Answer:
34 minutes I think is the right answer
A = 31 degree
Cos 31 degree = 400/x
X = 400/ Cos 31
= 400/0.8572
= 466.7ft
The average rate of change over some interval [a, b] is equal to the slope of the secant line from (a, h(a)) to (b, h(b)).
h(t) is a quadratic function, so its graph is a parabola, and in particular it's one that has a minimum of -4 when t = 2.
The secant line over an interval [a, b] will have a negative slope if the distance from a to 2 is larger than the distance from b to 2.
(A) If a = 4 and b = 5, then |a - 2| = 2 and |b - 2| = 3, so the slope and hence average rate of change is positive.
(B) If a = -1 and b = 5, then |a - 2| = 3 and |b - 2| = 3, so this ARoC is zero.
(C) If a = 0 and b = 4, then |a - 2| = 2 and |b - 2| = 2, so this ARoC is also zero.
(D) If a = -1 and b = 4, then |a - 2| = 3 and |b - 2| = 2, so this ARoC is negative.
Answer:
<em>-4/5,-1/2,-0.2,0.25</em>
Step-by-step explanation:
To order these, it would be best to convert them into decimals.
-4/5 is equal to -0.8
-1/2 is equal to -0.5
-0.8 is the least, because the further left on a number line, the less the number is.
-0.5 is next and then -0.2
Finally, 0.2 is the greatest
<em>-4/5,-1/2,-0.2,0.25</em>
