Answer:

5 ⋅ ( n + 1 )

Step-by-step explanation:

To write Five times the sum of a number and one you first make "a number" into a variable. In this case let's call it n

Next let's create the sum of a number and one. This would be:

n + 1

sum references addition

Then to get five times this number we need to multiple this expression by five to get: 5 ⋅ ( n + 1 )

Find the volume of a pyramid with a square base, where the side length of the base is 16.6m and the height of the pyramid is 9.1

aleksandrvk [35]

Answer:

Formula for volume of square pyramid:-

V = 1/3 x a^2 x h

Where 'a' is the length of one side of the base, and 'h' is the height.

Plug in our values, given that:

16.6m = side length of base.

9.1m = height of pyramid.

V = 1/3 x a^2 x h

V = 1/3 x 16.6^2 x 9.1

V = 1/3 x 275.56 x 9.1

V = 1/3 x 2507.596

V = 2507.596/3

V = 835.865, which rounds to 835.9 cubic meters.

In the graph of the inequality x > 2, what does a dashed line at x = 2 indicate?

ryzh [129]

Answer:

option 4: The line x = 2 is not included in the solution region is the correct option.

Step-by-step explanation:

Given the inequality

x > 2

It is clear that the given inequality is in the simple form which indicates that x is greater than 2.

Please check the attached graph.

As x is greater than 2, thus a dashed line at x = 2 on the graph indicate indicates that x = 2 is not included in the solution region.

Please remember that inequalities that use < or > symbols are drawn with a dashed line in order to display that line is not included in the region.

Thus, the solution to the inequality is:

$x>2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x>2\:\\ \:\mathrm{Interval\:Notation:}&\:\left(2,\:\infty \:\right)\end{bmatrix}$

The solution indicates that that the value of x will be greater than 2.

Please check the attached graph.

A dashed line at x = 2 on the graph indicates that x = 2 is not included in the solution region.

Hence, option 4: The line x = 2 is not included in the solution region is the correct option.
