Answer:
C.
Step-by-step explanation:
f(3) is referring to 3 on the left side and it is beside 1 which is on the left so it's 1.
the points (-6,0)(-2,0)(1,0)(3,0) all exist in the graph which is only correct for the second graph to make your self even more sure
since the zeros are given and it ia a polynomial you can figure out the facrored form
which will yield
f(x)=(x+6)(x+2)(x-1)(x-3)
conducting a simple sign test
------------------------------------------'
there will be 4 critical values
-6 -2 1 3
before -6 the sign of f(x) -*-*-*-= +
after -6 and before -2 the sign of f(x) +*-*-*-=-
after -2 and before 1 the sign of f(x) +*+*-*-=+
after 1 and before 3 the sign of f(x) +*+*+*-=-
after 3 the sign of f(x) +*+*+*+=+
which only fits the upper right graph
Here is how you do it so they asked 120 kids and 46 of them hangs out
on Saturdays so you just do this 46/120=38%
Answer:
44.44°
Step-by-step explanation:
A tower that is 101 feet tall casts a shadow 103 feet long. Find the angle of elevation of the sun to the nearest degree.
We solve this question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = ?
Opposite = Height of the tower = 101 feet
Adjacent = Length of the shadow = 103 feet
Hence
tan θ = 101/103
θ = arc tan (101/103
θ = arctan(0.9805825242718447)
θ = 44.438294667°
Approximately to the nearest degree = Angle of elevation = 44.44°
