Complete the recursive formula of the arithmetic sequence -16, -33, -50, -67,...−16,−33,−50,−67,... c(1)=
c(n)=c(n-1)+

c(1)=-16

c(n)=c(n-1)+-17

Step-by-step explanation:

The first term is -16 and the difference of these numbers is -17.

Got it from Kahn Academy. :)

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
