Can i please have help with number 6

Allisa [31]

Length of the diameter = sqrt ( (-12- (-8)^2) +(2-0)^2) )
= sqrt (16 + 4) = sqrt20
so radius = sqrt 20 / 2 = sqrt5
so r^2 = 5

Center of the circle = coordinates of the midpoint of the diameter =

-8-12/2 , 2-0 / 2 = (-10, 1)

(x - a)^2 + (y - b)^2 = r^2 is general form of a circle so here the circle is:_

(x + 10)^2 + (y - 1)^2 = 5 Answer

Its B

Using sigma notation write the geographic series: 6+12+24+48+96

Alika [10]

Answer:

$\sum_{n=1}^{5} 6(2^{n-1})$

Step-by-step explanation:

6 + 12 + 24 + 48 + 96 =

= 6 + 6 * 2 + 6 * 4 + 6 * 8 + 6 * 16

= 6 + 6 * 2^2 + 6 * 2^2 + 6 * 2^3 + 6 * 2 * 4

= 6 * 2^(n - 1)

$\sum_{n=1}^{5} 6(2^{n-1})$
