Answer:

The nearby building is $135 \dfrac{5}{9}$ feet tall.

Step-by-step explanation:

The statue of liberty is 305 feet tall.

A nearby building is $\dfrac{4}{9}$ as tall as the statue of liberty.

To find the height of the building, you need to find $\dfrac{4}{9}$ of 305:

$\dfrac{4}{9}\cdot 305=\dfrac{1,220}{9}= 135 \dfrac{5}{9}\ feet$

Thus, the nearby building is $135 \dfrac{5}{9}$ feet tall.

Answer:

Step-by-step explanation:

The explicit rule for a geometric sequence is

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 64 and r = $\frac{a_{2} }{a_{1} }$ = $\frac{128}{64}$ = 2 , then

$a_{n}$ = 64 $(2)^{n-1}$ → B
