Answer: An obstacle course is a series of challenging physical obstacles that must be completed in order to finish the course. To find out how many kilometers long the obstacle course is, you need to add up the distance that Caleb runs, jumps crawls, and dribbles.

First, we need to convert the 500 meters to kilometers by dividing it by 1000.

500 meters / 1000 = 0.5 kilometers

Then, we need to add the distance that Caleb crawls through the tunnel, which is 20 meters.

20 meters = 0.02 kilometers

Finally, we need to add the distance that Caleb dribbles the soccer ball, which is 100 meters.

100 meters = 0.1 kilometers

To find the total distance of the obstacle course, we need to add the distance that Caleb runs, jumps, crawls, and dribbles:

0.5 + 0.02 + 0.1 = 0.62 kilometers

So the obstacle course is 0.62 kilometers long.

The vectors generated by means of operations with canonical vectors:

Herein we find three canonical vectors, one for each orthogonal axis, from which we need to perform operations to generate new vectors. There two fundamental operations:

Vector sums

(a, b, e) + (c, d, f) = (a + c, b + d, e + f)

Vector multiplication by a scalar

α · (a, b, c) = (α · a, α · b, α · c)

Where:

If we know that U = (5, 0, 0), V = (0, 5, 0) and W = (0, 0, 5), then the following operations are below:

Case 1

U + V + 2 · W

(5, 0, 0) + (0, 5, 0) + 2 · (0, 0, 5)

(5, 0, 0) + (0, 5, 0) + (0, 0, 10)

(5 + 0 + 0, 0 + 5 + 0, 0 + 0 + 10)

(5, 5, 10)

Case 2

U + T = V

T = V - U

T = (0, 5, 0) - (5, 0, 0)

T = (0 - 5, 5 + 0, 0 + 0)

T = (- 5, 5, 0)

Case 2b

R = U + V + W

R = (5, 0, 0) + (0, 5, 0) + (0, 0, 5)

R = (5 + 0 + 0, 0 + 5 + 0, 0 + 0 + 5)

R = (5, 5, 5)

Case 3

T - 2 · R

(- 5, 5, 0) - 2 · (5, 5, 5)

(- 5, 5, 0) + (- 10, - 10, - 10)

(- 5 - 10, 5 - 10, 0 - 10)

(- 15, - 5, - 10)

Case 3b

S = U + W

S = (5, 0, 0) + (0, 0, 5)

S = (5 + 0, 0 + 0, 0 + 5)

S = (5, 0, 5)

Case 4

U + V + W + R + S + T

(5, 0, 0) + (0, 5, 0) + (0, 0, 5) + (5, 5, 5) + (5, 0, 5) + (- 5, 5, 0)

(5 + 0 + 0 + 5 + 5 - 5, 0 + 5 + 0 + 5 + 0 + 5, 0 + 0 + 5 + 5 + 5 + 0)

Based on the graph of this quadratic function with vertex (-1, -4), the domain and the range are as follows;

Domain = {-3, 0.5}.

Range = {-4, ∞}.

In Mathematics, the horizontal extent of any graph of a function represents all domain values and they are read and written from smaller to larger numerical values, and from the left of a graph to the right.

Additionally, the vertical extent of any graph of a function represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.

Note: The vertex of any quadratic function represents the minimum of the given function.

By critically observing the graph shown in the image attached below, we can reasonably and logically deduce the following:

Domain = -3 < x < 0.5 or [-3, 0.5].

Range = -4 < y < ∞ or [-4, ∞].

Since George can build a laptop twice as fast as Kurt and working together takes them 3 hours, an equation which you would use to determine how long it will take Kurt working alone is: D. 1/t + 1/2t = 1/3.

In order to determine the amount of time it would take Kurt working alone, we would have to assign variables to the amount of time taken by George to build a laptop and the amount of time taken by Kurt to build a laptop, and then translate the word problem into an algebraic equation (expression) as follows;

Since George can build a laptop twice as fast as Kurt, an equation which models this situation is given by;

g = 2t     .....equation 1.

Next, we would write an algebraic equation (expression) that models the combined work rate;

1/c = 1/t + 1/g     .....equation 2.

Substituting equation 1 into equation 2, we have the following:

[tex]g \left( f \left( g \left( 0 \right) \right) \right)=3[/tex]

We had to use the equation on the first problem as the graph does not show the value of function f(x) when x = -6.

