Answer:
8.1 inches
Step-by-step explanation:
Proportion of angle to the whole circle:
(13π/18)/2π=13/36
13/36=18.4/2rπ
13/36=9.2/rπ
13rπ=331.2
rπ=25.47
r=8.1
probably -3, -1 bc it is local to origin and the minimum in that situation. I just got into this topic myself so I'm not exactly sure
M
f(x) = 1/4x-3
When f(x) = -1,
= 1/4(-1)-3
= -13/4
