Answer:
Step-by-step explanation:
From the given question,
a). m∠WAX = 60°
If m(arc WX) = 100°
Then by theorem,
Angle formed between the chords in a circle, measures the half of the sum of intercepted arcs.
m(∠WAX) =
60° =
120 = 100 + arc YZ
120 - 100 = arc YZ
m(arc YZ) = 20°
b). m(arc WX + arc YZ) = 2(60°)
m(arc WX + arc YZ) = 120°
Hello :
<span>If f(x) = x + 8 and h(x) = 3x − 3,
</span><span>g ∘ f = h
</span>g ∘ (f ∘ f ^-1) = h ∘ f ^-1 ( proprety associative)
but ;
(f ∘ f ^-1) = x
g ∘ x = g
g(x) = (h ∘ f ^-1)(x)
calculate : (f ^-1)(x)
f(x) = x +8
x= f(x) - 8
so : (f ^-1)(x) = x - 8
g(x) = (h ∘ f ^-1)(x) = h((f ^-1)(x)) = h(x - 8) = 3(x - 8) -3
g(x) = 3x - 27
The answers are A, C, and E because during those intervals the slope is negative
