Cross multiply the expression so that we can get
(1+sinx)(1-sinx) = cos^2 x
1 - sin^2 x = cos^2 x
cos^2 x + sin^2 x = 1
since
cos^2 x + sin^2 x = 1
therefore
1 = 1
the two expressions are identical in a trigonometric sense
Answer:
It would be the last one 6x+7209
Step-by-step explanation:
because it will be simplify not factor by
A. The independent variable is time, as time is manipulating the value of her salary.
b. The dependent variable is her cost because what she charges for babysitting depends on how long she works.

You haven't given us any choices. Always do that it you have them. Look for the graph that looks like the one below. It has the following characteristics
- It opens upward
- It lowest point is -1,1
- y never equals zero
- The y intercept is 0,4
