Answer please. i need help

B

Step-by-step explanation:

For this problem, it would be wise to actually graph the two equations on a graphing calculator.

Doing so, you see that, indeed, both the graph and are the same.

However, looking back at the original problem, we see that we're looking for solutions where   is less than . Since the graph shows that all the solutions of the first equation are the solutions for the second equation, as well, there are NO solutions that make the first equation smaller than the second.

Hence, the answer is (b) because it is the only one that gives the correct answer and explanation.

Option 2

Step-by-step explanation:

2sin²x + cos(2x) - 2 < -1

2sin²x + (1 - 2sin²x) - 2 < -1

2sin²x + 1 - 2sin²x - 2 + 1 < 0

0 < 0

Is a false statement

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
