Answer:
Distance from the airport = 894.43 km
Step-by-step explanation:
Displacement and Velocity
The velocity of an object assumed as constant in time can be computed as
Where is the displacement. Both the velocity and displacement are vectors. The displacement can be computed from the above relation as
The plane goes at 400 Km/h on a course of 120° for 2 hours. We can compute the components of the velocity as
The displacement of the plane in 2 hours is
Now the plane keeps the same speed but now its course is 210° for 1 hour. The components of the velocity are
The displacement in 1 hour is
The total displacement is the vector sum of both
The distance from the airport is the module of the displacement:
Answer:
6 periods
Step-by-step explanation:
The investment is compounded semi-annually which means it is compounded twice in a year. Period of investment is 3 years. So, number of periods compounded is 3 multiplied by 2 that is 6 periods.
Rate would be 8% divided by 2 that is 4%.
Initial investment can be calculated usinf spreadsheet function as =PV(rate,nper, pmt, FV)
Where,
rate is 0.04
nper is 6
pmt is 0
FV is 7,000
So, initial investment is $5,532.20.
It is negative as it is a cash outflow.
The answer is 85$ because .25 times 200 is 80 plus 35 is 85
So what you do is make a fraction with the conversation between miles and km with km on the bottom to cancel out the units and multiply the fraction by the amount of km
5km (.62miles/1km) = 3.1 miles
7 is the answer to this question
