You could make an infinite number of triangles.
Answer:
Substitute y with y+10 and x with x-4.
Step-by-step explanation:
To shift every point in the plane 10 down you have to substitute y with y+10 and to shift every point in the plane 4 units right you have to substitute x with x-4.
Suppose the origin of function on the plane is (0,0) now we have to make the origin (4,-10).
first (x,y)=(0,0)
When we substitute x and y
(x-4,y+10)=(0,0)
x-4=0
x=4
y+10 = 0
y= -10
Now the origin is (4,-10).
Hence the function is shifted 10 units down and 4 units right.
Hello,
A)
cos 135°=- cos 45°=-√2/2
sin 135°=sin45°=√2/2
2(cos 135°+i sin 135°)=-√2 + i*√2
B)
cos 120°=-cos 30°=-√3 /2
sin 120°=sin 30°=1/2
3(cos 120° + i sin 120)=-3/2*√3 +i*3/2
C)
cos (5π/4)=-cos (π/4)=-√2 /2
sin (5π/4)= -sin(π/4)=-√2 /2
5(cos (5π/4)+i sin (5π/4))=-5/2*√2 +i *5/2*√2
D)
cos(5π/3)=cos(π/3)=√3 /2
sin (5π/3)=-sin(π/3)=-1/2
4(cos(5pi/3)+i sin (5pi/3))
=2√3- 2*i
100 : 1 = x : 0.2
x = 100 * 0.2 : 1
x = 20
