Answer:
The average rate of change between -1 and 2 is 1.
Step-by-step explanation:
To get this, use the two ordered pairs (-1, 5) and (2, 8). Now use the slope formula to find the rate of change.
m(slope) = (y2 - y1)/(x2 - x1)
m = (8 - 5)/(2 - -1)
m = 3/3
m = 1
The problem says that <span>Brandon sights a helicopter above a building that is 200 feet away at an angle of elevation of 30 degrees. So, you can calculate the height asked, by following this procedure:
</span>
Tan(α)=Opposite leg/Adjacent leg
α=30°
Opposite leg=x
Adjacent leg=200 feet
When you substitute these values into the formula above (Tan(α)=Opposite leg/Adjacent leg), you have:
Tan(α)=Opposite leg/Adjacent leg
Tan(30°)=x/200
You must clear "x":
x=200xTan(30°)
Therefore, the value of "x" is:
x=115 feet
<span>
How high above the ground the is the helicopter?
The answer is: 115 feet</span>
