What are the coordinates of the terminal point determined by t=10pi/3
1 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
so
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
therefore
the answer is the option D

Answer:
Length = 30
Height = 10
Step-by-step explanation:
Formula for the area = height * length. We know that the height of the wall is 1/3 of its length. This gives us another formula which is
Now substitute this into the formula, while knowing that the area is 300.
So we have 300 =
Solving for l gives us 30 and then substituting it back into the equation
, will give us that the height is 10.
Hope this helps
