Answer:
Step-by-step explanation:
Given
Balloon velocity is 14 ft/s upwards
Distance between balloon and cyclist is 140 ft
Velocity of motor cycle is 88 ft/s
After 10 sec
motorcyclist traveled a distance of 
Distance traveled by balloon in 10 s

net height of balloon from ground =140+140=280 ft[/tex]
at 
distance between cyclist and balloon is 

now suppose at any time t motorcyclist cover a distance of x m and balloon is at a height of h m
thus 
differentiating w.r.t time





Answer:
correct option is B. 10%
Step-by-step explanation:
given data
assets A annualised volatility = 10%
assets B annualised volatility = 20%
solution
we both A and B assets are 10% and 20% respectively
and we know that to achieve smallest portfolio volatility
we need to invest completely in the asset which has least volatility
and volatility can not be less than the asset having least volatility
so here minimum volatility that can be achieved is = 10%
so correct option is B. 10%
