Answer:
-1 < x < 0
Step-by-step explanation:
f(x) is a cubic function, so it can have up to 3 real zeros. The first option lists 4 intervals, which is too many.
Check the second option:
f(-1) = -6
f(0) = 7
f(x) changes signs between x=-1 and x=0, so there must be a 0 in that interval.
Answer:
68.2°
Step-by-step explanation:
AC is the longest side which means 90° is at B
SinA = BC/AC
sinA = 5/sqrt(29)
sinA = 0.9284766909
A = 68.19859051
A = 68.2°
