Answer:

<h3> (x³+2x²)/3 cm³</h3>

Step-by-step explanation:

Find the diagram attached

Volume of a pyramid = 1/3 * Base area * height

Base area = x*x

Base area = x²

Height = x+ 2

Get the volume:

Volume of the pyramid = 1/3 * x² * x+2

Volume of the pyramid =  x²(x+2)/3

<em>Volume of the pyramid  = (x³+2x²)/3 cm³</em>

Question that i dont know
lutik1710 [3]

Answer:

A translation of 3 units to the right and a translation of one unit upwards.

Step-by-step explanation:

When we analyze translations of whole figures, all the points in the figure suffer the same translation, then we only need to analyze the translation of one of the points.

This means that we can only see the translation from A to A'

First, let's find the coordinates of each point:

A (2, 3)

A' (5, 4)

The translation is given if we calculate the difference between these coordinates:

A' - A =  (5, 4) - (2, 3) = (5 - 2, 4 - 3) = (3, 1)

The change in the x-value is 3.

The change in the y-value is 1.

Then we can conclude that:

A' is 3 units at the right of A

A' is 1 unit above A.

Then the translation is:

A translation of 3 units to the right and a translation of one unit upwards.

Ksenya-84 [330]

Answer:

  D. The graph of g(x) is the graph of fix) translated to the left 7 units and up 9 units

Step-by-step explanation:

The transformation of f(x) to g(x) ...

  g(x) = a·f(b·x -c) +d

involves ...

  • vertical expansion by a factor of "a"
  • horizontal compression by a factor of "b"
  • translation to the right by "c" units
  • translation up by "d" units

Here, you have a=b=1, c=-7, d=9, so the graph of f is translated left 7 units and up 9 units to make the graph of g.

A cruise ship travels 300 miles due east. It travels 175 miles along it's new course. How far is the cruise ship from it's initi
Akimi4 [234]
The answer depends on where the ship starts from. If it starts on the equator, the answer is 459.938 miles.
If it starts at 70° N, then the distance is 446.084 miles.
And if the ship is on a flat earth, the distance is 459.954 miles (very close to the distance on a round Earth starting at the equator). Hope this helps!
