H(t)=(t+3)^2+5 Over which interval does h have a negative average rate of change?
Yuri [45]

Answer:

( -∞, -3 ) or any subinterval of  ( -∞, -3 )

Step-by-step explanation:

h(t)=(t+3)^2+5 has the form

h(t) =(t-h)^2 + 5, indicating that h(t)=(t+3)^2+5 represents a parabola with vertex at (-3,5) that opens up.  This (-3,5) is the minimum point of the graph.

To the left of t = -3, h(t) is decreasing; to the right of t = -3, h(t) is increasing.

Thus, it is on any interval to the left of t = -3 that the rate of change of this function is negative (the function is decreasing  on ( -∞, -3 ).

If a=(-2 -4) and b=(-8 4) what is the length of AB
Lady_Fox [76]

Use the distance formula Sqrt ( (x2-x1)^2 +(y2-y1)^2)

Distance = sqrt ( (-8 - -2)^2 +(4- -4)^2)

Distance = sqrt(-6^2 + 8^2)

Distance = sqrt ( 36 + 64)

Distance = sqrt(100)

Distance = 10

The length is 10
