True, because "or" is a logical sum.
true = 1
false = 0,
sum (1+0) = 1, true.
down 3 unit mean -3 outside root
right 2 unit mean -2 inside root,
so the answer is

We write an inequality:



This equation cannot be solved using trivial methods found in high-school classes, so we resort to graphical examination.

is a linear function while

is an exponential one (with limit zero as

approaches

). We see that

at approximately

and

.
Indeed, using a computer algebra system such as the ones on modern TI calculators and on many internet sites gives equality at

. By observing our graph, we see that

when

or

.
Answer:
π/3 units
Step-by-step explanation:
arc length = 2πr(°/360)
= 2π*3(20/360)
= π/3 units
Answer:21
