Answer:
4.116 × 108
Step-by-step explanation:
I simply used a Scientific Notation Converter
Average rate of change = change in y ÷ change in x
We already know the change in x because we are measuring the x values from -3 to 0.
change in x = 0-(-3) = 3
To find the change in y find the difference between the corresponding y-values when x=0 and when x=-3.
change in y = 0.5-2 = -1.5
average rate of change = -1.5/3 = -0.5
answer: -0.5
You can use trigonometry and the tangent to get:
tan(11°)=150/x
so x=772 ft
