Answer:
80 miles
Step-by-step explanation:
Speed is 30 miles/hour
Time is 2 hours 40 minutes or 2 2/3 hours or 8/3 hours
Distance is speed x times
so distance is 30 x 8/3 = 80 miles
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
Answer:
34°
Step-by-step explanation:
The measure of vertical angles formed by two chords is equal to one half the sum the measures of the arcs.
In other words, x is the average:
x = (23° + 45°) / 2
x = 34°
Actually Welcome to the Concept of the Functions.
so after plotting the graphs, we get as,
==> m = 2.5
==> b = 0
==> y = mx+c
a straight line
