Answer:

Dolphin is 3 feet above the surface of the water.

Step-by-step explanation:

Dolphin is 30 feet below the surface of the water, then its position on the vertical number line is -30.

  • She rises 23 feet - add 23,
  • sinks 17 feet - subtract 17,
  • and finally rises another 27 feet - add 27.

Thus,

-30+23-17+27\\ \\=(-30-17)+(23+27)\\ \\=-47+50\\ \\=3

Dolphin is 3 feet above the surface of the water.

Let me know the answer plz
Gala2k [10]

<u>Answer:</u>

The correct answer option is H. 4374.

<u>Step-by-step explanation:</u>

We are given the following geometric sequence and we are to find its 8th term:

\frac{2}{9}, \frac{2}{3}, 2,...

Here a_1=\frac{2}{9} and common ratio (r) = \frac{\frac{2}{3} }{\frac{2}{9} } =3.

The formula we will use to find the 10th term is:

nth term = a_1 \times r^{(n-1)}

Substituting the values in the formula to get:

10th term = \frac{2}{9} \times 3^{(10-1)}

10th term = 4374
