Answer:

\Delta z = 1.2\cdot \Delta t, \Delta z = 36\,in

Explanation:

The total water level lost due to evaporation is directly proportional to the number of day. That is:

\Delta z = k \cdot \Delta t

Where k is the proportionality constant, which is equal to \frac{1}{2}\,\frac{in}{day}. The expression is:

\Delta z = 1.2\cdot \Delta t

And the total change in water level after 30 days is:

\Delta z = 1.2\cdot (30\,days)

\Delta z = 36\,in

Answer:

1. (x-4), (y+4)

2. In a transformation, the equation shows how much the original coordinate moves. In the equation above, the orignal coordinate would move to the left 4 places, and then up 4 places. This particular transformation is called a translation, as the shape is the same but only in a different spot.

3. Quadrilateral

4. The transformed polygon has the apostrophes after each letter, which means it is "prime" or not the original.

Explanation:

1. To write the equation, look at how the shape shifts. If the x coordinate moved 4 spaces to the left, then that means the equation is -4. Do the same for the y-coordinate, except keep in mind it is up and down instead of left or right.

2. The answer is self-explanatory.

3. A quadrilateral has 4 sides, and this can be applied to more specific shapes, such as a square or rectangle. Because this shape has no distinctive features, it is safest to call it a quadrilateral.

4. The answer is self-explanatory.
