Question: 1−cos2 x =
A. sin2x
B. -1

Sin^2 x

Step-by-step explanation:

Here, we want to evaluate;

1 - sin^2x

Mathematically ;

sin^2 x + cos^2 x = 1

Thus;

sin^2 x = 1 - cos^2 x

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
