Which statement best describes how to determine whether f(x) = x3 + 5x + 1 is an even function?
determine whether –(x3 + 5x + 1) is equivalent to x3 + 5x + 1.
determine whether (–x)3 + 5(–x) + 1 is equivalent to x3 + 5x + 1.
determine whether –x3 + 5x + 1 is equivalent to –(x3 + 5x + 1).
determine whether (–x)3 + 5(–x) + 1 is equivalent to –(x3 + 5x + 1).

The answer is B) Determine whether (–x)^3 + 5(–x) + 1 is equivalent to x^3 + 5x + 1

or

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
