Answer:
73.77 ft/s
Step-by-step explanation:
Let's imagine this situation as a right triangle where the distance between the two points is the hypotenuse.
-Applying Pythagoras theorem:
#Take the derivative of the first equation and solve for 
:
#We then substitute the values given in the question to solve for :
Hence, the rate of change of the distance between the motorcycle and the balloon 7 seconds later is 73.77 ft/s
Answer:
105 degrees

Answer:
The volume of the sphere is 288π in³
Step-by-step explanation:
To calculate the volume of a sphere we have to use the following formula:
V = volume
r = radius
V = ⁴⁄₃πr³
V = ⁴⁄₃ * π * (6in)³
V = π * ⁴⁄₃ * 216 in³
V = 288π in³
The volume of the sphere is 288π in³
