In Exercises 27 and 28, find the domain of the function
Natali5045456 [20]

                                             Question 27

The graph on question 27 indicates that there are three points with the locations such as:

  • (2, 6)
  • (4, 12)
  • (6, 18)

In other words, there are three points that lie on the graph with the x-values such as:

{(2, 6), (4, 12), (6, 18)}

We know that the domain includes the set of x-values.

Hence, the domain of the function is:

  • Domain: {2, 4, 6}

Since the points are not connected between them. In other words, there is not a continuous line.

Thus, the function represented on the graph has a discrete domain.

                                        Question 28

The graph on question 27 indicates that the line segment with the end-points (0, 25) and (7, 20).

Since there is a continuous line between the points from x = 0 to x = 7.

Thus, the domain of the line function is:

  • Domain: {0, 1, 2, 3, 4, 5, 6, 7}

As the line segment is a continuous line. Thus, the domain is continuous.

A pyramid with a slant height 4.6 in whose triangular base measures 8 in on each side.Each altitude of the base measures of 6.9
kvasek [131]

Answer:

82.8 in²

Step-by-step explanation:

The surface area a triangular based pyramid :

Base area + 1/2(perimeter * slant height)

Base = 8 inches ; Slant height = 4.6 inches ; altitude of base measure = 6.9 inches

Base area of triangle :

1/2 * base * height

1/2 * 8 * 6.9

4 * 6.9

Base area = 27.6 in²

The perimeter, P = sum of sides ; (s1 + s2 + s3

P = 8 + 8 + 8 = 24 in

Hence,

Surface area = 27.6 in² + 1/2(24*4.6)

Surface area = 27.6 in² + (12 * 4.6) in²

Surface area = (27.6 + 55.2)

Surface area = 82.8 in²

Use the Properties of Equality to solve each equation.
castortr0y [4]
The answer is -25

All you have to do is add -6-9 which equals -25 because “same signs add(+) and keep” “different signs subtract(-)” but “add” means positive number and “subtract” means negative number. Since they are different signs a (+) and a (-) you subtract it.

Hope this helps!

67,124 x = ________. Will the product of this equation be less than or greater than 67,124? Explain your reasoning.
sweet-ann [11.9K]

The product could be either less than or greater than 67,124.

If you multiplied by a negative number, you would get a negative number, which is less than a positive number such as 67,124.

If you multiplied by zero, you would get zero, which is less than a positive number such as 67,124.

If you multiplied by one, you would get 67,124, which is equal to 67,124 since they are the same number.

If you multiplied by a positive number less than one, you would get a positive number greater than zero and less than 67,124.

If you multiplied by a positive number greater than one, you would get a positive number greater than 67,124.
