height = 7 miles, base dimension is 190 miles
to find the angle on the ground up to the plane
use arctan(7/190)
acrtan on a calculator is tan^-1
arctan(7/190) = 2.1099 degrees. Round off as necessary
S=4. if r=10 than it would be 3(10)= 10+5s.
30=10+5s
20=5s
s=4
Answer:
B
Step-by-step explanation:
In this case the method of there being two of the same x values it is NOT a function. Because then there will be two points on top of each other resulting in it not passing the vertical line test on a graph.
