Answer:

  726 feet

Step-by-step explanation:

Object height and shadow length are proportional, so you have ...

  (object height)/(shadow length) = (18 ft)/(72 ft) = (dam height)/(2904 ft)

Then the dam height is ...

  dam height = (2904 ft)(18/72) = 726 ft

Hoover Dam is 726 feet high.

In 1905 the Colorado River flooded parts of Nevada. It ruined crops, roads, and buildings. Water covered the land for an entire year. To stop the flooding, the construction of the Hoover Dam began. The dam controlled the river and brought water to the cities. It was completed in 1935. It took 5,000 workers and 5 years to build. Hoover Dam is 1,244 feet long and 726 feet high.

Write 0.0059 in scientific notation.
polet [3.4K]
Hi!

When we write a number in scientific notation, we write it like this:
N × 10^{x}

N = a number between one and 10
x = negative if the decimal is moved to the right. positive if moved to the left.

Okay, so we need to move the decimal in the number <span>0.0059 to the right to make it between one and 10.
0.0059
00.059
000.59
0005.9
5.9

N = 5.9
5.9 </span>× 10^{-x}

Since we moved the decimal to the right 3 times,
x = -3

5.9 × 10^{-3}
^ the answer

Hope this helps! :)

Can some help please?!?!

Answer:

<em>Choice D.</em>

Step-by-step explanation:

Vertical line test for functions:

If a vertical line drawn anywhere on the graph intersects the graph in more than one point, it is not a function.

If you draw a vertical line passing through any point between x = -4 and x = 4, the line will intersect two points on the circle. The relation fails the vertical line test. That shows that this relation is not a function.
