Answer:

Step-by-step explanation:

the n th term ( explicit formula ) of a geometric sequence is

• $a_{n}$ = $a_{1}$ $(r)^{n-1}$

where r is the common ratio and $a_{1}$ the first term

here r = $\frac{8}{16}$ = $\frac{16}{32}$ = $\frac{1}{2}$ and $a_{1}$ = 64, hence

$a_{n}$ = 64 $(0.5)^{n-1}$ → D

Find the distance between the points (-9,0) and (2,5)

andreev551 [17]

Answer:

sqrt(146)

Step-by-step explanation:

The distance between these two points can be the hypotenuse of our right triangle.

We can create a right triangle with two legs of length 11 and 5. To solve for the hypotenuse, we apply the pythagorean theorem

sqrt(5^2+11^2)=sqrt(146)

I attached a graph to help you visualize the triangle and how it works.