Step-by-step explanation:

When calculating composite functions, work from the inside out.

Given composite function:

[tex]f \left( g \left( f \left( 1 \right) \right) \right)[/tex]

First use the graph to find f(1):

[tex]\implies f \left( g \left( f \left( 1 \right) \right) \right)= f \left( g \left(-4\right)\right)[/tex]

Now use the graph to find g(-4):

[tex]\implies f \left( g \left(-4\right)\right)=f(-6)[/tex]

As the graph does not show the value for f(x) when x = -6, we need to use the equation:

[tex]\implies f(-6)=(-6)^2-2(-6)-3=45[/tex]

Therefore:

[tex]f \left( g \left( f \left( 1 \right) \right) \right)=45[/tex]

------------------------------------------------------------------------------

Given composite function:

[tex]g \left( f \left( g \left( 0 \right) \right) \right)[/tex]

First use the graph to find g(0):

[tex]\implies g \left( f \left( g \left( 0 \right) \right) \right)=g \left( f \left( -2 \right) \right)[/tex]

Now use the graph to find f(-2)

[tex]\implies g \left( f \left( -2 \right) \right)=g \left(5 \right)[/tex]

Finally, use the graph to find g(5):

Therefore:

[tex]g \left( f \left( g \left( 0 \right) \right) \right)=3[/tex]

We had to use the equation on the first problem as the graph does not show the value of function f(x) when x = -6.

Answer: 5/8 "=" 10/16

Step-by-step explanation: To compare the fractions 5/8 and 10/16, we need to find a common denominator. In this case, the least common multiple of 8 and 16 is 16.

So, we can write the fractions as:

5/8 = (52)/(82) = 10/16

So the fractions are equal, therefore, the symbol that correctly compares them is = (the equal sign).

Answer: =

Step-by-step explanation:

In order to compare the fractions, we must make sure that the fractions have common denominators. Because 8 is a factor of 16, we will convert 5/8 into a fraction that has a denominator of 16. To do this, we need to multiply the numerator and denominator by the same number, in this case, 2 since that is what multiplies by 8 to get 16. (5/8) * (2/2) = 10/16 (you can just multiply across the top and bottom to solve). Now, we can compare. 10/16 is the same as 10/16, so an = would be the appropriate symbol. Hope this helps!

Answer:

The domain of a function is the set of all input values (x-values) for which the function produces a valid output (y-value). In the case of the function H(x) = x+2/x^2+4x+4, we need to find the values of x for which the denominator x^2+4x+4 is not equal to zero.

x^2+4x+4 = 0

(x+2)^2 = 0

The denominator is always non-zero as the square of any real number is always positive. Therefore, the function H(x) = x+2/x^2+4x+4 is defined for all real values of x. Therefore, the function H(x) does not have any values that are not in its domain.

Team Tackle's score was 28 points. And team Sack's score was 9 points.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

During the 2005 football season, Team Tackle beat Team Sack by 19 points. If their combined scores totaled 37.

Let 'x' be the Tackle's score and 'y' be the Sack's score. Then the equations are given as,

x + y = 37        ...1

x = y + 19        ...2

From equations 1 and 2, then we have

y + 19 + y = 37

2y = 18

y = 9

Then the value of 'x' is given as,

x = 9 + 19

x = 28

Team Tackle's score was 28 points. And team Sack's score was 9 points.

By using the fact that the sum of the interior angles must be 180°, we wil see that:

x = 110°.

First, remember that the sum of the interior angles of a triangle is alway equal to 180°.

We also can see that the interior angle that is adjacent to x can be written as:

a = 180° - x

Then the sum of the interior angles will give:

30° + 80° + (180° - x) = 180°

30° + 80° - x = 0

110° - x = 0

3y = 4x + 2 is a linear equation that satisfies the graph.

A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.

Given, Few coordinates of a linear function to make the equation of line we need only two coordinates.

general formula for linear equation is y = mx + c

where, m = slope

c = constant

General formula for slope m = (y₂ - y₁)/(x₂ -x₁)

Since graph passes through the points(3, 6) and (0, 2)

Slope m = (2 - 6)/ (0 - 3)

m = -4/-3 = 4/3

Thus, equation of line will be

y = 4/3x + c

Since the Line passes through (0, ,2 ) these point will satisfy the above equation

2 = 4/3 * 0 + c

=> c = 2
