Find f(x) when x = 0.
Plz help

0

Step-by-step explanation:

y=f(x)=-5^x

f(x)=-5^0

f(x)=0

final answer is : )

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
