What are the coordinates of the terminal point determined by t= 10 pie/3

1 answer:

5 0

Answer:

we know that

10*pi/3------> convert to degrees------> 10*180/3=600 degrees

600=360+240

240 degrees belong to the III quadrant

the x-coordinate is negative

the y-coordinate is negative

240°=180°+60°

60 degrees is the angle to find the terminal point

let

∅=60°

in the unit circle

r=1 units

x=-r*cos ∅----> x=-cos 60------> x=-(1/2)

y=-r*sin ∅----> y=-sin 60------> y=-(√3)/2

the point is

-1/2,-√3/2

the answer is the option A

Answer:

Step-by-step explanation:

To know the future value of an specific amount that is borrowed from a bank we use the following equation: $FV= PV\imes{(1+n\times{i})}$ , where FV is future value, PV present value, n the amount of periods and i the interest rate.
In this particular case, the present value of the loan is $400, n=4 (4 years), i=5%. Then the future value equals: $FV= 400\times(1+4\times0.05)$ . Then FV= $480, which is the total amount of money she would have to return in 4 years.
The interest paid can be calculated as the total amount paid ($480) minus the inicial loan ($400), which means that total interests paid= FV- PV= $80.
