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 ).

Answer:
22°
Step-by-step explanation:
a right angle have 90°
So
x+68°=90°
=>x=90-68
=22°
Since x - 3 < 0 for -2 < x < 3, |x-3| = -(x-3)
Since x + 2 > 0 for -2 < x < 3, |x+2| = x+2
Since x - 5 < 0 for -2 < x < 3, |x-5| = -(x-5).
So y = -(x-3) + (x+2) -(-(x-5)) = 3 - x + x + 2 + x - 5 = x.
y = x, if -2 < x < 3.
