integers (natural numbers) and the other is composed of positive even numbers.

The correct statements regarding activity diagrams are:

a. There can be multiple end points, but only one starting point.

c. A branch can have multiple incoming arrows.

d. A decision point may have more than 2 outgoing arrows.

e. An indeterminacy is created when the successors of an activity have non-mutually exclusive conditions.

f. An activity can be nested within another activity.

Activity diagrams are graphical representations used in software engineering to depict the flow of activities or actions within a system. The correct statements regarding activity diagrams are as follows:

a. There can be multiple end points, but only one starting point:

Activity diagrams typically illustrate the flow of activities from a single starting point to multiple end points. This allows for depicting different termination points in the system's behavior.

c. A branch can have multiple incoming arrows:

A branch in an activity diagram represents a decision point where the flow of activities can diverge. It is possible for multiple incoming arrows to converge at a branch, indicating different paths leading to the decision point.

d. A decision point may have more than 2 outgoing arrows:

A decision point in an activity diagram represents a condition or a decision that determines the subsequent flow of activities. It is possible for a decision point to have more than two outgoing arrows, indicating different paths based on the decision outcome.

e. An indeterminacy is created when the successors of an activity have non-mutually exclusive conditions:

In an activity diagram, if the subsequent activities following a certain action have conditions that are not mutually exclusive, it creates an indeterminacy. This means that multiple paths may be followed simultaneously based on the different conditions.

f. An activity can be nested within another activity:

Activity diagrams support the nesting of activities within each other. This allows for representing complex activities or sub-processes within a larger activity, providing a hierarchical structure to the diagram.

In conclusion, the correct statements regarding activity diagrams include multiple end points and a single starting point, the possibility of multiple incoming arrows at a branch, the presence of more than two outgoing arrows at a decision point, the creation of indeterminacy with non-mutually exclusive conditions, and the ability to nest activities within one another.

• y_O = observed time spent exercising (in hours),

• y_P = predicted time spent exercising (in hours).

• r = residual (in hours) = y_O - y_P.

From the statement, we have the following equation for the line of best fit:

1) For x = 4.0 we have:

• y_O = 4.50 (from the table),

• y_P = 5.36 (by using the formula),

• r = 4.50 - 5.36 = 0.86.

The correct answer is

b) Below 0

The correct option is (d) To the left of 0.

If the graph for a linear regression crosses the y-axis in negative values, the y-intercept of the regression line would be located to the left of 0 on the y-axis.

Therefore, the correct option is (d) To the left of 0. How to find the y-intercept of the regression line?

The y-intercept of a regression line is the value where the regression line intersects with the y-axis. It is the point where x = 0. In order to find the y-intercept of the regression line, we can use the equation of the regression line, which is y = mx + b. Here, m is the slope of the line and b is the y-intercept.

Therefore, if the regression line crosses the y-axis in negative values, it means that the y-intercept (b) is negative, and the line intersects the y-axis to the left of 0.

The number in the arithmetic sequence close to 100 is 102

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the arithmetic sequence be represented as A

Now , the equation will be

A = 14 , 22 , 30 , 38 ...

Now , the common difference of the AP is d = 8

The 12th term of the AP is

a₁₂ = 14 + ( 12 - 1 ) d

a₁₂ = 14 + 11 ( 8 )

a₁₂ = 14 + 88

a₁₂ = 102

Hence , the 12th term of the AP is 102

The value of the integral is (11/15)√3.

First, we can simplify the integrand using the trigonometric substitution:

Let x = 2sinθ

Then dx = 2cosθ dθ and 4x^2 - x^4 = 4(2sinθ)^2 - (2sinθ)^4 = 4(4sin^2θ - sin^4θ) = 4sin^2θ(4 - sin^2θ)

Substituting these expressions into the integral, we have:

∫2^3 1x^3 √4x2 − x4 dx

= ∫sin⁡(θ=π/6)sin(θ=π/3) 8sin^3θ √(4sin^2θ)(4-sin^2θ) (2cosθ)dθ

= 16∫sin⁡(θ=π/6)sin(θ=π/3) sin^3θ cos^2θ dθ

We can use the identity sin^3θ = (1-cos^2θ)sinθ to simplify the integral further:

16∫sin⁡(θ=π/6)sin(θ=π/3) sinθ(1-cos^2θ)cos^2θ dθ

Now, we can make the substitution u = cosθ, du = -sinθ dθ, and use the table of integrals to evaluate the integral:

16 ∫u=-√3/2u=1/2 -u^2(1-u^2) du

= 16 [(-1/3)u^3 + (1/5)u^5]u=-√3/2u=1/2

= 16 [(-1/3)(-√3/2)^3 + (1/5)(-√3/2)^5 - (-1/3)(1/2)^3 + (1/5)(1/2)^5]

= 16 [(-√3/24) + (3√3/160) + (1/24) - (1/160)]
