1 answer:

6 0

Step-by-step explanation:

$v = \frac{4}{3} \pi {( \frac{19}{2} )}^{3} \\ v = \frac{4}{3} \pi \: 857.375 = 3591.364 \\ = 3591.4 \: {cm}^{3}$

Answer:

The correct answer option is H. 4374.

Step-by-step explanation:

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

The answer is D. In the function $y=4/(x-5)$ , A value of 5 would make the denominator 0. This is undefined, so 5 is excluded.
