Consider the inequality cos(2x) 0 by picking a value for x from each interval. She finds the following. cos(2x)>0 from 0 to π4 cos(2x) 0 from 3π4 to 5π4 Finally, Milan concludes that cos(2x)<0 on the interval [π4,3π4]. Part A: Which answer choice shows the correct analysis of Milan’s work? Part B: What is the domain of the inequality? Part C: What is the solution set for the inequality?

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

the answer is a.
