The rise or an increase in altitude is represented by positive sign and a decend or decrease in altitude is represented by negative sign.
First the helicopter descended 1200 feet. So the change in altitude will be -1200 feet.
Then the helicopter rose by 800 feet. So the change in altitude will be 800 feet.
Finally the helicopter descended by 450 feet. So the change in altitude will be -450 feet.
The net change in altitude will be the sum of all the above 3 changes.
Change in altitude = -1200 + 800 - 450 = -850 feet
The negative sign indicates a descend i.e. loss in altitude. So the net change in altitude was a loss of 850 feet.
Step-by-step explanation:
We know, 9 to the power of 2 is 81
so it will be 81x
so its 81* a/b/c/d = 27/3 to the power of a/b/c/d +2

The equation would be 35.75x+6y=190
X intercepts are = 0 and 20
Maximum value = (10,15)
These can simply be read off of the graph.
The intervals of increasing from x = 0-10 and that shows the ball going up. Decreasing from 10-20 and that is the exact opposite.
The rate of change is often referred to as slope. The slope for the section described in part B is -1. It can be used by following the slope formula below:
y2 - y1/x2 - x1
