Given the trigonometry expression:
sin 3x = sin(2x+x),
In trigonometry identity;

The expression above will then become;

Recall that sin^2x + cos^x = 1, hence;

This shows that

Answer:
B
Step-by-step explanation:
Reflect x-axis means (x,y) becomes (x, -y)
Shrink by 1/3 means f(x) = x becomes f(x) = 1/3x
Up 4 units means f(x) = x becomes f(x)= x + 4
So lets put that together




Answer:2(x/3-3) or 2(3-x/3)
Step-by-step explanation:
Answer:
3.24%
Step-by-step explanation:
Percentage error =[ (|calculated value - actual value) / actual value] x 100
calculated area = length x width
6.5 x 7.8 = 50.7
[(|50.7 - 52.4|] / 52.4] x 100 = 3,24
answer is side AB
I'm not 100% sure, just a guess
I hope it helps tho
