Sin squared 30 + cos squared 30​

Step-by-step explanation:

Substitute in the expression,

\sin^230^\circ-\cos^230^\circ=(\frac{1}{2})^2-(\frac{\sqrt3}{2})^2sin

i do not know the answer i am sorry

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
