Which of the following is the common difference and the nth term rule for the sequence: 5,−3,−11,…? Select one:
d=−8 and an=−8n+13
d=8 and an=8n+13
d=−7 and an=−7n+13
d=7 and an=7n+13

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
