Answer:
5.236 units
Step-by-step explanation:
The relation between r, θ and arc length ( l ) is,
l = rθ
l = 1 * 5π / 3
( The value of π = 3.14 approximately )
5π = 5 x 3.14 = 15.7
l = 1 * 5π / 3
= 5π / 3
= 15.7/3
l = 5.236 units
Note : -
Arc length is denoted by " l ".
Answer:
f(g(2)) = -11
Step-by-step explanation:
f(g(2))=
First we need to find g(2)
g(x) = 3x-4
We let x=2
g(2) = 3(2) -4
6-4
=2
Now we stick the value of g(2) in for x in f(x)
f(x) = -2x^2 - 3
f(2) = -2(2)^2 -3
=-2 (4) -3
= -8 -3
=-11
